Abstract: The process for securing a machine tool bed to a base includes the steps of providing a base having a horizontally disposed first surface wherein a plurality of cooperating grooves are disposed. A selected quantity of hardenable grout material is deposited into the grooves. A bed has a second surface from which a plurality of tongues extend, and each tongue has side surfaces which are relatively rougher than the associated distal surface. The bed is horizontally positioned above the base so that each tongue is received in an associated groove and each distal surface is spaced from the associated underlying groove, thereby causing the grout material to rise by an amount insufficient to contact the second surface. The bed is maintained spaced above the base until the grout material has hardened and thereby binds each side surface but not the associated distal surface to the base.

Abstract: This invention pertains to a head stock assembly for a chucker and bar machine which includes a special bearing system comprising three forward bearings and two rearward bearings for providing five point contacts to the spindle for maintaining stiffness and rigidity and improved accuracy in machining. It also includes cooling fin means for dissipating the heat about the bearings which would normally build up in a headstock after long periods of operation. The heat dissipation reduces growth of the headstock and therefore improves accuracy. In addition, the headstock assembly has mounted directly thereon a spindle encoder, a brake disc, a collet closer mechanism, a balancing disc, as well as a low pressure means for preventing cutting fluids and dust and dirt from entering into the bearing mechanism.

Abstract: A compound turret for machine tools such as latches or the like having rotating and non-rotating tooling turrets mounted on a single housing. The compound turret includes a primary drive and a secondary drive. The primary drive includes a compound turret indexing unit operable to index the rotating and non-rotating tooling turrets into the turret operating and turret storage positions. The compound turret indexing unit consists of a harmonic drive that enables the operator to incrementally vary the turret operating position. The harmonic drive achieves high reduction ratios in a single stage thus eliminating the cumbersome gear systems usually implemented to achieve the reduction ratios required. The primary drive further includes a non-rotating tool indexing unit. The non-rotating tool indexing unit is operable to index the non-rotating tooling. The non-rotating tool indexing unit consists of a harmonic drive unit similar to the compound turret indexing unit.

Abstract: An indexable machine tool turret comprising a body having a chamber, an opened end, a closed end and a central longitudinal axis; an axially displaceable rotatable turret top plate having a number of angularly spaced apertures for holding tools, said top plate being co-axial with said body axis; an axially displaceable and extending rotatable shaft connected to said top plate, said shaft co-axial with said top plate; two opposed annular face gears for seating said top plate to said body, said gears co-axial with and concentric with said top plate, one of said gears mounted in said top plate for engaging said other gear, said other gear mounted in said body; said shaft including a ring gear mounted concentrically thereto; means for displacing said shaft and thereby said top plate for causing said face gears to engage and disengage; drive means for engaging said ring gear for rotating said shaft when said face gears are disengaged; cushioned stopping means for stopping said shaft rotation; and, angular rotation

Abstract: A two slide multiple axis machine comprising a machine tool bed having at least two parallel, spaced apart, longitudinal ways; a spindle mount fixedly attached to the bed; a rotateable spindle mounted in the spindle mount at a distance from the bed and having an axis of rotation parallel to the axis of the ways and adapted for receiving and detachably holding a work piece; first tool means engageable with said work piece and displaceably mounted for forward and rearward motion in the first of said ways parallel to the longitudinal axis of said ways; second tool means engageable with said work piece and displaceably mounted for forward and rearward motion in the second of said ways; first way cover means covering the first of said ways and fixedly attached to said first tool means and adapted for movement with said first tool means; and, second way cover means fixedly attached to said second tool means and adapted for movement with said second tool means is disclosed.

Abstract: A bed for a machine tool comprising a bottom, sides, a front, a rear and top with the bottom having a three point suspension and the top having a substantial portion inclined at between 55.degree. and 65.degree. from the horizontal and including a pair of spaced cavities within the bed which are ribbed and provide dual torque tube reinforcement.

Abstract: A multi jaw rotary chuck for lathes and the like comprising a body having front and rear portions and including a bore, a plurality of spaced jaw guides in the front portion of the body, a plurality of movable master jaw supports for the jaws of the chuck, the jaw guides each having one of the master supports slideably guided thereby, a plurality of actuator plates in the body each mounted in spaced radial planes intersecting and parallel to the axis of the bore and each actuator plate having first, second and third apexes, the first apex of the plate having a hole and including a first dowel pin mounted in the hole and extending outwardly on either side thereof transverse to the plane of the respective plate, the second apex of each plate having a hole and including a second dowel pin mounted in the hole and extending outwardly on either side thereof transverse to the plane of its respective plate and generally parallel to the first dowel pin, pivot means on each of the actuator plates journalled in the body

Abstract: A multiple work station machine tool turret has a highly responsive sensing control assembly which is free of environmental constraints and provides a distinct signal for each work station position correlatable with work station command data from a programmer.

Abstract: A turret index assembly has an air piston connected to a pawl to provide a cushioned stop therefor after its engagement with one of the teeth of a machine tool turret index plate.

Abstract: In a turning machine or the like having a tool for simultaneous axial and radial profiling of work, that invention which includes a rotatable spindle having a forward end and work support means on the forward end, circumferential profiling means rotatably mounted on the spindle and a carriage support mounted on the machine adjacent the spindle, a movable tool support carrier on the carriage support movable in a direction generally parallel to the spindle axis, a tool holder mounted in the tool support carrier for movement parallel to and radially of said spindle axis and the tool holder including longitudinal profiling means and including tracking means mounted between the circumferential profiling means and the longitudinal profiling means for simultaneously tracking both of the profiling means.
