Internal bore grinding machines tool is equipped with two grinding wheel spindles. A grinding wheel spindle with the small out diameter adopts a "C" font of sleeve supplied with the machine for installation. With the observation from the end of belt pulley, the main shaft of grinding wheel rotates clockwise. 2. Gear Head Stock.

Machine bases are often constructed from granite or special epoxies to minimize thermal expansion and vibration. Any vibration in the machine will directly affect the surface finish of the part. Naturally, grinding wheels create friction, which in turn creates heat. Heat from the workpiece may be transferred to the machine.
