Lens cleaning and auxiliary gas analysis of fiber laser cutters

Laser cutting machine application in various industries, in the application of essential is to do a good job of lens cleaning, in addition to cutting when many are also using auxiliary gas to operate, so here we will generally face two major problems, for this situation we have made the following summary, hoping to help you.

Question 1: How to clean up the fiber laser cutter lenses:

The first step is to blow off the floats on the original surface with a blow balloon, especially the lenses with tiny particles and flocs on the surface, and do not use compressed air on the production line, as these airwill contain oil mist and water droplets, which will deepen the contamination of the lenses.
In the second step, pure acetone cleans the lenses slightly. The cotton ball with acetone must be cleaned under the light and made a ring-shaped movement. Cotton swabs are dirty and must be replaced. Cleaning needs to be done once to avoid creating ripples.   If the lens has two coated surfaces, such as a lens, each face needs to be cleaned in this way. The first side needs to be placed on a clean sheet of lens paper for protection.
If acetone does not remove all dirt, clean it next with acid vinegar. Acid vinegar is cleaned using the dissolution of the dirt to remove the dirt, but does not cause harm to optical lenses. This acid vinegar can be experimental (diluted to 50 strength), or home white vinegar containing 6 acetate. The cleaning procedure is the same as acetone cleaning, and then acetone is used to remove acid vinegar and dry lenses, when frequent cotton balls are changed to completely absorb acid and hydrates. Until cleaned.

Question two: Auxiliary gas on the fiber laser cutting machine cutting what role, fiber laser cutting machine cutting using auxiliary gas mainly has the following four points:
1, most of the use of air, or oxygen, and nitrogen, the first purpose is to blow away residual waste, to achieve the best cutting effect.
2, the use of gas to chase away metal slag at the same time, protect the lens, to avoid slag attached to the lens, affecting the quality of cutting.
3, the use of nitrogen cutting, can effectively achieve the cutting surface clean, no burrs without hanging slag effect, belongs to the fine cutting.
4, the use of oxygen cutting, oxygen can be fueled, with the material to produce a reaction to increase the cutting speed.

The above is the main problem facing the fiber laser cutting machine at present, generally in the choice of auxiliary gases generally choose nitrogen, nitrogen or oxygen, of course, we can make the relevant choice according to the specific situation, only to make the relevant choice can be truly understood.
