Cutting Unit, Method Of Varying Rake Angle Of Cutting Unit And Method Of Assembling Thereof
Abstract: The cutting unit consists of detachable head assembly with a cutting insert and holder. The mating spherical surfaces in both parts helps to get freedom of movement, hence helps in getting different rake angles. A set of pins helps getting correct center height for the cutting insert when spherical surfaces of both parts are not in contact with each other. The pins when lifted up gives point contact with spherical surface of the head assembly. The pins are moved in the holes provided in the holder with the help of screw-nut principle. The head assembly is clamped against holder using clamping ball mechanism. The clamping balls are free to rotate in their respective seating area. Rakes are changed by turning the head assembly manually. Once the required rake is set, the clamping balls are fastened. Thus providing an option to vary rake angle in the cutting unit.
