How to cut high-quality sheet at the best speed?

Fast cutting speed is a major advantage of laser cutting, and it is also an important reason why many sheet metal processing users choose laser cutting machines.

The power of the laser will affect the speed at which the laser equipment cuts the sheet, and the cutting speed of the laser equipment will affect the cutting quality of the sheet. Under the condition of certain laser power, there is an optimal cutting speed range. Too fast or too slow speed will affect the surface flatness of the cutting material.

Cutting too fast

1. The laser beam and the material are in contact with each other for a short time, which may cause inability to cut and sparks.

2. Some areas can be cut off, but some areas cannot be cut off.

3. The entire cutting section is delaminated, and the cutting section presents diagonal stripes (stainless steel).

4. The lower part produces melting stains, which seriously causes the plate to be unable to be cut in time (carbon steel).

Cutting speed is too slow

1. The interaction time between the material and the laser increases, resulting in the over-melting of the cut sheet, and the cutting section is rough.

2. The slit will be widened accordingly, causing overburning in the smaller rounded or sharp corners, and the ideal cutting effect cannot be obtained.

3. The cutting efficiency is low, which affects the production capacity.

Cutting speed judgment method

1. Reasonable cutting speed: the cutting spark spreads from top to bottom, the cutting surface is stable, and there is no slag in the lower part;

2. The cutting speed is too fast: the cutting spark is inclined;

3. The cutting speed is too slow: the cutting sparks do not spread and are less, but condense together.
