In fact, plasma arc cutting is a processing method that uses the heat of a high-temperature plasma arc to locally melt (and evaporate) the metal at the incision of the workpiece, and removes the molten metal by the momentum of high-speed plasma to form an incision.
Commonly used plasma arc working gases are argon, hydrogen, nitrogen, oxygen, air, water vapor and some mixed gases. Plasma cutting machines are widely used in automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, construction machinery, steel structures and other industries. It can be used in the case of cutting, and can be used for various metal materials with different properties, including stainless steel, alloy steel, carbon steel, copper and other non-ferrous metal materials.
Plasma cutters can cut sheets into complex shapes as needed. Its features: stable, reliable, lightweight, energy-saving, noise-free, fast cutting speed, smooth cutting, no need to polish. The operation method is as follows: Turn on the power switch and set the power switch to the ON position. At this time, the fan starts to rotate, and the meter screen displays the set current value. Adjust the air pressure knob to the desired pressure and open the compressed air valve. Press the control button on the cutting gun, the solenoid valve will act, and the high-frequency arc discharge sound can be heard in the machine. At the same time, gas should flow out from the nozzle of the cutting gun, and plasma arc should be ejected from the nozzle of the cutting gun.
According to the thickness of the workpiece to be cut, set the corresponding cutting current. After the copper nozzle of the cutting gun is 2mm away from the workpiece, press the button on the cutting gun to ignite the arc, and the high-frequency arc ignition spark in the machine disappears immediately, and the cutting can be started at this time.
The plasma cutting machine can cut various metals that are difficult to cut by oxygen cutting with different working gases, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel), the cutting effect is better; its main advantage is that it cuts metals with small thicknesses When cutting, the plasma cutting speed is fast, especially when cutting ordinary carbon steel sheets, the speed can reach 5~6 times that of the oxygen cutting method, the cutting surface is smooth and clean, the thermal deformation is small, and there is almost no heat affected zone!
The working gas that can be used in the development of plasma cutting up to now (the working gas is the conductive medium of the plasma arc, it is also a heat-carrying body, and at the same time removes the molten metal in the incision) has obvious cutting characteristics, cutting quality and speed of the plasma arc. Impact.
The so-called CNC cutting refers to a new control method in which the workpiece instructions (or programs) used to control the machine tool or equipment are given in digital form. When this instruction is provided to the control device of the CNC automatic cutting machine, the cutting machine can automatically cut according to the given order.
CNC cutting consists of two parts: CNC system and mechanical frame. Compared with radical manual and semi-automatic cutting, CNC cutting can effectively control and improve cutting quality and cutting efficiency through the cutting technology, cutting process and automatic control technology provided by the CNC system, that is, the controller. The CNC plasma cutting machine uses a digital sequence to drive the movement of the machine tool. When the machine tool moves, the randomly equipped cutting tool cuts the object. This mechatronics cutting machine is called CNC plasma cutting machine.
