High Quality CNC Plasma Cutting Machine

What is a cnc plasma cutter?

CNC plasma cutters are computer numerical controlled metal cutting machines that use plasma torch to cut metals into different profiles and shapes with CNC controller, including mild steel, stainless steel, carbon steel, galvanized steel, hot rolled steel, cold rolled steel, iron, brass, copper, alloy, aluminum, bronze, and titanium.  A CNC plasma kit is composed of machine frame, plasma CNC controller, plasma power supply, plasma torch, blade or sawtooth plasma table, driver, motor, plasma CNC cutting system, plasma CNC cutting software, guide rail, ball screw, optional parts and consumble parts.  CNC plasma cutter is also known as plasma CNC cutter, CNC plasma table, CNC plasma cutting machine, CNC plasma cutting table, CNC plasma cutting system, CNC flame cutting machine, CNC oxy-fuel gas cutting machine, CNC flame plasma cutting machine, CNC oxy fuel cutting machine, CNC plasma & oxy-fuel cutting machine.

The solution to the unstable arc voltage of the CNC plasma cutting machine.

In the normal use of a CNC plasma cutting machine, arc voltage may be unstable. Solution: Always check the spark generator's discharge electrode to keep its surface flat, adjust the discharge electrode gap of the spark generator (0.8~1.2mm) in time, and replace the control board if necessary.

Under normal circumstances, the working time of the spark generator is only 0.5~1s. The reason for the automatic arc interruption is generally due to the imbalance of the control circuit board components. The discharge electrode gap of the spark generator is different.

The spark generator cannot automatically interrupt the arc.

When the CNC plasma cutting machine works, the plasma arc is first ignited. The gas between the electrode and the nozzle's inner wall is excited by a high-frequency oscillator to produce a high-frequency discharge. The negative gas is partially ionized to form a small arc. This small arc is subjected to compressed air. The spark generator's role is to spray from the nozzle to ignite the plasma, which is the main task of the spark generator.

In addition to the above reasons, the cutting speed is too slow, the perpendicularity of the cutting torch and the workpiece during cutting, and the operator's knowledge of the plasma cutting machine, etc., affect the instability of the plasma arc, users should pay attention to these aspects.

Features of CNC plasma cutting machine

Plasma cutting has a wide cutting area and can cut all metal plates, with fast cutting speed and high efficiency, and the cutting speed can reach more than 10m/min. The use of fine plasma cutting has made the cutting quality close to the level of laser cutting. At present, with the maturity of high-power plasma cutting technology, the cutting thickness has exceeded 150mm, which has broadened the cutting range of CNC plasma cutting machines. Desktop CNC cutting machine equipment can effectively improve the efficiency and cutting quality of plate cutting, reduce the labor intensity of the operator, and has a great advantage in the field of thin plate cutting, and is widely used in the duct processing and manufacturing industry.
