Abstract
1488746 Grinding NEWALL ENG CO Ltd 11 May 1976 [4 July 1975] 28349/75 Addition to 1327894 Heading B3D A machine for grinding a workpiece 1 having a first cylindrical surface 2, comprises means 5 for grinding a second surface 4 to a desired contour coaxial to the first surface, a relatively stationary mandrel 3 having passageways 7, 8 coupled to a pneumatic source for feeding and maintaining a gas bearing between the mandrel and the first surface, and means for rotating the workpiece comprising a rotary face plate 9 supported for rotation on the mandrel on a further gas bearing fed by passageways 13, 23, the further gas bearing including two opposed axial thrust bearings 20, 21 one on each side of a radial flange 22 on the face plate, means 27, 28, 29 for rotating the face plate, and a clamp 14 operable by pneumatic pressure to clamp the workpiece against the face plate for rotation therewith. As described, the workpiece 1 is a bearing ring rotatably mounted with its inner cylindrical surface 6 supported on the mandrel surface 2 by a gas bearing supplied with pneumatic pressure through passageways 7, 8. The face plate 9 is rotatably supported on a second cylindrical surface 11 on the mandrel by a second gas bearing supplied with pneumatic pressure through passageways 13. The radial flange 22 of the face plate extends between radial flanges 3a, 3b of the mandrel and its opposed axial thrust bearings 20, 21 are supplied with pneumatic pressure by passageways 23. The workpiece is clamped to the face plate for rotation therewith by a clamp ring 14 mounted on an annular piston 15 which is located in a cylinder and journalled for rotation on a member 19. Rotation of the face plate is effected by a peg 27 engaging a hole 28 in the face plate and carried by a member 29 rotatably driven about the axis of the mandrel. Permanent magnets may be provided on the clamp ring 14 to draw the workpiece from the mandrel when the piston and clamp ring are retracted during unloading of the workpiece.
