CNC Flame Cutting is a technology that uses the high temperature of a gas flame to heat and melt metal plates, achieving the purpose of cutting. By combining traditional flame cutting methods with modern Computer Numerical Control (CNC) systems, this technology significantly improves cutting precision and efficiency.
Development Background
Flame cutting dates back to the early 20th century, when oxygen-acetylene flames were first used for metal cutting. With technological advancements—especially in computer technology and automation—flame cutting gradually evolved toward numerical control. By mounting a flame cutting torch on a programmable robotic arm or moving platform, guided by a computer control system along a pre-programmed path, CNC flame cutting enables efficient and precise processing of complex workpiece shapes.
Technical Principle
CNC flame cutting relies on the high-temperature flame produced by burning fuel gases (such as acetylene or propane) mixed with oxygen to heat the metal to its ignition point. A high-pressure oxygen stream then blows away the molten metal, creating a cut. This process is suitable for various metals, especially iron-based alloys like carbon steel, and is widely adopted due to its low cost and suitability for large-scale production.
Features and Advantages
- Cost-effective: For medium-to-thick plates, especially carbon steel, CNC flame cutting offers a highly economical solution.
- Wide applicability: Capable of cutting plates ranging from a few millimeters to hundreds of millimeters in thickness, meeting diverse industrial needs.
- High flexibility: Supported by CNC systems, cutting paths can be easily adjusted to accommodate complex and varied design requirements.
- Simple maintenance: Compared to laser or plasma cutting, flame cutting equipment has a relatively simple structure, making it easier to maintain and service.
