An optical presetter for precision alignment of a tool on a machine turret to be positioned on a lathe or the like. The presetter includes a bale support, a light source, an adjustable carriage, and a viewer with a reference. When a tool is mounted on a turret and the turret is mounted on the carriage with the tool in the light beam; the tool can be precision aligned by moving the tool relative to the turret and noting the change of the tool image on the viewer.

Presetter gauge

A machine tool collet having a generally cylindrical body with a longitudinal axis. The collet is divided into a plurality of segments each having front and rear surfaces and endfaces with recesses. The recesses hold biasing springs which force each segment away from the adjacent segment.

Machine tool collet

An optical presetter for precision alignment of a tool on a machine turret to be positioned on a lathe or the like. The presetter includes a base support, a light source, an adjustable carriage, and a viewer with a reference. When a tool is mounted on a turret and the turret is mounted on the carriage with the tool in the light beam; the tool can be precision aligned by moving the tool relative to the turret and noting the change of the tool image on the viewer.

Pre-setter for positioning tooling on turrets

Bar stock feed apparatus generally comprising an elongated tubular member adapted to receive a length of bar stock therein and a standard for supporting the tubular member in a feed position wherein the tubular member is aligned with the lathe spindle and in a second position wherein the tubular member is out of alignment with the spindle so that the stock can be loaded therein. A fluid actuated plunger is received in the tubular member and is advanced by pneumatic pressure supplied to the rear of the tube through an annular passageway formed by a pair of concentric tubes. A locking mechanism, which clamps the feed tube in position, includes a valve which controls the flow of air to the plunger and automatically interrupts the supply of air when the tubular member is not locked in place. A safety valve is positioned to be contacted by the tubular member when in its operative locked position and serves to bleed air from the supply line when the tubular member is not in the feed position.

Bar stock feed apparatus

An adjustable tool holder for use on machine tools such as lathes or the like is disclosed and comprises a base member adapted for mounting on the machine tool and for adjustably mounting a tool holding assembly therein. The features of the base member and the tool holding assembly permit adjustment of a tool bit along X, Y and Z axes with extreme precision.

Adjustable tool holder

A collet assembly comprising a spring body member having a cylindrical rear portion and a plurality of spring fingers extending axially therefrom, with an annular bead on the external periphery of the spring fingers near the distal end thereof. Work gripping pads for gripping the exterior of the workpiece are mounted on each of the fingers, and the pads have a groove on the interior thereof for mounting the pads on the beads on the spring fingers. The pads have an exterior surface which forms a frusto-conical cam surface for cooperative engagement with an actuator sleeve, and the pads are free to rock slightly axially on the beads when the collet is opened or closed. Also disclosed are the spring body and the pads for use therewith.
