First, machining discontinuous surfaces can result in interrupted cuts, such as when machining various grooves and root cleaning. 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.
Second, when the material to be machined is a long-chipping 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.
Third, the CNC turning and milling composite processing manufacturers analyze, 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 and eccentric cams can lead to unbalanced forces. machining has a negative impact, which is avoided in turn-mill machining due to the low rotational speed of the workpiece
