This machine is a new type of high performance Eddy current electromagnetic adjustable speed grinder. Has a beautiful appearance, reasonable structure, convenient operation, speed range, turn the flexible, dumping of large, stable running, low noise, high efficiency grinding, can solve the workpiece overlap vibration grinding machine, grinding problems such as unevenness. Especially for lesser small artifacts, a thicker oxide film and a large Burr of workpiece, processing difficulties in the Eddy current in the vibration machine grinding machine for a short time to achieve the desired results.
