Processing method of thin-walled custom titanium alloy parts

Our processing plant cooperates with a well-known university in China to develop scientific research projects. One of the parts is titanium alloy material. The titanium alloy material has four different chemical components, namely TC4, T3, T760 and T820, of which TC4 bar is in the market. Can be bought, the other three are special titanium alloy steel, can not be purchased in the market, is provided by the university. Each material is processed in several pieces, totaling more than 10 pieces. The technical requirements of the part: the coaxiality error of the outer surface and the inner surface is ≤0.04mm, and the surface roughness value is R.=1.6um.

Processing plant process analysis


(1) Because of the amount of processing and the influence of materials, it is impossible to provide blanks by hot forging and rough forming, and it is impossible to use the sheet spin forming process, which can only be realized by bar processing.


(2) Processing route analysis: The part belongs to a typical thin-walled part, the thickest part is 2.2mm, and the thinnest part is on the skirt side, only 1.37mm. The two planned routes are as follows: 1 first inner and outer outer method: firstly, the inner arc SR24.6mm is finished, then cut off, and the car is used to locate the mandrel, and the top is tight and then turned. 2 first and then the inner method: after the bar outer round rough car, Dongguan cnc processing plant uses the CNC lathe subroutine nesting, gradually approaching the outer arc SR25.5mm, then cut off, the car special positioning screw sleeve locks, The inner hole cutter is turned again. In the first method, there is a case where the rotating core is not processed, and the pattern requirement cannot be satisfied. The second method is firm and the processing quality is stable.


(3) According to the author's experience in processing titanium alloy, the titanium alloy should be cut from the two aspects of reducing cutting temperature and reducing adhesion. It has good red hardness, high flexural strength, good thermal conductivity and poor affinity with titanium alloy. Tool material.
