With the increasing demand for high-precision machining, related precision machining technology has also developed rapidly, among which CNC laser technology has also gained more and more recognition in the market. The thin plate-based precision cutting and processing technology adopts high-precision CNC fiber laser cutting machine. Compared with the original CNC plasma cutting machine, it has high processing precision, fast speed, smooth incision, and generally does not require subsequent processing; cutting heat affects The area is small, the deformation of the plate is small, and the surface of the material is not damaged. At present, there are more and more application industries of precision machining, such as PCB board cutting, microelectronic circuit template precision cutting, glasses industry, and jewelry industry.

Precision CNC laser cutting has the following salient features:

(1) Wide range: CNC laser cutting machine precision machining has a wide range of objects, including almost all metal materials and non-metal materials; suitable for material sintering, drilling, marking, cutting, welding, surface modification and chemical Vapor deposition, etc. Electrochemical processing can only process conductive materials, photochemical processing is only suitable for corrosive materials, and plasma processing is difficult to process some materials with high melting points.

(2) Precise and meticulous: The laser beam can be focused to a small size, so it is especially suitable for precision machining. Laser precision machining has few factors affecting the quality and high machining accuracy, which is generally better than other traditional machining methods.

(3) High speed and fast: From the perspective of the processing cycle, the tool electrode of EDM has high precision requirements, large loss, and long processing cycle; the design of the cavity and the cathode mold of the surface of electrolytic machining is heavy, and the manufacturing cycle is also It is very long; the photochemical processing process is complicated; and the CNC fiber laser cutting machine has simple laser precision processing operations, and the slit width is easy to adjust. It can immediately perform high-speed engraving and cutting according to the pattern output by the computer. The processing speed is fast, and the processing cycle is shorter than other methods. short.

(4) Safe and reliable: Laser precision machining is a non-contact machining and will not cause mechanical extrusion or mechanical stress to the material; compared with EDM and plasma arc machining, its heat-affected zone and deformation are very small, so it can be processed very small components.

(5) Low cost: not limited by the number of processing, laser processing is cheaper for small batch processing services. For the processing of large-scale products, the mold manufacturing cost of large-scale products is very high, and laser processing does not require any mold manufacturing, and laser processing completely avoids the slump formed when the material is punched and sheared, which can greatly reduce the production cost of enterprises and improve products. 's grade.

(6) Small cutting seam: The cutting seam of CNC fiber laser cutting machine is generally 0.1-0.2mm.

(7) Smooth cutting surface: There is no burr on the cutting surface cut by the CNC fiber laser cutting machine.

(8) Small thermal deformation: The laser processing of laser processing has thin slits, high speed and concentrated energy, so the heat transmitted to the material to be cut is small, and the deformation of the material is also very small.

(9) Material saving: Laser processing adopts computer programming, which can cut different shapes of products, maximize the utilization rate of materials, and greatly reduce the material cost of enterprises.

(10) It is very suitable for the development of new products: once the product drawings are formed, laser processing can be carried out immediately, and you can get the physical objects of new products in the shortest time.

In general, laser precision processing technology has many advantages over traditional processing methods, just as CNC fiber laser cutting machines have higher processing precision than CNC plasma cutting machines, and their application prospects are very broad.
