1、序言高速钢滚刀高速滚削时,最值得注意的问题是,滚刀刀齿的崩刃与齿顶圆弧处的异常磨损。随着这种磨损的出现,将相应地产生月牙洼磨损,并使滚刀刃口发生快速破坏,切削负荷加大。切削速度越高,切屑越易卷曲,月牙洼磨损区域就越接近切削刃。因此,当滚刀齿顶圆弧处切下的切屑与切削刃成直角方向排出时,月牙洼磨损的区域离切削刃口较远,为此就需修正滚刀的刀齿形状。本文着重探讨了滚
1, the preface High-speed hob hob high-speed hobbing, the most noteworthy problem is hobbing teeth hobbing edge and addendum arc abnormal wear. With the appearance of this kind of wear and tear, the crater wear will be correspondingly produced, and the cutting edge of the hob will be damaged quickly and the cutting load will increase. The higher the cutting speed, the easier the chip curls, the closer the cutting edge is to the crater area. Therefore, when the chip cut at the tip of the hob at a right angle to the direction of the cutting edge discharge, the crater wear area far away from the cutting edge, the need to amend the cutter hob shape. This article focuses on the roll
