This machine is a new and efficient eddy current with a frequency control grinder. A beautiful appearance, reasonable structure, convenient operation, speed range, flexible flip dumping angle is large, smooth operation, low noise, and higher grinding efficiency, and can effectively solve the problem of vibration grinding machine the workpiece overlap grinding uneven . Especially for smaller workpieces, the thicker oxide film and the larger burrs of the workpiece, the vibration machine processing difficulties in a very short period of time to achieve the desired results in the vortex grinder, and improve the two smooth or more. The grinding efficiency is about 10 times the vibration machine, about 20 times the roller.
