Composite structure superhard material cutter capable of machining soft and hard metal

Abstract

The invention discloses a composite structure superhard material cutter capable of machining soft and hard metal, which comprises a blade, the blade is provided with a large cutting deep groove, and the large cutting deep groove comprises a first cutting edge, a first negative chamfer, a first front cutter surface, a first transition circular arc and a first anti-chip surface; a blade point is arranged at the included angle of the blade, the blade point is provided with a small cutting deep groove, the small cutting deep groove comprises a second cutting edge, a second negative chamfer, a second front blade face, a second transition arc and a second chip-reversing face, and the second chip-reversing face is connected with the second front blade face; and the small cutting deep groove is used for finish machining of hard metal, the large cutting deep groove does not participate in work when the hard metal material is subjected to small cutting deep machining, the large cutting deep groove is used for rough machining of soft metal, and the small cutting deep groove serves as a blade point to be completely cut into a workpiece. The cutter has the following advantages that soft and hard metal can be machined, the tool changing time is saved, and the application field of super-hard material tools can be expanded; the machining precision is improved; and the tool abrasion is reduced, the machining efficiency is improved, the application field of the superhard material tool is expanded, and huge economic benefits are generated.

Description

technical field [0001] The invention relates to the technical field of cutters, in particular to a composite structure superhard material cutter capable of processing soft and hard metals. Background technique [0002] With the development of metal cutting technology, tool technology is gradually developing towards high efficiency, high precision, and high life. This requires avoiding tool changes during the cutting process, maintaining accuracy and benchmark consistency, and reducing tool wear during the cutting process. It can achieve effective chip breaking and ensure high efficiency, high precision and long life in the cutting process. [0003] Since the actual working position of superhard material blades is only at the tip of the blade when processing hard metal materials, the grooves of some existing superhard material blades are distributed at the tip of the blade. These blades are only suitable for processing hardened steel and superalloys. and other materials. Fo...
