FIELD: mechanical engineering.
SUBSTANCE: grinding machine tool comprises housing and diamond abrasion segments mounted on the housing by means of fastening members. The housing is provided with T-shaped radial grooves made on its face and central longitudinal and threaded openings. The fastening members are made of blocks set in the grooves of the housing for permitting radial movement. The cross-section of the blocks is shaped so that to be mating to the block groove. The inner face of the blocks is inclined at an acute angle. The blocks are provided with radial and peripheral plates for receiving radial and peripheral segments. The ring expansion spring is mounted from the free end of the housing. The central longitudinal opening receives the plunger whose outer side cooperates with the inner face of the blocks.
EFFECT: expanded functional capabilities.
