在机械加工行业,特别是液压元件生产厂家,在加工制造套类零件时存在椭圆变形、产品报废的难题.由于套类零件具有以下特点:直径尺寸比较大,长度尺寸比较短,壁厚比较薄,形位公差要求比较高等.在加工成形后会产生严重的椭圆变形,因此,针对以上特点对套类零件的加工工艺进行适当改进,问题就迎刃而解了.%In the machine-finishing industry, specially the hydraulic pressure part manufacture,the ellipse deformation frequently happens ,so that the products are scrapped. This article takes processing turbo-charged cylinder jacket as an example,to give the solution and measure that this question is easily solved.
