Abstract: An actuating mechanism, particularly for a disc brake caliper, including a screw actuator having a screw 40 and a nut 18 threadably coupled together, an electric drive for driving one of the screw 40 and the nut 18 axially relative to the other and including a stator 20 and a rotor 22, a sleeve assembly including a generally cylindrical sleeve 25 interposed between the rotor 22 and the nut 18 and supporting the rotor 22 for rotation relative to the sleeve 25. The rotor 22 is connected to one of the screw 40 or the nut 18 for rotating the screw 40 or the nut 18. The screw actuator being at least partly mounted within the sleeve 25 and being arranged to bear against a portion of the sleeve assembly to transmit axial thrust to the sleeve assembly, and the sleeve assembly cooperating with an abutment to transmit the axial thrust to the abutment.

Abstract: A collet adaptor and method is provided for adjusting a collet (2) in a machine tool. The collet adaptor has a body or arbor (10) with a cylindrical bore (14) for receiving a cylindrical portion (20) of the collet (2) and a tapered surface (18) at its front end for engagement with a tapered split head (21) portion of the collet (2). An anti-rotation screw (40) prevents rotation of the collet (2) relative to the collet arbor (10). The collet arbor (10) has an accurately ground planar rear surface (5) which is bolted to a planar front face (6) of the headstock (4) of a rotatable spindle so as to correct for errors in concentricity.

Abstract: A computer numerically controlled (CNC) machine has a chuck (2) rotatable about a first axis (A) and a V-block clamp (#) for clamping a workpiece (4) with its central longitudinal axis (C) extending parallel to the first axis (A). The offset (d) between the axes (A) and (C) is known or calculated and the CNC machine is programmed to compensate for the offset (d) during operation of a cutting tool (5) upon the workpiece (4). The V-block clamp (3) can accommodate workpieces of different diameters without having to align the central longitudinal axis (C) of each workpiece to coincide with the axis of rotation of the chuck (2), resulting in a reduction in set up time and an increased concentricity of a ground workpiece compared with conventional CNC grinding machines.
