The reasons for the power drop of cutting machine

Why the power of fiber laser cutting machine drops?today we will talk about the reasons for the power drop of cutting machine.It is not necessarily the problem of the laser. Let’s analyze the reasons for the power drop of the fiber laser cutting machine.

 

Focus area

The focus position will affect the precision of laser cutting, especially the spot diameter at the focus point. The diameter of the focal spot must be as small as possible to create a narrow slit. The diameter of the focal spot is directly proportional to the focal depth of the focal point lens. The smaller the focal depth of the focal point lens, the smaller the focal spot diameter.

Distance between nozzle and workpiece

The distance between the nozzle and the workpiece also affects the power reduction of the fiber laser cutting machine. Too far will cause unnecessary waste of kinetic energy, and too close will affect the dispersing ability of splash cutting products. The suitable distance is 0.8 mm. In addition, the fiber laser cutting machine mainly cuts uneven workpieces through subsequent adjustments. The height of the nozzle and the workpiece must be consistent during operation.

Cutting speed

The cutting speed has a great influence on the power of the fiber laser cutting equipment, and the cutting speed is proportional to the power of the fiber laser cutting machine. At the same time, the cutting quality is relate to the quality of the laser beam and also to the characteristics of the laser beam focusing system, that is, the size of the laser beam after focusing has a great influence on the laser cutting quality.

Auxiliary gas

The size and pressure of the auxiliary gas also affect the power of the fiber laser cutting machine. The auxiliary gas is preferably compressed air or an inert gas. If the thickness of the processed material increases or the cutting speed is slow, the air pressure should be appropriately reduced. Cutting with a lower air pressure can prevent frost on the cutting edge.

Laser power

If the first few items are excluded, consider the decrease in laser power. After any equipment is used for a long time, some parts will deteriorate.And  laser is the core and most important part of metal laser cutting machine, and its power will decrease after long-term use. In addition to the above points, the performance, size and thickness of the processed material will also affect the power reduction of the fiber laser cutting machine.
