在机器制造业中,广泛地连用金属高速切削,是保证提高劳动生产率的许多方法之一。高速切削要依靠工人熟练的使用镶有硬质合金的刀具。 在金属加工工业中,车削工序占极大的比重。如用一般几何形状的硬质合金车刀车削时,在极大多数情况下,切下来的切屑成带状;同时,这种切屑具有很 In the machine tool industry, extensive use of high-speed metal cutting is one of the many ways to ensure increased labor productivity. High-speed cutting to rely on the skilled use of workers inlaid with carbide cutting tools. In the metalworking industry, the turning process accounts for a large proportion. In the case of turning with a carbide cutting tool of a general geometry, in most cases the chips are cut into strips; at the same time, the chips have a very
