Fine Grinding (Fixed Abrasive) Plates Used on fine grinding machines as a replacement for lapping processes for parts that require high parallelism and close dimensional control. Diameter of plates range from 450mm (17") to over 1000mm (40").
A fine-grit abrasive stone or tape is rotated over the component while the component is simultaneously spun in the opposite direction. This process removes the amorphous surface layer left by the last grinding process and leaves a recognizable crosshatch pattern. Superfinishing will increase the life of a part by decreasing wear and tear.
