我国机床液压行业,孔的精密加工一直是生产的关键。多年来,虽然不断改进技术,采用刚性镗铰、研磨和珩磨工艺,使用刚性镗铰机床及珩磨机床,但尚不能保证阀孔的尺寸精度和几何精度达到完全互换的要求。采用电镀金刚石铰刀对孔进行精密加工,便可获得理想的效果。电镀金刚石铰刀是近年来出现的孔精密加工用的先进刀具,在国外得到广泛应用,国内 China’s machine tool industry, precision machining hole has been the key to production. For many years, rigid continuous boring, grinding and honing techniques have been used to improve the technology. Rigid boring machines and honing machines have been used. However, the dimensional accuracy and geometrical accuracy of the valve holes can not be guaranteed to be fully interchangeable. The use of electroplated diamond reamers on the hole for precision machining, you can get the desired effect. Electroplating diamond reamer appears in recent years, precision machining of the hole with advanced tools, widely used abroad, the domestic
