4.6 Cooling lubricant

4.6.1  Overview

The following instructions comply with the documentation

"Standard 3.9 / Cooling Lubricant" stipulates.

4.6.1.1 Concept

Cooling lubricants are materials used for cooling and lubrication during chip processing of materials with a specified or unspecified cutting edge or during shape change processing. (DIN 51385)

The water-soluble cooling lubricant should be mixed with water before use. This can be a solution or emulsifier.

• Emulsion (cooling lubricant containing mineral oil or ester oil) contains substances (mainly emulsifiers) that can form a stable emulsion with water.
• The solution (cooling lubricant without mineral oil) consists of water-soluble substances, such as glycol.
• The non-water-soluble cooling lubricant consists of mineral oil or ester oil.
• Both water-soluble and non-water-soluble cooling lubricants contain additives for improving properties, mainly:
• Sulfur, ester and phosphorus, (because chlorine is easy to form acid and residue, it will not be used in the future).
• Sterilizers, rust antiseptics.
•  Defoamer 
• A substance used to stabilize the pH value.
• Anti-rust additives used to temporarily prevent machine tool rust in water-soluble cooling lubricants.

4.6.1.2 Application of cooling lubricant

The cooling lubricant is hereinafter referred to as KSS for short.

Non-compliance with accident prevention regulations.

• Work on KSS equipment must comply with local labour protection regulations and accident prevention regulations, especially in Germany with BGR (Occupational Insurance Federation Safety and Health Regulations) 143!
• Ambient temperature:
• The specified working temperature of the machine is 15°C to 35°C. If temperature conditions do not match, such as tropical climate packages and cooling lubricant equipment with thermostatic treatment!
• In order to achieve the highest accuracy, the temperature should be kept constant during processing (see also the precautions in this operation manual). When higher precision is required, it is recommended to perform constant temperature treatment on KSS.
• Dirty KSS:
• KSS can shorten its service life when it is dirty.
• Never bring in chemicals, impurities or trash.
• Humid condition:
• Humidity must be avoided as it can prompt rust. Therefore, when the machine stops using, you should open the processing area door and operating door in order to give the machine ventilation.
• Work on KSS related work:
• Wearing the necessary protective supplies when doing work related to KSS! Be aware to comply with the processing requirements of KSS and secure data forms.

Warning! Material with a risk of explosion!

Use KSS with a flammable liquid that accounts for more than 15% by volume.

There is a risk of injury, and fire, explosion or microburst may cause death or serious injury.

• Additional comprehensive explosion protection measures or special optimization measures for the machine are required.

Warning! Material with a risk of explosion!

When processing light metals and light alloys, especially when metals or alloys contain magnesium, can generate spontaneous or explosive particles.

There is a risk of injury, and fire, explosion or microburst may cause death or serious injury.

• Additional comprehensive explosion protection measures or special optimization measures for the machine are required.

4.6.1.3 Selection and maintenance of cooling lubricants

Only by selecting the right KSS and maintaining it professionally can ensure that there is no problem.

Use boron-containing KSS.

According to the current level of inspection (2013 research project), the use of KSS containing boron is suspected of the possible formation of glossy spots on the linear guide.

• If the boron content in the KSS used is> 0.3%, you must check whether the product can be replaced with a product with a lower boron content. Please consult the KSS manufacturer for this.
• If you cannot avoid using KSS with boron content > 0.3%, we recommend that you refer to your documented field experience.

Please ask the KSS supplier to confirm that he has experience in using KSS with confidence on the machine. Such experience is, for example, the experience of using this KSS on a machine tool of the same or similar model of our company or on a machine tool with a similar lubrication system.

Our company is not responsible for machine damage caused by excess of the maxi
mum boron concentration of KSS.

The selection and maintenance of KSS is the responsibility of the machine tool operator!

• Attention must be taken to comply with the requirements set out in the chapters “Water-soluble Cooling Lubricant” and “Non-Water Soluble Cooling Lubricant” by our company.
• KSS must comply with the law and the latest regulations of the Occupational Insurance Federation. In addition, local legal regulations must be observed (in Germany, for example, the Technical Guidelines for Hazardous Goods TRGS 611, the Hazardous Goods Regulation, the Biological Materials Regulation, the Industrial Safety Regulation and BGR 143).
• Please ask the KSS supplier to confirm in writing that the KSS used meets the regulations in terms of concentration! Important factors in ensuring production quality and environmental protection are mainly:
• The content of mineral oil and synthetic oil.
• Water hazard level.
• Additives added.
• It is suitable for all processing methods and the necessary commonality of materials.
• does not hurt the skin.
• KSS should be environmentally friendly and harmless to the workplace.

