Laser processing technology is an advanced manufacturing technology, and laser cutting is a part of the application field of laser processing. Laser cutting is currently an advanced cutting process in the world. Due to its advantages of precision manufacturing, flexible cutting, irregular machining, one-time forming, fast speed, and high efficiency, it has solved many problems that conventional methods cannot solve in industrial production.
Laser cutting technology mainly uses a high-power density laser beam to irradiate the cut material, obtaining a power density exceeding 104W/mm2 at the beam focus, which quickly heats the material to the vaporization temperature and evaporates to form holes. As the beam moves the material, the holes continuously form narrow slits (such as about 0.1mm), completing the cutting of the material. Laser cutting can be divided into three categories: laser vaporization cutting, laser melting cutting, laser oxygen cutting, and laser scribing and controlled fracture.
In addition to the supporting components, moving components, and corresponding motion control devices required for general machine tools, laser cutting equipment should also be equipped with a laser processing system, which is composed of three parts: laser, focusing system, and electrical system.
1. Good cutting quality, reducing labor costs
The laser cutting machine utilizes the characteristics of non-contact laser processing, which does not damage the workpiece, and the cut product has no extrusion deformation. The processed product has good quality, no burrs, and does not require manual polishing, eliminating unnecessary processing procedures and optimizing the labor intensity of workers.
2. Save mold investment and reduce production costs
Laser cutting machines can directly produce various hardware workpieces without molds, without mold consumption, without the need for repair and replacement of molds. They can save a large number of mold usage, save processing costs, and reduce production costs, especially suitable for the processing of large products.
3. High precision, effectively improving productivity
Laser cutting technology, as an alternative to “shearing punching”, has emerged with precise, flexible, and efficient characteristics. It can effectively process various complex parts. Simply create cutting graphics and import them into the control system to set dimensions for cutting, which helps directly shorten the product processing and manufacturing cycle and effectively improve labor productivity.
4. Fast cutting speed, optimized working environment
The laser cutting machine cuts quickly, with stable equipment, low noise, and no dust during operation. It does not produce harmful chemicals to the human body and environment, and is also a thoughtful protection for operators. It ensures the cleanliness and tidiness of the production site, reduces investment in the later stage, reduces pollution, and helps hardware enterprises promote the optimization of the working environment and comply with the trend of environmental protection.
5. Low maintenance costs and high cost-effectiveness in the later stage
The maintenance of mechanical products is very expensive, while laser cutting machines have stable performance, are sturdy and durable, can work continuously, and are not easily damaged. They have great advantages in terms of maintenance costs in the later stage.
