CNC PLASMA
What is Plasma?
The plasma arc cutting process has been in use for over 50 years. It was first developed during World War II when manufacturers needed a reliable welding process for aircraft parts. The method used an inert gas as a barrier to protect an electric arc from oxidation during welding. Over time, engineers refined the process and discovered that narrowing the opening through which the gas passed created a hotter, faster arc. This led to the development of plasma arc cutting as a commercial process, which has been in widespread industrial use since the early 1960s.
Why CNC Plasma is Used
CNC Plasma Cutting is used because it combines speed, accuracy, and the ability to cut a wide range of metal thicknesses in a single automated operation. Engineers and fabricators working with mild steel, stainless steel, aluminium, and other metals find it to be one of the most practical options for production cutting. The CNC system removes the need for manual guiding, which eliminates operator error and delivers consistent results across every part. It is widely used in fabrication shops, engineering units, and manufacturing facilities across Coimbatore, Chennai, Bangalore, Hyderabad, Pune, Kolkata, and Mumbai.
No Skills Required
CNC Plasma Cutting is fully programmed from a CAD drawing. The machine does the cutting automatically, so the operator does not need manual cutting skills. Once the program is loaded, the machine runs the job from start to finish. The key advantages of this approach are:
- Accuracy and Precision across every cut, regardless of shape or complexity
- Efficiency with fast cutting speeds and minimal material waste
- Variety of Materials including MS, SS, Aluminium, Copper, and other metals
Methods
Most of the early development in plasma cutting came from experimenting with gas flow, arc openings, and electrode design. This work led to the creation of a stable plasma arc cutting process that entered commercial use in the early 1960s. At that time, the process was expensive and mainly used by large manufacturers. As the technology developed and costs came down, CNC Plasma Cutting Services became accessible to a much wider range of fabrication and engineering businesses. Today, the process is one of the standard methods used for metal cutting in industrial production.

Frequently Asked Questions
What is CNC Plasma Cutting?
CNC Plasma Cutting is a process where a high-temperature plasma arc is used to cut through electrically conductive metals. The cutting path is controlled by a CNC system programmed from a CAD drawing, giving accurate and repeatable results on every part.
What materials can be cut with CNC Plasma?
CNC Plasma cuts electrically conductive metals, including mild steel, stainless steel, aluminium, copper, brass, and galvanized steel. It is most effective on metals commonly used in fabrication and structural engineering.
What is the cutting thickness range for CNC Plasma?
CNC Plasma can cut mild steel plates from 1 mm up to 50 mm thickness in a single pass. The capacity varies depending on the material type and the machine’s power output.
How accurate is CNC Plasma Cutting?
CNC Plasma Cutting follows the programmed path from a CAD drawing, delivering consistent accuracy across every part. While it is slightly less precise than laser cutting on thin sheets, it is well-suited for structural and fabrication work where speed and thickness capacity matter.
Why is CNC Plasma preferred for thick metal cutting?
CNC Plasma cuts thick steel plates faster and at a lower cost than laser cutting. For structural fabrication involving plates above 6 mm, plasma is a practical and efficient choice for production cutting.
What industries use CNC Plasma Cutting Services?
Construction, structural fabrication, automotive, agricultural equipment, oil and gas, power generation, and general engineering industries use CNC Plasma Cutting for structural components, machine parts, and custom profiles.
Does CNC Plasma Cutting require skilled operators?
No. The cutting program is loaded from a CAD drawing, and the CNC machine runs the job automatically. The operator monitors the process, but no manual cutting skill is required to produce accurate parts.
