Rekord 500 CNC

CNC Grinding Machine For Metal Cutting Circular Saws.

This CNC grinding machine is suitable for re-sharpening or manufacturing of HSS, friction, and solid carbide circular saw blades. The grinding can be effectuated using emulsion or neat oil coolant. Using CBN or diamond grinding wheels guarantees outstanding quality of finish and precision with short cycle times. The machine uses the latest computer technology to guide the operator through simple and easily programmable menu driven display.
