3.1 Basic notes
It refers the danger that may cause an accident to operators.
The rotational speed of the tool used shall be allowed by its manufacture.
The spindle can be started only after the tool is well clamped.
The use of a suitable combination of the tool and the toolholder required the tool to have a very small runout value.
The bearing surface of the tool shall be clean.
The rotational speed limit achieved by meeting cutting process parameters such as “allowable cutting speed” shall be valued!
Only the predetermined shank and rivets is used.
Shank and rivets are only used when it is suitable for cooled lubricant pressure.
Only the same tool type as the working spindle is allowed.
May cause damage to the working spindle if you neglect of these !
3.2 Tool HSK 63A
3.2.1 Tool with taper shank (HSK) equipped by internally cooled lubricant
Refer to Chapter “Technical Parameters” only when the predetermined shank is used.
Shank is only used when it is suitable for cooled lubricant pressure.
The pressure of cooled lubricant in the tool system is high.
Rinse-off of the lubricant film causes clamping pressure loss and broken clamping jaw.
Tool with internally cooled shank (HSK) shall be equipped with internally cooled lubricant tube (1)(scope of supply of tool manufacturers shall be noted).
Mechanical damage is not allowed on cooled lubricant tubes; lead-in chamfer used for the sealing element shall be equipped on clamp-on taper shank.
A non-sealing condition between the shank and cooled lubricant tube shall be cleared, or the tool will not allowedto use.
Cooled lubricant tube

As an option,we also provide SK 40 tools
Stud for shank SK 40 DIN 69871-1:
Nails with or without annular grooves according to DIN 69872:
Type A: with through-hole for central coolant supply.
Type B: Used to supply coolant from the side through the tool connecting disc.
3.3.2 Shank size
1 Single cutting edge, cutting edge position 3 A or B type2 Align with washer 27.065 920
3.4 Allowable vibration caused by unbalance while cutting
Vibration caused by out-of-roundness of the rotating tool.
Property loss and personnel injury may be caused by tool breaking and flying
workpiece with great kinetic energy.
Cleanliness of tool and bearing surface of machining spindle shall be noted during tool changing.
Allowable radial and side face runout value shall not be exceeded.

3.5.2 Limit size of tool for automatic tool change
When the tool with diameter greater than 130 mm and weight less than 6kg shall be used because of process technology, manual tool change must be adopted in consideration of balance precision.
The user shall be responsible for using tool with weight heavier than 6kg and diameter greater than 130mm.
3.6 Calculate allowable rotational speed
In addition to rotational speed limit within limit speed of spindle/tool system, rotational speed limit that meets cutting process data such as allowable cutting speed shall also be valued.
For the tool used, its rotational speed shall be permitted by the tool manufacturer.
3.6.1 Spindle with high rotational speed
Using tool with greater diameter or higher rotational speed may cause accident hazard!

3.7 Tool Magazine
3.7.1 Description of tool magazine
The tool can be loaded in and unloaded from the magazine not only manually through hand-operated door at the top of the magazine, but also through the spindle.
The magazine is connected to machining space through automatic door of magazine. When the door closes, the space between them is isolated. Automatic loading tool movement between spindle and tool is achieved by tool changing-manipulator.
The passage to magazine is monitored by photoelectric switch.
Magazine can be manually operated only in a state of JOG.
Machine program can be operated only when the magazine door closes. Please confirm that no one is within the tool magazine when machine tool is operated and after maintenance.

3.7.2.2 Tool loading
Loading, used for plugging tool within the buffer in magazine or spindle manually.
Load program appears only when selected tool path or spindle is vacant.
Prerequisites
Be sure to align down the guide gib (German angle projection).
The blade is sharp, so there is a risk of injury if toughing the blade.
Please wear safety gloves.
Don’t clamp the tool within the range of synchro flange.
Installing backwards of plugging dislocation may damage the magazine or spindle during tool changing; be sure to check carefully after the tool is plugged.
- When closing the tool magazine, the door lock will block automatically.
- A mechanical drop-proof mechanism keeps tools in the tool cylinder.
