模具制造的精加工工序
Finishing process of mold manufacturing
一幅模具是由众多的零件组配而成,零件的质量直接影响着模具的质量,而零件的最终质量又是由精加工来完成保证的,因此说控制好精加工关系重大。在国内大多数的模具制造企业,精加工阶段采用的方法一般是磨削,电加工及钳工处理。在这个阶段要控制好零件变形,内应力,形状公差及尺寸精度等许多技术参数,在具体的生产实践中,操作困难较多,但仍有许多行之有效的经验方法值得借鉴。
A mold is composed of many parts. The quality of parts directly affects
the quality of the mold, and the final quality of parts is guaranteed by
finishing. Therefore, it is important to control finishing. In most
domestic mold manufacturing enterprises, the methods used in the
finishing stage are generally grinding, electric machining and fitter
processing. At this stage, it is necessary to control many technical
parameters such as part deformation, internal stress, shape tolerance
and dimensional accuracy. In specific production practice, it is more
difficult to operate, but there are still many effective experience and
methods worth learning from.
