avoid inflammation. Tool angles recommended cutting speeds for single-lip cutters Centering the Cutter Lip by Grinding Cylindrical single-lip milling cutters are supplied by the manufacturer with the lip preformed by rough milling (see Fig. 1). As a result, the cutter lip will first have to be accurately centered by grinding. Rough grinding of the lip is performed manually by holding the cutter giants the circumference of the grinding wheel (see Fig.2). -

Grinding the Back Rake Angle While continuously rotating the collets bearing through 180 (back and forth between the stops), advance the cutter towards the grinding wheel by means of fine adjustment screw H. This will produce the desired back rake angle on both side and the end cutting edges in a positively controlled operation (see Fig.3, 4, 5). -
