1. Machining non-continuous surfaces can lead to intermittent cutting, such as when machining various grooves and clearing roots. In classic turning operations, this operation can generate unfavorable shock loads, resulting in poor machined surfaces and premature tool wear. In the turning and milling compound machining, the tool used is a milling cutter, and the milling itself is intermittent cutting when the load changes periodically.
2. When the processed material is a long chip material. According to the analysis of CNC turning and milling composite processing manufacturers, chip formation is difficult to deal with in turning processing; finding a suitable chip breaker for turning tools is not an easy task. Mill-turn milling cutters produce short chips, which significantly improves chip control.
3. Analysis of CNC turning and milling composite processing manufacturers, taking the processing of crankshafts and spindles with eccentric journals as an example, in turning processing, the eccentric mass of workpieces such as crank journals, eccentric cams, etc. adverse effects, which are avoided in turn-mill due to the low rotational speed of the workpiece
