我厂生产的C360B型普通车床中,有几种平面垫圈,平行度精度要求为5μm,加上需要量大,一直是我厂生产上的难题。为此,我们经过摸索和试验,采用在平磨磁盘上垫上45号钢板的方法,基本上解决了生产垫圈的难题。在平磨磁盘上垫钢板是为了避免工件因过大的磁力而变形。又能利用钢板的导磁性吸住工件。垫钢板后的加工方法如下: 1.平磨磁盘,粗磨工件,并留精磨余量0.05～0.07mm。 2.把预先磨好的钢板吸在磁盘上,进行磨平,再放上工件进行精磨,只需翻磨1～2遍即可。我们在磨厚度为7mm左右的工件时,垫5.6mm I plant C360B-type lathe, there are several flat washers, parallelism accuracy requirements of 5μm, coupled with the large amount of demand, has always been my factory production problems. To this end, we through the exploration and testing, the use of flat grinding pad on the plate No. 45 steel method, basically solved the problem of producing gaskets. Flat grinding disk in the pad plate is to avoid the workpiece due to excessive magnetic deformation. But also use the permeability of the steel plate to absorb the workpiece. After the pad plate processing methods are as follows: 1. Flat grinding disk, rough grinding of the workpiece, and leave grinding allowance 0.05 ~ 0.07mm. 2. The pre-polished steel suction on the disk, polished, and then put on the workpiece for grinding, grinding only 1 to 2 times. When we grind a workpiece with a thickness of about 7mm, the pad is 5.6mm
