What are the reasons for saw teeth during laser cutting?

Metal laser cutting machine is used in the high-frequency Sheet Metal Processing industry, with the characteristics of good cutting effect and high surface smoothness, and is deeply loved by the sheet metal processing industry. The popularization of metal laser cutting machines cannot be separated from the improvement of technology by major laser equipment manufacturers. Good equipment manufacturing technology and branded accessories are the quality assurance of laser cutting machines. In daily production, various problems may arise, such as jagged teeth during processing. Why does this situation occur?

1. Parallelism

If the parallelism of the laser cutting machine is not properly installed, the equipment will become unstable during the processing, causing vibration and saw teeth in the cross-section of the processed material.

There are two vibration modes for metal laser cutting machines. One is the vibration of the equipment itself during the cutting process, which affects the cutting effect. 2、 External equipment issues, such as exhaust fans, water tanks, etc. Easy to cause equipment vibration.

2. Gear related aspects

When the tooth base is clamped, it can also cause serrations in the machining section.

3. The guide rails are not parallel

Sometimes the guide rails are not parallel, and the processing equipment may get stuck, so there may also be serrations in the cutting section.

4. Improper fixation of the lens

When the lens is not fixed correctly, the device will shake the lens during operation, the beam will vibrate, and the cutting part will have jagged teeth.

During long-term use, the slider of the metal laser cutting machine will wear out, and foreign objects will appear on the inner ball, causing the guide rail to vibrate during operation and resulting in sawtooth problems after processing.

When we see the sawtooth problem of metal laser cutting machines, we can hold the laser head with our hands to prevent it from shaking. If there is no sawtooth problem after holding it down with your hand, it must be a sliding problem; If it still occurs, it is necessary to check accessories such as belts and gears. If this problem occurs in the new machining process, it is necessary to consider whether the installation is incorrect or if the control driver does not match the motor.
