Introduction to Plasma Cutting Machine

A plasma cutting machine is an equipment for processing metal materials with the help of advanced plasma cutting technology. Plasma cutting is a processing technique that utilizes the heat of a plasma arc to melt part of the metal. After that, it cut down the metal into a workpiece. In this way, it uses high-speed plasma momentum to remove molten metal to form a cut.

Main Features

Plasma cutting machine with diverse imperative gases can cut a range of metals. It does not matter what type of metals you want to cut like non-ferrous metals (stainless steel, carbon steel, aluminum, copper, titanium, nickel); you can use this machine. The main benefit of using this machine is that the cutting thickness will not be too large. If you want to cut down the big metals, then the plasma cutting speed will be quite fast, especially when it comes to the typical carbon steel sheets. The speed could reach out 5-6 times that of the oxygen cutting method. The cutting surface will be quite smooth. However, thermal deformation will be small. There will be almost no heat-affected zone.

The plasma cutting machine can use a working gas (the working gas is the conductive medium of the plasma arc). It is also a heat carrier. At the same time, the molten metal in the incision must be excluded. The cutting characteristics, cutting quality, and speed of the plasma arc are influences. There are diverse gases that are used for plasma arc working which include hydrogen, argon, oxygen, nitrogen, air, water vapor as well as some mixed gases.

Plasma cutting equipment is widely utilized in automobiles, nuclear industry, engineering machinery, locomotives, chemical machinery, pressure vessels, general machinery, steel structures, and other industries.

Through the safe, easy, effective, multifunctional and environmentally friendly method of obtaining plasma from water vapor, thermal processing (cutting, welding, brazing, quenching, spraying, etc.) of metal with a thickness of 0.3mm or more is available in metal. It is the first in the history of the processing industry.

Working Essence

The plasma product consists of plasma torches as well as chassis. The essence of the working process of the plasma equipment is as follows:

· An arc occurs between the nozzle (anode) and the electrode (cathode), which is present inside the gun.

· The moisture between them is ionized to reach the plasma state. At this time, the ionized vapor is ejected from the nozzle in the form of a plasma beam by the internal pressure. Its temperature is about 8 000 ° С. In this way, non-combustible materials are cut, welded, and other forms of heat treatment.

Machine Design

CNC plasma cutting machine manufacturers are offering diverse types of plasma cutting equipment. The working principle of these machines are almost the same. Right now, we are going to explain a few things about this machinery. Have a look:

1. The frame adopts a fully welded structure. It is sturdy and reasonable, simple to operate, and durable.

2. Fast cutting speed and high precision. The cutting mouth is small and neat, and there is no slag dropping. Based on the traditional numerical control system, the cutting control method is improved.

3. Suitable for low carbon steel plate, copper plate, iron plate, aluminum plate, galvanized plate, titanium gold plate, and other metal plates.
