Parting off
Y-axis parting is a completely new way of parting-off. In conventional parting off, most of the cutting force is generated by the cutting speed, the rest by the cutting feed. The resulting force is directed approximately 30 degrees into the tool. Thereby, the parting-off blades are loaded in their second weakest direction.
