When cutting machine processing metal, using a wide range of material is stainless steel and carbon steel, compared with aluminium alloy, brass, has a highly reflective metal, both metals better light absorbing, thus cutting used more widely.
the cutting machine with powerful function, in the processing of stainless steel and carbon steel will be, what different, what material is suitable for the cutting machine cutting processing?
a big different, cutting process
use cutting machine processing stainless steel, stainless steel containing 10%
20% of chromium, iron and chromium are prone to oxygen cutting the exothermic reaction, including chromium oxide have prevent oxygen into the internal features of molten material, and reduce the amount of oxygen the melt into the layer, incomplete melting layer oxidation, reduction reaction, to lower cutting speed.
when using cutter machining of carbon steel, usually using oxygen as aided gas, more than 99% on the low carbon steel cutting is iron, iron oxide reflect also can produce a large amount of heat, using oxygen as auxiliary, can reduce the demand for energy, and the oxide of low viscosity, melting point to adhere to the surrounding steel adhesion is low, the slag is also very easy to oxygen blown away, leaving a smooth section of no residue.
2, different material and processing skills stainless steel mirror, sheet to prevent severe burns, need sticker.
Although there is a film protection, edge or there will be a little burns.
At this point, it is necessary to strictly control in the process of machining cutting process parameters, maintain the good corrosion resistance of this kind of material.
Affect the cutting quality of the stainless steel the important technical parameter is cutting speed, power, oxygen pressure and focus.
with the enhancing power of cutting machine, cutting machine can process more and more thick carbon steel and low carbon steel in cutting thick, you need to use more large diameter nozzle and low oxygen pressure, to prevent cutting will burn out the cut edge.
compared with low carbon steel, stainless steel, the cutting power and oxygen pressure is higher, and stainless steel cutting while achieve satisfactory cutting effect, but it is hard to get completely non sticky residue cutting seam.
Using inert gas as auxiliary gas cutting stainless steel can be obtained without oxidation trimming, directly used to welding, but its cutting speed compared with oxygen as aided gas be reduced about 10%.
compared to the traditional processing way, cutter machining efficiency is higher, can achieve mass production, and application more and more widely in the processing of stainless steel, carbon steel, two kinds of metals are suitable for cutting processing, but the machining efficiency and machining quality, presented by the device requires trial and error adjustment to achieve good.
