Abstract
PURPOSE:To eliminate the generation of dynamic pressure in a final grinding condition and a profile error by supplying a coolant of small amount in a grinding condition that a grinding wheel is fed in a slow speed for a cam. CONSTITUTION:In a grinding cycle, during a feed of rough grinding, accurate grinding and fine grinding, setting the opening of a flow control valve 13 to a large degree by a control unit 14, a coolant of large amount is supplied from a nozzle 10. As the result, in a grinding period, that is, in the initial period grinding condition wherein a grinding wheel G is fed in a fast speed for a cam W, a grinding burning and a grinding crack can be prevented, and the cam W can be ground in high efficiency further with a high peripheral speed. Next in a grinding condition with the grinding wheel G in a slow feed speed or during spark out grinding, the opening of the valve 13 is set to a small degree, and the coolant of small amount is supplied from the nozzle 10. As the result, generating no dynamic pressure by the coolant between the cam W and the grinding wheel G, the cam W is prevented from generating profile error.
