Precautions and solutions for metal plate fiber laser cutting machine
With industrialization entering the stage of gradual development, market demand and industrial production have gradually increased. Ordinary metal processing equipment generally cannot meet the production requirements of industrialization. Therefore, after a period of development, many people Will choose domestic metal plate fiber laser cutting machine. Generally, carbon steel plates within 20 mm are cut, or stainless steel materials within 10 mm are cut, which are used in many industries such as metal processing, automobile industry, and machinery manufacturing.
The lenses used in domestic metal plate fiber laser cutting machines are divided into many types, including focusing lenses, protective lenses, etc., which will inevitably be polluted during their work, such as water pollution or dust pollution. The laser lens must be cleaned to ensure its stability. In the process of cleaning the lens, the purpose is to remove the contamination of the lens, and not to cause further pollution and damage to the lens. During the installation and cleaning of the lens, any sticky matter, or even oil droplets printed on the nails, will increase the absorption rate of the lens and reduce the service life.
As summer approaches, the temperature begins to rise rapidly. As a cutting equipment, the continuous heating of the metal plate fiber laser cutting machine will cause certain damage to the equipment and affect the normal operation. In order to avoid the problem of heating after the equipment is working, the following matters need to be paid attention to when using the domestic metal plate fiber laser cutting machine:
- Because it achieves the purpose of cooling through water cooling, it is recommended that operators control the water temperature difference within 10 degrees.
- Check whether the working pressure of the lower water cooler is normal. It is recommended to consult the equipment manufacturer for the specific parameters of the water cooler in advance, and then check.
- In summer, the temperature is relatively high, and the cooling water must be distilled water or pure water, which should be replaced regularly. When cleaning the scale, contact the manufacturer in advance for guidance.
- When working, metal dust will be generated, so check the fan and clean the fan. Dust can also affect the work of electrical appliances, and cleaning electrical cabinets is also a top priority.
How to avoid overburning of metal plate fiber laser cutting machine
metal plate fiber laser cutting machine is a laser cutting machine that uses a fiber laser generator as a light source. Used in sheet metal processing, aviation, aerospace, electronics, electrical appliances, subway accessories, automobiles, food machinery, textile machinery, construction machinery, precision accessories, ships, metallurgical equipment, elevators, household appliances, craft gifts, tool processing, decoration, advertising , metal external processing, kitchen utensils processing and other manufacturing and processing industries. When we use the metal plate fiber laser cutting machine, we will not pay attention to the phenomenon of over-burning, so how should we avoid it? Let’s have a look!
1: Corner plus cooling point
When cutting sharp-angled metal sheets, the place where over-burning is more likely to occur is often at the sharp corner. Over-burning will cut the sharp corner into a round shape. At this time, a cooling point can be added to the sharp corner and pause at the sharp corner. One moment, take a breath.
2: Use a high-power laser
metal plate fiber laser cutting machines can use higher power lasers when cutting carbon steel. The bright surface cutting process can effectively avoid over-burning, and this cutting process can cut burr-free and brightly cut finished products.
Three: cutting with nitrogen
In the sheet metal cutting with oxygen as the auxiliary gas, it can be switched to deuterium gas for cutting. During nitrogen cutting, the material is completely melted by laser energy, and nitrogen is blown out of the kerf and inappropriate chemical reactions are avoided. The temperature in the melting point area is relatively low, coupled with the cooling and protective effect of nitrogen, the reaction is stable and uniform, and the cutting quality is high. The section is fine and smooth, the surface roughness is low, and there is no oxide layer.
Four: Increase the air pressure
When using the metal plate fiber laser cutting machine to process aluminum alloy and stainless steel, the auxiliary gas used is nitrogen or air, and edge burning will not occur during the cutting process. However, due to the high temperature of the material inside the small hole, the slag hanging on the inside will be more frequently. In this case, burrs and dross can be reduced by increasing the pressure of the auxiliary gas.
