近廿年来,我国机床行业先后试制成功高磷铸铁、磷铜钛铸铁等机床导轨耐磨铸铁。但是,目前我国机床导轨采用提高耐磨性措施的产品仍比较少,不能适应迅速提高机床铸件内在质量的要求,也不适应出口的需要。 为了提高齿轮磨床导轨用铸铁的耐磨性,秦川机床厂与陕西机械学院协作,从19 Nearly 20 years, China’s machine tool industry has trial-produced high-phosphorus cast iron, phosphor bronze cast iron and other machine tool rail wear-resistant cast iron. However, at present, China’s machine tool guide rail with measures to improve the wear resistance of the product is still relatively small, can not meet the rapidly increasing requirements of the internal quality of machine tools castings, nor is it suitable for export needs. In order to improve the wear resistance of the gear grinding machine rail with cast iron, Qinchuan Machine Tool Works and Shaanxi Institute of Mechanical collaboration, from 19
