Use of change gears

For automatic longitudinal turning, there are two feeds available with 0.085 and 0.16 mm per
revolution (the wheels are set at the factory for feed with 0.085 mm per revolution).
Fitting various toothed wheel combinations enables metric thread cutting from 0.10-7 mm and imperial
threads with gradients of 10/1"-40/1"
Table for thread cutting
The toothed wheels that belong to the scope of delivery are identified according to the number
of teeth.
e.g. 48 stands for 48 teeth
To thread cut as of a gradient of 0.4 mm, B1 and B2 must be removed completely.
