The Benefits Of A Plasma CNC Machine Plasma Cutting Table

What Is plasma cnc machine?

Plasma cnc machine uses high-temperature, high-speed gas jets at the nozzle to ionize to form electrical conductors. When the current passes, the conductive gas forms a high-temperature plasma arc. The heat of the arc locally melts (and evaporates) the metal at the incision of the workpiece and uses the power of the high-speed plasma flow to remove the molten metal to form an incision. The slender and stable plasma arc formed by the annular airflow technology ensures that any conductive metal can be cut smoothly and economically.

How plasma cnc machine works

plasma cnc is a process in which electrically conductive materials are cut through by means of an accelerated jet of hot plasma. Typical materials that can be cut with a plasma torch are steel, stainless steel, aluminium, brass, copper and other conductive metals. Plasma cutting is widely used in manufacturing, automotive repair and restoration, industrial construction, salvage and scrapping. Due to the high speed and precision of the cuts at low cost, plasma cutting is widely used from large industrial CNC applications to small hobby companies where the materials are subsequently used for welding. Plasma cutting - Conductive gas with a temperature of up to 30,000°C makes plasma cutting so special.

The basic process in plasma cutting and welding is to create an electrical channel of superheated, electrically ionised gas – i.e. plasma - from the plasma cutter itself through the workpiece to be cut, thus forming a finished circuit back to the plasma cutter via an earth terminal. This is achieved by a compressed gas (oxygen, air, inert gas and others depending on the material to be cut) which is blown to the workpiece at high speed through a focused nozzle. Within the gas, an arc forms between an electrode near the gas nozzle and the workpiece itself. This electric arc ionises part of the gas and creates an electrically conductive plasma channel. As the current from the cutting torch of the plasma cutting machine flows through this plasma, it gives off enough heat to melt through the workpiece. At the same time, much of the high-speed plasma and compressed gas blows the hot molten metal away, separating the workpiece.

Pros of plasma cnc machine:

• Fast: no preheating necessary, so the torch can start cutting instantly. With speeds up to 500IPM, it can rival laser cutters based on the type of part.

• Versatile: capable of piercing, complicated cutting and beveling in one process. Plasma cutters can successfully cut any electrically conductive metal up to 6" thick.

• Precise: paired with state of the art software and high accuracy components, the want for expensive secondary operations is eliminated. The torch head is computer controlled, making clean, sharp cuts.

• High Cut Quality: fewer dross and high superiority edges. Tight integration between the cutting torch and software results in high superiority manufacture.

• Easy to Use: while a CNC engine may seem complex, the CNC (computer numerically controlled) software takes most of the guess work out of cutting. With a state of the art package, even a first time worker is capable of creating wonderful outcome.

• Safe: most excellence systems offer an exhaust or down draft system to draw smoke away from the operator.
