Matters needing attention in titanium tube processing parts

1. Titanium alloy cutting is a strong cutting, so the machine tool spindle has a large driving force and a high-power strong cutting function. In the aviation industry, the processing of titanium alloy components is mainly mold milling. In order to facilitate chip removal, the cooling and lubrication device must be managed to facilitate chip removal, and the cooling and lubrication device must be managed so that a large amount of high-pressure cooling lubricant is directly sprayed on the cutting edge of the tool. In this way, on the one hand, the tool can be cooled, and on the other hand, the chips can be moved out of the machining area in a better and timely manner, so as to avoid removing the chips through multiple cuts, reducing the tool life and scratching the machined surface. In order to make the machine tool play an excellent role, Heller has the function of overriding cutting, specially designed the machine tool structure and coordinate axis structure, and installed a solid cutting swing unit on the main shaft, which has excellent rigidity, so that the machine tool can produce the same effect at any angle. The cutting force, vertical, horizontal and spatial.

2. Titanium alloys are characterized by high strength and poor thermal conductivity. In order to achieve the same cutting efficiency as machining aluminum, the cutting parameters should be increased as much as possible, that is, increasing the amount of gold input and the depth of cut, which will lead to an increase in cutting force, which will lead to an increase in cutting force. Static misalignment between workpiece and tool, which results in poor shape accuracy of the part or unstable machining process, and also accelerates tool wear. Therefore, the machine tools used for the machining of titanium tubes must have high power and good static and dynamic characteristics (high static and dynamic stiffness). Corresponding high-pressure cooling and lubricating equipment is also required for low-speed, high-torque applications. In order to improve the rigidity of the machine tool, some machine tool manufacturers have adopted a box-shaped structure or a welded steel structure with a closed frame. The feed shaft is driven by a high-power feed motor, and the high-rigidity, gap-free guide rail can be clamped to the processing position for the system to further improve the rigidity of the machine; in addition, during the processing, the entire system must be improved. Rigidity, including spindle cutter linkage position and handle holder.

3. In addition to the static stiffness, the dynamic characteristics of the machine tool also play a decisive role in effective titanium alloy machining. Controlling the stability of the machining process is a huge challenge. If the stiffness and damping characteristics of the machine tool are poor, self-excited vibration may occur due to the dynamic influence such as close to the natural frequency due to the large cutting force , low rotational speed and excitation frequency of the machine tool during the cutting process , and cause the machining process. vibration. In addition to affecting the surface quality of the workpiece (with vibrating particles), this chatter can cause damage to the structure of the machine tool, tool Zhuzhou and overloaded tools. Tool wear increases or even breaks. Machining process stability mainly depends on the selected spindle speed, depth of cut and other parameters. The user understands the performance of the machine tool and may reach the limit of the depth of cut, and can also take the initiative to take vibration-damping pads and set parameters in the machine tool control device in advance to avoid the limit of the depth of cut. Small-scale rotational vibration measures further improve the shock resistance of the machine tool.
