ABSTRACT:
A belt grinder includes a motor, a driving disc, a contact disc, a grinding belt, and a housing, where the motor and the driving disc are moveable with respect to the contact disc in order to vary the distance between the axis of the contact disc and the axis of the driving disc. An attachment is secured to the belt grinder that includes a contact roll around which the grinding belt is fitted. The center to center distance between the contact roll of the attachment and the contact disc of the belt grinder is maintained as contact rolls of different diameter are used. The motor and driving disc are moveable with respect to the contact disc to vary an angle between the axis of the contact disc and an axis of the driving disc.
