SJ621B ELECTROMAGNETIC GRINDING MACHINE1. This machine is a special machine used for grinding all kinds of the friction surface of automobile pads, can ensure the good roughness of friction surface and the flatness to plate surface. The special structure (annular groove) of the disc pads suit for grinding the "xiali" brake pads and other disc brake pads with the convexities plate.
2 Main characters
The machine has high precision, and is easy to be operated and adjusted. The machine adopt round disc electromagnetism sucking disc, dividing the zone, sucking and releasing automatically. This machine can work continuously and has high efficiency.
