A machining center is provided with: a base; a table that supports a workpiece; a main-shaft head that causes a tool to rotate around an axis of rotation of a main-shaft; a Z-axis drive device that causes the table to move with respect to the base along a Z axis parallel to the axis of rotation of the main-shaft; a W-axis drive device that causes the main-shaft head to move with respect to the base along a W axis parallel to the axis of rotation of the main-shaft; and a control device that controls the Z-axis drive device and the W-axis drive device so as to cause the tool to process the workpiece by causing the table and the main-shaft head to move along the Z axis and the W axis, respectively.

While the loading member supporting mechanism moves the loading member from the workpiece set state to the workpiece retracted state and returns to the workpiece set state again, the displacement drive unit and the rotation drive unit perform an operation of disposing the workpiece holding portion arranged at the processing position to the replacement position and an operation of disposing the workpiece holding portion disposed at the replacement position to the processing position in a trajectory in which the loading member does not interfere with the shoe.

It is possible to improve workpiece machining efficiency by efficiently receiving and delivering a workpiece from/to each workpiece holder and shortening a time required for workpiece conveyance. A workpiece conveyance system is a workpiece conveyance system that receives and delivers workpieces W to be machined to n spindles (workpiece holders, where n is an integer satisfying n≥2) that hold and rotate the workpieces W, and includes a main loader including n+m main loader chucks (where m is an integer satisfying m≥1) that receive and deliver workpieces from/to the n spindles or n relay loaders disposed corresponding to the n respective spindles to receive and deliver the workpieces W from/to the main shafts.

The present invention relates to a machine tool for machining surfaces of in particular rotationally symmetrical workpieces (7), comprising at least one machining station (1, 2), at least one loading station (3) and/or unloading station (4) for the workpieces to be machined and/or the machined workpieces, a loading device (6) for transferring the workpieces (7) from one station (1, 2, 3, 4) to an adjacent station (1, 2, 3, 4),

characterized in that the loading device (6) comprises a rotatably driven sliding device (8), a drive (9) for the sliding device (8) and a rotatably mounted and braked guiding device (10),

wherein driving the sliding device (8) initially causes a workpiece (7) to be pressed by the sliding device (8) against the guiding device (10), after which the workpiece (7) abutting against the sliding device (8) and abutting against the braked guiding device (10) indirectly moved by the sliding device (8) is transferred onto a circular arc track from one station (1, 2, 3, 4) into an adjacent station (1, 2, 3, 4).

The present invention discloses an automatic loading and unloading processing system including: a material storage assembly, which is used to store workpieces; a positioning mechanism which is arranged on a worktable; and a transport mechanism, which is used to transport the workpiece to be processed from on the material storage assembly to on the positioning mechanism and transport the processed workpiece into the material storage assembly, wherein the material storage assembly includes: a material tray; a plurality of fixing bases; a motion mechanism; and a plurality of tooling sub-boards for fixing the workpiece, and the tooling sub-boards are fixed on the fixing base, and the motion mechanism controls the movement of the material tray so that the position of the tooling sub-boards corresponds to the position of the transport mechanism; and the transport mechanism includes: an auxiliary jaw loading and unloading system that is arranged at one support end of the worktable to grab the tooling sub-boards and moves along an X axis and/or Y axis of the machining center; and a main spindle jaw loading and unloading system that is arranged on a machining main spindle to grab the tooling sub-boards grabbed by the auxiliary jaw loading and unloading system and moves along the Z axis of the machining center. The present invention realizes the function of automatic loading and unloading, and improves the working efficiency and the consistency of workpiece processing.
