Abstract

1429202 Centreless grinding KOENIG & BAUER AG 19 Oct 1973 3 [19 Oct 1972] 48905/73 Heading B3D A centreless grinding machine for plungecut grinding comprises a regulating wheel 9 disposed in horizontal juxtaposed relation to a grinding wheel 4, a work-supporting blade 7 disposed between the wheels, means for locking the blade relative to the grinding wheel while the regulating wheel is fed towards the grinding wheel during grinding, and means for moving the regulating wheel and the blade in unison towards the grinding wheel to compensate for reduction in diameter of the grinding wheel due to wear. The grinding wheel 4 is carried by a bracket of the machine bed 1 which has a pivot 3 for a swivel slide 5 adjustable by a screw 10. An intermediate slide 5 supports the work-supporting blade 7 and a spindle head 6 for the regulating wheel 6. A threaded spindle 12 is secured to the intermediate slide 5 and has a threaded bush 13 engaged by a worm-wheel 11 driven by a servo motor, the bush and worm-wheel being mounted in a housing 2.1 on the swivel slide 2. A threaded spindle 14 is mounted in the intermediate slide 5 for rotation but is axially fixed and has a threaded member 16 engaging a helical gear 17 rotatable in the headstock 6 by a lockable handwheel 18 which effects a coarse adjustment of the regulating wheel by rolling the gear 17 along the member 16. With the handwheel 18 locked, the regulating wheel is fed towards the grinding wheel by rotation of the spindle 14 and member 16 by a rotary piston 15. When wear of the grinding wheel is detected, the gear 11 is turned by its servo-motor to move the intermediate slide so that both the blade 7 and regulating wheel are adjusted in unison.
