Laser marking is a very fine spot to play a variety of symbols, text, graphics, etc., spot size can microns. Micro plus or security work has a deeper meaning. Like fine laser focus after the razor, the surface of the material can be removed by point by point. The greatest benefit is that the process is non-contact machining marks in nature, does not adversely scratch and friction, it will not cause squeezing or crushing and so on. It will not damage the article to be machined. Because the laser beam spot becomes finer zoom again, a small area to produce thermal effects, processing precision, so you can complete some routine can not be completed, the process can not be achieved. Laser processing can aid modern CAD / CAM software, to achieve any form of sheet metal cutting, laser processing, not only fast processing speed, high efficiency, low cost, and avoid mold replacement, shorten the production cycle time to prepare. Easy to implement continuous process, the laser beam transposition short time, improve production efficiency. A variety of workpieces can be alternately installed. When machining a workpiece, can remove the finished part, and mounting a workpiece to be machined, to achieve parallel processing, to reduce the mounting time, increases the laser processing time. Laser cutting its high-speed and high-precision, high-quality, energy-saving and environmental protection features, has become the technology development direction of modern metalworking. In the laser processing applications, laser cutting accounted for 32% market share. Laser cutting compared with other cutting methods, the biggest difference is that it has a high-speed, high precision and high adaptability characteristics. It also has a slotted small, small heat-affected zone, good quality cutting surface, no noise when cutting, good kerf edge vertical, smooth cutting edge, the cutting process is easy to achieve automatic control and so on. Laser cutting sheet metal, do not die, some alternative methods require the use of complex punching large molds, can greatly shorten the production cycle and cost. Sheet metal processing is a key technology of sheet metal technicians need to know, is an important process shaping sheet metal products. It includes the traditional cutting methods and processes cutting, punching, bending pressure forming, etc., but also includes a variety of cold stamping die structure and process parameters, various equipment works and method of operation, including new stamping techniques and new technology . Pieces of sheet metal processing of agricultural products generally use 4-6mm steel plate, sheet metal variety, and updated quickly, the traditional agricultural products commonly used pieces of sheet metal processing punch way, mold loss, usually a large agricultural producers for die storage warehouse near 300 square meters, the processing can be seen that if the parts are still stuck in the traditional way, will severely restrict the rapid technological upgrading and product development, and flexible laser processing advantages manifested.
