11.1 Dividing apparatus
Two different dividing apparatus are available:
Type 1 for collet chuck W25/W20
Type 2 for collet chuck 355E
With the assistance of a reducing sleeve and a special connecting rod, the collet chuck
W20 can also be used in the dividing apparatus type 1.
Figure 11-1: Dividing apparatus
The dividing apparatus can be shifted on the swivel holder in axial direction. The roughly
adjustable stopper A serves for pre-positioning. Fine adjustments can be carried out using
the integrated micrometer screw B. The micrometer screw B has a scale of 0.02mm. One
revolution of the micrometer screw results in a position change of 0.5mm.

Adjusting the dividing scale:
The dividing scale D is clamped by means of the hand nut C. With this, e. g. the zero
marking can be quickly brought to the desired position. The dividing scale is graduated
from 0 degree up to 360 degrees. One graduation mark represents 2 degrees. The
dividing apparatus can be mechanically locked every 30 degrees. For this purpose, a
locking bolt E is mounted on the side.
