In the internal milling machine according to the invention for milling a work piece that rotates during machining with an annular internal milling cutter (5) on the one hand side the Z slide (4a, b) of each tool support (3a, b) includes a pass through opening and on the other hand side the transversal slide (7) supporting the internal milling cutter (5) is move able in the X-direction, the running direction of the mounting surface (1a) of the bed (1) wherein the mounting surface slopes downward in a forward direction. Based on this general configuration and in particular the arrangement of the Z-slides (6a, b) for the at least one tool support (3a, b) outside of the Z-supports (16a, b) for the opposite spindle stock (2) yields advantageous centers of gravity in particular of the move able components and a high level of stability of the machine and therefore high level of machining precision of the machine.

An apparatus and method are provided for three dimensional planing of a workpiece.

The control module includes a controller and a plurality of actuators to provide precise displacement of the machine table, spindle, cutting tool and the workpiece for planing surface features into the workpiece.

A method of operating a part cleaning machine includes removably attaching a part to a part holder. A selected first one of a plurality of tools is transferred from a tool holder to a tool chuck to perform a desired cleaning operation. The selected first one of the tools is positioned in a pre-defined tool cleaning position by moving a chuck holder along an axis on a tool positioning plane. The part is positioned in a pre-defined part cleaning position by at least one of moving a cradle along an X axis, rotating the cradle about a first cradle axis, or rotating the part holder about a second cradle axis. The desired cleaning operation is performed on the part with the selected first one of the tools, with the part in the pre-defined part cleaning position and the selected first one of the tools in the pre-defined tool cleaning position.

A part cleaning machine includes a cradle moveable along an X axis, and rotatable about a first cradle axis. A part holder is attached to the cradle, and is rotatable about a second cradle axis. A chuck holder is moveable on a tool positioning plane that is perpendicular to the X axis. A tool chuck is attached to and moveable with the chuck holder. A tool holder is moveable relative to the chuck holder along the X axis. A plurality of tools are releasably attached to the tool holder for selective attachment to the tool chuck. A machine controller is operable to control movement of the chuck holder, the tool chuck, and the tool holder to transfer a selected one of the tools between the tool chuck and the tool holder, and position an appropriate tool and the part in different positions for several different cleaning operations.

A cutting apparatus includes a rotatable holding table having a rectangular holding surface, a cutting unit having a cutting blade mounted to a rotatable spindle, and a sensor unit detecting a tip of the cutting blade entering between a light projection section and a light reception section. The sensor unit has an upper end located to be lower than a lower end of the holding table in a Z direction and is located below the axis of the spindle or an extension region of the axis, and when short sides of the rectangular holding surface are set parallel to a Y direction, an upper side of the sensor unit is opened to allow the cutting blade to enter between the light projection section and the light reception section.

The present application comprises a loading gantry with at least one carriage traversable on a horizontal guide rail, in particular for the transport of workpieces between stations of a production system. In accordance with the application the loading gantry includes a media station which in at least one position of the carriage releasably can be mechanically coupled with the same in order to produce at least one media connection between the media station and the carriage.

A rim drilling and milling machine has a base (10), a column (20), a turret (30), a saddle (40), a table (50), and a fixture unit (60). The fixture unit (60) has a foundation (61) and four clamping seats defined as two first clamping seats (63A) and two second clamping seats (63B). The first clamping seats (63A) are slidably mounted on the foundation (61) along a first radial direction, and are disposed at positions diametrically opposite in the first radial direction. The second clamping seats (63B) are slidably mounted on the foundation (61) along a second radial direction perpendicular to the first radial direction, and are disposed at positions diametrically opposite in the second radial direction. The four clamping seats can clamp at four equiangular points of a wheel rim.

A tool carrier assembly for use at a machine tool, which includes at least one workpiece-carrying spindle for rotatably driving a workpiece received in the workpiece-carrying spindle. The tool carrier assembly includes a first slide being movable in a first direction, a tool carrier being supported on the first slide and configured to hold a plurality of tools, a tool drive unit including a tool drive for engaging with one of the plurality of tools held by the tool carrier to rotatably drive said tool, when tool is arranged at a tool drive position with respect to the tool drive, and a drive mechanism for driving movement of the first slide together with the tool carrier in the first direction relative to the tool drive position, when the tool drive is disengaged with tool, to relatively move another tool of the plurality of tools into the tool drive position.

A machine tool has: a main shaft head that supports the main shaft; a main shaft head support part which supports the main shaft head such that the main shaft head can rotate around a first axis that extends perpendicular to the main shaft axis of rotation; a first rotary feed shaft device which is provided in the main shaft head support part, and rotates and feeds the main shaft head around the first axis; a saddle which supports the main shaft head support part such that the main shaft head support part can rotate around a second axis that is perpendicular to the first axis and inclined with respect to the vertical direction; and a second rotary feed shaft device which is provided in the saddle, and rotates and feeds the main shaft head support part around a second axis of rotation.
