目前,我国机床导轨的耐磨性差。提高机床导轨铸铁材料的耐磨性是提高机床耐用度的主要措施。国外常常采用密烘铸铁,加镍、铬、钼、铜、钛、钒的合金铸铁和含磷铸铁来提高机床铸铁的耐磨性。 根据党的“自力更生,奋发图强”的革命精神,结合我国机床铸造的特点,充分利用国内资源, At present, the wear resistance of our machine tool guide is poor. Improve the wear resistance of the machine tool guide cast iron material is to improve the durability of the main measures. Abroad often use close cast iron, plus nickel, chromium, molybdenum, copper, titanium, vanadium alloy cast iron and phosphorus-containing cast iron to improve the wear resistance of machine cast iron. According to the revolutionary spirit of “self-reliance and work hard with strength and strength” of the party, combined with the characteristics of China’s machine tool foundry, make full use of domestic resources,
