High-quality titanium processing
Since the quality and accuracy of the mold is critical for titanium machining, we have our own in-house tooling facilities. EDM technology is used to create high-quality tools that can cut titanium without reducing the quality of the workpiece or cutting tool.
The ultimate secret to the success of titanium machined parts is the keen eyes and experienced hands of our artisans who oversee the titanium machining process. They use decades of experience to ensure that cutting speeds, feed rates, cutting fluids and tool conditions are perfectly maintained for precision titanium CNC machining.
Titanium processing characteristics
Compared to other materials, machining titanium has several advantages. Titanium machined parts are known for their high strength and weight; it is also malleable, resistant to salt and water, and has a high melting point, making it an ideal choice for many industries and applications.
Tooling technology for titanium alloy parts
The clamping principle of titanium alloy parts is:
(1) The clamping force in the roughing stage should be large to prevent the parts from loosening during the large cutting force processing; the clamping force should be small in the finishing stage to prevent the clamping deformation.
(2) The clamping force acts on a place with good rigidity, and as many points as possible.
(3) For the thin-walled structural parts with poor rigidity, appropriate auxiliary devices should be added to increase the rigidity of the entire processing technology system.
A large number of specialized fixtures with a high degree of automation are used abroad. If hydraulic adjustment tools are used, the pressure plate is automatically released when the cutting tool approaches the pressing point in the outer contour of the processed part. After the tool is cut, the pressure plate immediately returns to the original position to press the part. There are also some companies that use the same materials as the parts being processed to make fixtures and pressure plates, which are integrated into the part during clamping. There is no need to consider avoiding the fixture pressure plate during the cutting process, and the processing efficiency is significantly improved.
The domestic lack of in-depth research and development of tooling fixtures in the numerical control machining of titanium alloy aerospace structural parts, and more simple mechanical clamping methods are used. The simple mechanical clamping method is affected by human factors, and the clamping force is not easy to control. There are also some flat-type single-sided structures and small-thickness structural parts that are clamped using a vacuum suction method, while the vacuum suction method has a poor adsorption effect on structural parts with large thickness and double-sided structures.
Titanium processing tool technology
With the development of high-speed cutting technology, high-speed cutting tool materials and tool manufacturing technology have undergone tremendous changes, and new materials, new coatings and new technologies have continuously emerged. However, the current tool technology is still a technical bottleneck that limits the improvement of the processing efficiency of difficult-to-machine materials such as titanium alloys. Titanium alloy has low elastic modulus, large elastic deformation, high cutting temperature, low thermal conductivity, and high chemical activity at high temperature, which makes the phenomenon of cutting sticking serious. It is easy to aggravate tool wear and even damage, resulting in poor machining performance of titanium alloy. Therefore, titanium alloy machining tool technology has become one of the key technologies that restrict the efficient machining of titanium alloys.
From the perspective of improving the metal removal rate, the current high-efficiency roughing tools for titanium alloy aviation structural parts include corn milling cutters, plunge milling cutters, high-feed milling cutters, and combination cutters (see Figure 3). Among them, the use of corn, plunge cutters and combined tools has certain requirements on the power and torque of the machine tool, while the large feed milling cutter has no special requirements on the power and torque of the machine tool and rigidity. Existing machining applications have shown that with large feed milling cutters, cutting efficiency can be effectively improved by more than 50%.
Starting from controlling the machining accuracy of the parts, the high-efficiency finishing tools for titanium alloy aerospace structural parts are mainly integral end mills, as shown in Figure 4. The use of dense-tooth tools (5 to 10 teeth) can significantly improve the surface roughness of the machining, and the use of unequal pitch end mills can effectively improve the ultimate depth of cut.
With the emergence of new cutting tool materials and the continuous development of new cutting tools, a lot of research work has been done on cutting tools for titanium alloys at home and abroad. For example, T. Kitagawa et al. Have studied the cutting mechanism of titanium alloys in the machining of cemented carbide tools, and it has been shown that the grain size of carbide tools and the content of Co element directly affect their performance when cutting titanium alloys, and pointed out that YG type hard alloy Alloy tools are more suitable for machining titanium alloys. J. Vigneau has studied the cutting performance of coated tools for cutting titanium alloys. Traditional coatings are mostly TiC and TiCN coatings. During the cutting process, the Ti element tends to affinity with the workpiece and accelerate the tool wear speed. CBN is a good tool for high-speed cutting of titanium alloys due to its high hardness, good heat resistance and high stability. This kind of tool is relatively expensive, and relevant domestic institutions have not conducted in-depth research. In terms of tool structure design, GD Vasilyuk increased cutting damping by increasing the arc radius of the tool tip, thereby eliminating chatter; CRLIU suppressed chatter by controlling the rake angle, rake angle, and inclination of the tool online during the cutting process; German scholars V. Sellmeiert conducts experimental and theoretical research on the stability of unequal pitch end mills.
