A turret belt grinder having multiple contact wheels of different diameters mounted on tooling support members that are adjustably attached to a turret frame. The turret assembly is rotatably supported on flanged bushings bearing on a ring plate to revolve 360 degrees about, and concentric to, the axis of the motor drive shaft. A closed loop belt is transported in a fixed geometric pattern on the radial surface of the contact wheels. Each of the contact wheels may be rotated to a common work station to produce infinite belt angles and chages in wheel diameters. A friction rotor lock functions to fix the turret position to accommodate a variety of abrasive machining applications. The abrasive belt is driven by a V-belt which transmits power from the motor shaft to a contact drive wheel. Wheel mount member assemblies provide adjustment of the V-belt tension, abrasive belt tension and belt tracking camber. A leverage spring release mechanism permits rapid abrasive belt changes and maintains belt tautness. It also provides a means for exchanging contact wheels to meet contouring specifications. The turret and motor supporting ring plate is attached by coupler bolts to the housing assembly which also functions to enclose, guard and dust evacuate the turret assembly. Adjustable sliding panels operate to further limit abrasive belt exposure at the work station opening. A hinged door provides access for belt changes and maintenance. Attached to the housing exterior is a mounting base and adjustable belt work rest.
