在劳动生产率迅速增长的基础上,工业产品产量的增加,首先是广泛地采用了新的技术和先进工艺的结果。特别是在工艺过程中采用了硬质合金刀具来切削金属。 目前这些硬质合金材料不仅应用在普通的刀具上,而且已经是逐步地应用到螺旋齿的端铣刀和滚铣刀上。 试验告诉我们,镶硬质合 On the basis of the rapid growth of labor productivity, the increase in the output of industrial products begins with the widespread adoption of the results of new technologies and advanced processes. Especially in the process of using carbide cutting tools to cut metal. At present, these cemented carbide materials are not only used in ordinary tools, but also applied to helical tooth end mills and hob cutter step by step. The test tells us, inlaid carbide
