Abstract

1336354 Truing control FORTUNAWERKE MASCRINENFABRIK AG 3 Sept 1971 [5 Sept 1970] 41163/71 Heading B3D [Also in Division F2] A grinding machine includes an arrangement for feeding a truing device 18 and means coupled to a positioning device 12 for a guard 9 for covering the grinding wheel 4 so that the guard 9 may be adjusted according to the diameter of the wheel 4 synchronously with truing. In a cylindrical grinding machine with a grinding spindle 2, a truing tool carrier 19a may be positioned and fed by a fluid-pressure operated rapid feed device 21 and a fine feed device comprising a nut 22b on a threaded spindle 22a, arranged to be driven through a gear connection 24, 25 from a pawl gear 23. The guard 9 is supported by a nut 13a on a screwed spindle 13. The spindle 13 may be driven in unison with the feed spindle 22a through a clutch connection 12b to the gear connection 24, 25, or by a second pawl gear controlled with the first 23 by a common control device 28. The guard 9 is supported for horizontal movement by means of a pin 32 on a fixed hood 8, the pin 32 entering a slot 31, and a tapered portion 33 of the slot 32 is provided to co-operate with the pin 32 in dissipating energy if the guard should be forced out of position, e.g. by grinding wheel breakage. A coolant delivery pipe 9b is preferably provided on the guard 9.