The selection and maintenance of KSS is the responsibility of the machine tool operator!

The selection and maintenance of KSS is the responsibility of the machine tool operator!

The selection and maintenance of KSS is the responsibility of the machine tool operator!

The selection criteria for KSS are only physical chemistry as well as microbiology guidelines and properties. Therefore, there is no need to consider how to determine the product.

Inapplicable or inadequately tested KSS.

Components and parts that come into contact with KSS can be damaged, such as the supply pump and seals.

Only after long-term testing can the new KSS be approved.

Our company does not assume any responsibility for machine tool damage and functional limitations caused by machine tool operators during processing.

This includes, in particular, the following cases:

• Use of inappropriate KSS.
• Insufficient or incorrect maintenance of KSS.
• Use of inappropriate blended water.
• In case of problems, please contact the KSS supplier.

4.6.2 Water-mixed cooling lubricant

4.6.2.1 Specification on cooling lubricant

It should be noted that only cooling lubricants that meet and fit the requirements listed in this table can be used, and the cooling lubricant must be able to flow through a filter device with a 25 µm filter. This limit is suitable for application concentrations.

Serial number	Parameters/detection methods	Restrictions	Unit of measurement
1	Anti-corrosion: Ash cast iron chip filter testing including additional extensions.	There was no corrosion after 2 hours. No corrosion after 12 hours. No corrosion after 24 hours.	Score 0 Score 0 Score 0
2	Paint compatibility: grid cutting inspection, round mandrel bending inspection	No erosion of paint. No cracks at 45°C.	coefficient 0... 1
3	Elastomer (synthetic rubber) compatibility	Maximum change in Shore hardness A +/- 10%, maximum +/- 10% dip, or shrinkage.
4	Microbial stability.	According to product technical requirements and manufacturer's regulations.	Side notes
5	Non ferrous metal compatibility	Do not corrode copper, brass and aluminum parts, mainly in discoloration and the formation of corroded surfaces.
6	The viscous residue characteristics after being concentrated by slow evaporation at 70°C.	Non bonding! Slight residual solubility or re-emulsification.
7	Foam characteristics: The rotating speed is 20000 1/min. Test tube disperser with air inlet.	The 500 ml beaker did not overflow.

Explanation of numbering.

• Corrosion protection characteristics are tested in accordance with the gray cast iron chip testing of the German Standard DIN 51360 Part 2. In this German Standard DIN-method, it is expected that the reading will be taken after one hour. If there is a deviation from this, the filter paper should be evaluated after 1 hour and 12 or 24 hours. The evaluation criteria are based on the German Standard DIN 51360 Part 2.
• Cooling lubricants should be exposed to a temperature of 50°C for 14 days without damaging their coating characteristics when inspecting grid scratches in accordance with the German Standard DIN EN ISO2409. In addition, the Brinell indentation hardness of paint (DIN EN ISO 2815) should not change negatively. According to the German Standard DIN EN ISO1519 in the round bar bending test (2 mm), a sheet with a coating of 0.7 mm should not be cracked when it is bent to 45°C.
• According to German Standard DIN 53505, the value of Shore hardness A is allowed to change by +/-10% at the maximum. According to German Standard DIN ISO 23529, the maximum permissible change in straight line size is +/-5%. (14 days of operation at 50°C)
• Analysis, conservation measures and the addition of maintenance chemicals are often uneconomical when machining machines come with their own supply of cooling lubricants, so cooling lubricants used for this type of equipment should show proper basic configuration and stability from the beginning. For example, it can be confirmed by cycle testing. To assess the stability of microorganisms should be used DIP Slides (Infringent Agar Tablets) (see www.bode-chemie.com - "bode_dip_slides.pdf" for this).
• Use the German Cooling Lubricant Federation VKIS No. 7 work page to test (determine the corrosive effect of water-mixed products on copper; please refer to the website www.vkis.org) to evaluate electrolytic copper, brass or aluminum strip samples The surface of non-ferrous metals is quantitatively evaluated. Cooling lubricants should contain non-ferrous metal corrosion inhibitors.
• Refer to the German Cooling Lubricant Federation VKIS No. 9 work page for this test (evaluate cooling lubricant (tank bottom) deposits and check residual solubility). In this test, the mixture of 20g of 5% (weight percent) cooling lubricant and user's water is evaporated and concentrated. The adhesive properties will be described in three states, (1) "bonded" (pulling out the filament), "fixed" (paint-like film), or "non-bonded". The bonding effect should be as weak as possible. Please note that too strong bonding effect can negatively affect machine function, especially during prolonged machine outage.
• Add 300 ml of cooling lubricant to a 500 ml beaker. No liquid should overflow after 60 seconds of mixing. The test is suitable for determining the trend of forming foams and comparing the stability of the cooling lubricant foam. A “soda effect” can be obtained in an extended detection (determining trends by bubble bursting). Cooling lubricants with inadequate foam properties or cooling lubricants - working solvents can be easily identified.

