NODHA CNC Pipe Beveling Machine Customized Solution

NODHA's latest CNC pipe beveling machine, with its unique four-jaw chuck clamping technology and blade rotation machining method, provides an ideal solution for pipe beveling that balances precision, efficiency, and flexibility.

I. Customer Background

Our clients serve the chemical, shipbuilding, and energy equipment industries. The pipe processing tasks they undertake exhibit three main characteristics:

Large Specification Range: From small pipes for instrumentation systems to main process pipelines, pipe diameters range from Φ50mm to over Φ400mm, and wall thicknesses vary from thin-walled (3-4mm) to thick-walled (30-50mm).

Various Pipe Lengths: Both standard length pipes (6-12 meters) and a large number of non-standard length loose pipes need to be processed.

High Quality Requirements: Beveling angles, blunt edge accuracy, and end face flatness must meet the stringent requirements of automatic welding equipment for interface consistency.

Previously, this machining center used multiple types of beveling equipment simultaneously: manual or semi-automatic equipment for short pipes, and large floor-standing machine tools for long pipes. This parallel operation of multiple machines led to frequent tooling changes, large footprint, and high skill requirements for operators, severely impacting overall output efficiency.

II. NODHA Solution: CNC Beveling Machine

To address these challenges, NODHA offers its latest CNC pipe beveling machine, which precisely responds to user needs with three core design features:

1. Four-jaw chuck clamping for high-precision centering: The machine comes standard with a high-precision four-jaw self-centering chuck, which is crucial for ensuring machining quality. Compared to traditional three-jaw chucks, the four-jaw structure provides more even force distribution and higher centering accuracy when clamping large-diameter, thick-walled pipes, effectively avoiding ellipticity deviations caused by clamping deformation.

2. Rotating cutter head for stable handling of any length: This machine adopts a machining principle of "stationary pipe, rotating cutter head." The pipe is firmly secured by a four-jaw chuck, while a cutter head equipped with carbide blades rotates at high speed around the pipe end for cutting. This structure completely solves the problems of large space requirements for long pipes and the impact of centrifugal force on machining accuracy associated with rotary pipe cutting equipment. Whether the pipe length is 1 meter or 12 meters, as long as the front end is clamped and fixed, the rear end can extend freely, truly achieving "processing of any length."

3. Wide-range processing capability, one machine covers the entire production line

This equipment is designed to process pipe diameters from Φ50mm to Φ426mm, and wall thicknesses from 3mm to 50mm. This means that from small-diameter stainless steel instrument pipes of Φ50mm to large-diameter oil pipes of Φ406mm, from thin-walled air ducts of 3mm to ultra-thick-walled pressure pipelines of 50mm, users can easily switch between different types of pipes without changing the main unit, simply by adjusting the chuck position and cutting parameters.

III. Implementation Results and Customer Feedback

Significantly improved processing efficiency and overall efficiency.

Enhanced quality stability: The CNC system ensures high consistency of parameters for each bevel, providing a reliable guarantee for subsequent automated welding and significantly improving the first-pass yield.

Outstanding ease of operation: The touchscreen interface, coupled with a pre-set process database, allows ordinary operators to quickly learn and operate the equipment after simple training, reducing reliance on highly skilled welders.
