在圆台平面磨床上加工零件常使用两种工艺用垫:隔磁垫和漏磁垫。一、隔磁垫在M7331圆台平面磨床上,磨削薄片圆形零件两面的不平行度,一般在0.015毫米左右。加工精度差,达不到图纸要求、效率低。采用隔磁垫的方法磨削,两面的不平行度可以达到0.003毫米,并且提高工效4～5倍。以弧齿锥齿铣齿机的一个调整垫(材料45钢)为例。1.零件要求(图1):2.隔磁垫(图2):采用材料为铸铁或钢。3.工作原理:加工薄片圆形零件,若用圆台平磨磁盘直接吸紧零件进行磨削,由于磨削前零件未形成好的基准面,所以磨后两面的平面度低。如果采用以黄油或二硫化钼将零件粘在隔磁垫槽内加工的方法,则因受隔磁
Two types of process pads are commonly used to machine parts on a circular table grinder: a magnetic spacer and a magnetic leak pad. First, every magnetic pad In the M7331 round table surface grinder, grinding non-parallelities of the two sides of the circular piece, generally about 0.015 mm. Processing accuracy is poor, not up to the drawings, low efficiency. Grinding method with magnetic pad, both sides of the non-parallelism can reach 0.003 mm, and improve work efficiency 4 to 5 times. Take an adjusting pad (material 45 steel) of a spiral bevel gear milling machine as an example. 1. Parts requirements (Figure 1): 2. Magnetic mats (Figure 2): The material is cast iron or steel. 3.Working principle: Machining thin circular parts, if the disc flat grinding disc direct suction parts grinding, because the grinding parts before the formation of a good reference plane, so after grinding the flatness of both low. If you use butter or molybdenum disulfide to stick parts in the magnetic separation mat groove processing method, then due to magnetic isolation
