MPI 8”x18” 100N Holding Force Rare Earth Surface Grinder Permanent Magnetic Chuck SGC-200450-REN

Description

The MPI Rare Earth Surface Grinder Chuck offers exceptional holding force combined with high quality and favorable pricing. It is a simple, low maintenance clamping device primarily used as an accessory to grinders intended for precise surface grinding of very small, thin parts up to large workpieces and electrical discharge machining (EDM).

This type of magnetic chuck is a manually operated permanent magnetic chuck. It is turned ON or OFF by turning the actuator shaft 180° by means of an allen key. The chuck is independent of any external power supply during operation. This offers safety, constant holding power, accuracy and no heat development causing expansion.
