The cutting process of titanium alloy is strong cutting, so the spindle of the machine tool has a large driving force and a strong cutting function. In the aerospace industry, the machining of titanium alloy parts is mainly in the milling of cavities. To facilitate chip removal, cooling and lubrication units should be managed. To facilitate chip removal, cooling and lubrication units should be managed so that large quantities of high-pressure cooling lubricant can be sprayed directly. Knife. In this way, on the one hand, the tool can be cooled, and on the other hand, the chips can be flushed out of the machining area in time to prevent the chips from being cut multiple times, thus reducing the tool life. and scratch the machined surface. In order to make the machine tool have high-power cutting function, titanium machining parts manufacturers have designed the product structure and coordinate axis structure in a targeted manner, and are equipped with a powerful cutting and swinging unit, which has excellent rigidity to install the tool spindle, so the machine tool is in a vertical, horizontal and spatial state. The same cutting force can be generated at any angle.
Titanium alloys are characterized by high strength and poor thermal conductivity. In order to achieve cutting efficiency like machining aluminum, it is necessary to increase the cutting parameters as much as possible, i.e. increase the amount of gold and the depth of cutting, resulting in an increase in cutting forces, which can lead to static deviations between workpieces. and tools, which can cause damage to the parts. Reduced shape accuracy or unstable machining processes also accelerate tool wear. Therefore, machine tools for the machining of titanium alloys must have high power and have static and dynamic characteristics (high static and dynamic stiffness); It also needs to be equipped with corresponding high-pressure cooling lubrication equipment for low-speed, high-torque machining. Clean the chips in a timely manner to reduce tool wear and reduce the heat generated during machining. In order to improve the rigidity of machine tools, some machine tool manufacturers use welded steel structures in box structures or closed frames. The high-power feed motor driver of the feed axis and the high-stiffness backlash-free guide system can be fixed in the machining position to further increase the rigidity of the machine. In addition, the entire system, including the spindle tool linkage section and the tool holder, had to be improved. Stiffness during machining.
