Equipment selection
Laser cutting equipment mainly includes laser, cutting head, CNC system, workbench and other parts. When selecting laser cutting equipment, it is necessary to select the appropriate laser power, cutting head type and CNC system according to the requirements of processing materials, thickness, precision and other requirements.
Material preparation
Before laser cutting, the material needs to be properly prepared, including cleaning, deburring, flattening, etc., to ensure the smooth progress of the cutting process.
Programming
Laser cutting usually uses CNC programming, and the cutting trajectory and parameters are generated by computer software and then transmitted to the CNC system. Factors such as cutting speed, power, and focal position need to be considered during the programming process to obtain the best cutting effect.
Set parameters
Before starting cutting, it is necessary to set the relevant parameters of laser cutting according to the characteristics of the material and processing requirements, including laser power, cutting speed, focal position, auxiliary gas, etc.
Operating equipment
When operating laser cutting equipment, it is necessary to follow the operating procedures of the equipment to ensure the safe and stable operation of the equipment. During the operation, pay attention to observe the cutting effect and adjust the parameters in time to obtain satisfactory cutting quality.
After laser cutting is completed, the cut surface needs to be properly post-processed, such as removing burrs, cleaning, checking dimensions, etc., to meet the requirements of subsequent processing or use.
Selection of laser power
Laser power is an important factor affecting the cutting effect. Too high power may cause excessive melting and burning of the material, affecting the cutting quality; too low power may cause slow and incomplete cutting. Therefore, it is necessary to select the appropriate laser power according to the characteristics and thickness of the material.
Control of cutting speed
The cutting speed directly affects the cutting efficiency and quality. Too fast speed may lead to incomplete cutting, and too slow speed will affect production efficiency. Therefore, it is necessary to reasonably control the cutting speed according to the characteristics of the material and the laser power.
Adjustment of focal position
The focal position determines the power density of the laser beam on the surface of the material and has an important influence on the cutting effect. Generally, the closer the focal position is to the surface of the material, the better the cutting effect. However, a focal position that is too close may cause the laser beam to diverge and affect the cutting accuracy. Therefore, it is necessary to reasonably adjust the focal position according to the actual situation.
Selection and control of auxiliary gas
Auxiliary gas plays a key role in the laser cutting process, which can help remove melted or vaporized materials and improve cutting speed and quality. Different materials and cutting requirements require the selection of appropriate auxiliary gases, such as oxygen, nitrogen or argon. At the same time, it is also necessary to control the pressure and flow of the gas to obtain the best cutting effect.
