我厂有一种薄壁缸套零件 ,安排在无心磨床上加工 ,由于缸套有肩台 ,所以必须采用切入磨削法 ,用焊接在挡铁上的硬质合金刀块进行轴向定位。缸套在加工过程中由于轴向力的作用 ,其下端始终与硬质合金刀块产生转动磨擦 ,因而常导致缸套下端已倒好角的端面出现毛刺 ,甚至出现锯齿 My factory has a thin-walled cylinder liner parts arranged in the centerless grinder processing, as a result of cylinder shoulder, it must be cut into the grinding method, with carbide welding block on the block for axial positioning carbide. Cylinder liner in the machining process due to the role of axial force, the lower end of the carbide cutter always produces rotational friction, which often leads to lower end of the cylinder liner has a good angle of the surface burr, or even sawtooth