If an individual limit value is exceeded during the described test, we recommend to consult with the cooling lubricant supplier, because in many cases one countermeasure is sufficient to solve the problem and can thus avoid the replacement of the entire cooling lubricant.

2.6.2.2 Technical parameters of mixed water

In addition the valid regulations and limits of the local water resources government administration should be observed.

Serial number	Parameter	Restrictions	Unit of measurement
1	Total hardness	5 - 20 Recommended 8 - 12 (0,9-3,6)	°DH (German Hardness) (mMOL)
2	PH-value	7 +/- 1	pH
3	Conductivity	Max 700	US (Mikro Siemens)
4	chloride	Max 30	ppm
5	Bacteria breeding	10²	KBE

Explanation of numbering.

• Please clarify the best water conditions with the cooling lubricant-supplier, and take corresponding measures according to the actual situation. When there is deviation, saponification may be caused by too hard water or foam may be formed when water is too soft. Please have cooling lubricants suppliers confirm these limits in writing.
• In the event of deviations, please be sure to negotiate with the cooling lubricant supplier about the possibility of water preparation and implement the required measures.
• If the conductivity of the formulated water is already above standard, there is an increased risk of corrosion. Appropriate preparations for water treatment must be taken.
• When the chlorine content is higher, there is a greater risk of corrosion, so it is necessary to properly prepare water.
• The mixed water should show drinking water quality, otherwise it will increase the risk of microbial invasion and corrosion. Problems often arise due to improperly maintained water preparation treatment equipment. Please consult with the cooling lubricant supplier on this.

4.6.2.3 Mixing of cooling lubricants

Please note the description of corrosion prevention in the manufacturer's product data page. The recommended concentration must be followed.

In order to make emulsions, a stirring mixer should be used. In all cases, only slowly mix the cooling lubricant-concentrate with the mixing water.

The cooling lubricant is mixed incorrectly.

Property damage due to corrosion of parts and components in contact with cooling lubricants, e.g. damage to cooling lubricant equipment and chip conveyor containers.

• Only allow the machine's cooling lubricant equipment to be injected with a mixed emulsifier.
• Note that pure water is not allowed, otherwise it will be below the minimum concentration. (In accordance with the technical specifications in the section "Technical Parameters of Mixed Mixed Water")
• The emulsifier can only be kept in suitable containers. Contact the manufacturer if necessary.

Attention should be paid to the mixing temperature.

The temperature difference between the concentrated cooling lubricant and the adhesion water during mixing is not allowed to exceed 10K. The minimum temperature of concentrated cooling lubricant and adhering water is 10°C, and the maximum temperature during mixing must not exceed 30°C.

4.6.2.4  Supplemental addition and replacement of cooling lubricant

The correct concentration of coolant lubricant should be added in a timely manner if necessary.

In this regard, it is essential to determine the emulsion concentration in the machine cooling lubricant circuit. Monitoring once a day will prevent undetected changes in concentration.

Please note that the concentration composition may change through vaporization and loss with the workpiece.

As the use time increases, the technical characteristics of the application of cooling lubricants will also change. This is also known as aging. If appropriate measures (for example, the use of calibrators) cannot stop this Process, partial or complete replacement is necessary. Please consult with the cooling lubricant supplier.

Suggestions for cleaning

Please note that machines that are not thoroughly cleaned will greatly reduce the life of cooling lubricants (e.g., via contaminants or flora generation) after the new injection.

