Eighth Research Institute of China Aerospace Science and Technology Corporation
The Company began technical cooperation with the Eighth Research Institute of China Aerospace Science and Technology Corporation in November 2019. The company's special powder high-speed steel drill bits for titanium alloy and special taps for Aviation standard (MJ) titanium alloy have been tested in the workshop. At present, more than 5400 ordinary titanium alloy parts and more than 3800 Aviation standard titanium alloy parts have been processed.
Among them, the D3.2 powder high-speed steel drill bit used for titanium alloy drilling has a wear resistance of about 8 times that of the original tool. The processed hole has a good consistency, the size fully meets the requirements, and the quality of the drill surface is excellent. The unique design of the drill point centering groove makes the drill more stable during deep hole processing, which avoids the problem of drilling position deviation. The side edge of the drill is designed with a positive rake angle of 2.5 degrees, which plays the role of cutting while drilling, making the hole wall processing quality more superior. The unique chip groove design allows the drill to discharge chips very smoothly when machining titanium alloy, which is a good solution to the problem of titanium alloy winding chips. Under the comprehensive evaluation of the workshop, compared with other brands of drill bits, the company's drill bits can improve the drilling efficiency, reduce the scrap rate of workpieces, and perform well in the field of titanium alloys.
Among them, the special tap product of Aviation standard (MJ) titanium alloy for high-strength thread processing of titanium alloy has wear resistance 5 times that of the original tool. After processing, the thread accuracy is very good, and the thread surface quality is excellent. The unique small spiral angle groove design makes the tap very smooth chip removal during titanium alloy processing. In the comprehensive evaluation, the company's tap products compared to other domestic brands, can improve the efficiency of thread processing, improve the service life of the tool, reduce the scrap rate of the workpiece.
