DAMPER CUTTER WITH ADJUSTED STIFFNESS Russian patent published in 2013 - IPC B23B27/00 

FIELD: process engineering.

SUBSTANCE: proposed cutter comprises cutting plate with its mounts in holder with recess. Said recess shapes said holder surface to cylinder extending from its end to cutting plate. Cylindrical end of said holder is arranged in closed elastic shell made from vulcanised material shaped to barrel with communicated walls and bottom provided with cylindrical union at its outer wall. Note here that barrel ID and its height equal holder diameter and cylindrical section length. Note here that barrel with holder is fitted with clearance in cylindrical metal container with through hole in its bottom, its diameter exceeding that of said barrel, and two parallel flats located at diametrically opposite sides of container outer surface. Note here that compressed air is forced via said union into barrel bottom and walls to fill the clearance between container and holder and to create surplus pressure that allows making integral mechanical system "holder-barrel with compressed air forced therein-container.

EFFECT: higher firmness.
