The laser cutting machine generally uses direct processing of raw materials. Because the laser cutting speed is fast and the thermal deformation of parts is small, the accuracy requirements of laser cutting parts mainly depend on the mechanical accuracy and control accuracy of the laser cutting machine workbench.
For laser cutting, the evaluation of production and processing quality mainly includes the following principles:
1、 Laser cutting is smooth, without stripe and brittle fracture;
2、 The width of the incision is narrow, which is related to the diameter of the laser spot;
3、 The perpendicularity of the incision is good, and the range of heat damage is small;
4、 The raw materials do not burn naturally, the melting layer does not produce, and the slag is not large;
5、 In the process of laser cutting, the surface roughness of the tool is an important index to measure the machining performance of the tool.
In addition to the above principles, the state of the melting layer and the final forming state in the production process directly affect the evaluation index of the product processing quality.
The surface roughness of the laser is mainly shown in the following three aspects:
Inherent parameters of laser cutting system, such as spot mode, focal length, etc;
In the laser cutting process, adjustable process parameters, such as power, laser cutting speed, auxiliary gas type and pressure, etc;
At present, there are two main types of metal sheet metal cutting laser cutting machines in the sheet metal processing industry. One is the CO2 laser cutting machine that was transformed from an industrial laser into a product about 20 years ago, and the other is the optical fiber laser cutting machine that was formally transformed from an industrial laser into a product about 5 years ago. According to the number of laser cutting machines sold in China's sheet metal equipment market in recent years, CO2 laser cutting machines account for 40% and fiber laser cutting machines account for 60%. Although in 2007, almost 100% of the laser cutting machines sold in the market were CO2 laser cutting machines, we know that in recent years, the optical fiber laser cutting machines have a strong momentum, are constantly recognized by the market, and the number of sales is gradually expanding.
Physical parameters of raw materials for production and processing, such as laser absorption capacity, melting point, viscosity coefficient of molten metal oxide and surface tension. In addition, the thin wall thickness of the workpiece also seriously affects the technological performance of laser cutting. Relatively speaking, the thinner the metal workpiece, the higher the surface roughness of laser cutting.
In order to obtain better processing performance, the laser power, laser cutting rate and other processing parameters must be sublimated for many times. Due to the low melting point of metal materials, high thermal conductivity, low melt viscosity and low surface tension of metal oxides, laser cutting is easy to obtain high processability.

The price of 1500w optical fiber laser cutting machine is generally in the range of 200000 to 300000 yuan. Different manufacturers have different configurations, and the price will be different. If conditions permit, it is recommended to visit the manufacturer of optical fiber laser cutting machine on the spot. How to adjust the iron plate of the optical fiber cutting machine? Generally, different brands of optical fiber cutting machines have different operation and adjustment methods. You can consult the manufacturer of the optical fiber cutting machine or refer to the manual.
