4. How Does Plasma Or Flame Cutting Work?

CNC plasma cutting uses high-temperature plasma arcs to melt and remove metal. Here's the step-by-step process:

Plasma Arc Generation: A high-voltage electric arc ionizes a gas (e.g., compressed air, nitrogen) passing through a nozzle, creating a superheated plasma jet (17,700–21,000°C).
Material Melting: The plasma jet melts the metal sheet at the cutting point.
Ejection of Molten Metal: High-velocity plasma flow blows away the molten metal, forming a precise, narrow cut.

CNC flame cutting (oxy-fuel cutting) relies on combustion of ferrous metals with oxygen. Here's its mechanism:

Preheating: A fuel gas (e.g., acetylene, propane) mixes with oxygen to create a preheating flame, raising the metal temperature to ~1,800°C.
Oxidation Reaction: A high-pressure oxygen stream is directed at the preheated area, causing rapid oxidation of iron into molten slag.
Slag Removal: The oxygen jet blows away the slag, cutting through the metal.

9. FAQ

1. What materials can this machine cut?
It can cut carbon steel, stainless steel, aluminum, copper, and other conductive metals. Flame cutting is only suitable for carbon steel and ferrous materials.

2. What is the maximum cutting thickness?
Flame cutting up to 200mm; plasma cutting typically 0.5–50mm depending on the power source.

3. How do I choose between plasma and flame cutting?
Use plasma for thin materials and high precision; use flame for thick carbon steel and cost-sensitive projects.

4. Can the machine be customized?
Yes, OEM/ODM customization is available, including size, configuration, and functions.

5. How is cutting accuracy ensured?
High-precision guide rails, dual-drive system, and strict quality inspection ensure long-term accuracy.

6. Can the machine run continuously?
Yes, it supports 24/7 continuous operation for industrial production.

7. What is the delivery time?
7–15 days for standard machines and 15–30 days for customized models.

8. Is the machine easy to operate?
Yes, it features a user-friendly interface and comes with remote training and guidance.

9. What are the operating costs?
Low operating cost with easy-to-replace consumables. Plasma is efficient, while flame cutting is more economical for thick plates.
