Direct clamping into the work spindle
Tools or collet chucks with a MT2 shank may be clamped directly into the work spindle. For
mounting these tools, proceed as described in ‘inserting tool’ on page 13.
Make sure that the tool is clamped with the draw-in rod.
4.5 Changing the speed range
Wait until the machine has come to a complete halt before
changing the speed using the gear switch.
•
Turn the gear switch in the position ‘H’ for a speed
range of 200 – 3000 min
•
Turn the gear switch into the position ‘L’ for a speed
range of 100 – 1500 min
•
Adjust the speed with the potentiometer
Selecting the speed
For milling operations, the essential factor is the selection of the correct speed. The speed
determines the cutting speed of the cutting edges which cut the material. By selecting the
correct cutting speed, the service life of the tool is increased and the working result is optimized.
The optimum cutting speed mainly depends on the material and on the material of the tool. With
tools (milling cutters) made of hard metal or ceramic insert it is possible to work with higher
speeds than with tools made of high-alloy high speed steel (HSS). You will achieve the correct
cutting speed by selecting the correct speed.
For the correct cutting speed for your tool and for the material to be cut you may refer to the
following standard values or a table reference book.
The required speed is calculated as follows:
