Internal Inspection

After 10 years 1)

Emphasized Inspection

After 10 years 1)

Regular inspection time

The machine tool user determines the time of the regular inspection based on the results of previous regular inspections and experience with dosing and operating conditions in accordance with Section 2, Article 10 of the Pressure Vessel Regulations. At this point, the user can rely on the recommendations of the manufacturer and experts, or on the relevant experience of professional and technical personnel inside and outside the enterprise, especially in the case of mass-produced equipment.

Carry out the inspection of pressure accumulators in all EU countries in accordance with local laws and regulations.

1.2.4 Thermal operation of spindle

Due to the unstable thermal state, no clamping of the working spindle, including the spindle bearing, this spindle must be operated in a thermal state after the downtime specified by the machine manufacturer. During this period, no high-speed processing is allowed. This measure can protect the machine tool and thus extends the spindle bearing life. Spindle standstill time should be collected in real time. If the 2-hour limit time set by the manufacturer is exceeded, the spindle will run in thermal state after the spindle is powered up and an alarm message will be issued indicating SPINDELWARMLAUF AKTIV (spindle thermal operation is valid).

Attention must be paid:

  • Here, the spindle speed should be reduced to half of the possible maximum speed of the motor-driven spindle
  • The operator must ensure that a suitable tool is available on the machining spindle.
  • If a tool is installed on the spindle, SPINDELWARMLAUF NICHT MÖGLICH (thermal operation of the spindle is not possible) is displayed.
  • The alarm message SPINDELWARMLAUF AKTIV (spindle thermal operation valid) and feed blockage appear during spindle thermal operation. The alarm message is automatically deleted and the feed is allowed after reaching approximately 3 minutes of thermal operation.
  • The speed will be automatically limited if the programmed speed exceeds the specified limit value.
  • The user can make the thermal operation of axis in fast forward G0 and that of the spindle with the allowable maximum speed after changing tool.
  •  Operation No feed forbidden will be triggered during the process of G0 fast shift and this speed will be automatically reduced.

Monitoring of spindle warm-up operation can be canceled at the request of the user.

It should be recorded if the spindle thermal operation is not activated.

1.2.5 Description of the continuous operation of the axis

1.2.5.1 Circular axis in CNC-Rotary table

The circular axis in the CNC-Rotary Table on the machine tool is designed to be inserted into the running positioning axis within the lower limit of the speed. Circular axis is not suitable for continuous operation at maximum speed or the upper limit of the speed.

Continuous operation may cause the CNC-rotary table to heat up and consequently cause geometrical changes. Related to this, the machine tool accuracy has to be taken into account.

  • In this sense, these instructions apply to all table variants and indexers with circular axes.
  • These instructions do not apply to CNC-Milling/Turning tables.

1.2.5.2 Work spindles and linear axis

The continuous operation of the highest speed work spindle and the maximum acceleration linear axis may cause the machine tool components and the entire machine tool to heat up and geometric changes may occur as a result. Related to this, machine tool accuracy must also be taken into account.

1.3 In the production process

All basic instructions for production.

1.3.1 Notes for processing accuracy

The following notes are based on the given conditions and experience regarding the influence of temperature on the workpiece, tool and machine tool. Whether these notes are taken seriously or not has a direct impact on the achievement of machine accuracy. The problems arise in process within a small accuracy scope helps to discover other influencing factors.

1.3.1.1 Temperature

The smaller the temperature difference (difference between ambient temperature and initial temperature) when processing a workpiece, the smaller the variation in the machine, tool and workpiece. The best way to obtain high precision processing is to keep the ambient temperature as constant as possible.

The following temperature values must be maintained at the location where the machine tool is positioned:

  • In order to achieve the guaranteed accuracy, the temperature change must not exceed 0.5 K per hour and 2 K per day.
  • The temperature change in space must not exceed 0.4 K/m3.

