我厂采用刚性镗铰新工艺加工各种换向阀阀孔已有三年多的历史。实践证明,只要刀具制造合理,机床调整维修适当,对加工HT30～54铸铁阀体,在成批生产中,能够保证被加工孔的形状误差在0.005以下,光洁度稳定在▽9以上,取代精镗和珩磨工序是完全可能的。生产效率成倍提高,解决了阀体生产的关键工序。

I plant a new rigid boring process of processing a variety of valve valve hole has been more than three years of history. Practice has proved that as long as the manufacture of a reasonable tool, machine adjustment and maintenance appropriate for the processing HT30 ~ 54 cast iron valve body, in mass production, to ensure that the shape of the hole error is less than 0.005, smooth finish at ▽ 9, instead of fine boring And honing process is entirely possible. Production efficiency doubled to solve the key process of the valve body production.
