In developed countries, material scientists are working intensively to create high-strength (metallic) technical ceramics. If such a material is created, it will be possible to manufacture such parts of power units (transmissions) of cars as shafts, turbines, etc. In the future, the latest composite ceramic materials with unique properties will gradually replace metals in the production of machine parts. Special device for diamond grinding of articles from composite, non-metallic, brittle materials (technical ceramics on the base of SiC, Al2O3; polycrystalline diamond, composite – Si + SiC + diamond etc.) is a universal flat grinding machine that enables to grind with high productivity both supporting main surfaces and lateral side surfaces – perimeter of an article of prismatic shape. It is also possible to grind substrates of other configurations – round, oval, etc. Grinding depending on sizes of articles can be done of both single and group of articles. The grinding takes place by the means of spring feeding of the article by pneumatic system that enables to prevent breakage of articles from brittle non-metallic materials in process of machining and obtain maximum high quality of the machined surface.
