ABSTRACT:
A tilting system for centrifugal finishing machines which include a finishing chamber or tub in which parts or work pieces are treated and which is pivoted about a horizontal axis for tilting to remove the parts comprising a hydro-mechanical system which permits free movement from an upright to a tilted position and retards movement from a tilted position to an upright position. The hydro-mechanical system preferably includes a hydraulic linear actuator which has a piston rod with pistons at each end and is connected by a rack and pinion arrangement to the tub. A line extends from one end of the actuator to the other and a one way flow control valve is provided in the line. The tilting motion may be applied manually or by power.
