Method for grinding metallic workpieces containing, in particular, nickel

Abstract

The invention relates to a method for grinding metallic workpieces containing, in particular, nickel, whereby a rotationally driven grinding wheel ( 2 ) is continuously dressed by a rotationally driven dressing wheel ( 3 ) during the grinding of the workpiece ( 1 ) by the continual advance (vfrd) of the dressing wheel. In order to increase the grinding capacity, the invention provides that with a dressing advance velocity of 1 to 2 μm per rotation of the grinding wheel and with a circumferential velocity of the grinding wheel (vs) of at least 45 m/s, the advance (table velocity vt) is set such that the rate of metal removal is at least 90 mm 3 /mms.

1 . A method for grinding in particular nickel-containing metallic workpieces, in which a grinding wheel ( 2 ), which is driven in rotation, is continuously dressed by a dressing wheel ( 3 ), which is driven in rotation, during the grinding of the workpiece ( 1 ) by means of a continuous infeed (vfrd) of the dressing wheel, characterized in that, at a dressing infeed rate of 1 to 2 μm per revolution of the grinding wheel and a circumferential speed of the grinding wheel (vs) of at least 45 m/s, the advance (table speed vt) is set in such a way that the material-removal rate is at least 90 mm 3 /mms.  
     
     
         2 . The method according to one or more of the preceding claims or in particular according thereto, characterized by a highly porous grinding wheel, in particular comprising 50% by volume of air.  
     
     
         3 . The method according to one or more of the preceding claims or in particular according thereto, characterized by a grinding-wheel speed of revolution of more than 50 m/s, preferably more than 60 m/s, and an advance which corresponds to a material-removal rate of more than 100 mm 3 /mms or more than 150 mm 3 /mms.
