Abstract
The utility model discloses a polycrystalline cubic boron nitride (PCBN) cutter for machining cylinder bodies, which comprises a blade and a cutter body. The blade and the cutter body are combined together in a vacuum silver welding mode. The cutter body is provided with positioning holes. The positioning holes are composed of two holes, namely a large hole and small hole, for realizing the positioning effect. The two holes are positioned in a circular arc transition with respect to each other. The periphery of the cutter body is provided with relief angles respectively. Especially, the cutting edge of the blade is provided with a chamfering transition. According to the technical scheme of the utility model, the cutting edge of the blade of the cutter is provided with a chamfering transition. Due to the adoption of the PCBN cutter for machining cylinder bodies, the cutting resistance of the cutting edge of the blade is effectively reduced, while both the machining efficiency and the surface quality of workpieces are improved. Meanwhile, the machining cycle is shortened and the machining cost is lowered.
