At present, the laser equipment utilization rate is very impressive, especially the metal laser cutting machine, in recent years show & other; The rocket type & throughout; Development. Because, as a new type of processing in modern manufacturing mode, it broke the traditional processing methods, in a whole new way of cutting/marking plays a major role in all walks of life.

to know who are in the process of metal laser cutting machine processing, should know that it must be used in cutting auxiliary gas, as a result, many users are more concerned about & other; Gas & throughout; This problem. So, today we laser laser equipment factory in China with you to talk about in the process of cutting: why do you want to add auxiliary gas and users how to reasonably use good auxiliary gases.



s: why do you want to add auxiliary gas?

in figuring out how to choose the metal laser cutting machine auxiliary gas, first of all to understand why want to use the function of auxiliary gas and auxiliary gas. After laser cutting industry many years of experience: the use of auxiliary gas in addition to blow away the coaxial slotted in slag, can also cool processing surface, reduce the heat affected zone, cooling focusing lens, prevent dust from entering the lens holder pollution lens and lens overheating; In addition, some cutting gas can also protect the parent metal. Selection of gas pressure and the influence of cutting technology, choose the kinds of auxiliary gas to the cutting performance, such as cutting speed, cutting thickness have influence.

s characteristics of auxiliary gas

metal laser cutting machine can use the main auxiliary gas of oxygen, nitrogen, air and argon these, here we according to different auxiliary gas, as an introduction to the purpose and characteristics of the used only for your reference. Air

1.

air can be provided directly by the air compressor, so the price is very cheap compared with other gases. Although containing about 20% of the oxygen in the air, but the cutting efficiency is much less oxygen, cutting ability similar to nitrogen. Cut surface will appear trace oxide film, but can be used as measures to prevent a coating layer falls off. Incision face yellow.

main applicable materials are aluminum, aluminum alloy, stainless copper, brass, galvanized steel, non-metallic, etc. , but, when cutting products high quality requirements, such as aluminum, aluminum alloy, stainless steel is not suitable for air, because air is parent metal oxide.

2, nitrogen

when some metal cutting will adopt oxygen oxidation film formed on the surface of the cutting, using nitrogen gas to prevent the occurrence of the oxide film could be without oxidation cutting. No cut surface oxide can be welding, direct daub, strong corrosion resistance characteristics, incision face pale.

the board that is mainly used with stainless steel, galvanized steel, brass, aluminum, aluminum alloy, etc.

3, oxygen,

it is mainly used for laser cutting of carbon steel. Use oxygen heat of reaction of large-format improve cutting efficiency at the same time, the oxide film can improve the beam spectrum absorption factor of reflective materials. Incision face black or dark yellow.

the main applicable rolling steel, dissolves in rolling steel structure, mechanical structure with carbon steel, high tension, palette, stainless steel, galvanized steel, copper, copper alloy, etc.

4, argon

argon gas is inert gas, used to prevent oxidation in laser cutting machine for cutting and nitride, also used in the welding, compared with other gas processing, the price is high, the corresponding increase the cost. Incision face pale.

the main applicable material is titanium, titanium alloy, etc.

s the choice of auxiliary gas

in the above content, many gas can be common use, the key to consider cutting costs and demand for products, such as cutting stainless steel materials, as for the product quality or surface quality is not very high requirements, such as cutting late products also need to process after spray paint and other craft processing, can use air as cutting gas, can decrease the cost of many. When cutting the product is the final products, no follow-up process, you need to use protective gas, such as technology products, etc. Therefore, in the process of cutting blanking must be done according to the characteristics of the product gas.

China laser equipment factory professional laser equipment manufacturers, products include pipe laser cutting machine, laser marking machine, the purple lights, fiber laser cutting machine, and so on.
