METHOD FOR GRINDING disposable plates (Options) and grinding wheel for performing the method

摘要

In an indexable insert having the wide sides 10a, 10b, the inclined narrow sides 24 are to be ground, that is to say the grinding allowance 38 is to be removed. To this end, the indexable insert 10 is set in rotation about the driven axis of rotation 11 (C axis) between a clamping insert 6 and a thrust bolt 9. Serving for the grinding is a grinding wheel 18 which rotates about the rotation axis 19 and which has a circumferential surface 18a contoured in a circular shape and having the largest diameter 43 and is composed of a leading region 41 and a trailing region 42. The grinding wheel 18 is guided relative to the indexable insert 10 along the geometrical defining line 39 which is formed by the generating line of the finished narrow side 24 in the feed direction 44. The leading region 41 tapering forwards effects preliminary grinding of the narrow side 24 by longitudinal grinding, whereas the trailing region 42 effects finish grinding by linear contact with the narrow side 24. The grinding wheel 18 is held with the clamping flanges 40 on a grinding spindle. The grinding operation is effected with controlled movement of the driven axis of rotation 11 (C axis), a first displacement axis 3 (Z axis), a second displacement axis 15 (X axis) and a pivoting movement of the grinding wheel 18 relative to the indexable insert 10 according to double arrow B.
