14.1 Grinding the cutter
Halving the cutter:
At first set the graduated scale to 0 degrees. Then clamp the cutter and align it ny means
of the centering bracket. Set both turning angle scales to 0 degrees, set the stoppers and
clamp them against a rotary movement. Set the clearance angle scale to 0 degree. Bring
the cross table of the swivel holder into the central position (the surface must be flush) so
that the rotary axes of the dividing apparatus and the swivel holder intersect.
Figure 14-1: Halving the cutter
Set the dividing apparatus to 90 degrees. Make the contact to the grinding wheel. Adjust
the stopper for maximum insertion depth and start the grinding process with fine infeed.
By moving the swivel holder back and forth, material is removed by the grinding wheel.
Continue fine infeed until the cutter has been halved.
