METALLIC BOND FOR MANUFACTURE OF THE SEGMENTS ON THE BASIS OF THE SUPERHARD MATERIALS FOR PRODUCTION OF THE CUTTING TOOLS AND THE METHOD OF THE CUTTING TOOLS MANUFACTURE Russian patent published in 2007 - IPC B24D3/06 B24D18/00 

FIELD: chemical industry; mechanical engineering; other industries; universal block mold used for reprocessing the polymeric materials.

SUBSTANCE: the invention is pertaining to manufacture of the abrasive cutting tools, for example, the cutting wheels of the large diameter. For manufacture of the segments on the basis of the superhard materials use the metallic bond containing chromium carbide, copper, stannous, titanium, boron, aluminum, titanium hydride and cobalt at the following ratio of the components (in mass %): chromium carbide - 5-10, copper - 15-20, stannous - 1.5-2, titanium - 4-6, boron - 1-3, aluminum - 1-2, titanium hydride - 1-2, cobalt - the rest. The charge of the metallic bond with the powder of the superhard materials is loaded in the press-mold and subjected to molding. At that the loading is conducted in the following succession: the loading of the charge of the powder of the soldering alloy with the subsequent manual prepressing of the soldering alloy layer, the loading of the charge of the metallic bond and the loading of the charge of the metallic bond with the powder of the superhard materials. A s a result of it the invention ensures simplification of the production process of the manufacture of the segments on the basis of the superhard materials for production of the cutting tools at the simultaneous improvement of the cutting power of the manufactured tools.

EFFECT: the invention ensures simplification of the production process of the manufacture of the segments on the basis of the superhard materials for production of the cutting tools at the simultaneous improvement of the cutting power of the manufactured tools.
