Application and characteristics of laser finishing

   Precision machining technology has the characteristics of high precision, fast speed, smooth incision, no need for subsequent processing, etc. : in the processing process, the cutting heat affected area is small, the plate deformation is small, the processing precision is high, repeatability is good, do not destroy the material surface.And the application is very wide, common PCB board cutting, microelectronic circuit template precision cutting, glasses industry, jewelry industry.

 

Unique advantages of laser finishing are as follows:

(1) Wide range:

   Object range of laser precision machining is very wide, including almost all metal materials and nonmetal materials.Suitable for material sintering, drilling, marking, cutting, welding, surface modification, chemical vapor deposition, etc.Electrochemical machining can only process conductive materials, photochemical machining is only suitable for corrosion-prone materials, plasma machining is difficult to process some high melting point materials.

 

(2) Rigorous and meticulous:

   Laser beams can be focused to very small sizes and are therefore particularly suitable for precision machining.Laser precision machining quality is generally superior to other traditional machining methods due to its fewer influencing factors and higher machining precision.

 

(3) High speed:

   From the point of machining cycle, the electrode of EDM tool has the characteristics of high precision, high loss and long machining cycle.Electrochemical machining cavity, surface cathode mold design workload is large, long production cycle;Photochemical processing is complex;Laser precision machining operation is simple, the width of the slit is very convenient to control, you can immediately according to the computer output mode of high speed engraving and cutting, the processing speed is fast, the processing cycle is shorter than other methods.

 

(4) Safe and reliable:

   Laser precision machining belongs to non-contact processing, which will not produce mechanical extrusion or mechanical stress on the material.Compared with edM and PLASMA arc machining, its heat affected area and deformation are very small, so it can process very small parts.

 


(5) Low cost:

   Not limited by the number of processing, for small batch processing services, laser processing is cheaper.Processing large products, large products mold manufacturing cost is very high, laser processing does not need any mold manufacturing and laser processing completely avoid the collapse edge caused by material punching, shearing, can greatly reduce the production cost of enterprises, improve product quality.

 

(6) Fine cutting:

Slit of laser cutting is generally 0.1-0.2mm.

 

(7) Smooth cutting surface:

Cutting surface of laser cutting has no burr.

 

(8) Small thermal deformation:

Laser cutting seam of laser processing is thin, fast and concentrated, so the heat transferred to the cut material is very small, the deformation of the material is very small.

 

(9) Preservation materials:

Laser processing adopts computer programming, which can integrate the material of different shapes into one, improve the material utilization rate to the maximum extent, and greatly reduce the material cost of enterprises.
