According to data research of relevant industrial processing technologies, laser cutting is one of the most important cutting technology processes in the laser processing industry, and the proportion thereof can reach 70%, which shows that its application is extensive and important. Laser cutting technology is an important part of laser processing technology, and it is also one of the most recognized cutting-edge cutting processes in the world. With the rapid development of sheet metal processing technology, domestic processing technology is also on the move, and the gap between foreign countries is getting smaller and smaller. Many well-known foreign-funded enterprises have repeatedly transferred their manufacturing bases to China. At the same time, they have also given sheet metal processing belts. Many reactionary ideas came.
The practical advantages of laser cutting technology in application 3.1 The dual reduction in labor intensity and processing cost First, prior to the 1980s, the basic supporting parts such as racks and boxes used in our products were all cast iron parts. . Its advantages are structural stability and small deformation. The disadvantages are long mold manufacturing cycle, high mold cost, unsuitable for single-piece and small-batch production, large environmental pollution, and high labor intensity of workers. Since the 1980s, with the change of design concept, the pattern of producing a product for several decades has been broken, and the racks and boxes of welded steel plate structures have appeared in the products of winders and needle combs. At that time, the company did not have a laser cutting machine. In the face of racks and cabinets made of 6mm and 8mm thick steel plates, our processing methods were: cutting out the shape with a shear and cutting the surface of the plate with gas cutting. Then use a boring machine or a machining center to finish the inner surface of the board into a hole, and the holes with the concentricity are required. After the welding, the boring machine or the machining center is used for processing. The processing cycle is very long and the efficiency is low. With the laser cutting machine, shears, gas cutting and even boring machines or machining centers are eliminated. Most of the plates can be formed on the laser cutting machine and welded directly. Only few concentric holes are required. Requires that the hole be finished after the box is welded. This reduces equipment types, reduces processes, shortens construction time, and increases efficiency. It is possible to replace racks and boxes of cast-iron structures with racks and cabinets of plate-welded structures. The "welding" and "casting" of the spinning machine parts are realized. The resulting benefits are: reduced labor intensity of workers, improved the company's working environment, and reduced environmental pollution. In the trial production of new products: The research and development progress has been greatly accelerated, saving investment in molds and reducing costs.
3.2 Shortening of new product manufacturing cycle Before our company did not have a laser cutting machine, the thin plate processing below 3mm thickness can only be cut out with a shear, and all the structures in the plate surface must be completed on the stamping bed through the die. Even a non-standard washer part must be out of the mold, otherwise it cannot be processed. After the laser cutting machine is used, the machining of medium and small batches of parts is completely free of molds, and only a large number of parts need to be considered in the punching process. In particular, trial production of new products, with small quantities, uncertain structures, and changes at any time, can't produce molds at all. The laser cutting machine greatly shortens the manufacturing cycle of new products and reduces the investment in molds.
3.3 Significantly improve the processing efficiency The laser cutting machine has greatly improved the processing efficiency of the steel plate with a thickness of 4mm or more. Due to the restriction of the tonnage of the punch press, the steel plate with the thickness of 4mm or more cannot be punched and processed by the punching machine. It can only be rough cut by gas cutting, and then it can be finished by machining equipment. The result is: waste of material, increase of processes, and production cycle Long, low productivity, and increased costs. After the laser cutting machine is used, the steel plate with a thickness of 4 mm or more can be directly cut and lived as long as it is not a particularly accurate size. The gas cutting efficiency is higher, the accuracy is better, and the deformation is also small, eliminating the need for machining processes.
In summary, the advantages of the laser cutting machine make it widely used in many fields. Looking into the future, laser cutting machines will inevitably gain better prospects for development.
Machining Stainless steel is the use of CNC machining out, including drilling, boring, cutting, turning, screw, etc.. Machining stainless steel commonly used materials: sus303304316.stainless steel has a very high hardness after machining, easy deformation, so in the process of rough machining to eliminate stress, and then finished. Surface treatment is generally passivation, we have specialized laboratories to test products, and ensure that each size to meet the requirements of the drawings, including the machining stainless steel application in various industries: automobile, ship, crane, medical equipment, industrial automation equipment.
Of course,we also accept the custom machining,welcome to contact us.
