FIELD: machine building.SUBSTANCE: cutter instrument contains a housing with a working end, to the housing at least one cutting plate and, at least, one base plate are fixed. At least, one base plate is installed on the housing part, joined with it by means of one radial elastic bridge passing in axial direction with reference to the housing, and two tangential elastic bridges passing in axial direction with reference to the housing. Meanwhile in axial direction with reference to the housing the radial bridge and the tangential bridges are separated from the housing by a slot located perpendicularly to the housing centreline.EFFECT: increase of productivity and improvement of quality of processing due to minimising of friction forces between the base plate and processes surface of the hole.4 dwg |
