用大车床车削长、薄、大直径内筒零件保证互相形位公差的研究

Ensuring the Shape and Position Tolerance for Large Lathe Turning the Long, Thin, Large Diameter Inner Tube Parts

在用C6180A大车床车削长、薄、大直径内筒零件时,出现了多个外、内径尺寸的互相形位公差,难以达到图样的技术要求,在分析原因后,通过改进定位工装、修改工艺方案后,使零件达到了图样要求,解决了生产实际问题。

In C6180A large lathe turning long, thin, large diameter inner tube part, the emergence of mutual tolerance of form and position a plurality of inner diameter, it is difficult to achieve the requirements of drawings. After analyzing the causes, by improving the positioning fixture, modifying the process scheme, the components meet the design requirements, and actual problems in production are solved.
