充分发挥主付刃的切除工件余量的作用,并用付后刀面的熨平点进行挤压熨平已加工表面微观不平度的刀具,通称熨平刀具。它改变了仅仅是企图通过主、付切削刃获得优良加工表面的机理,而与热挤压原理结合,在普通机床上轻易地获得一般加工中难以达到的表面质量。特别值得指出的是对于磨削加工中不易达到高光洁度的软材料如20Cr,A_3等钢材也同样获得优良的表面。
Give full play to the main pay edge of the removal of the role of the workpiece margin, and with the knife after the ironing point squeeze ironing surface roughness of the micro-machined tool, commonly known as screed tool. It has changed the mere attempt to get a good machined surface through the main and the cutting edge combined with the hot extrusion principle to easily obtain the surface quality that is difficult to achieve in normal machining on a common machine. In particular, it is worth pointing out that for soft materials such as 20Cr and A_3, which are hard to reach a high finish in the grinding process, the same excellent surface is also obtained.
