Internal Grinding Wheels

The internal grinding wheels is a cylindrical grinding wheel with a round thouch hole. It made by high quality abrasives of aluminum oxide and silicon carbide. The internal grinding wheels widely used for are used in internal and external faces of ball & roller bearings, barrels, rings, compressor parts, injection nozzle parts, crankshaft, connecting rod ends, gun barrels and bores, hydraulic cylinders and pneumatic cylinders etc.
