为了改善劳动条件和提高生产效率,实现以磨代刮的新工艺,1968年我们对一台 M7130普通平面磨床进行了改装,成了高精度镜面磨床,精度达到0.002毫米/米,光洁度达▽12,下面将改装的部分加以介绍。一、设计新磨头原磨头前端采用长滑动轴承,因为它有发热量大,配合间隙大和刚性差等缺点,所以新磨头(图1)就是针对改进这些缺点进行设计的,例如,为了 In order to improve the working conditions and improve production efficiency, to achieve a new process with scraping scraping, 1968 we have a M7130 ordinary surface grinder has been modified to become a high-precision mirror grinder, accuracy of 0.002 mm / m, finish ▽ 12 The following will be modified to introduce the part. First, the design of the new grinding head The original grinding head with long plain bearings, because it has a large heat, with the gap and poor rigidity and other shortcomings, so the new grinding head (Figure 1) is designed to improve these shortcomings, for example,
