【 摘 要 】

Objective: Difficult-to-cut materials are the mainstream of the current machining research. The purpose of the study is to apply high speed deep hole drilling technology to difficult-to-cut materials, but ordinary high-speed drilling technology can not deal with problems of difficult-to-cut materials in the field of processing. Materials and Method: The study starts with multi-edge BTA deep hole drilling for its greatest advantage in cutting TC4 - the most typical difficult-to-cut materials. This paper proposes a viewpoint for reducing the friction force of the guide block so as to improve the cutting speed. Results: By means of testing, the author obtains the function relation between the tooth width of drilling bits and the force in cutting titanium alloy and redesigns the width and position of the high-speed deep-hole drilling bit, completing the cutting tooth material and the geometric angle of the cutting tooth. Conclusion: He verifies the viewpoint and optimizes the parameters of the drilling bit. These provide the theoretical basis for the design of high-speed deep-hole drilling bits.