24 hours before the planned replacement, add 1-2% system decontaminant to the old cooling lubricant (please consult with the cooling lubricant supplier for details). In order to reach all contaminated areas, the highest liquid level that meets the operational requirements must be generated in the machine tool. To make the system purifiers evenly distributed, continue to run the machine tools or let the cooling lubricants operate in a circulating flow manner. The emulsifier is discharged after about 24 hours and thoroughly clean the processing area, chip conveyor and cooling lubricant unit. Therefore, flush the machine tool at the same filling volume with circulating diluted cooling lubricant (about 1%), such as flushing with a system decontaminant. The residual amount of preservative and dissolved contaminants should be removed while maintaining the system decontaminant.

System Cleaner

Wrong system purifier.

Property damage is caused by corrosion of parts and components exposed to the purifier, such as the housing of cooling lubricant equipment and chip conveyor.

Do not use pure water for cleaning.

Please use the system purge agent determined by the cooling lubricant and pay attention to its application regulations. Please also consult with the cooling lubricant supplier on this.

Cleaning effect:

The selected system purifier should stay in the cooling lubricant system for about 24 hours and then follow the recommended concentration. The cleaning effect should be obvious.

This system purifier is not a substitute for mechanical cleaning in case of severe contamination of machine tools and cooling lubricant systems!

New addition of cooling lubricant

Always fill the machine with diluted cooling lubricant (approx. 1%) before filling with cooling lubricant and flush for at least one hour; otherwise there is a risk of shortened life and/or foam formation during subsequent re-use.

Waste disposal

 

Recycling and disposal of used cooling lubricants according to local regulations! The safety data page for cooling lubricants contains relevant precautions.

4.6.2.5  Monitoring and documentation

In order to ensure the function of the machine/equipment, the cooling lubricant must be periodically tested.

Our company suggests that the number of inspections should be determined together with the cooling lubricant supplier, because the number of inspections is greatly affected by environmental conditions and processing tasks.

If the user's company does not have the necessary test equipment, the test can only be carried out by an independent test laboratory or by the cooling lubricant supplier.

This test result must be archived and given to the after-sales technician of our company upon request. (See TRGS 611)

Parameter	Parameter	Measuring method/measuring agent	Cycle (standard)	Scheduled
1	Concentration	Refractive Checker	Once a day	According to the manufacturer's instructions.
2	PH-value	A combination test paper with 0.2- as a block in the important range.	Once a week	The pH-value range recommended by the cooling lubricant manufacturer.
3	Nitrite	Combination test paper 0 - 80 ppm.	Once a week	For example, up to 20 ppm (used in Germany).
4	Chloride	Max 100	once a month	ppm
5	Total hardness	Combined test paper 0 - 30°DHC.	once a month	Min 7°dH to Max 30°dH

8	Temperature	Thermometer	Once a week	Max 35C
9	Conductivity	Measuring electrode	Once a week	Up to 4000µS

Explanation of numbering.

• The manufacturer of the cooling lubricant has given the required concentration for use. There must be emphasis on never allowing conditions below or above that tolerance limit, otherwise there will be other corrosion hazards. Please note that in general the level should not fall below the minimum level (see chapter "Maintenance").
• If the limit values specified by the cooling lubricant supplier are exceeded or lowered, it is important to discuss suitable stabilization measures with the cooling lubricant supplier.
• If the specified limit value (currently 20 ppm is used in Germany) is exceeded, there are the following possibilities to solve the problem:
  • Replace part of the cooling lubricant.
  • Replace all cooling lubricants.
  • Detect the content of nitrosamines in cooling lubricants and working gas.
  • Exceptions to TRGS 611 are obtained.
• The total hardness greater than 30°dH (5.4 mMoL) can lead to stability and corrosion problems. Total hardness below 7°dH (1.25 mMoL) will often trigger foam problems. Please contact the supplier of the cooling lubricant and give the deviating values in writing if necessary, or ask the supplier to recommend another cooling lubricant.
• Fungal growth in cooling lubricants can be related to corrosion problems, foaming problems, or even major problems. Therefore, the presence of impermissible enzyme bacteria contamination in the system is not allowed. It is important to detect areas where enzyme bacteria can easily grow, such as the four walls of the vessel, piping, cooling lubricant pumps and filter unit dispensers/inlet plates. When slimy moss appears in these areas, there is a major suspicion of fungus production. Unfortunately, since the introduction of an intrusive medium (Dip-Slides) is not particularly convincing for the presence of fungi, additional visual examination is essential. In the big cooling lubricant - the system adopts preventive antiseptic treatment is economical. The fungicide content should be monitored regularly (at least 14 days) using laboratory technology and cooling lubricant should be added when necessary. Such analysis tests should be carried out by the cooling lubricant manufacturer or a neutral testing organization.
• It is important to note that there are also slow-growing colonies and anaerobic bacteria, which are not recognized with traditional immersion cultures. A pilot analysis is provided here for a large cooling lubricant system, after which the biocide content is determined and specified, what amounts have been consumed and how much additional is to be added. These analysis tests should be carried out by the manufacturer or a neutral testing organization.
• If the temperature in the cooling lubricant tank exceeds 35°C, we recommend controlling the temperature of the cooling lubricant.
• Corrosion problems may occur when predetermined values are exceeded and cause the emulsion to break down into water and concentrate. When the above temperature is exceeded, please consult with the cooling lubricant supplier in time.

