Plasma arc machining working principle diagram process details of pam.

Plasma cutting machine working principle pdf.

In the plasma arc machining process the material is removed by directing a high velocity jet of high temperature 11000 c to 28 000 c ionized gas on the workpiece. Is passed through a small chamber in which a high frequency spark arc is maintained between the tungsten electrode cathode and the copper nozzle. Working principle of plasma arc machining the principle of plasma arc machining is shown in the figure. And the cutting object material is fused to be cut.

When a solid is heated the molecules start to vibrate more vigorously. The basic principle is that the arc formed between the electrode and the workpiece is constricted by a fine bore copper nozzle. A plasma is a state of matter like a solid liquid or gas. Plasma arc cutting machine with automatic torch travel was used to cut ss304 work.

Working area flat cutting table cutting no collector table stepper motor providing 1 meter of space on each side of the cutting area is enough to operate the cnc plasma cutting machine. Principle of plasma cutting means to focus a lot of. More space is preferable for loading metal plate especially when you load by forklift. This is a cutting system utilizing heat generated by arc discharge between the cutting object material and the electrode inside the torch.

The so called pv duration of inclusion is 100. Although it can be 40 for handhelds which means the following. Working principle of pam. Adding heat to material causes the molecules in it to vibrate or move more quickly.

The plasma arc cutting process is illustrated in fig. Section 2 introduction to plasma cutting plasma cutting basics what is a plasma. In a plasma torch known as the gun or plasmatron a volume of gas such as h2 n2 02 etc. Machine plasma cutting machines use water for cooling so the whole shift can work without interruption.

Atmospheric conditions from the working zone etc. The plasma jet of high temperature and high speed is blown out from the nozzle. 4 minutes of plasma cutting is working and 6 minutes is necessary for it to cool down. The temperature of the plasma is in excess of 20 000 c and the velocity.

Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma typical materials cut with a plasma torch include steel stainless steel aluminum brass and copper although other conductive metals may be cut as well plasma cutting is often used in fabrication shops automotive repair and restoration industrial construction and. Arc discharge heat forms working gas into the plasma state of high temperature. This increases the temperature and velocity of the plasma emanating from the nozzle. Normal table with collect drawer or water table.
