 Key technology three
The first high cutting pressure zone is next to the nozzle outlet, and the distance from the work piece surface to the nozzle outlet is about 0.5~1.5mm. The cutting pressure Pc is large and stable, which is a commonly used process parameter for cutting handles in industrial production today. The second high cutting pressure zone is about 3~3.5mm from the nozzle outlet, and the cutting pressure Pc is also large, which can also achieve good results, and is beneficial to protect the lens and increase its service life. Other high cutting pressure areas on the curve cannot be used because they are too far away from the nozzle outlet and difficult to match the focused beam.
There are already many laser cutting machines on the market, so customers are faced with a question: how to choose a laser cutting machine? The laser cutting machine is a high-precision equipment, which tends to consume a higher cost, so you must be cautious if the price is lower than the market price. Secondly, you can choose according to the following points:

1) The cutting seam is fine: the cutting seam of laser cutting in the die making industry or packaging industry is generally 0.45mm-1.42mm, corresponding to the thickness of the cutting rules of 2pt, 3pt, 4pt.
2) The cutting surface is smooth: whether the laser cutting surface has burrs or not; in general, YAG laser cutting machines have some burrs, which are mainly determined by the cutting thickness and the gas used. Generally, there are no burrs below 3mm. Nitrogen gas has the best effect, oxygen has the second best effect, and air has the worst effect. The fiber laser cutting machine has the least or no burrs, the cutting surface is very smooth, and the speed is very fast.
3) Look at the deformation of the material: the deformation of the material is very small
4) The size of the power: For the die industry, the main consideration is the output of your own factory. It is not recommended to choose a high-power machine for a small output.
5) The core parts of laser cutting: laser and laser head, because they affect the cutting accuracy of the machine to a certain extent.
Any piece of equipment will experience varying degrees of damage during use, so in terms of repairing after damage, whether the repair is timely and the cost of the repair has become a problem that needs to be considered. Therefore, the purchase is to understand the company's after-sales service through multiple channels, such as whether the maintenance fee is reasonable, and so on.
It is very important to choose a good equipment and a supplier with good after-sales service. The equipment is used for a long time. Although small problems will not lead to major mistakes, it will allow you to invest more money and time in post-maintenance and after-sales services. And human and material resources.
