Dish Head Dome Plasma Pressure Vessel Bevel Cutting Machine
Plasma bevel dish head cutting machine is a CNC plasma cutting equipment specially used for processing end heads and completing bevels at the same time. It is mainly used in petrochemical industry, pressure vessels, boilers, pipelines and other industries. It is used to cut round, oval, disc and other seals, and accurately process the bevel angle required for welding to ensure the quality of subsequent welding.
1. Highly efficient and precise head processing capability
It is specifically designed for dish heads: it can cut complex curved end caps such as Ellipsoidal, Torispherical, Hemispherical, Conical, Toriconical, etc., meeting the needs of the petrochemical and pressure vessel industries.
2. Integrated beveling function to improve welding quality
Intelligent bevel cutting and One-time cutting forming: supports various bevel angles such as V-type, X-type, K-type (e.g., 30°, 45°, 60°), meeting different welding process requirements.
3. Automation and intelligent operation
CNC programming: supports CAD/CAM drawing import, automatically generating cutting paths, reducing manual intervention.
Automatic height adjustment system: real-time adjustment of cutting torch height, adapts to curved surface cutting, avoiding collisions or arc breaks.
4. Strong adaptability, covering various materials and thicknesses
Wide range of materials: can cut metals such as carbon steel, stainless steel, alloy steel, aluminum, etc., suitable for different industrial scenarios.
Efficient cutting of medium and thick plates: Plasma power covers 100A~400A, can process thicknesses of 5~100mm (depending on power), and speeds are 3~5 times faster than flame cutting.
What is a head?
Head is a curved structural member used to close off the end of a pipe, vessel or equipment, usually in the shape of a circle, oval, disk, cone or hemisphere. It is an important part of pressure vessels, tanks, piping systems and other equipments, playing the roles of sealing, pressure bearing and structural support.
