Abstract

1322211 Grinding N SCHLUMBERGER & CIE 14 July 1970 [17 July 1969] 34191/70 Heading B3D A drill grinding machine comprises a grinding wheel 1 carried by a spindle 3 rotatably mounted off-centre in a sleeve 4 which is rotatable and axially movable, the axial movement being controlled by a stationary annular cam 37 engaging a roller 38 carried by the sleeve on a radial axis, and the cam having a major portion axially displaceable by position-adjustment means 45. The spindle 3 is mounted off-centre in tapered roller bearings 11, 12 in the sleeve and is rotated by a belt-driven pulley 24, and the sleeve is mounted for rotation and axial movement in needle roller bearings 31, 32 in a frame 5. Rotation of the sleeve is effected by a gear 36, and the axial movement is effected by the cam 37, which is of annular shape and roller 38 so that the grinding wheel is moved to helically grind the point of a drill. The roller is mounted on a pin 56 extending from the sleeve, and the cam has a portion which is secured by screws 42, Fig. 4, to the frame and connected by slots 51, 52 permitting deformation of an operative segment of the cam which is engaged by the roller, a spring 67, Fig. 2, acting through a pivoted lever 64 to press the roller against the cam. In order to adjust the cam, a screw 45 is rotated to displace the segment via the slots 51, 52 relative to the position fixed by the screws. In other embodiments, the cam is not deformable but is mounted for adjustment about the axis of a rod secured to the cam.
