Semiautomatic 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 flatly grinding machine that enables to machine with high productivity both backup – basic surfaces and side surfaces – perimeter of the article of prismatic shape. Machining depending on sizes of articles can be done of both single and group of articles. The machining takes place by 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.
The “Low temperature precision grinding” (LPG) method is characterized by relatively low speeds of grinding (6…10 m/sec), low thickness of shearing (to 0,1…0,001 μm)