4.6.2.6 Help with problems

Corrosion of machines, tools and workpieces

Possible Causes	Troubleshooting
Condensate formation	Machine tool ventilation change (open the machining area door and operating door).
Since there is a foreign body PH-value will drop.	Please check the pH-value, add a pH-value-stabilizer if necessary; prevent foreign matter (such as oil, germs) from being invaded.
Reduce cooling lubricant concentration.	Please check the concentration and increase the concentration if necessary. Please use a stirring mixer, please pay attention to complying with the mixing rules.
Increase hardness, or increase salt content.	The total hardness of the cooling lubricant should be tested, and if necessary, use VE-water* to resist.

Please check the filtration (hydrocyclones must not be used.)
Mis-tuned centrifuges will lead to cooling lubricant - deprivation of components.	Match the adjustment if necessary.
Cooling lubricant supply is insufficient.	The pump power and nozzle debugging shall be checked.
Reduced lubrication performance by foam.	See the section on bubble issues.

Cooling lubricant (bottom of the tank) deposits on the machine tool

Possible Causes	Troubleshooting
Foreign oil (poor rinse characteristics, adhesion).	Appropriate maintenance devices should be used, such as an oil skimmer or a contaminant oil separator for removing the closed oil cap. foreign oil compatibility test, Partially replace the cooling lubricant if necessary.
Increase hardness, or increase salt content.	Please check the total hardness of the cooling lubricant, and if necessary, use technical conditioning to neutralize it.

Foam formation

Possible Causes	Troubleshooting
The total hardness of the emulsion is too low.	Please consult with cooling lubricant supplier to increase the hardness of the coolant lubricant if possible.
Contamination by foreign substances (e.g., cleaning agents).	Partially replace (at least 50%) the cooling lubricant.
The cooling lubricant concentration is too high.	Reduce the concentration of emulsion with the right water quality.
Unsealing (pump) in the circulation loop.	Causes of failure that should be eliminated.

Filtering problems

Possible Causes	Troubleshooting
Mold infestation	Mechanical cleaning. After consultation with the cooling lubricant manufacturer, the appropriate fungus should be used, and it is important to adhere to the prescribed dosage.

4.6.3 Non-aqueous hybrid cooling lubricant

4.6.3.1 Specification of cooling lubricant

Warning! Material with a risk of explosion!

When combustible oil is used as a cooling lubricant, explosive cooling lubricant-vapor-aerosol-air mixtures may be generated in the machining room of the machine tool.

Injury accidents may occur through fire, explosion or spark deflagration, and may result in death or serious personal injury.

• In the absence of special fire fighting equipment. For safety reasons (explosion hazard), cooling lubricants (cutting oils) that cannot be mixed with water are not allowed.
• When processing is used, it must have, and the monitoring system of the fire extinguishing device must be activated.

Only use cooling lubricants with the following characteristics:

1	Paint compatibility: grid cutting inspection, round mandrel bending inspection	No erosion of paint. No cracks at 45°C.	coefficient 0... 1
2	For compatibility of elastomers (synthetic rubber), please refer to paint inspection for explosive conditions.	Maximum change in Shore hardness A +/- 10%, maximum +/- 10% dip, or shrinkage.
3	Non ferrous metal compatibility	Non-ferrous metals that are discolored due to erosion and form films are not allowed.	Index 1 (only for copper)

Explanation of numbering.

