内燃机气门锁夹槽的机械加工光洁度,几何精度达不到图纸要求,是一些生产厂普遍存在的工艺问题。本文介绍的一种滚压精整工艺,经三年来的应用实践证明,效果较为理想。一、原工艺及其存在的问题原工艺采用车床加工,其工作原理如图1所示。其存在问题为: 1.因为是切入进给,刀具主切削刃微观不齐,直接反映到工件被加工表面,影响光洁度。
Internal combustion engine valve lock slot machining finish, geometric accuracy of less than the drawing requirements, is a common problem in some manufacturing plants. This article describes a rolling finishing process, after three years of application proved that the effect is more satisfactory. First, the original technology and its problems The original process using lathe processing, its working principle shown in Figure 1. The existing problems are: 1. Because it is cut into the feed, the main cutting edge of the tool is not micro, directly reflected to the workpiece surface, affecting the finish.
