Tube laser cutting 3D

3D cutting of pipes and profiles by combustion of the material by means of high intensity light generated in a laser generator.

The process

A laser beam [1] is generated and then directed to the cutting head [2] using mirrors. Where the beam is focused with a lens [3] and a cutting gas [4], which usually consists of oxygen or nitrogen, is supplied to the cutting head and surround the laser beam during the cutting process. The laser beam is focused [5] on the workpiece [6], which heats up, melts and partially vaporizes the material and a cutting section is created.

The molten material formed during the cutting process is blown away by the cutting gas. This protects the lens from splashes from the cutting area and also makes the laser beam free of vapors that could absorb parts of the laser beam.

In this method, the cutting head is guided by 3 axes in combination with feed and rotation of the workpiece.

Cutting at an angle to the surface is always slower, which means that it should only be used where it is really needed.

Advantages and disadvantages
In comparison with alternative methods
Can cut angled cuts
Spray inside the tube
Angled cutting of the surface is slower
When tilt takes place away from the chuck centering tolerance becomes worse.
