摘要： A machine tool comprises first and second rotary machine axes (10,16) which are parallel and mounted on a base in fixed locations relative to the base, a linear machine axis (8) which is carried by the first rotary machine axis, and a rotary positioning mechanism (30) which is carried by the linear machine axis, wherein the rotary positioning mechanism provides rotation about a support rotational reference axis (32) that is parallel to the first and second rotary machine axes. A further machine tool includes a linear positioning mechanism (40) which is carried by the linear machine axis that provides linear movement parallel to the linear machine axis. The rotary and/or linear positioning mechanisms enable the workzone of the machine tool to be extended and/or reconfigured.

摘要： A workpiece holding assembly (20) comprises a magnetic chuck (22), and first and second separate sets of workrests for engaging with the outer circumferential surface of an annular workpiece (40, 60). The workrests are configurable such that when the outer circumferential surface of the workpiece (40, 60) is ground with the chuck Urotating in one direction, the outer circumferential surface is only urged in contact with the first set (26, 28) of workrests, and when an inner circumferential surface of said workpiece is ground with the direction of rotation of the chuck reversed, the outer circumferential surface is only urged in contact with the second set (30, 32) of workrests. Grinding methods using such a workpiece holding assembly are also described.

摘要： A machine tool (40) comprises first and second support arms (44,46), and a rigid structure (42) which couples the first support arm to the second support arm. A first rotary drive (50) is operable to rotate the first support arm and the rigid structure relative to each other about a first rotational reference axis (53), and a second rotary drive (52) is operable to rotate the second support arm and the rigid structure relative to each other about a second rotational reference axis (55), wherein the first and second rotational reference axes are parallel and spaced apart by a fixed distance. A control arrangement (47) is configured to control the first and second rotary drives such that a workpiece mount carried by the second support arm follows a predetermined path relative to a tool mount carried by the first support arm in a plane perpendicular to the rotational reference axes.

摘要： A tool mounting assembly (4) for coupling a tool (2) to a rotary drive of a machine tool. The assembly comprises a mount (6) having a longitudinal axis (10) and defining an engagement surface (22) for engaging with a tool to be rotated about the longitudinal axis, and at least three independently expandable chambers (20) within the mount for receiving a flowable material. Each chamber is mechanically coupled to a respective portion of the engagement surface, such that an increase in the pressure within the chamber above a predetermined threshold expands the chamber, which causes the coupled portion of the engagement surface to move in a radial direction relative to the longitudinal axis.

摘要： A fluid mixing device comprises a tubular structure (30) including an inner wall (32) which defines a channel, the channel having a central longitudinal axis (34) and being configured to convey a fluid in a longitudinal direction along the structure, and a plurality of flow deflection elements (36, 38) which are supported by the structure and located within the channel. Each flow deflection element (36, 38) defines a surface that extends between a first leading edge (40, 42), which extends transversely around a first portion of the inner wall (32) of the hollow tubular structure, and a first trailing edge (44) which is spaced in the longitudinal direction from the first leading edge and extends radially inwardly from the inner wall.
