Turbulence in the disk's rotational motion is causing friction with the finishing machine. Upper drum, the middle drum, disk, been separated into a rotational motion of the disk, and the rising turbulence vortex causes the drum and the upper middle of the protruding portion of the drum or polishing will cause friction on the wall. Features Low vibration / low noise design, the central control system, high speed / large abrasive disk, drum adjustable, abrasion resistance, labor costs
