MECHANISM FOR IMPROVED TWO-WAY ACCURATE ADJUSTMENT OF CUTTING INSERT CASSETTES IN PROCESSING CUTTING TOOLS Russian patent published in 2019 - IPC B23B29/00 

FIELD: turning equipment.

SUBSTANCE: cassette for cutting plate for machining cutting tools that remove chips has a system of axial adjustment interacting along the thread with cassette housing and cutting tool casing. Axial adjustment system includes a differential screw in engagement by thread with the cutting tool body either directly, for example by means of thread interaction with the threaded hole in the cutting tool body, or indirectly, for example by means of interaction with a transverse fastening pin with the possibility of sliding in the hole in the body of the cutting tool. Drive section located in axial direction between threaded end sections of differential screw has engaging element on outer surface, which is configured to be actuated, for example by means of a tool or a hand, to turn the differential screw and to adjust the axial position of the cartridge. Spaced arrangement improves access to drive section and engaging element for rotation of differential screw. Also described are machining-cutting tools with similar cassettes and machining methods.

EFFECT: disclosed is a mechanism for improved two-way accurate adjustment of cutting insert cassettes in processing cutting tools.
