高速鋼刀具虽經热处理,而切削性能仍未達到最高要求,一般在沉重負荷工作下,刀具磨損仍很快。根据苏联先進經驗,中温滲硫可以大大的提高刀具切削性能,使用寿命可以提高1至數倍。根据專家建議,中溫滲硫有固体和液体二种方法。我厂根据现有設备条件,先後对这兩种方法進行了試驗,效果都很好,它的优點如下: Although the high-speed steel cutting tool heat treatment, and cutting performance has not yet reached the highest requirements, generally heavy load work, tool wear and tear is still fast. According to the advanced experience of the Soviet Union, medium temperature sulfurization can greatly improve the cutting performance of tools, the service life can be increased by 1 to several times. According to expert advice, temperature and sulfur infiltration of solid and liquid two methods. I plant under the existing equipment conditions, has conducted tests on these two methods, the effect is good, its advantages are as follows:
