The causes of wave patterns on the cross-section of laser cutting machines

1. Machine vibration
During the cutting process of a laser cutting machine, if it is affected by external factors such as water tanks, exhaust fans, etc., it may generate vibration, resulting in wave marks on the cutting surface.

2. Gear slipping
The slippage between the gear and the gear seat may also cause wavy lines on the machined section.

3. Rail installation issues:
If the guide rails are not installed parallel, or if there is jamming during equipment processing. This situation may also lead to the appearance of wave patterns.

4. Lens locking issue
If the lens is not locked, the machine may vibrate during operation, causing wave marks on the cutting surface.

5. Sliding block wear
Internal wear of the slider or blockage of beads can cause shaking during the cutting process. As a result, wave patterns are generated.

6. Machine parallelism issue
If the machine does not pay attention to parallelism during installation, vibration may occur during operation, resulting in wavy patterns on the cutting surface.

7. Insufficient power
When the laser power is insufficient, the heat affected area during cutting is small. When the thickness of the cutting plate is large, the formation of the molten pool is unstable, which may also cause wave patterns.

8. Unstable light spot
The stability of the laser spot can affect the cutting quality. If the spot is unstable, uneven formation of the molten pool during the cutting process may also result in wave patterns.

It may also be due to unstable light plates, wear caused by long-term operation of laser cutting heads, improper selection of cutting heads, and other factors.