• The cooling lubricant should be exposed to 50°C for 14 days. A grid cut test in accordance with the standard DIN EN ISO 2409 shows that the properties of the coating have not deteriorated. In addition, the Brinell indentation hardness of paint (DIN EN ISO 2815) should not change negatively. According to the German Standard DIN EN ISO 1519 in the round bar bending test (2 mm), a sheet with a coating of 0.7 mm should not be cracked when bent to 45°C.
• According to German Standard DIN 53505, the maximum allowable change in Shore hardness A value is +/-10%. According to German Standard DIN ISO 23529, the maximum permissible change in straight line size is +/-5%. (14 days of action at 50 °C).
• Copper-corrosion test according to Standard DIN EN ISO 2160.

4.6.3.2 Provisions on processing and machine tools

Blunt, broken blade or wrong rapid cooling.

Coolant lubricant combustion hazards due to fog on the blade or the formation of sparks.

• Adjusts the coolant lubricant nozzle to optimum condition to rinse the processing area and avoid chip build-up.
• A sufficient amount of cooling lubricant should be supplied to prevent sparks from forming on the blade.
• Cooling lubricant supply must be monitored.
• The temperature of the cooling lubricant must also be monitored.
• Suction devices suitable for oil processing (electrostatic) must be installed.
• Blunt and non-fogging oil should be used (see the recommendations of the Industrial Injury Insurance Federation on fire and explosion protection).

Explosion-proof kit is needed!

For machine tools that cannot be optimized to the above parameters, an additional explosion-proof package must be installed.

4.6.3.3 Supplemental addition and replacement of cooling lubricant

Added in a timely manner.

Be sure to ask for timely additions.

If the technical characteristics of the cooling lubricant cannot be maintained economically (for example, due to contamination, aging), the cooling lubricant must be replaced. Please consult with the cooling lubricant supplier.

Recording is required when the cooling lubricant is replaced or added. (See the section "Monitoring and Archiving Records")

Suggestions for cleaning

Please note that a machine that is not thoroughly cleaned will shorten the life of the cooling lubricant (for example, in pollution), or may reduce cutting capacity.

Before emptying, the cooling lubricant should be circulated for at least one hour or circulated with a pump to avoid contaminated esters. Pump out the old cooling lubricant directly after this, preferably drawn from the coolant lubricant unit as deep as possible.

New addition of cooling lubricant 

Rinse with new product.

• When the composition is greatly changed after being heavily contaminated or after long-term use, a new product should be used for washing.
• The amount of cooling lubricant used for flushing is then recovered and disposed of.
• The need for such a flush operation can be derived with the help of analytic data.
• If it is contaminated by a large amount of incompatible foreign matter (for example: concentrate, glycol, water, solvent, cleaning agent), if necessary, special measures should be taken to ensure that the foreign matter is completely removed from the circulation system.
• Please consult with the cooling lubricant supplier to avoid damage to the machine tool or performance degradation during cutting.

Waste disposal

Recycling and disposal of used cooling lubricants according to local regulations! The safety data page for cooling lubricants contains relevant precautions.

4.6.3.3 Monitoring and documentation

In order to ensure the function of the machine/equipment, the cooling lubricant must be periodically tested.

Because this is greatly affected by environmental conditions and processing tasks, I recommend working with the cooling lubricant - supplier to determine the frequency of inspections.

When the necessary equipment is not available in the company, this test can be performed by other laboratories or by cooling lubricants - suppliers.

This test result must be archived and given to the after-sales technician of our company upon request.

“Improvement” Description — Continuous improvement of weaknesses in accordance with BVW (Recommendations for cooling lubricant manufacturers). Refer to our table in the Random Offering Log for this.

Serial number	Parameter	Measuring method/measuring agent	Cycle (standard)	Scheduled
1	Viscosity (40°C)	DIN 51562	monthly	According to manufacturer's instructions (mm2/s).
2	Water content	DIN EN ISO 12937	monthly	Increase when compared to the original product <300 ppm 。
3	Phosphorus, sulfur, zinc, calcium, sodium, copper, chlorine	ICP (inductively coupled plasma) or X-ray fluorescence.	This period is determined in consultation with the cooling lubricant supplier.	<20% deviation when compared with the original product.
4	flashpoint	Pan-Marmite Closed-Cup Flash Point Test Method.	When necessary.	>140°C conforms to International Standard ISO 2719

Explanation of numbering.

