4. The Operation of a Belt Grinding Machine

The sand belt is put into straight-lined motion by the motor over the belt roller.

The sand belt is pressed on the piece of work by the pressure shoe. Thereby the abrasive grains remove very fine shavings in form of abrasive dust from the piece of work. Because of the movability of the grinding table and the pressure shoe all parts of the surface of the piece of work are reachable.
