Profile grinding is employed to grind various precision moulds such as die & punch for press which have complicated forms of irregular lines and curves, forming cutting tools, cutting tools, high precision plate gauge, electrode for electric discharge grinding and formed precision parts such as template. Structually profile grinding wheels are used in dry which is a big feature and handled by manual system as well as Numerical Control full automatic system. Lately NC machines are widely employed in various industries and increasing rapidly. Rigidity , horsepower and machining accuracy of latest machines have been much improved where profile grinding wheels are required more under this condition to generate high precision machining.
