在一般的切削加工中,副后刀面是不起切削和挤压作用的,而在熨平切削中,正是利用副后刀面上的熨平点进行挤压,从而获得高的加工表面质量的一种加工方法。所以熨平切削用的刀具都具有切削作用和挤压作用。滚压和冷挤加工,可以比较容易的获得▽10以上的表面光洁度,这是因为挤压使金属产生塑性变形,金属纤维不仅不会被破坏,而且会使金属纤维细化。熨平切削正是利用了挤 In the general cutting, the Deputy flank can not afford to cut and squeeze, and in the iron cutting, it is the use of sub flank screed on the extrusion, resulting in high processing surface Quality of a processing method. Therefore, iron cutting tools have a cutting effect and extrusion. Rolling and cold extrusion process, you can more easily get ▽ 10 above the surface finish, this is because extrusion plastic deformation of the metal, the metal fibers will not only be destroyed, but also to refine the metal fibers. Iron-cutting is the use of crowded
