What happens when the laser cuts carbon steel with the wrong focus?

General Use of fiber Laser cutting machine when cutting carbon steel is the use of positive focus cutting, that is, cutting focus on the workpiece above, the focus will be located in the cutting material above.

Carbon steel-choose positive focus cutting reason, for carbon steel oxygen cutting, suitable for the use of positive focus, for the following reasons:

1. The bottom of the workpiece is wider than the upper surface, which is good for slag removal.

2. It is favorable for oxygen to reach the bottom of the workpiece and participate in sufficient oxidation reaction.

3. Within a certain focus range, the larger the positive focus, the larger the plate surface spot size, the more fully pre-heating and heat supply around the slit, the smoother the carbon steel cutting surface, the brighter.

Laser cutting carbon steel focus position of the consequences, if the laser cutting carbon steel focus is not correct will appear the following consequences:

1. Burr

2. Dregs

3. It won't cut through.

Cutting surface rough, laser cutting carbon steel focus position is not produced, how to adjust? It is necessary to test the laser focus position and adjust it according to the shift of the laser focus, so the cutting of carbon steel is usually processed with the positive focus, otherwise the quality of the processed workpiece will be defective, Laser Cutting Machine needs to use different focus mode for different parts. Because of the different types of laser cutting heads and the different ways of focus adjustment, users also need to choose the appropriate laser cutting position according to their own needs, to maximize the maximum advantage of laser cutting machine.
