Problems solved by technology

However, in the existing laser processing, there will be some incompletely evaporated molten materials at the beam irradiation place, which will accumulate on the processing surface to form a recast layer; when the molten material releases heat and solidifies to form a recast layer, its exothermic The process will produce uneven local heat distribution, which will easily cause uneven processing surface and a large number of fine cracks in the processing place, affecting the quality and life of the workpiece

Description

【Technical field】 [0001] The invention relates to a forming processing technology, in particular to a device for forming by using a laser. 【Background technique】 [0002] With the advancement of science and technology, in the manufacture of computers, communications, consumer electronics and automotive products and their molds, the requirements for the refinement and precision of various spare parts are getting higher and higher. [0003] The refinement and precision of spare parts are closely related to forming processing technologies such as cutting, cutting, and drilling. Traditional fine forming processing methods generally include milling, etching, electrical discharge machining, and laser processing. [0004] Milling is the use of forming tools, under the control of the computer, to cut the workpiece by means of rotating contact cutting. This processing method is greatly affected by the size of the material and the tool. When the workpiece is small in size and is a su...
