Document Type and Number:
WIPO Patent Application WO/2021/197215
Kind Code:
A1
Abstract:
Disclosed is a blank body. The blank body is made of a superhard material and used for being fixed to a base body (200) and may be machined to form a cutter cutting edge part (310), and comprises a first side face (100) and a second side face (120), each of which is twisted at a set helix angle. After the blank body is fixed to the base body, the blank body is machined to form a main cutting edge (320) and the central cutting edge (310), which are used for cutting and are located on the same blank body made of the superhard material. Further disclosed is a cutting tool comprising the blank body. The machining tool is provided with a continuous and complete central cutting edge (310) made of the superhard material at the center of revolution, such that not only are the machining precision and the machining efficiency improved, the strength of the center is also improved, the service life is prolonged in the cutting process, and the overall cutting performance of the cutting tool is significantly improved.
