| Abstract: | Super Invar Steel is a typical material difficult to process. In this paper, a fixture composed of choker and long-claws is used to improve the accuracy in the roundness of thinwall cylinders made of this material. The results show that a high roundness accuracy can be obtained by using of the fixture proposed of a suitable choker clearance. A roundness of 10 μm can be easily guaranteed on a universal lathe for Ф200 cylinder with 2mm thickness wall. |
