单体铸造的活塞环,在金工加工的头道工序中,大多是先车削两平面。由于各厂的工艺规程不同,有用单刀单面切削的,亦有用双刀两面同时进行加工的。两者各有它们的优缺点。因为这两种加工方法都需要有工艺装备,因此它们就随着工具灵活性的不同而产生了优劣现象。 Piston ring casting monomer, the first process in the metalworking process, mostly turning the first two planes. Due to the different plant processes, useful single-sided single-sided cutting, but also useful both sides of the pole at the same time processing. Both have their own advantages and disadvantages. Because both processes require process equipment, they create advantages and disadvantages depending on the tool’s flexibility.
