Abstract
The results of an experimental study of the effect of the processing mode on the wear of the diamond wheel surface and the accuracy of the ball shapes are described for diamond grinding of ceramic balls made of silicon nitride with a circular feed. The angle of inclination of the working surface in the radial direction, the curvature coefficient, and the accuracy of the shape of the polished balls, i.e., the instability of the ball diameter and the form factor of the round profilogram, are taken as wear indices of the wheel surface. The observed effects are described by adequate linear dependences of the angle of inclination and the curvature coefficient on the frequency of feeding the workpieces, the instability of the ball diameter on the wheel rotation frequency, and the form factor on both parameters. Combinations of the processing mode parameters within the studied range of changes are determined, which served as a basis for the subsequent optimization of the indicated parameter values.
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.
