Compared with traditional metal cutting equipment, laser cutting machine equipment has the advantages of fast speed, high accuracy, and high efficiency. Therefore, many enterprises have chosen laser cutting machines to process stainless steel products. However, if the product is improperly processed, the consequences cannot be ignored. It will affect product quality and cause the product to be unqualified. Jinan Youben Machinery has organized some methods for improving the processing quality of fiber laser metal cutting machines for you, hoping to be helpful for you in operating the machine.
Fiber laser cutting of stainless steel
What are the factors that affect the machining accuracy of metal laser cutting machines?
Compared with traditional metal cutting processes, metal laser cutting machines have higher machining accuracy, better cross-sectional effect, and no need for secondary processing. This is also the reason why many enterprises choose metal laser cutting machines. However, many companies have found that the cutting accuracy of fiber laser cutting machines is sometimes not ideal, which affects the subsequent processing process. What are the factors that affect machining accuracy?
1. Processing materials
When using laser cutting machines to process metal, the cutting accuracy of different materials varies. Even for the same material, if the composition of the material is different, the cutting accuracy will also be different. Therefore, the material of the workpiece also has a certain impact on the accuracy of laser cutting. Generally speaking, the smoother the material, the higher the machining accuracy.
Therefore, when processing different metal materials, samples can be made in advance to find the most suitable parameter settings for this type of material.
2. Laser beam shape
The laser beam of a metal laser cutting machine is conical, so the cutting seam is also conical. The shape of the laser beam is also the main factor affecting the cutting accuracy of metal laser cutting machines. The smaller the spot after laser beam convergence, the smaller the cutting seam, and the higher the machining accuracy.
Under this conical laser beam condition, the thicker the workpiece, the lower the accuracy, and therefore the larger the incision. Therefore, when processing metals with different thicknesses, it is necessary to choose the appropriate laser power to achieve better results.
3. Workbench accuracy
During laser metal cutting machine processing, the workbench vibrates with the vibration of the laser head. The higher the cutting accuracy, the higher the cutting accuracy when the high-precision workbench is paired with a stable linear guide rail and stepper motor; If the workbench is uneven or for other reasons, it can also affect the processing accuracy of the fiber laser cutting machine.
4. Auxiliary gas and nozzle
In the process of laser metal cutting machine processing, auxiliary gases and nozzles play a role in cleaning and controlling cutting speed. The uneven pressure and temperature in the airflow can cause changes in the density of the airflow field, drying up the focusing of the beam energy, causing refocusing or beam divergence, and affecting the accuracy of metal cutting.
When fiber laser cutting machines process metal, the quality of metal cutting is affected by various factors. As long as adjustments are made according to specific reasons, these problems can be solved. If you encounter an uncontrollable malfunction when using a laser cutting machine, you should first contact the manufacturer of the laser cutting machine and seek the help of professional technical personnel, which can save time and effort. After a period of operation, you can accumulate more experience in operating laser cutting machines and produce higher quality metal workpieces.
