Patent ID: 10239169

Abstract:
A steady rest (1) for centering a rotationally symmetrical workpiece (2) in relation to a longitudinal axis of a processing machine, having, two housing shells (4, 5) separated by a distance from one another and connected together, an actuating piston (7) mounted in an axially moving arrangement in the housing shells (4, 5) which acts on the workpiece (2), three steady rest arms (8, 9, 10) mounted to the two housing shells (4, 5) in a swiveling arrangement by a bearing pin, and configured to move in concert so as to clamp the workpiece, wherein the clamping forces actually occurring on the steady rest arms (8, 9, 10) can be registered reliably using a force measuring device (21) provided on at least one of the two steady rest arms (8, 9), and passed onto an evaluation device (22).
