As technology constantly breakthroughs, laser power increasing, which makes the laser processing of development by leaps and bounds. Thick steel plate, can be processed, which means not only the efficiency value reached a very high level. Carved painting machine excitation light engraving effect brought about by the effect is to have an unprecedented chance, always use electric machining way of small complex parts, also has made many things become possible, especially when the request processing thousands of different shape, different sizes of complex shape small parts, the traditional processing technology will be facing the predicament of low efficiency and poor quality. These problems in the near future will be very good solve.
