CUTTER WITH THE CUTTING PLATE MECHANICAL MOUNTING Russian patent published in 2018 - IPC B23B27/16 

FIELD: manufacturing technology.

SUBSTANCE: cutter includes holder with seat, support plate, cutting insert, wedge-clamp, wedge-clamp securing screw and adjacent to the seat basing surfaces located parallel to the cutting insert main and auxiliary rear surfaces with the possibility of close contact with them. Cutter is provided with mounting elements, on which the said basing surfaces are located, and the wedge washer located between the screw head and the wedge-clamp, at that, in the holder the threaded holes are made for the mounting elements fastening, and the angle of inclination α between the wedge washer and the wedge-clamp bearing surfaces is selected according to the given formula, depending on the friction at rest coefficients between the wedge washer and the wedge-clamp surfaces; between the wedge-clamp and the cutter holder surfaces and between the cutting and supporting plates surfaces.

EFFECT: enabling reduction in the tool adjustment size error during the indelible plate turning or replacing and reducing the tuning time losses.