1.3.1.2 Location

If the machine tool is located at the entrance area of the workshop and exchanges air with the outside when opening and closing the door, there will certainly be corresponding fluctuations in ambient temperature that adversely affect the processing results. If this happens when the door of the processing area is open, there will be significant fluctuations in the temperature of the workpiece and the work spindle.

1.3.1.3 Warming up the machine tool

The friction of the bearings mainly causes the work spindle to heat up and contributes to a constant temperature. If a constant temperature is achieved by warming up the machine tool before starting processing, only small temperature fluctuations will occur during processing.

1.3.1.4 Tool temperature

If a sharp tapered cold tool is replaced into an already warm work spindle, the cold tool will be inserted deeper than the warm tool due to the change in temperature of the work spindle tool holder. It is also important to note this when working with a probe when the machine tool has been warmed up. If the tool holder is equipped with an end face, this effect does not occur.

1.3.1.5 Oil mist/ emulsion mist separator

Equipped depending on machine tool configuration。

Evaporative heat absorption will occur after the separator and the cooling lubricant supply device are connected.

The evaporative heat absorption adversely affects the processing accuracy of the machine tool.

1.3.2 Acceptance of existing components

1.3.2.1 Processing procedures

Utilizing existing procedures.

Damage caused by corrosion.

  • It should be checked whether the procedure is suitable for this machine tool.
  • Attention should be paid to the programming functions, processing period and processing room size in accordance with this manual.
  • In the absence of material, the first program is run by reducing the operation action.
  • Contact your suppliers if you have questions

1.3.2.2 Equipment

Utilizing existing equipment.

The damage is caused because the processing room is too small or is altered.

  • It should be checked whether the device can be used unconditionally or whether software adjustment is required.
  • In the absence of material, the first program is run by reducing the operation action.
  • Contact your suppliers if you have questions.

1.3.3 Collision

1.3.3.1 In the warranty period

Contact the after-sales service department of our company when the machine collides in the warranty period.

The effect of the quality warranty may be affected if not taken care of.

The following data must be saved:

  • CNC-Program:
    • Imported program,
    •  Subroutines 
  • Tool parameters.
  • Zero drift.
  • A tool management device is possibly needed.
  • Parameters are possibly needed.
  • Recording data as an archive.

Additional requested information

  • The machine tool and
    • the whole screen,
    • the machine tool,
    • current collision position,
    • processing room,
    • adapter position of the tool magazine (if installed),
    • workpiece pallet changer (if installed).

Data Transmission

The data and information listed above should be sent to the after-sales service department of our company.

1.3.3.2 Temperature balance compensation for machine tool

CNC-CNC temperature balance compensation is based on the collection of the tool displacement at a given speed over a certain time course. Temperature compensation is mainly used to balance the displacement of the machining spindle after it has been heated.

1.3.4 Reminder: please note in short reciprocating stroke processing

Constant processing reciprocating stroke < 150 mm

In this case, a tool change or programming (the entire stroke of the relevant axis is lubricated) is performed after a maximum of 30 minutes.

Constant processing reciprocating stroke < 10 mm

In this case, a tool change or programming (the entire stroke of the relevant axis is lubricated) is performed after a maximum of 5 minutes.

Constant processing reciprocating stroke < 2 mm

In this case, the machine tool must be equipped with a special structure, that is, the "coated bearing" for the screw rod.

Machine tools with standard configuration are not suitable for short reciprocating stroke process when it is less than 2 mm. This type of process does not fall within the scope of using the machine as specified.

Explanation:

The so-called short reciprocating stroke refers to the reciprocating oscillating axis movement, when the axis reciprocating is very short, so that a single or multiple ball in the machine tool components (feed bearings, ball screws, linear rolling units) cannot be lubricated floatly by the lubrication material, and resulting the loss of (the formation of oil film) oil supply.

If this short stroke dwell time is long, this can lead to a complete exhaustion of the lubricant film between the rollers and the track. In this case, it can lead to direct contact between the ball and raceway (steel to steel), with the consequence of contact wear. The balls and/or raceways will be damaged. This should be avoided in all cases.
