Laser cutting equipment has become very popular in our life, but the laser technology used in various industries is very different. At present, the mature laser processing technologies include: laser rapid prototyping technology, laser welding technology, laser drilling technology, laser cutting technology, laser marking technology, laser weight removal and balancing technology, laser etching technology, laser trimming technology, laser storage technology, laser scribing technology, laser cleaning technology, laser heat treatment and surface treatment technology. Now we will introduce the practical application of several typical laser cutting equipment.

Application of metal laser cutting machine in machinery manufacturing industry

Laser cutting technology can be widely used in the processing of metal and non-metallic materials, which can greatly reduce processing time, reduce processing costs, and improve the quality of the workpiece. Pulse laser is applicable to metal materials, and continuous laser is applicable to non-metallic materials, the latter is an important application field of laser cutting technology.

1. Application of metal laser cutting machine in automobile manufacturing

In the automotive industry, laser processing usually focuses on cutting. High power carbon dioxide laser is generally used for laser beam cutting. In order to improve the cutting speed and cutting quality of metal cutting machine, nozzles are generally installed at the beam outlet of carbon dioxide laser cutting machine to inject gas during cutting. Since the metal surface has a wavelength of 10.6 Ч M has high light wave reflectivity, and oxygen or compressed air is often injected into the metal workpiece to improve the cutting efficiency; When cutting flammable materials, inert gases such as nitrogen are injected to prevent combustion.

2. Application of metal laser cutting machine in shipbuilding industry

Metal laser cutting machine usually uses auxiliary oxygen to speed up the cutting speed and obtain high-quality cutting effect, but this is generally only applicable to cutting carbon steel plates with thickness less than 20mm. In addition, Render Shipbuilding Co., Ltd. was established in Alabama more than one year ago. A new cutting process consisting of laser and (pressurized) oxygen is used to cut 50mm thick steel plates, while the power of CO2 laser system used for cutting is less than 2kW. This cutting method has the potential to cut 100mm thick steel plates.
