PCD (Poly Crystal Diamond) forming cutter

The utility model relates to the technical field of precision machining, in particular to a PCD forming cutter for precision machining. In order to solve the problems that an existing PCD forming cutter is large in production and machining difficulty and low in yield, the PCD forming cutter comprises a cutter body, a front-end cutter frame and a rear-end cutter handle of the cutter body are coaxially connected, a cutting cutter frame is arranged at the most front end of the front-end cutter frame, and a cutting blade is installed on the cutting cutter frame. A chamfering tool rest is arranged in the middle of the front-end tool rest, and a chamfering blade is installed on the chamfering tool rest. A noodle scraping knife rest is arranged at the rear end of the front-end knife rest, and a noodle scraping blade is mounted on the noodle scraping knife rest. The PCD forming cutter is high in production efficiency and yield and low in production cost. 本实用新型涉及精密加工技术领域，尤其涉及一种精密加工用的PCD成型刀。为解决现有的PCD成型刀的生产加工难度大及良品率低的问题
