The production line of auto body stamping parts has the characteristics of continuous, high efficiency and high reliability. The auto industry requires to be able to study the process characteristics of auto parts, and to communicate with the auto industry to develop a complete set of flexible production line with modularization and serialization. The flexible production line takes the processing of automobile engine cylinder block, cylinder head, crankshaft, connecting rod, camshaft, box and other hub processing parts as the object, adapts to the rapid combination of mixed production modules, can reorganize the production line, grasps the integrated technology of function evaluation, error tracing, quality control and Governance, develops high-speed, precise and reliable CNC cutting machine, and has high-speed material taking and auxiliary equipment Such as deburring function.
The hub processing parts of large-scale 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 reduction gearbox, etc. the hub processing parts are made of special alloy steel, generally small batch processing, requiring the processing yield. The hub machining parts have the characteristics of large weight, complex shape, high precision and difficult machining. The machining of large-scale ship hub parts requires heavy and Super Heavy CNC cutting machines with high power, high reliability and multi axes.
For example, the weight of a single pressure vessel in a nuclear power plant is 400-500 tons, and the weight of a single rotor of a large steam turbine and generator is more than 100 tons, which requires reliable operation for more than 30 years. Therefore, the CNC cutting machine for the manufacturing of the key parts of the power generation equipment is characterized by large specification, high rigidity and high reliability.
The structural characteristics of the typical parts in the aviation industry are that the whole thin-walled structure is widely used and the shape is complex. In order to increase the maneuverability 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, high-temperature alloy, titanium alloy, high-strength steel, composite materials, engineering ceramics, etc. The shape of the 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 machined parts in the aviation industry, the CNC cutting machine is required to have enough rigidity, simple operation, clear human-machine interface, spline interpolation and process average control, so as to reduce the impact on the processing accuracy at the corner, and have online measurement and simulation function. leapion
