A certain proportion of metal parts and abrasives are put into the closed cylinder. During the rotation of the cylinder, grinding occurs between parts and abrasives, and between parts to remove burrs.
There are special deburring machine and centrifugal deburring machine.
Abrasive can be quartz sand, sawdust, alumina, ceramics, dolomite, silicon carbide, metal ring, etc. Select according to the material, shape and size of the parts, as well as the burr position and size.
With this method, the deformation of parts is small, the equipment is simple, easy to operate, the abrasive source is wide, the economy is good, but the big burr is difficult to remove.
