DISCRETE INSTRUMENT FOR COMBINED GRINDING Russian patent published in 2018 - IPC B24D5/14 

FIELD: technological processes.

SUBSTANCE: invention relates to the field of abrasive processing and can be used for simultaneous preliminary and final grinding of products on one machine. Tool contains coarse-grained and fine-grained grinding wheels mounted on a single spindle and an annular gasket located between them. Grinding wheels of the tool are discrete, and in the body of each of them, radial holes are made on the cutting surface side by means of a highly concentrated energy flow, the number of which in a coarse-grained grinding wheel is smaller, and their diameter is larger than in a fine-grained wheel.

EFFECT: as a result, the thermal intensity of the processing process and the level of vibration of the spindle are reduced.
