Patent number: 5699598Abstract: The machine tool bas a combined slide which is formed of partial slides and is movable in the X direction on two linear guides by means of guide carriages. The two partial slides are supported directly relative to one another by support guides and can be moved in the X direction relative to one another in order to carry out a correcting adjustment or a feed movement. Each partial slide supports a vertical spindle which is movable in the Z direction. A joint multiple turret is associated with the vertical spindles, this multiple turret being outfitted with tools associated with the two tool spindles. The vertical spindles and the partial slides have separate driving units which can be controlled by corresponding control devices in such a way that the vertical spindles and the partial slides are displaceable jointly and synchronously or asynchronously on the one hand and are displaceable relative to one another on the other hand in order to carry out a correcting adjustment or a feed movement.Type: GrantFiled: April 12, 1996Date of Patent: December 23, 1997Assignee: EMAG-Maschinen Vertriebs- und Service GmbHInventors: Norbert Hessbruggen, Heinz Steinbach

Patent number: 5459915Abstract: The invention relates to improvements in the multiple spindle rotary indexing machine tool systems of the prior art. Traditionally, such machine tool systems include a base and an upstanding vertical column which houses a plurality of machining stations each equipped with two-axis tool slides. In addition, the base supports a rotatable worktable, which carries a number of work-holding spindles. As the worktable rotates, these spindles are indexed through successive machining stations where a variety of operations are performed. In accordance with the invention, a spindle position measurement unit is provided to dynamically measure the exact location of each spindle indexed to position at a modified machining station. A computerized numerical control system calculates spindle position errors based on the position information provided by the measurement unit and offsets tool slide position commands to compensate for those errors.Type: GrantFiled: April 15, 1994Date of Patent: October 24, 1995Assignee: DeVlieg-Bullard, Inc.Inventor: Jesse W.

Patent number: 5097577Abstract: An intermittently rotary workpiece-holding table has operating units that move vertically relative to the table. The operating units are controlled by vertically swinging levers that are driven vertically at one end and at their other ends control the operating units. The levers pivot about fulcrums, each lever having two fulcrums spaced apart along its length. During a first portion of movement of the lever, that fulcrum is operative which gives the most rapid vertical movement to the operating unit. Then the first fulcrum becomes inoperative and the second fulcrum becomes operative, whereupon the speed of vertical movement of the operating unit slows, as for example for the performance of a work operation.Type: GrantFiled: November 30, 1990Date of Patent: March 24, 1992Assignee: Mikron S.A.Inventors: Ugo Buzzi, Giulio Borlin

Patent number: 4642861Abstract: A machine tool has a workholder and an axially aligned toolholder in juxtaposed relation, mounted for relative rotation. A first slide supported for longitudinal reciprocating movement along a "y" axis, supports a cross slide on which a toolholder is mounted for reciprocating crosswise movement to the first slide along an "x" axis. Bell crank motion transmission mechanism on the first slide is interposed between a push bar connected between an NC controlled rotary servo motor and the cross slide, and another NC controlled rotary servo motor is mounted to operate the first slide. Rotary to linear motion translation mechanism couples one servo motor to the first slide and another servo motor to the push bar.

Patent number: 4523359Abstract: A machine has an intermittently rotating table for holding parts to be worked on or assembled. Operating units (20, 21, 25) are actuable either simultaneously for all units or groups of units, or independently of one another. The operating units can be mounted vertically over or under the table and also laterally and can receive the rotary movement of a central wheel or independent motors.
