采用金刚石铰刀对精密孔进行超精加工,已成为我国液压气动元件生产中必不可少的基本工艺手段了。机械部通用基础件局将精密孔加工列为生产液压件的“六大基本工艺”之一,并列入机械部“六五”期间科技攻关项目。目前,金刚石铰孔工艺已在我国液压行业生产中取得可喜进展。例如: 1、对铸铁件阀孔精加工已基本抛开研磨工艺,部分取代了珩磨工艺。提高工效四倍以上。保证被加工孔的尺寸精度分布在0.003毫
The use of diamond reamer precision hole precision finishing, has become China’s hydraulic pneumatic components essential for the production of basic technological means. The General Bureau of the Ministry of Machinery will be classified as a precision hole machining hydraulic parts production of the “six basic processes,” one of the Ministry of Machinery and included in the “Six Five” period of scientific and technological projects. At present, diamond reaming process has made gratifying progress in the hydraulic industry in China. For example: 1, on the cast iron valve hole finishing has basically laid aside the grinding process, partially replaced the honing process. Improve work efficiency more than four times. Ensure that the size of the hole to be machined is about 0.003 millimeter
