FIELD: technological processes.
SUBSTANCE: invention relates to the field of abrasive treatment and may be used for relief grinding of cutter teeth of cutting tool, such as tap or thread cutter. Additional radial turning inside motion is imparted to grinding disk in concord with rotation of adjustment disk. The latter has adjustment contour, such as supplemental curve, corresponding to highest number of possible relieving contours. A section is selected with limited specified angle range on adjustment disk, and oscillating rotary motion is imparted to disk within specified angle range. This section of disk is copied by means of copying mechanism, and result is transmitted along signal wire to control device to adjust motions of grinding disk and processed cutting tool.
EFFECT: increased efficiency of grinding due to provision of low inertial adjustment when arranging various relieving contours and eliminating replacement of high-accurate elements of grinding process control.
