SYSTEMIn the paper is analyzed the dynamics of a movable block, consist of two boring tool with oppositely positioned cutting inserts, applied as a cutting part of tools for combined machining of deep holes by cutting and surface plastic deformation. Tribo-mechanical and force dependencies were derived, connecting the geometry of the cutting inserts and the friction forces in the contact surfaces of the block with its working capacity.
