requirements for machining accuracy of mechanical parts

automotive parts such as fuel injector, power steering gear, ABS brake, throttle valve, air conditioning compressor parts, rocker arm and so on have very high requirements for machining accuracy. The machine tool equipment must reach a very high machining level and have enough flexibility to cope with product changes

The achievements of the b/c axis

common rail fuel injection technology of the Mikron nrg-50 rotary modular machine tool have transformed the diesel engine from the impression of noise and pollution into an efficient modern power source. At the same time, it has stimulated the progress of the machine tool processing technology and the application and development of high-performance machine tools, and made it step to a new level in the special production technology

as diesel engines are favored by more and more drivers, their achievements and production processes are also applied to direct injection gasoline engines

increasingly stringent requirements

the fuel injector of diesel and gasoline engines is a key part with extremely high technical requirements, because it directly affects the fuel combustion performance and final emission of vehicles. With the increasingly stringent requirements of various environmental protection legislation, the related design, processing technology and equipment, manufacturing process, etc. must constantly break through the existing limits

there are also forces from the market. With the constant change of the consumer economy, consumers demand high performance, low price, low fuel consumption and longer reliable working time, which means higher performance, higher pump pressure and more precise fuel flow for the engine fuel injector. To reach a higher level in these aspects, it is necessary to improve the machining accuracy of parts and reduce the dimensional error of parts as much as possible. The size is more precise and the geometric tolerance is smaller, which also meets the requirements of the continuously developing vehicle management system software and control electronic components

to meet such requirements, the materials used for the parts may need to be changed, which may mean that the parts are more difficult to process, the surface requirements are more precise, and the number of parts to be assembled will be reduced, which also makes the parts more complex. All these require that the processing equipment must have higher production consistency, and the allowable error or deviation is very small or even no error, It is better that the whole processing process should also be integrated into a processing cycle. Parts can be processed in multiple processes in a shorter time through one clamping and positioning. Obviously, this further increases the complexity factor of processing and manufacturing

mature technology
