CNC plasma cutting machineCombined with an easy-to-use numerical control system, the high-speed airflow ionization of the nozzle at high temperature is used to form an electrical conductor. When the current flows, the electrical conductor forms a high-temperature plasma arc, the metal of the workpiece incision is locally melted (and evaporated) by the heat of the arc, and the molten metal is removed by the power of the high-speed plasma gas flow to form the incision. The slender and stable plasma arc formed by the annular gas flow technology ensures that all conductive metals can be cut smoothly. So, let's take a look at the use of CNC plasma cutting machine methods and skills.

The use of CNC plasma cutting machine

When using the CNC plasma cutting machine, the cutting quality is unstable, and the consumables are replaced frequently. More users find that the use specifications of the CNC plasma cutting machine are not enough when using the operation, and at the same time, they do not pay enough attention to some details.

The following summarizes the daily use skills of several CNC plasma cutting machines, hoping to bring you convenience.

1. Cutting starts from the edge

Don't cut the hole, try to cut from the side. Taking the edge as a starting point will extend the life of the wearing parts. The correct method is to aim the nozzle directly at the edge of the workpiece and then start the plasma arc.

2, reduce unnecessary "arc" (or arc wire) time

Nozzle and electrode consumption is very fast when starting an arc, and the torch should be placed within walking distance of the cut metal before starting.

3. Do not overload the nozzle

When an overload is applied to the nozzle, I .e. the actuating current of the nozzle is exceeded, the nozzle will be damaged immediately. The current intensity should be 95% of the operating current of the nozzle. For example, set the amperage of a 100A nozzle to 95A.

4. Adopt reasonable connection and separation

According to the requirements of the instruction manual, use a reasonable cutting distance. The cutting distance is the distance between the cutting nozzle and the surface of the workpiece. When perforating, try to use twice the distance of the conventional cutting distance or the maximum height of the plasma arc energy transmission.

5. The perforation thickness should be within the allowable range of the mechanical system

The CNC plasma cutting machine cannot drill holes in steel plates that exceed the working thickness. The thickness of ordinary holes is 1/2 of the thickness of ordinary cutting. Keep the torch and consumables as clean as possible. Any dirt on the torch and consumables will seriously affect the function of the plasma system. When replacing consumables, put them on clean velvet, carefully check the connecting ribs of the torch, and clean the electrode contact surface and nozzle with hydrogen peroxide cleaner.

CNC plasma cutting machine cutting speed on cutting quality is different

The combination of CNC plasma cutting machine and plasma power supply is called CNC plasma cutting machine. Plasma cutting is prone to cracks, and there are many reasons for cracks. Generally, the optimal cutting speed range of the CNC plasma cutting machine can be selected or tested according to the instructions of the equipment, but according to the thickness of the cut workpiece, the different materials, the melting point, the thermal conductivity, the surface tension after melting and other factors.

The cutting speed of the CNC plasma cutting machine also changes accordingly, mainly as follows.

1. The CNC plasma cutting machine can improve the quality of the cut when the cutting speed is appropriately increased, that is, the cut is slightly narrowed, the surface of the cut is more flat, and the deformation can be reduced.

2. When the cutting speed is too fast, because the cutting line energy is lower than the required amount, the jet cannot blow away the melted cutting melt in time during the cutting process, forming a large backward traction amount. As the incision is stained with slag, the surface quality of the incision Decreased.

3. When the cutting speed of the CNC plasma cutting machine is too low, the cutting place is the plasma arc anode. In order to maintain the stability of the arc itself, the anode spot or anode area must find a place to transfer current near the slit closest to the arc, and at the same time transfer more heat in the radial direction of the jet. The melted material on both sides of the slit gathers and solidifies at the bottom edge, forming scum that is difficult to clean, and the top edge of the slit is heated and melted, form a fillet.

4. When the cutting speed of the CNC plasma cutting machine is extremely low, the arc even disappears because the incision is too wide. Therefore, good cutting quality and cutting speed are inseparable.

The above is the use of CNC plasma cutting machine. If you need to know more, you can contact us at any time! Our company has many years of experience and looks forward to your joining at any time.

The CNC plasma cutting machine is combined with an easy-to-use CNC system, which uses the high-speed airflow sprayed by the nozzle at high temperature to form a conductive body. When the current flows, the electrical conductor forms a high-temperature plasma arc, the metal of the workpiece incision is locally melted (and evaporated) by the heat of the arc, and the molten metal is removed by the power of the high-speed plasma gas flow to form the incision. The slender and stable plasma arc formed by the annular gas flow technology ensures that all conductive metals can be cut smoothly and economically.
