  • Patent number: 4858387
    Abstract: A wheel slide 20 for supporting a grinding wheel 40 is mounted on a carraige 100 which extends across a work area to engaged parallel horizontal ways 61, 62 on opposite sides of the axis of rotation B of a workpiece W. The carriage 100 has ways 114, 115, 116 which support the wheel slide 20 for vertical movement toward and away from a horizontal axis B of rotation of the workpiece.
    Type: Grant
    Filed: October 30, 1986
    Date of Patent: August 22, 1989

  • Patent number: 4831782
    Abstract: An improved grinding apparatus includes a base (100) upon which a headstock (20) is mounted. A carriage (500) is movable along ways (101, 102) disposed on the base. A wheel slide (63) on the carriage rotatably support a grinding wheel (71). A first mounting plate (80) extends beneath a first footstock (400) and a first set of steadyrests (300) to a location adjacent to a headstock (20). While a workpiece is being ground, a second set of steadyrests (300) and a second footstock (400) are mounted on a second mounting plate (80). When the grinding operation has been completed, the first mounting plate is disconnected from the base (100) and removed from the grinding apparatus with the first set of steadyrests (300) and footstock (400). The second mounting plate (80) with the second set of steadyrests (300) and footstock (400) accurately positioned thereon are then inserted into the grinding apparatus.

  • Patent number: 4754574
    Abstract: An improved apparatus for grinding a workpiece (W) includes a base (10) upon which a headstock (21) and a tailstock (23) are mounted to support a workpiece for rotation about axis (A). A carriage (300) is movable along the base. A light weight wheel slide (400) is mounted on the carriage and is movable toward and away from the workpiece. A grinding wheel (501) is rotatably supported on the wheel slide. In order to provide a solid support for the light weight wheel slide, the carriage has a plurality of guideways (901, 902, 903) which are enclosed by the carriage. The carriage extends throughout the length of the guideways and provides a solid support for the guideways.

  • Patent number: 4726103
    Abstract: A fixture (50) is used to precisely locate the horizontal (20, 30) and vertical (10) guideways on the bed (40) of a grinding machine. After locating the guideways (10, 20, 30), a bonding material (70) is placed in the spaces (1, 2, 3) between the guideways (10, 20, 30) and grinding machine bed (40). After the fixture (50) is removed, bolts (80) are tightened to apply a compressive force on the bonding material (70) located between the vertical guideway (10) and the machine tool bed (40).
