A process for producing a textured laminate sheet includes a) positioning a substrate material adjacent a barbed face of a metal sheet. The barbed face has a plurality of barbs, and the metal sheet has an opposed face opposite the barbed face. The process further includes b) forcing the metal sheet and the substrate material together to impale the substrate material on the barbs and secure the substrate material and the metal sheet together as a laminate sheet, and c) debossing the opposed face to form a plurality of depressions in the laminate sheet and texture the laminate sheet.

A workpiece support includes a rotating shaft configured to support a workpiece at a leading end portion, a second support supporting the rotating shaft rotatably about a first axis and configured to move the rotating shaft along the first axis, a first support provided between the tool and the second support along the first axis and including a through hole into which a guide bushing unit is configured to be inserted and into which the leading end portion of the rotating shaft is configured to be inserted, and an attachment provided in contact with an outer surface of the leading end portion of the rotating shaft. The guide bushing unit is configured to support the workpiece when the guide bushing unit is in the through hole. At least a part of the attachment is displaceable in a direction away from the first axis.

A turning system allows for slow revolution of a shaft at variable angles so that the work pieces such as cup can be operated on. The work piece could be attached by a hollow cylinder that magnetically attaches to the shaft of the system by placing the hollow cylinder on the shaft. As the shaft enter it contacts an attachment device such as a magnet to hold the work piece on the shaft.

In an embodiment, a machine tool includes two fixed modules and two movable modules each of which having a main spindle, a headstock, and a tool post being integrally formed, and a bed on which these are installed. The movable modules are provided on the bed to be movable in the Y-axis direction, the fixed modules are fixed on the bed on the opposite sides of the these movable modules, and a recess is provided next to the fixed module, the recess being formed by cutting out the bed. The movable modules are movable such that the axis lines of the main spindles of the movable modules are aligned with the axis line of the main spindle of the fixed module or the fixed module. The movable module is movable to the opposite position of the recess.

The invention provides a machine for grinding a work-piece using a grinding tool. The machine comprises a motor for rotating a spindle having a work-piece holder for holding the work-piece. The machine further provides a tool post for mounting and maneuvering the grinding tool relative to the work-piece. The machine includes a print system for printing printable material to the work-piece via additive manufacturing. The printed material may be used to customize a shape of the work-piece after the work-piece has been grinded or turned in the machine. This combination allows for a reduced machine footprint and increased product accuracy.

A machine tool capable of restraining dirt on the footstool and improving setup efficiency. The machine tool includes a machine body having a splash guard surrounding a machining area and a door capable of closing an opening of the splash guard. A footstool is kept mounted on the machine body changeably in place with respect to the machine body. The footstool kept mounted on the machine body is capable of being in a place on an outside of the machine body when the door is closed. The footstool kept mounted on the machine body is capable of being brought to a setup place inside the machining area from the outside of the machine body through the opening when the door is open.

A processing machine includes: a cover body that forms a machining area, and a storage area separated from machining area; an additive manufacturing head; and a head stocker. The additive manufacturing head performs additive manufacturing on a workpiece in machining area. Head stocker stores additive manufacturing head in storage area. Head stocker includes: a head holding part that holds the additive manufacturing head; and a swing mechanism part that swings head holding part centered on a predetermined axis.

A headstock assembly for a machine tool includes a mount having a female threaded bore, a headstock mounted slidably relative to the machine base, a drive member mounted on the headstock, a spindle, and a spindle extension. The spindle has an intermediate segment disposed in a chamber of the headstock and coupled to be driven by the drive member so as to permit the spindle to rotate about a spindle axis. The spindle extension is coupled to be rotatable with the spindle, and has a male threaded segment configured to be in threaded engagement with the female threaded bore so as to permit the headstock to be linearly moved relative to the mount.

A numerical controller controls a machine tool that performs a turning on a workpiece on the basis of a cycle instruction indicated by an NC program. The machine tool includes first and second cutter holders that are mutually coupled by a coupling member, and first and second tools are mounted on the cutter holders in mutually opposing fashion. The machine tool performs a turning according to a complex fixed cycle, in a reciprocal fashion rather than unidirectionally, using the first and second tools, and when the turning by the first tool has been completed and the first tool that has performed a turning is withdrawn, it is possible to perform a turning in the opposite direction by the second tool on the opposite side.
