Application requirements upgrade of laser cutting machine

Release time:2021-01-22 source:Dongguan Xinke Laser Technology Co., Ltd

CNC laser cutting machine is widely used in all walks of life, such as automobile industry, shipbuilding industry, power generation equipment, aerospace, military equipment and so on. Because of its high efficiency and high precision, it can meet the increasingly progressive processing requirements of all walks of life. With the rapid development of science and technology, the processing requirements of the future mechanical industry will be higher. In order to make the CNC cutting performance meet the processing requirements of continuous progress, various industries put forward higher requirements for the CNC laser cutting machine. Laser cutting machine application requirements upgrade:

Automobile engine and body stamping parts production line has the characteristics of continuity, high efficiency and high reliability. The automobile industry requires to study the process characteristics of automobile parts, communicate with the automobile industry, and jointly develop a complete set of flexible production line with modularization and serialization. The flexible production line takes the processing of key parts such as engine block, cylinder head, crankshaft, connecting rod, camshaft and box as the object, adapts to the rapid combination of mixed production modules, reorganizes the production line, grasps the integrated technology of function evaluation, error tracing, quality control and management, and develops high-speed, precise and reliable CNC laser cutting machine with high-speed reclaiming and auxiliary functions If the equipment has deburring function, etc.

The hub processing parts of large ships are concentrated in the base, frame, cylinder block, cylinder head, piston rod, crosshead, connecting rod, crankshaft of high-power diesel engine, as well as the transmission shaft, rudder shaft and propeller of gearbox. The hub processing parts are made of special alloy steel, which are generally processed in small batches, and the processing yield is required to be 100%. Hub processing parts have the characteristics of heavy weight, complex shape, high precision and difficult processing. Heavy and Super Heavy CNC laser cutting machines with high power, high reliability and multi axis are needed for the processing of large ship hinge parts.

For example, the single weight of pressure vessel in nuclear power plant is 400-500 tons, and the single weight of rotor of large steam turbine and generator is more than 100 tons, which requires reliable operation for more than 30 years. Therefore, the CNC laser cutting machine for the manufacture of key parts of power generation equipment is characterized by large specification, high rigidity and high reliability.

The structural characteristics of typical parts in aviation industry are that a large number of thin-walled structures are adopted and the shape is complex. In order to increase the mobility of the aircraft, increase the payload and range, reduce the cost, carry out lightweight design and widely use new lightweight materials. Now a large number of aluminum alloy, superalloy, titanium alloy, high strength steel, composite materials, engineering ceramics, etc. The shape of thin-walled and honeycomb parts with complex structure is complex, and there are many holes, cavities, grooves, stiffeners and so on. According to the structural characteristics and processing requirements of the parts processed in aviation industry, the CNC laser cutting machine is required to have enough rigidity, simple operation, clear man-machine interface, spline interpolation and average process control, so as to reduce the influence on the processing accuracy of the corner, and has the function of online measurement simulation.