• When the viscosity changes significantly (+/- 20%), please check whether there is foreign oil from the machine tool or the workpiece. This may have an adverse effect on the filtration and/or processing procedures, for example. Partially replace the cooling lubricant when necessary.
• If that limit is exceeded, then negotiate with cooling lubricant supplier to take appropriate stabilization measures, for example, with the appropriate absorbent treatment or partial replacement. (see Karl-Fischer measurement method)
• When determining the flash points, the decrease of solution odor and/or viscosity implies that there is serious foreign body infestation.

4.6.3.5 Help with problems

4.6.4 Minimum lubrication

Minimum lubrication is the method that uses no more than 50 ml of lubricant on average per processing hour and processing site (BGR 143). When the process is optimized, the minimum amount of lubrication can increase productivity and contribute to environmental protection.

4.6.4.1 Specifications on the cooling lubricant

Minimum amount lubrication system.

Minimum amount lubrication system is allowed in machine tools with non-water mixed cooling lubricants!

Warning! Material with a risk of explosion!

When combustible oil is used as a cooling lubricant, explosive cooling lubricant-vapor-aerosol-air mixtures may be generated in the machining room of the machine tool.

Injury accidents may occur through fire, explosion or spark deflagration, and may result in death or serious personal injury.

• In the absence of special fire fighting equipment. For safety reasons (explosion hazard), cooling lubricants (cutting oils) that cannot be mixed with water are not allowed.
• When processing is used, it must have, and the monitoring system of the fire extinguishing device must be activated.

Only use cooling lubricants with the following characteristics (see BGR 143):

• Flashpoint > 140 ℃ meets International Standard ISO 2719 (Pan-Marmite Closed-Cup Flash Point Test Method).
• Evaporation loss < 5% (according to German Standard DIN 51581-1 at 150 ℃).

• Cooling lubricants marked as meeting hazardous material regulations.
• Mineral crude oil-based products in cooling lubricants contain> 3 ppm benzopyrene.
• Natural esters (rapeseed oil or similar) have a tendency to solidify.
• See BGI 718 for further information.

4.6.4.2 Processing procedures and machine tools

The use of coolant lubricant requires machine tools specially prepared, concerning:

• The air mixing device used to prepare the cooling lubricant.
• The way of conveying the blade.
• Clear the chips.

We are not responsible for machine tool damage caused by machine tool users and performance limitations during processing.

This relates specifically to:

• The cooling lubricant does not meet the cutting parameters.
• The lubrication dosage is incorrect.
• Due to improper processing optimization, problems may occur when removing chips.
• Processing accuracy changes due to insufficient cooling effect of the cooling lubricant.
• If there is a problem, please contact the cooling lubricant supplier.

Determine the ability of machining door window glass to block impact

The viewing glass in the processing area that is not damaged on the outside bears the following loads:

• cooling lubricant
• cleansers
• tallow
• oils
• other corrosive media

The aging process will lead to quenching. Therefore, the viewing glass in the processing area is classified as a consumable part. The ability to block impact of window glass in the processing room depends on

• the diameter of tool used.
• speed used.
• aging degree of glass.

The replacement is done through the after-sales service department of our company.

According to the characteristic curve, the blocking performance is determined

As seen in the characteristic curve chart, the maximum allowable tool diameter and maximum permissible speed of an observation glass without damage depends on its aging degree. According to the German Standard DIN EN 12417 there is a potential risk when flying out parts with a mass of 100 g.

The curve chart is suitable for cooling lubricants or other corrosive media.

The service life will be extended by 2 years without taking into account the effect of cooling lubricants or other corrosive media.

The allowed tool speeds follow the instructions of the tool manufacturer, and not according to the theoretical limits in the characteristic curve chart.

Tool and speed allowed for 12 mm polycarbonate glass.

1. 4 years old                 2. 6 years old                 3. 8 years old

4.Maximum spindle speed [1/min]                  5. Maximum tool diameter [mm]

For example: when viewing glass is used for 6 years, the theoretical permissible speed of a 150 mm diameter tool is 10000 1/min.
