进一步提高冶金机械零件加工质量和生产率的新方法

New Method of Increasing Working Quality and Productivity for Metallurgical Machinery Parts

在机械加工最后一道工序时，按中间公差加工、按中间公差验收，可以令零件达到百分之百的互换，装配顺利，不返修，产品质量和生产率均可得到进一步的提高。

When the final procedure is machined, working, checking and accepting in accordance with intermediate tolerance can make parts quality and productivity further increase, assembly more smoothly, exchanging rate reaching 100%, and without return repairing.
