In this paper, with deep hole machining titanium alloy tube as the research object, research on titanium alloy pipe deep hole processing technology, in the company, according to the company's existing equipment ability, in the original T2120 transformation on the basis of the deep hole processing equipment, to study design of a dedicated tool rod long; Also developed a series of special deep hole machining tool and related tools, using traditional deep hole (enlarge hinge) processing technology, to realize the deep hole processing technology of titanium alloy, overcome the titanium alloy in the process of test development of the deep hole processing a variety of difficulties, to solve the many key technology, meet the requirement of deep hole machining technology, and completed the titanium alloy tube deep hole processing; Achieved the late development goal. The development and matching requirements are guaranteed, and the obvious effect is obtained.
With the development of manufacturing technology in our country, in the process of production of some typical components, has a high degree of technical content, its processing and manufacturing have considerable difficulty, need to adopt some new methods and new technology, but also need the development and utilization of the traditional processing technology advantages, process research.
Pipe pieces of material for Tc6 titanium alloy, the pipe hole diameter for Φ 40, length of 575, as shown in figure 1, the titanium alloy material of deep hole processing technology is the first time we come into contact with the deep hole processing, deep hole similar to typical long axial parts hollow structure, especially the inner hole diameter dimension for Φ 40 deep hole; The company's deep hole processing equipment (T2120 deep hole drilling and boring machine) can not be matched; Because the outer diameter of the supporting tool on the original machine tool is 38, the total length of the parts must be 750 -- 1500, and the existing conditions can not realize the deep hole processing requirement of pipe diameter at all. Thus, the deep hole processing technology of titanium alloy pipe becomes the key technology to be solved urgently.
