金刚石或立方氮化硼(CBN)铰刀加工出的孔,尺寸分散度小,几何形状精度高(可达0.002mm),表面粗糙度小(R_α<0.4～0.2μm),刀具寿命长且生产率高,目前已广泛用于加工液压元件的主阀孔、机械和仪表各种精密孔的最终加工上。现就该刀具使用中有关问题,介绍如下。一、铰刀的结构与应用金刚石或CBN铰刀是以金属镍和钴等作为粘结剂,把金刚石或CBN的细小颗粒包镶在一定尺寸和
Diamond or cubic boron nitride (CBN) reamers with small size dispersion, high geometry accuracy (up to 0.002mm), small surface roughness (R_α <0.4-0.2μm), long tool life and high productivity High, has been widely used in the processing of hydraulic components of the main valve hole, mechanical and instrument precision machining of the final hole. Now on the use of the tool in question, described below. First, the structure and application of reamer Diamond or CBN reamer is a metal nickel and cobalt as a binder, the diamond or CBN small particles package set in a certain size and
