High Precision Metal Plasma Cutting Machine

High Precision Metal Plasma Cutting Machine
Product Details

   This machine adopts integrated design as well as a combination of CNC,mechanical transmission and thermal cutting. That makes it to be a high technology, high precision and high reliability cutting machine. Excellent human interface guarantees the easy operating and quick processing for various workpiece.

    Plasma cutting is a processing method that utilizes the heat of a high temperature plasma arc to melt or partially melt (and evaporate) a metal portion at a workpiece cut and to remove molten metal by high-speed plasma momentum.

Machine structure
1. The frame adopts all-welded structure, which is firm and reasonable, easy to operate and durable.
2. Cutting speed and high precision. The cutting mouth is small, neat and has no slag. On the basis of the traditional numerical control system, the control method for cutting is improved, and the secondary dressing processing is avoided.
3. Suitable for low carbon steel, copper, iron, aluminum, galvanized, titanium and other metal plates.
4. The CNC system configuration is high. Automatic arc ignition, stable performance, the success rate of arc ignition is more than 99%.


Working principle
Plasma is a gas that is heated to a very high temperature and is highly ionized. It transfers the arc power to the workpiece. High heat causes the workpiece to melt and be blown off, forming a working state of plasma arc cutting.
After the compressed air enters the torch, two channels are distributed from the air chamber to form a plasma gas and an auxiliary gas. The plasma gas arc acts to melt the metal, while the auxiliary gas cools the various components of the torch and blows away the molten metal.
The cutting power supply consists of two parts: the main circuit and the control circuit. The electrical principle: the main circuit includes a contactor, a three-phase power transformer with high leakage resistance, a three-phase bridge rectifier, a high-frequency arcing coil and a protection component. The high-leakage resistance is caused by the steep external power characteristics. The control circuit completes the entire cutting process through the push button switch on the torch:
Pre-ventilation - main circuit power supply - high frequency arc ignition - cutting process - interest arc - stop.
The power supply of the main circuit is controlled by the contactor; the short-circuit of the gas is controlled by the solenoid valve; the control circuit controls the high-frequency oscillator to ignite the arc, and stops the high frequency after the arc is established.
In addition, the control circuit also has the following internal locking function: the thermal switch action, stop working.
