Patent number: 6145554Abstract: An automatic lathe is provided including a table stand having a top with a plurality of legs coupled thereto and extending downwardly therefrom. A pair of spindle spinning assemblies are positioned on the top of the table stand. Each spindle spinning assembly has a securement rod rotatably mounted thereon which is adapted to releasably secure to an end of a spindle for spinning the same. A carriage assembly is adapted to slide between each spindle spinning assembly. The carriage assembly has a blade mechanism mounted thereon for engaging a front surface of the spindle secured between the spindle assemblies. The carriage assembly further includes a carriage motor functioning to move the carriage in a forward direction upon the receipt of a forward signal and move the carriage in a reverse direction upon the receipt of a reverse signal only when the carriage motor is actuated.Type: GrantFiled: July 30, 1998Date of Patent: November 14, 2000Inventor: Herman Hightower

Patent number: 6134996Abstract: A tool head for use in machine tools includes a base body, a tool shank adapted to be coupled to a machine spindle and protruding axially over the base body, at least one working slide adapted to be displaced essentially transversely with respect to a base body axis, and an adjusting motor disposed in the base body and acting upon the working slide in the direction of displacement by a transmission. In order to attain a compact, easily assembled, and safely operating construction, the transmission includes an output shaft aligned coaxially with respect to the axis of the base body and carrying a drive sprocket which meshes with a tooth rack on the side of the working slide. The adjusting motor also includes a driven shaft aligned with the output shaft on the transmission side.Type: GrantFiled: November 2, 1998Date of Patent: October 24, 2000Assignee: Komet Praezisionswerkzeuge Robert Breuning GmbHInventors: Gerhard Scheer, Erich Feil, Roland Hoerl

Patent number: 6038947Abstract: A tool feed module for a portable lathe machine tool includes a tool block carrying a cutting tool driven by a feed screw incrementally advanced during a cutting procedure by an actuator arm contacting a striker device located on the tool housing. The actuator arm drives the feed screw through an actuator shaft and a one-way drive device permits the actuator arm to pivot in opposite directions while driving the feed screw in increments during pivotal motion in a single direction. To enable reverse rotation of the feed screw and withdrawal of the cutting tool to a starting position rapidly, the actuator shaft is connected to the one-way drive device through a releasable connection that permits rotation of the drive screw by the actuator shaft independently of the one-way drive device.Type: GrantFiled: July 20, 1998Date of Patent: March 21, 2000Assignee: Tri Tool Inc.Inventor: Clement Tremblay

Patent number: 5832590Abstract: A system for performing machining operations on different portions of workpieces comprising a plurality of workstations including a lathe disposed along a predetermined path, in the present instance, a circular path. A turntable supports a plurality of workpiece chucking devices equi-spaced circumferentially around the turntable. The turntable rotates relative to the workstations to position a workpiece chucking device at each workstation permitting different machining operations to be performed on workpieces simultaneously. The chucking devices are moveable on the turntable in a radial direction to present the workpieces to the various tools at the workstations. The workpiece chucking devices include spindle motors and means for synchronizing the speeds of the spindle motors of the chucking devices with the lathe motor.Type: GrantFiled: August 8, 1996Date of Patent: November 10, 1998Inventor: Holger Wuerthner

Patent number: 5526725Abstract: The present invention provides a rapid indexing spindle drive and control apparatus for installation as a retrofit on a cam controlled automatic screw machine to provide the capabilities of variable spindle speed and direction as well as rapid indexing of the spindle in relation to the tool head of the screw machine for stationary tool operations. The apparatus includes a variable speed, low mass servo-motor mounted on the headstock of the machine and connected to the spindle by a 1:1 drive ratio timing belt and pulley system. A cam shaft revolution sensor is mounted adjacent to the screw machine cam shaft and is driven by the cam shaft through a second 1:1 drive ratio timing belt and pulley system. Electronically connected to the servo-motor and the cam shaft revolution sensor is a computer control system which includes a computer and an operator interface unit whereby cam shaft positions and spindle drive commands corresponding to specific cam shaft positions are entered by the machine operator.Type: GrantFiled: March 23, 1994Date of Patent: June 18, 1996Inventors: Neil L. Tremaglio, Angelo F. Tremaglio, Caesar D. Tremaglio, Lawrence E. Rode, Alfred R. Smith
