High-precision machine tools for engine machining
The key components of the aero engine are mainly the casing and the blades. There are three types of casing: split ring structure, integral ring shape, and profiled shell. The aero engine casing is a high-strength high-strength titanium alloy material. The front casing temperature is 200°C-300°C, while the rear casing is resistant to higher temperatures, which is difficult to process. The casing is also a large part. A 15,000 kg thrust engine has a diameter of 800 mm and a long processing time. Therefore, it is important to improve the machining efficiency.
Machine processing requires multi-functional, high-precision CNC machine tools, such as CNC vertical lathes, CNC precision boring machines and five-axis machining centers. It requires dual-station, on-line measurement and simulation functions. The magazine has a capacity of 60 knives and the CNC system has advanced Programming function, high-speed machining spindle speed 10000r/min or more, spindle power 15 kW ~ 30 kW. Roughing uses heavy cutting, so the machine must have sufficient strength. Finishing uses high-speed cutting, and many small holes in the casing are punched with an electric machine.
Blade machining is divided into two parts, namely the turbine blade and the impeller (ie the integral blade disc). The blade material is a high-temperature resistant titanium alloy material, which requires a five-axis linkage machining center, five-axis high-speed gantry milling, etc. to process the blade shape, and the milling processing amount is large. The broaching machine for the processing of the leaf root hoe and the slow-feeding to the powerful grinding machine require the slow-feeding grinding machine to have the function of changing the grinding wheel and the wheel dressing wheel device, and also need to use online measurement, program adjustment and automatic compensation function.
Electrolytic machining of the blade surface can greatly improve the processing efficiency, and it needs to be polished by numerically controlled six-axis belt polishing equipment, which requires the machine to have a blade surface inspection device. If electrolytic machining is used, it is necessary to prevent corrosion, electrolyte treatment, and insulation measures, which will increase environmental protection costs.
The blade has a lot of holes for cooling, and is punched with electric pulses, such as laser drilling (laser drilling has a hardened layer), but now the electroforming hole has no hole-pervious display, and the operation is difficult. The user unit hopes to solve this problem and enable the machine to display the punching process.
Most require a five-axis linkage machine
The structural features of typical parts of the aerospace industry are the extensive use of integral thin-walled structures with complex shapes. In order to increase the mobility of the aircraft, increase the payload and range, reduce the cost, carry out lightweight design and extensive use of new lightweight materials, and the material performance requirements are getting higher and higher. A large number of aluminum alloys, high-temperature alloys, titanium alloys, high-strength steels, composite materials, engineering ceramics, etc. are now used. The thin-walled parts and honeycomb parts with complicated structure have poor process rigidity.
The aviation industry needs a five-axis linkage machining center with A/B swing angle or A/C swing angle, high-speed machining center, large double-gantry vertical machining center, large-scale CNC gantry boring and milling machine, precision CNC lathe, large CNC precision vertical turning Center, turning and milling composite machining center, leaf disc efficient machining center, section arc tooth grinding machine, high speed rotor tip grinding machine, slow feeding strong grinding machine, broaching machine, electric processing machine tool, laser cladding machine tool, and moldless parts Point forming presses, directional single crystal melting furnaces, electro-hydraulic beam devices, and the like. The machine tool is required to have sufficient rigidity, simple operation, clear human-machine interface, spline interpolation (NURBS), process uniform control and online measurement simulation.
