铝铜等有色金属工件,它们的机械特性与钢铁工件不同,不容易达到相应的尺寸精度和表面粗糙度,而且不容易采用磨削方法进一步提高精度和降低表面粗糙度值。如果对铝铜工件的内外圆、端面采用精车留余量,再用压光车刀挤压,则可得到与车削钢铁工件相同 Aluminum and copper and other non-ferrous metal parts, their mechanical properties and steel parts are different, it is not easy to achieve the appropriate dimensional accuracy and surface roughness, and not easy to use grinding methods to further improve the accuracy and reduce the surface roughness value. If the aluminum and copper workpiece inside and outside the circle, the end of fine car leaving the amount of surplus, and then squeeze the pressure car turning tool, you get the same with the turning steel workpiece
