What causes the Sawtooth phenomenon of the laser cutting machined section?

Laser cutting sheet metal is very efficient. What causes the Sawtooth phenomenon of the machined section?

1. Parallelism not good

If the laser machine is installed, the parallelism is not enough. The equipment will be shaken during processing, and the machined section will be jagged.

2. Equipment vibration

Interfered with external equipment. For example, the exhaust fan, water tank, etc. are placed too close to make the laser cutting machine vibrate.

3. The guide rail is not installed properly

The Y-direction rails are not installed in parallel, and jamming may occur during processing of the equipment. The cut section will appear jagged.

4. The lens is not fixed

During the operation of the laser cutting machine, the lens shakes, causing the beam to vibrate. The final cut section appears jagged.

5. Equipment worn out

The practical time of the laser equipment is gone, and many parts will wear out. For example, if the slider wears, the guide rail will vibrate when it moves, and the machined section will appear jagged.

Now summarize:

When the cross-section appears to be jagged, the laser head is manually fixed to ensure the processing is safe, so that the laser head is not shaken. If there is no aliasing after fixing, check the slider. If the phenomenon does not improve, check other accessories and factors. If the newly purchased equipment has such a problem, it can almost be concluded that the parallelism is insufficient when it is installed.
