Abstract
The results of experimental study on the effect of the treatment regime on the shape accuracy of balls and the surface wear of a diamond wheel are presented for the diamond grinding of silicon nitride ceramic balls in an annular groove and with circular feed. The indicators of the shape accuracy of ground balls are the variance of ball diameters, the out-of-roundness profile shape factor, and wheel surface wear characterized by the radial working surface tilt angle and curvature coefficient. This effect is adequately described by the linear dependences of the ball diameter variance on the circular feed rate and wheel speed, the shape factor on the wheel speed, and the tilt angle and curvature coefficient on the circular feed rate. The treatment regime parameters, at which the studied ball grinding scheme is reasonable for application, are predicted.
期刊介绍：
Journal of Superhard Materials presents up-to-date results of basic and applied research on production, properties, and applications of superhard materials and related tools. It publishes the results of fundamental research on physicochemical processes of forming and growth of single-crystal, polycrystalline, and dispersed materials, diamond and diamond-like films; developments of methods for spontaneous and controlled synthesis of superhard materials and methods for static, explosive and epitaxial synthesis. The focus of the journal is large single crystals of synthetic diamonds; elite grinding powders and micron powders of synthetic diamonds and cubic boron nitride; polycrystalline and composite superhard materials based on diamond and cubic boron nitride; diamond and carbide tools for highly efficient metal-working, boring, stone-working, coal mining and geological exploration; articles of ceramic; polishing pastes for high-precision optics; precision lathes for diamond turning; technologies of precise machining of metals, glass, and ceramics. The journal covers all fundamental and technological aspects of synthesis, characterization, properties, devices and applications of these materials. The journal welcomes manuscripts from all countries in the English language.
