ABRASIVE WHEEL Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: cutting circle is made in the form of integral multilayer housing consisting of monolayers made of unidirectional difficulty fusible threads, for example, boron, disposed in metallic bundle with high thermal conductivity not less than 600 C, aluminium, for example. The monolayers of unidirectional threads of housing are unfolded relative to each other around its axis in the plane of placing at the value of angle 180 deg/n, where n - number of monolayers. The cutting edge of cutting circle is formed at the expense of unidirectional difficulty fusible threads projecting along face surface of cutting circle by the value not more than 0.15 mm. EFFECT: enhanced strength, resistance to wear, size stability and rectilinearity of cut during exploitation, excluded "wedging" and "greasing" of the tool, facilitated manufacture. 7 dwg
