Embodiment Construction

[0009] The device for grinding a workpiece 1 comprises a grinding wheel 2 which is continuously driven in rotation and is operated at a rotational speed at which the grinding wheel acts on the workpiece 1 at a grinding speed vs. The direction of rotation is indicated by arrow 2'.

[0010] The grinding wheel 2 is continuously corrected by the correcting wheel 3, which moves in the same direction 3' and can be moved in the direction of the arrow 3''. The speed of the dressing wheel is about 80% of the speed of the grinding wheel. In order to achieve the purpose of grinding, the circumferential surface of the grinding wheel 2 is e Cutting into a workpiece 1, the workpiece 1 is placed on a movable table 4, which moves at a speed vt in the direction indicated by the arrow 4'.

[0011] Grinding wheels consist of porous materials. 25% of the volume of the grinding wheel is formed by abrasive grains, 15% is formed by binder, and 50% of the volume is air. This is a porous grinding ...

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 mum 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.

Description

technical field [0001] The invention relates to a method for grinding metal workpieces, in particular containing nickel, wherein, during the grinding of the workpiece, the grinding wheel is continuously corrected by a correcting grinding wheel, which is achieved by continuously feeding the correcting grinding wheel, dressing the grinding wheel and the grinding wheel are driven to rotate. Background technique [0002] This type of method is known in the prior art as CD grinding. Continuous correction of the grinding wheel means that the grinding wheel always maintains its shape. However, the disadvantage of this method is that the consumption of the grinding wheel is very large. The amount of grinding, i.e. the material removal rate, depends on the table speed. In the prior art, the table speed is set so that the material removal rate is less than 30mm 3 / mms. In the prior art, the speed of the correcting grinding wheel is less than 1 μm / revolution relative to the grindi...
