在车削加工铸铁等脆性金属材料时，形成许多颗粒大小不一的崩碎切屑。切屑到处飞溅，不但给机床维护保养以及切屑的清理带来很多麻烦，且对价格昂贵的铜合金切屑，也给回收带来很大困难。为解决上述问题，通过多次试验，设计出一种能够有效地集聚崩碎切屑的新型车刀──机夹集 When machining brittle metal materials such as cast iron, many disintegrating chips of different particle sizes are formed. Chip splatter everywhere, not only to the machine maintenance and cleaning chips brought a lot of trouble, and the expensive copper alloy chip, also brought great difficulties for recycling. In order to solve the above problems, through a series of experiments, we designed a new type of turning tool that can effectively aggregate and disintegrate chips.
