Several aspects to pay attention to in metal laser cutting

Laser cutting is the use of high energy density laser beam cutting materials of a new processing technology, the laser produced in the high energy density laser through the refraction is focused into a small beam of light spot, irradiation on the material can instantly melt the material to form a slit, so as to achieve the purpose of cutting.Laser cutting does not touch the object, the stress change and thermal reaction zone generated by the cutting process are small, and with the help of the control system, fast and high-precision cutting can be achieved.

Metal cutting is one of the most common laser processing applications, due to different metal materials, as well as different metal thickness between the property changes, so in the metal laser cutting we need to pay attention to the following aspects:
1. Laser parameters
Laser parameters include laser power, pulse frequency, processing speed, etc. Laser parameters are the most basic and most important reference data for laser cutting, we need to set the laser parameters of the machine according to the actual situation. For example, cutting aluminum alloy and carbon steel of the same thickness, because aluminum alloy light reflectivity is high, so cutting aluminum alloy needs to increase power.
2. Laser configuration
Cutting metal requires the use of fiber laser, and fiber laser light and continuous laser and pulse laser options, which continuous laser is continuous emission of laser, and pulsed laser is according to the pulse frequency of the segmented emission of laser. Different thickness and material and metal materials, the type of laser used will be different, we need to use the right processing method, in order to make the cut out of the finished product to keep beautiful.
3.Auxiliary gas
Auxiliary gas can help the laser to melt the material faster, according to the different properties of the metal, with different auxiliary gas can get better cutting effect. For example,nitrogen and oxygen can be used to cut aluminum alloys, and the injection of gas helps to clear the melting area, improve the cutting speed, and reduce oxidation reactions and heat-affected zones.
4.Control system
The control system is the key to the operation of the equipment, a good control system, can ensure the stable and accurate long-term operation of the equipment, at the same time, some parts that need special treatment, also need to cooperate with the corresponding control system to process. For example, cutting curved metal requires a control system with a adjustable height function.
In addition to the functional differences, the above aspects also involve the issue of price, although the expensive is not necessarily good, but the good will generally be more expensive. So in the selection of various configurations, we should according to their own needs, for the processing task for comprehensive consideration, choose their own good.
