提高不锈钢细长轴(管)磨削加工质量的方法

The Way of Improving Chopping and Dawdling Processing Quality of the Thin and Long Stainless Steel Axis(Pipe)

在实际生产过程中,对不锈钢细长轴(管)类零件外圆面应采用车后磨的工艺安排,以保证不锈钢细长轴(管)符合零件的直线度及圆度等要求。但在磨削过程中,易出现变形、烧伤及裂纹等问题,影响零件的加工质量。文中对变型、烧伤及裂纹的形成原因进行了分析并对其消除方法进行了论述,为不锈钢细长轴(管)类零件磨削加工中出现变形、烧伤及裂纹问题提供参考。

In real producing course, for the processing of excircle face of parts shch as the thin and long stainless steel axis （pipe）, we should arrange the operation of lathting first and grindering second to meet the demand of the part＇s straightening and round degrees. But in the couse of lathing and dawdling, the trouble of deformation, empyrosis and crack If parts often appears which affects seriously the processing quality. This paper discusses the cause of these troubles and countermeasures which has directing value for solving these kind of troubles.
