(2) Processing Principle
It adopts industrial-grade high-speed centrifugal dual-movement grinding technology. A high-power motor drives the thick cast steel main turntable to perform a revolving motion, and at the same time, drives four sets of heavy-duty processing barrels to rotate at high speed in the reverse direction through heavy-duty gear set transmission, generating ultra-strong centrifugal force.
Under the action of centrifugal force, the workpieces and grinding abrasives in the barrels are closely attached to form a high-density grinding layer, which conducts all-round and in-depth grinding and polishing on all surfaces of the workpieces. It can quickly remove burrs and sharp edges of large and heavy metal parts to achieve a high-precision mirror grinding effect with high processing efficiency and excellent surface finish, fully adapting to the large-scale and continuous processing needs of large metal parts.
