A machining jig for rotatably supporting a workpiece comprising: a rotary drive part which rotates a seating part about a rotation axis, a clamp arm which has a rotary type clamp member which cooperates with the seating part to fasten a workpiece at a position separated from the seating part in a direction along the rotation axis of the seating part, a linear drive part which moves the clamp arm in a direction along a rotation axis, a position adjusting part which adjusts a position of the clamp arm in a plane intersecting the rotation axis, and a tilt adjusting part which adjusts a tilt of the clamp member so that a rotation axis of the clamp member becomes parallel with the rotation axis of the seating part.

A machine tool includes a slide table supported by an upper portion of a main body of the machine tool so as to be horizontally slidable, a rotary table provided on the slide table so as to be rotationally indexable about a vertical axis extending in the direction that is orthogonal to the direction of horizontal slide movement of the slide table, and a motor provided in the slide table to rotate the rotary table. A housing space is formed in the main body to house a lower portion of the slide table. At least a part of the motor provided in the slide table is placed in the housing space.

The machine tool includes a workpiece carrier assembly arranged for horizontal movement in parallel to a horizontal axis and a tool carrier configured for carrying at least one tool for machining at least one workpiece by rotating the tool. The workpiece carrier assembly or the tool carrier is displaceable between an operative position in which a workpiece carrier is facing the tool carrier, and at least one inoperative position. The workpiece carrier is arranged to be rotatable to allow for a modification of the angular position of the workpiece in relation to the tool carrier.

A method for machining a metallic member to provide a finished appearance uses a lathe and a scraping process. A metallic member comprising a top portion and a peripheral sidewall is provided, the metallic member is positioned on the worktable. The worktable is rotated with the metallic member, the lathe tool moved backwards and forwards to machine the top portion of the rotary metallic member circumferentially. The lathe tool is moved by the moving device along a predetermined path relative to the worktable to machine curved surfaces of the top portion of the metallic member. The scraping cutter is moved to contact the peripheral sidewall of the metallic member. The scraping cutter is moved along a predetermined path, and the scraping cutter is fed the metallic member to achieve the required shape and finish.

A machine tool comprises a tool spindle which can be positioned in 3 axes and a pivot bridge pivotable about an A axis with a round table for mounting a workpiece pallet supporting a workpiece. Furthermore, in front of the pivot bridge, a mount is provided for a processed workpiece or workpiece to be processed located on a workpiece pallet. Between the mount and the pivot bridge a pallet changer is provided which can only perform a vertical displacement movement and a pivot movement about a vertical axis. Workpiece pallets are picked up and put down only during the vertical displacement movement of the pallet changer, or possibly by pivoting the pivot bridge about the A axis.

The invention relates to a machine (10) for machining and/or measuring a workpiece (49). Machine (10) has a machine frame (18), a first transverse member (24) which is rotatably mounted by means of a first round guide (25) about a first rotational axis (D1) on the machine frame (18) and on which a tool unit (11) with a tool (13, 14) is arranged, where the tool (13, 14) is arranged at a distance from the first rotational axis (D1). Machine (10) also has a second transverse member (40) which is rotatably mounted by means of a second round guide (41) about a second rotational axis (D2) on the machine frame (18), and on which a workpiece clamping device (12) is arranged at a distance from the second rotational axis (D2). The two rotational axis (D1, D2) are aligned parallel to one another.

Disclosed is a five axis machining apparatus. The five axis machining apparatus comprises a base member, a support member, a stationary base, a first moving plate, a second moving plate, a third moving plate, a fourth moving frame, a fifth moving frame and a controller (not shown). The five axis machining apparatus is designed to hold together A, C and X axes thereby resulting in a reduced size without compromising on rigidity that is required for processing metallic job components. The five axis machining apparatus allows independent as well as simultaneous control of X, Y, Z, A and C axes.
