将一块上下两面磨过的铸铁填块4放在平面磨床的磁性工作台6上(见图),然后将一块毛哗叽布料3盖在填块体上,用细棉绳5把布料与填块体、扎成一体。当磨床的磁性工作台通磁后,由于磨床磁性工作台磁力的作用而把填块体吸住,而毛哗叽布料是非导磁物质,故其上面没有磁力。工件2平放在布料上,工件与布料靠摩擦贴合,便可进行磨削加工。第一件活加工完成后,只需用较硬的猪毛刷刷去布料上的磨屑,就 Put a piece of cast iron block 4 polished on the upper and lower surfaces on the magnetic table 6 of the surface grinder (see picture), then cover a piece of wool cloth 3 on the block body, Block, tied together. When the magnetic table of the grinding machine is magnetically connected, the filling block sucks due to the magnetic force of the magnetic table of the grinding machine, and the wool fabric is a non-magnetic material, so there is no magnetic force on it. Workpiece 2 flat on the fabric, the workpiece and the fabric by friction fit, can be grinding. After the first piece of live processing is completed, only with a hard brush to brush the cloth on the wear debris, on
