A carriage assembly includes a housing having first and second pieces each defining a recess that has a bearing surface with raised dimples. The first and second pieces are assembled to each other such that the recesses are aligned to form a cylindrical hole. A bushing is received in the hole and has an outer surface disposed against the dimples of the first and second pieces. The dimples are deformed during assembly to secure and locate the bushing within the cylindrical hole.

A safe mode cross slide system having a cross slide with a back plate, a front plate and a saddle. The back plate can have a pair of end caps, a pair of linear guides, a first ball screw, a first gear box, a first servo motor, a first drive, and a first manual feed knob and the front plate can have a pair of end caps, a pair of linear guides, a second ball screw, a second gear box, a second servo motor, a second drive, and a second manual feed knob. The system can have a power supply, a communications hub with a processor and data storage.

A reprocessing apparatus, in particular a cleaning and/or preserving apparatus, for tools, tool holders and/or tool units is proposed, with at least one reprocessing unit, in particular for a reprocessing of used and/or contaminated tools, tool holders and/or tool units, with at least one holding unit for an exchangeable holding of the tools, tool holders and/or tool units, and with at least one handling unit which is configured, for an execution of a cleaning process on the tools, tool holders and/or tool units, to bring the holding unit and at least one cleaning region of the reprocessing unit together in an at least semiautomated manner, and after execution of the cleaning process, to remove the holding unit and the cleaning region of the reprocessing unit from each other in an at least semiautomated manner, and/or after execution of the cleaning process, to bring the holding unit and at least one further cleaning region of the reprocessing unit together for an execution of a further cleaning process.

Cement or other liquid-like material fills the hollow tubes of a machine tool under construction. The machine tool structures are held rigidly against a fixture while the substance dries. The machine tool so constructed is relatively lightweight and rigid, and obviates the need for precision machining of large portions of the apparatus.

Present invention relates to a rotary positioner that allows a welding table's work surface to be set at an angle as desired by a user. Two vertical frames can move and slide along the length of a chassis-bar to adjust the distance between the two vertical frames. As long as the length of a welding table does not exceed the total greatest distance between the two vertical frames, the present invention can fit any work table or welding table. Caster wheels and height adjustment knobs allow for easy movement and balancing of the rotary positioner.

A reconfigurable interface assembly includes, but is not limited to, a first sub-assembly that is adapted for attachment to a work-piece supporter. The first sub-assembly includes a first brake. The reconfigurable interface assembly further includes a second sub-assembly attached to the first sub-assembly. The second sub-assembly is adapted for attachment to a work-piece manipulator. The second sub-assembly includes a second brake. The first sub-assembly is configured to move the second sub-assembly in a first direction with respect to the first sub-assembly and the first brake is configured to inhibit movement of the second sub-assembly in the first direction with respect to the first sub-assembly. The second sub-assembly is configured to move the first sub-assembly in a second direction with respect to the second sub-assembly and the second brake is configured to inhibit movement of the first sub-assembly in the second direction with respect to the first sub-assembly.

A machine tool includes a bed, a column which is provided on the bed so as to be erected therefrom, a saddle which is a moving body supported by the column, and a tool spindle which is supported by the saddle and rotates a tool around a rotation center axis extending in a Z-axis direction parallel to a horizontal direction. The saddle has a frame portion which is provided so as to surround the tool spindle. The thickness of the frame portion in the Z-axis direction changes along a Y-axis direction parallel to a vertical direction, and becomes maximum at a first position-(Pa) closer to an upper end portion of the frame portion than a lower end portion of the frame portion.

A machine tool includes a table, a first guide portion and a second guide portion that guide the table in the Z-axis direction and are arranged apart from each other in an X-axis direction, and a bed that includes a first guide mounting portion and a second guide mounting portion on which the first guide portion and the second guide portion are mounted respectively, and is provided with an opening portion which is located between the first guide mounting portion and the second guide mounting portion and penetrates in a Y-axis direction. The first guide mounting portion and the second guide mounting portion are respectively provided with a first facing surface and a second facing surface which face each other across the opening portion. The bed further includes a rib portion which is located in the opening portion and connected to the first facing surface and the second facing surface.

A machine tool includes a bed, and a table that is provided on the bed and movable in a Z-axis direction. The table includes a workpiece holder, a table base including a first support portion and a second support portion for turnably supporting the workpiece holder at positions spaced from each other in an X-axis direction, the workpiece holder being mounted on the table base, and a turning device that is provided in the first support portion, and turns the workpiece holder around a turning center axis extending in the X-axis direction. The machine tool further includes a first feeding device and a second feeding device that are provided on the bed and are connected to the first support portion and the second support portion respectively to drive the table in the Z-axis direction.
