The best cutting range and cutting speed of portable CNC cutting machine
June 21, 2018
The famous American quality manager said that the 20th century is the century of productivity, the 21st century is the century of quality, and quality is the most effective weapon for occupying the market peacefully. The industry of cutting machines is very useful in such evaluations. Details:/
The best cutting range of the portable CNC cutting machine mainly shows that: the moderate cutting speed can improve the quality of the incision, that is, the incision is slightly narrowed, the incision surface is more even, and the deformation can be reduced, and the cutting line speed can make the cutting line energy faster. Below the required amount, the jet in the slit cannot quickly blow off the molten cutting melt to form a large amount of back drag, accompanied by slag along the cut, and the quality of the cut surface is reduced.
The optimal cutting speed range of the portable CNC cutting machine can be selected according to the equipment instructions or determined experimentally, because of the thickness, material, melting point, thermal conductivity, and surface tension after melting. Corresponding changes. When the cutting speed is too low, because the cutting point is the anode of the plasma arc, in order to maintain the arc itself, the freckles or anode area of the anode must find the conduction current place around the cutting closest to the arc and at the same time, To transmit more heat, so that the incision is widened, the melted material on both sides of the incision will be extracted and solidified at the bottom edge, forming a slag that is not easy to clean, and the upper edge of the incision is rounded due to excessive heating and melting.
