Respectively for rough finishing. In addition, it is also necessary to pay attention to the intersection of the center line of the tool tip rotation and harmonic CCF-8-30-1U workpiece center line should be in the rotary plane of the tool tip, otherwise, the offset center is too large, intermittent turning will occur and the workpiece will be discarded. The workpiece cannot rotate during the cutting process. This method is generally only suitable for machining elliptical axes with short elliptical axes below 80~ 80.



In turning, reverse cutting is a more efficient cutting method. It can make the radial cutting force and machine tool spindle, harmonic rotary table harmonic CSF-8-30-1U fixture and workpiece gravity consistent, effectively avoid and eliminate the spindle bearing clearance caused by the self-excited vibration, in large diameter cutting, effectively make the chip and gravity direction consistent, make chip smooth. Therefore, it is also the method often used in turning
