Abstract: In a steady rest (1) for centering a rotationally symmetrical workpiece (2) in the space, consisting of: two housing halves (4, 5) arranged at a distance from one another and firmly connected together, a middle steady rest arm (6) arranged between the two housing shells (4, 5) that is mounted in the housing shells (4, 5) by means of an actuation piston (7) so as to be moved in an axial direction (3) towards the workpiece (2), and two outer steady rest arms (11, 12) that are in a driving connection with the middle steady rest arm (6) workpieces (2) with the largest possible diameters should be held centerd in the space by the steady rest (one), while retaining the greatest possible movement of travel of the actuation piston (7). This is achieved in that the actuation piston (7) is formed from at least one first advance piston (31) and one second advance piston (32) that are mounted in an axially moving relationship with one another, that a pressure space (33) or (34) is assigned to each advance piston (31, 32) of the actuation piston (7) and that a line (35) emerges in each pressure space (33, 34) through which a pressurized medium can be pressed into the particular pressure space (33 or 34) or drawn out of it.

Abstract: It is already known to detect the position of a pressure element of a steady rest, by means of which its angle levers are actuated, via a traction cable and its rolling position. Possible penetration of liquid via openings in the housing, present for functioning, is avoided by applying sealing air which generates a positive pressure in the housing. After operation, however, penetrated or penetrating liquid could damage the coiling device of the traction cable and impair the position detection.
The present invention is intended to provide the option to provide a more accurate and simpler detection of the position of the pressure element, and thereby further alleviate the problem of penetrating liquid. This is achieved by use of a distance sensor that detects the position of the pressure element and is drained via a drain hole. During operation the drain hole is closed via a sealing air-actuated discharge valve, so that during operation the sealing air cannot escape through the drain hole, but in the rest state, any liquid that has still penetrated drains off.

This is achieved in that a force measuring device (21) is provided on at least one of the two outer steady rest arms (8, 9), by means of which the clamping force (3) of the particular outer steady rest arm (8, 9) is registered during the clamped condition and passed onto an evaluation device (22).

Abstract: In a power-operated chuck (1) with clamping jaws (3) that are guided so they can move radially within a chuck body (2) and are in a drivable connection via intermediate elements with a clamping piston (4) upon which a hydraulic fluid can act in one or both directions and which is inserted in the chuck body (2) in such a way that it can move axially, a pressure sensor (41) installed in the chuck body (2) is provided in order to monitor the hydraulic fluid pressure existing in the pressure chambers (7 and 8) assigned to the clamping piston (4), the pressure sensor (41) being connected to one or both pressure chambers (7, 8) via hydraulic fluid channels (42, 43). Furthermore, the pressure sensor (41) has a receiver assigned to it which is connected to a unit (45) for evaluating the signals received from the pressure sensor (41). This embodiment makes it possible for the pressure existing in a pressure chamber (7 or 8) to be continuously detected both when it is being charged and during operation and for this information to be used in order to control a machine tool.
