Laser precision machining what are involved in the field

As the growing demand for the high precision machining, precision machining technology is also associated with the fast development, the precision of laser cutting machine, also got more and more recognition in the market.



predominantly sheet precision laser cutting machine processing technology, high machining accuracy, high speed, incision smooth level off, the subsequent processing are generally not required; Cutting heat affected zone is small, plate deformation; High machining precision, good repeatability, does not damage the material surface. At present the application of precision machining industry is becoming more and more PCB board cutting, microelectronics circuit template precision cutting, glasses, jewelry industry.



laser precision machining has the following marked characteristics:



( 1) A wide range: laser precision machining object range is very wide, including almost all of the metal materials and nonmetal materials; Suitable for material of sintering, punching, marking, cutting, welding, surface modification and chemical vapor deposition, etc. And electrolytic machining only conductive material, photochemical processing is only applicable to easy corrosion materials, plasma processing is difficult to machining materials in some high melting point.



( 2) Precision: laser beam can be focused to a small size, and therefore particularly suitable for precision machining. Factors influencing the quality of laser precision machining, the machining accuracy is high, in the general case is superior to other traditional processing methods.



( 3) High speed and quick: from the point of processing cycle, edm tool electrode accuracy requirement is high, the loss is big, processing cycle is long; Electrolytic machining of mould cavity, large work volume on the cathode mold design, manufacturing cycle is very long; Photochemical processes complex; With laser precision machining operation is simple, cutting seam width, convenient regulation can be immediately according to the computer output pattern for the high speed engraving and cutting, processing speed, processing cycle shorter than other methods.



( 4) Safe and reliable: laser precision machining is non-contact, won't cause mechanical extrusion or mechanical stress to material; Relative to the electric spark machining, the plasma arc, its heat affected zone and deformation is small, so can work very small parts.



( 5) Low cost: not limited by processing quantity, for small batch processing services, laser processing are cheaper. For processing large products, bulk products mould manufacturing cost is very high, laser processing does not need any mould manufacturing, punching and shearing and laser processing completely avoid materials formed when the collapse edge, can greatly reduce the production cost of enterprises to improve the grade of the product.



( 6) Cutting seam small: laser cutting slot is in commonly 0. 1 - 0. 2mm.



( 7) Cutting surface smooth: laser cutting cutting surface, no burr.



( 8) Thermal deformation small, fine laser processing laser cutting, high speed, energy, concentration, quantity of heat is small, so to be cut material cause deformation of the material also is very small.



( 9) Save material: laser processing with computer programming, can put the different shapes of products to suit cut materials, maximize the utilization rate of materials, greatly reduces the enterprise the cost of materials.



( 10) Very suitable for the development of new products: once the drawing forming, laser processing can be done, immediately you can in the shortest possible time get the object of the new product.



overall, laser precision machining technology has many advantages than traditional processing methods, it has very broad application prospect.
