AUTOMATIC CUTTING & BEVELLING

Automatic Cutting & Bevelling Machines are specialized equipment designed for preparing pipe ends, plate edges, or structural components before welding. By combining cutting (making a clean end) and bevelling (creating a pre-weld bevel or chamfer angle) in a single automated or semi-automated process, these machines significantly improve fabrication efficiency, weld quality, and consistency. They are widely used in industries such as shipbuilding, pressure vessels, pipelines, automotive, structural steel, and power generation.

These machines perform operations with minimal manual intervention. Key motions (rotation, clamping, tool feeding, angle adjustment) are often hydraulically or electrically driven, ensuring high precision, repeatability, and throughput. By automating the process, they reduce errors, reduce cycle time, and improve safety, especially when handling thick or high-value materials.

Key Features

Used for pipe continuous cutting and beveling.
It works according non-rotating tools, rotating pipes.
The pipe clamping, locating, tool feeding are all driven by hydraulic. High machining precision can be guaranteed by the steady tool feeding.
The feeding, locating, clamping, beveling, cutting of raw material pipe can be automatically finished in turns with high efficiency.
