本文向大家介绍一种用修整螺距来补偿热处理轴向变形的办法,它可以解决滚珠丝杠在制造过程中由于热处理轴向变形造成大量废品的问题。 1、滚珠丝杠在制造过程中存在的问题滚珠丝杠螺旋槽的R型面要经过表面渗碳硬化处理,因为热处理后产生变形,因而进行机械加工时切削余量不能太大,否则将把最佳表面层(过共析层)去掉,使表面硬度下降到丝杠不能使用的程度。
This article introduces a way to compensate for the axial deformation of the heat treatment with the trim pitch, which can solve the problem of a large number of waste due to the axial deformation of the ball screw in the manufacturing process due to heat treatment. 1, the ball screw in the manufacturing process problems Ball screw spiral groove R-type surface to be hardened by surface hardening, deformation after heat treatment, so cutting machining allowance can not be too large, otherwise it will put The best surface layer (over-eutectoid) removed, so that the surface hardness dropped to the extent that the screw can not be used.
