THE SPEED SETTINGS OF CNC PLASMA CUTTERS:
Because the thickness of the material, different raw materials, melting point, thermal conductivity and melting after the outer tension and other factors, cutting speed also changes accordingly, so the best cutting speed can be selected according to the equipment or with experiments to determine, its performance is as follows:
When the cutting speed is too low, because the cutting is the anode of the plasma arc, in order to maintain the stability of the arc itself, the anode spot or anode area must be in the nearest cut of the off-arc to find the conduction current local, together will transfer more heat to the radial radial, so that the cut wide, cut off the two sides of the molten data in the bottom edge collection and solidification, constitute not easy to organize the hanging slag, and cut off the upper edge due to excessive heating melting and make the round.
Cutting speed too fast makes the cutting line energy below the required amount, the jet in the cut can not quickly blow off the melted cutting melt immediately and constitute a larger drag volume, along with cutting off the hanging slag, cut off the appearance of the quality of the reduction
A moderate improvement in cutting speed can improve the cut-off quality, i.e. the cut narrows slightly, the cut-off surface is flatter, and together it can reduce deformation.
When the speed is very low, the arc will even subside because the cut is too wide. Thus, good cutting quality and cutting speed are inseparable.
THE SPEED SETTINGS OF CNC PLASMA CUTTERS:
When CNC plasma cutting depends on cutting auxiliary gas is not divided into a variety, different auxiliary cutting gas cutting speed standards are not the same, to air plasma arc cutting, for example, in cutting carbon steel plate, 230A cutting current as the standard, 6mm thickness carbon steel plate cutting speed can reach 3300mm /min more suitable; If the switch to other auxiliary cutting gases, such as pure oxygen cutting, cutting speed is greater, in the same 230A cutting current, although for 6mm thickness carbon steel plate, pure oxygen plasma cutting can be advanced to 3700mm/min, but the cutting speed of 40mm carbon steel plate is only 350mm/min.
Second: there are many factors affecting the quality of plasma cutting, such as empty load voltage and arc column voltage, cutting current, electrode shrinkage, cutting nozzle height and other plasma arc cutting technical parameters, will directly affect the stability of the cutting process, cutting quality and function. Generally speaking, the empty load voltage and arc column voltage, cutting current, electrode shrinkage, nozzle height and other factors are directly affecting the plasma arc of the tightening effect, that is, affecting the temperature and energy density of the plasma arc, and the plasma arc of high temperature, high energy resolution cutting speed, so it can be said that many of the above elements are in essence related to cutting speed. As a CNC cutting equipment, the cutting speed should be improved under the premise of ensuring the quality of the cutting. This not only improves productivity, but also reduces the amount of deformation of the cut part and the thermally affected area of the cut area. If the cutting speed is not suitable, its effect is the opposite, and will make the adhesive slag added, cutting quality is reduced, set up a good numerical control cutting machine above the small details I believe the CNC plasma cutting machine processing efficiency will be more than half the effort.
