Cutting machine using air cutting can reduce the cost?

As the processing industry increasingly competitive, how to improve efficiency, reduce cost a matter of concern to most users. Cutting machine with cutting speed, material deformation small, processing precision higher advantages, quickly became the mainstream. The application of high power, but also greatly improve the efficiency of the machining, sheet cutting speed limit has been able to challenge the mechanical performance of the control limits, the thick plate cutting process has been breakthrough.





cutting machine commonly used cutting auxiliary gas has three oxygen, nitrogen, air. But as a result are more expensive than nitrogen, oxygen, compressed air, nitrogen, oxygen, and the price rises year by year, so using air as auxiliary gas cutting, can greatly reduce the cost of production.

oxygen is mainly used for carbon steel cutting, its principle is oxygen oxidizing reaction with the metal, release huge amounts of heat oxidation, at the same time, a certain pressure will blow out the oxides and slag from the reaction zone, the formation of incision in the metal. Due to oxidation produced a large amount of heat in the process of cutting, so don't need too much power, but cutting Angle easily burnt.

nitrogen is mainly used for stainless steel and aluminum plate cutting, but also can cut a certain thickness of carbon steel plate, the higher the power, can cut the carbon steel plate thickness. Nitrogen gas cutting, relying on the energy of the melt metal, high pressure during the melt blown away and make sure to avoid unreasonable chemical reaction. Can get more light on the stainless steel, aluminum plate cutting effect, the section that sharp-angled effect is better.

air itself exists in the atmosphere, use air compressor to compress it to storage tanks, after filtering, cooling and drying device, remove the oil and water in the air, can be used. The cutting principle of air and nitrogen is similar, but because of containing about 20% of the oxygen in the air, so can make up the lack of oxygen and nitrogen to a certain degree.

the cutting speed, not the advantage of air and nitrogen, but both in 8 mm and the thickness of the following is much higher than in oxygen. Oxygen cutting carbon steel section, of course, the brightness and bottom surface finish, will be more better than air and nitrogen.

the comprehensive consideration, the requirements under the condition of relatively loose, air cutting has a large cost advantage. But beware, the use of air cutting, the person must ensure that the air filter, air compressor, the person who need regular maintenance. If into the cutting head of containing oil and water in the air, can cause to protect lens fogging in a short period of time, influence the cutting quality, then if not timely replacement protection glasses, under high power beam irradiation may also result in higher internal temperature of the cutting head, may cause damage to internal lens.

for was a big factory, with high power cutting machine, air cutting for its higher efficiency and lower cost, the income is far higher than the cost of secondary processing of workpiece. But for small processing plants, air cutting can not cut down the cost. Whether to adopt air cutting, therefore, need to decide according to their output.
