A machine tool includes a trough which collects chips; a mobile unit which is located above the trough and moves in the longitudinal direction of the trough on a bed, is configured from a first beam member, a second beam member, and a connecting member connecting the first beam member and the second beam member, and is formed with a hollow that opens toward the trough from above; a first guide which supports the mobile unit in such a manner that the mobile unit is movable in the longitudinal direction of the trough; a second guide which faces the first guide across the trough, and supports the mobile unit in such a manner that the mobile unit is movable in the longitudinal direction of the trough; and a cradle, both ends of which are supported by the first beam member and the second beam member.

A machining apparatus includes a first frame including a first surface formed along a Z-axis direction and a second surface formed along a Y-axis direction. An X-axis moving mechanism and a Z-axis moving mechanism are disposed on the first surface side of the first frame. A Y-axis moving mechanism is disposed on the second surface side of the first frame. A second frame supports the first frame from the second surface side of the first frame. An A-axis rotating mechanism, a B-axis rotating mechanism, and a supporting mechanism that supports an object to be machined are moved by the Y-axis moving mechanism. The t Y-axis moving mechanism is disposed in a space located below the first frame in the Z-axis direction, and formed by the second flame.

The purpose of the present invention is to improve the machined-surface quality of a curved surface of a workpiece without reducing the machining speed when the curved surface is subjected to removal machining. Provided is a workpiece machining method in which a rotating table on which a workpiece is placed and a tool are relatively moved along two linear movement axes orthogonal to each other, the workpiece is rotated about each of a first turning axis and a second turning axis orthogonal to each other by the rotating table, and at least one curved surface of a protruding curved surface and a recessed curved surface is subjected to removal machining. The method includes: disposing the first turning axis so as to be parallel to a first linear movement axis of the two linear movement axes, the motor load during linear movement in the first linear movement axis being relatively small; disposing the second turning axis on a plane perpendicular to the first linear movement axis; and subjecting the curved surface to removal machining along the direction of curvature while moving the workpiece along the first linear movement axis and rotating the workpiece about the second turning axis.

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.

A combined transfer and storage device for machining includes a storage level, a transfer device, at least one machining interface, and a feeding interface. The storage level has two or more storages that are spaced apart from one another in a longitudinal direction and storage spaces for workpiece carriers, which are arranged one above the other for holding blanks or machined workpieces. The transfer device extends in the longitudinal direction. The machining interface is used for directly or mediately coupling with a machine tool. The feeding interface is accessible for a driverless transport vehicle. The transfer device accomplishes a workpiece transfer between the feeding interface, the storage level and the at least one machining interface. A manufacturing line is provided with a combined transfer and storage device and with at least one manufacturing system having at least one machine tool and a handling cell.
