What are the applications of laser precision machining?


With the increase of the demand for high precision machining, the related precision machining technology also develops rapidly, among which the precision laser cutting machine has been more and more recognized in the market.

The precision laser cutting machine processing technology based on thin plate has the advantages of high precision, high speed, smooth incision and no subsequent processing; The cutting heat affected zone is small and the deformation of sheet is small; High machining accuracy, good repeatability, no damage to the material surface. At present, there are more and more application industries of precision machining, such as PCB cutting, microelectronic circuit template precision cutting, glasses industry, jewelry industry.

Laser precision machining has the following remarkable characteristics.

Wide range: laser precision machining has a wide range of objects, including almost all metal materials and non-metal materials; It is suitable for sintering, drilling, marking, cutting, welding, surface modification and chemical vapor deposition. Electrochemical machining can only process conductive materials, photochemical machining is only suitable for corrosive materials, plasma machining is difficult to process some high melting point materials.

Precision: the laser beam can be focused to a very small size, so it is especially suitable for precision machining. In general, laser precision machining is superior to other traditional machining methods due to its less influence factors and high machining accuracy.

High speed and fast: from the perspective of machining cycle, EDM tool electrode requires high precision, large loss and long machining cycle; The design of cathode die for machining cavity and surface is heavy and the manufacturing cycle is long; The process of photochemical processing is complex; The laser precision machining is easy to operate, and the slit width is easy to control. It can immediately carry out high-speed carving and cutting according to the computer output pattern. The processing speed is fast, and the processing cycle is shorter than other methods.

Safe and reliable: laser precision machining belongs to non-contact processing, which will not cause mechanical extrusion or mechanical stress to materials; Compared with EDM and plasma arc machining, its heat affected zone and deformation are very small, so it can process very small parts.

Low cost: not limited by the number of processing, for small batch processing services, laser processing is cheaper. For the processing of large products, the mold manufacturing cost of large products is very high, laser processing does not need any mold manufacturing, and laser processing completely avoids the collapse edge formed during material punching and shearing, which can greatly reduce the production cost of enterprises and improve the product grade.

Small cutting seam: the cutting seam of laser cutting is generally 0.1-0.2mm.

Smooth cutting surface: the cutting surface of laser cutting is free of burr.

Small thermal deformation: laser cutting is fine, fast and energy concentrated, so the heat transmitted to the cut material is small, resulting in very small deformation of materials.

Material saving: laser processing adopts computer programming, which can make different shape products to arbitrage materials, maximize the utilization of materials, and greatly reduce the material cost of enterprises.

It is very suitable for the development of new products: once the product drawing is formed, laser processing can be carried out immediately, and you can get the new product in the shortest time.

In general,precision laser machining technology has many advantages over traditional processing methods, and its application prospect is very broad.
