The influence of the composition and structure of ferromagnetic composite powders on the surface morphology of hard alloys of titanium-cobalt and tungsten-cobalt groups during magnetic-abrasive processing has been investigated. The mechanisms of contact interaction of a ferro-abrasive quasiplastic medium with the surface of hard alloys are established. Ferromagnetic abrasive powders have been developed for the processing of hard alloys. It is shown that a composite powder clad with silicon carbide and diamond grains has a more intense effect on the surface of hard alloy plates. It increases the intensity of the abrasive component and reduces adhesion during the contact interaction of the powder matrix and the hard alloy. The microhardness of the surface layer of the hard alloy increases by 20-47% relative to the initial one, which is associated with the combined action of the ferromagnetic abrasive powders particles and the magnetic field, which cause deformation of the crystal lattice, an increase in the concentration of dislocations, and refinement of brittle phases.

An important task is to improve cutting tools for high-precision productive machining of difficult-to-machine materials by applying the latest tool hardening methods. This is especially true for carbide-cutting tools. The paper analyzes the current state of the problem of improving the tooling of new machine tools for high-precision productive machining of hard-tomachine materials. The main known methods of increasing the wear resistance and strength of carbide tools can be divided into the following groups: structural methods; mechanical hardening; wearresistant coatings; chemical and thermal treatment; laser hardening; plasma-arc hardening; radiation hardening; ionic alloying; magnetic abrasive treatment; and pulsed magnetic field treatment. The choice of a particular hardening method depends on many factors that determine its effectiveness and costs in certain production conditions. The conditions for machining large-sized parts at heavy engineering enterprises are analyzed. It was found that, along with wear, the destruction of the cutting part in the form of pitting and fracture is significant. Statistical studies have proven that when machining on heavy machine tools, the cutting force allowed by the machine tool mechanisms does not limit the cutting modes. The maximumvalues of forces are up to 10 times higher than their average value, which is usually used to calculate the design parameters of cutting tools An analysis of various methods for improving the physical and mechanical properties of carbide tool materials has shown that the best combination of cost and production efficiency is observed in pulsed magnetic field treatment. The use of magnetic fields in cutting processes and tool hardening is a promising area of high-technology development in machining. Increasing tool life can be achieved by the influence of a magnetic field either on the conditions of the cutting process or on the structure and physical and mechanical properties of tool materials with ferromagnetic components.

The concept “structural strength of tool materials” got further development. The refusals of cemented carbide cutting plates, when heavy machining were analyzed. It was shown that 70…80% of refusals are the microchipping of cutting edges, tool cutting part chipping, cutting plate macrofracture. To assess cutting plate total carrying capacity and the influence of different methods of cemented carbides modification, bending tests were held. Local fracture resistance and damageability of cutting edge were assessed under its continuous scanning.
