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.

An all-directional profiling machine has a foundation. A profiling device is disposed on the foundation. The profiling device swings leftward and rightward at the same height relative to the foundation. An upright post is disposed at one end of the profiling device and has a terminal portion extending upward. A workbench is pivotally connected to the terminal portion of the upright post. The workbench tilts vertically and swings horizontally relative to the upright post. Therefore, the all-directional profiling machine performs a multi-angle profiling cutting process without demounting a workpiece repeatedly such that the processing of oblique surfaces is quicker, simpler and more precise, so as to not only meet various requirements of different processing angles but also feature enhanced processing efficiency.

An apparatus for orienting and positioning a workpiece (4) relative to a laser beam (3) of a laser processing machine is proposed. The apparatus is equipped with an apparatus base (5), with a workpiece locating device (6) which receives the workpiece (4) to be machined and with a movement device (7) exhibiting at least three axes which moves the workpiece locating device (6) relative to the apparatus base (5). The movement device (7) is equipped with a rigid body (12) and with a first rotary drive which generates a torque around an axis of rotation B and drives the rigid body (12) to rotate around the axis of rotation B relative to the machine base (5).
