Machine of numerical control Plasma Cutting: Air Plasma Cutting introduces

Air Plasma Cutting is a kind of new-style hot cut technology, its working principle is with compressing air is working gas, with plasma of high temperature high-speed arc is heat source, will by the metal of cut the local and fused, metal that uses high speed air current to already will fuse at the same time is blown, form stricture to cut seam. This equipment can be used at all sorts of metals such as steel of stainless steel, aluminous, copper, cast-iron, carbon material cut, not only cut rate is rapid, cut seam level off of narrow, cut, hot influence the area is small, workpiece is out of shape degree of low, operation is simple, and have distinct energy-saving effect. The article is main give with respect to the characteristic of air Plasma Cutting of machine of numerical control Plasma Cutting and blemish the introduction: Plasma air patterning method introduces 1, when cut stainless steel and aluminium, the chromium in oxygen and stainless steel and aluminium have reaction, its cut surface is rougher, be opposite commonly method of this kind of treatment is not used when demand of cut surface quality is higher. Plasma air patterning method with dry compression air regards treatment as gas, basically use at cut carbon steel, also can use at cut stainless steel and aluminium. 2, because air is main,comprise by nitrogen and oxygen, when cut carbon steel, the exothermic reaction of the oxygen in cut and iron was offerred additional quantity of heat, create exterior pulling force at the same time the FeO with low, good liquidity is slaggy, improved the liquidity of metal of the melt in cut, accordingly not only cut rate is rapidder, and cut face is more bright and clean, cut lower edge does not stick broken bits basically, cut face bevel is lesser. Plasma air patterning method basically puts in the following defect: 1, the layer is changed with nitrogen on cut face, the meeting in the welding line when soldering produces air hole, because this is used at soldering cut edge, need to use emery wheel burnish, purify nitrogen changes a layer. 2, as a result of existence oxidation, easy loss of electrode and nozzle, service life is briefer. 3, because reduce airy cost inferior, method of this kind of cut solders in the blame of large quantities of quantities use in the cut of carbolic stencil steel relatively extensive.
