The invention provides a machine tool capable of expanding the slidable range of the moving unit without making the oil feeding system complicated. A machine tool in which a moving unit slides against a supporting unit with a sliding surface of the supporting unit facing a sliding surface of the moving unit, comprises a first oil groove formed on an unexposed portion of the sliding surface of the supporting unit; a second oil groove formed on an unexposed portion of the sliding surface of the moving unit; and an oil inlet formed on one of the first oil groove and the second oil groove. Lubricant fed through the oil inlet is supplied to the other of the first oil groove and the second oil groove.

A precision-locating dowel pin includes a threaded portion configured for adjustable attachment to a fixed object, a head integrally formed at the top of the threaded portion, and a top surface at the top of the head. The head is selectively machined and treated to provide a radially exterior precision-locating surface.

A modular vise system for holding working objects having a bottom surface, the modular vise system includes a fixture plate and an adjustable vise member configured to secure the working object to the fixture plate. The adjustable vise member includes an elongated body forming a cavity; a flange extending from a side of the elongated body, the flange having an elongated hole extending through a thickness of the flange; a fastener configured to engage with and extend through the elongated hole, the fastener and elongated hole allowing the body to selectively translate relative to the fixture plate; a moveable assembly housed at least partially disposed within the cavity of the body and configured to selectively translate relative to the body; and a gripper coupled to the moveable assembly and configured to secure to the working object.

A surface support for constructing a stained glass design having a flat central surface (12), surface frames (14) bounding all sides of the flat central surface (12), a stationery edge boundary (15) securely mounted on one of the surface frames (14), preferably the frame closest to the artist, 2 side adjustable members (18) mounted in a manner as to be slideable toward or away from one another, and capable of sliding over said flat central surface (12) and the surface frames 14, and a slideable boundary support (24) positioned to slide on side adjustable members (18) toward or away from the stationary edge boundary (15) and slide over the flat central surface (12).

A slide element for a wedge drive, with a slide element receptacle and a drive element between which the slide element is to be placed. In order to achieve a high wear resistance and a simple design, it is proposed for the slide element to have a head rail, which is detachably fastened to the slide element and, as part of the dovetail-shaped side of the slide element, forms the second sliding surfaces on the dovetail-shaped section, by means of which forces are transmitted during the return stroke during which the slide element receptacle is moved away from the drive element.

A T-Nut for use in a machine tool having a tooling plate with an inverted T-shaped channel. The T-Nut comprises a central body having oppositely inclined faces each including an opening forming a cavity extending through the central body, and first and second wedges in slideable communication with the central body inclined faces. Each of the wedges have wings extending laterally beyond the central body to engage upper surfaces of the channel lower wide portion and include a clearance hole extending through a length of the wedge. A rotatable actuation member abuts the first wedge at an end opposite the first wedge mating surface and is internally threaded for a distance from one end thereof. An externally threaded cylindrical shaft is engaged with the internal threads of the actuation member and extends through the first and second wedge clearance holes, the shaft being secured to and non-rotatable with the second wedge. In operation, when tooling is secured to the top surface of the central body and the actuation member is rotated, the first and second wedges are slideably moved symmetrically along the central body inclined faces until the first and second wedge wings engage upper surfaces of the channel lower wide portion while the tooling is simultaneously urged in the direction of the tooling plate until the tooling mounting surface bears against the tooling plate top surface, thereby removably securing the tooling to the tooling plate.
