1、前言最近,在切削加工领域中,由于数控机床和专用机床的应用,刀具的保养已成为非常重要的问题。为了使刀具在切削加工中经常保持正常工作状态,充分发挥切削效率,需要防止刀具的异常损伤和改善切屑处理性能。刀具的异常损伤和切屑处理性能是随被加工材料、刀具材料和形状、机床、切削条件等因素不同而变化的。本文叙述了刀具的崩刃情况,说明了切削刃的倒棱、刀尖圆弧半径与切屑性能的关系,最后介绍了切削刀具的几种保养实例。2、切削刀具的磨损
1, Introduction Recently, in the field of cutting, due to the application of CNC machine tools and special machine tools, tool maintenance has become a very important issue. In order to keep the tool in the cutting process to maintain normal working conditions, give full play to the cutting efficiency, you need to prevent abnormal damage to the tool and improve chip handling performance. Abnormal damage to the tool and chip handling performance varies depending on the material being processed, the tool material and shape, machine tool, cutting conditions and other factors. This article describes the chipping of the tool, illustrates the chamfer of the cutting edge, the relationship between the radius of the tip and the chip performance, and finally introduces several maintenance examples of the cutting tool. 2, cutting tool wear
