Perfect Balance in Diamond Tooling

1. ” Efficiency of tools from diamond and cBN : The compromise of contradictory trends ” Quality of the generated surfaces Durability Productivity - The contribution of productivity, durability and quality of a surface to an end result Perfect balance Real situation - Problems and losses = not used possibilities Raise of durability of the tool on 30 % yields 1 % of economy of the cost price, Productivity raise on 20 % yields 10-13 % of economy of the cost price of process of machining The potential performance level of the up-to-date grinding equipment, as a rule, surpasses the level of possibilities given by the tool. The disbalance parent - extreme character of the physicochemical processes in a band of dynamic contact of the instrumental and handled materials. . Productivity Quality of the generated surfaces Durability

3. Demands of high efficiency and high durability clash, forming "vicious circle". Nevertheless, High durability is dictated by demands of the up-to-date equipment; shape retention of an effective surface of the tool directly influences accuracy of geometry and a state of a surface of finished parts Allocation of internal stresses in surface layer of H10F cemented carbide Tool adaptability results in better durability of sharpened hard alloy cutter Effect of productivity of grinding on ultimate bending strength of samples H10F cemented carbide Evolution of t he shape of a profile of an abrasive wheel from traditional abrasive composite in process of grinding Evolution of t he shape of a profile of an abrasive wheel from adaptable abrasive composite in process of grinding Abrasive composite adaptability minimizes the distortion of handled material structure Effect of productivity of grinding on sizes of blocks of a mosaic and magnitude of distortions of a crystal lattice of grains of tungsten carbide Compression tension raise fatigue strength of a material

4. Self-tuning of microgeometry of the adaptable grinding tool cutting profile Deforming abrasive grain Basic curve surfaces of the gas distribution valve of the engine after grinding: 1, 2 - a traditional cBN composite, 3 , 4 - adaptable cBN composites Resource of operation of gas distribution valve on the relative basic area at level of 2 microns 1, 2 - a traditional cBN composite, 3 , 4 - adaptable cBN composites Cutting abrasive grain Isolines of mechanical stress, caused by adaptive structural transform
