CNC laser cutting machines are widely used in all walks of life because their high efficiency and high precision can meet the increasingly advanced processing requirements of all walks of life. With the rapid development of science and technology, the machining requirements of the machinery industry will be higher in the future. In order to meet the continuously improving processing requirements of CNC cutting performance, various industries have put forward the following requirements for CNC laser cutting machines:   Automotive engine and body stamping production line With the characteristics of continuous, high efficiency and high reliability, the automotive industry requires the ability to specialize in the process characteristics of automotive parts, communicate with the automotive industry and jointly develop a modular and serialized complete set of flexible production lines. The flexible production line focuses on the processing of hub machining parts such as automobile engine cylinder blocks, cylinder heads, crankshafts, connecting rods, camshafts, boxes, etc. The rapid combination of modules suitable for mixed production can reorganize the production line, and grasp the performance evaluation, error traceability, Quality control and management integration technology, development of high-speed, precise, reliable CNC cutting machine, at the same time with high-speed reclaiming, auxiliary equipment such as deburring function. The pivot processing parts of large ships are concentrated in the base, frame, cylinder block, cylinder head, piston rod, crosshead, connecting rod, crankshaft, and gearbox transmission shaft, rudder shaft and propeller of high-power diesel engine. Hub processing The material of the parts is special alloy steel, which is generally processed in small batches, and the finished product rate is required to be 100%. Hub processing parts have the characteristics of heavy weight, complex appearance, high precision, and difficulty in processing. The processing of large-scale ship pivot parts requires heavy-duty and super-heavy CNC cutting machines with high power, high reliability and multi-axis. Power generation equipment hub processing parts are heavy, special appearance, high precision, difficult to process, and expensive. For example, the pressure vessel of nuclear power station weighs 400~500 tons, and the rotor of large steam turbines and generators weighs more than 100 tons, which requires reliability. Work for more than 30 years. Therefore, the numerical control cutting machine required for the manufacture of power generation equipment hub parts is characterized by large specifications, high rigidity, and high reliability.  The structural characteristics of typical parts in the aviation industry are the large number of integral thin-walled structures with complex shapes. In order to increase the maneuverability of aircraft, increase payload and range, reduce costs, carry out lightweight design and widely use new lightweight materials. Nowadays, aluminum alloys, high-temperature alloys, titanium alloys, high-strength steels, composite materials, engineering ceramics, etc. are widely used. Thin-walled parts and honeycomb parts with complex structures have complex shapes, with many holes, cavities, grooves, and reinforcing ribs, and poor process rigidity. According to the structural characteristics and processing requirements of the machined parts in the aviation industry, the CNC cutting machine is required to have sufficient rigidity, simple operation, clear man-machine interface, spline interpolation, and process average control to reduce the impact on the processing accuracy of the corners.
