Clamping Method

Electrically actuated multi-jaw self-centering concentric clamping ensures uniform circumferential force distribution on the pipe. This design prevents deformation during the processing of thin-walled steel pipes, while also providing a certain degree of rounding correction for thin-walled pipes with excessive ovality.

*Clamping Jaw Layers

Two layers, with one layer mounted on the main unit's telescopic clamping jaws (no disassembly required). For pipe diameter adjustments within the machine's processing range, only one layer needs to be disassembled/installed. A slide-out mechanism enables rapid tooling change, with replacement time ≤5 minutes.

*Minimum Processable Pipe Length

CTA-6, CTA-12, CTA-16, CTA-24: 250mm

CTA-32, CTA-40: 300mm

*Minimum Finished Pipe Length

50mm (though length is theoretically unrestricted in principle).

Base Lifting System

The beveling machine is equipped with an integrated electric lifting base, enabling vertical height adjustment of the machining head. The system comprises:

l Motor reducer

l Four sets of ball screw actuators

l Transmission mechanisms

Base Lifting Method

Synchronized lifting via four ball screw actuators based on the pipe diameter.

Control System

Japanese Mitsubishi PLC CNC program for automatic control, with 10-inch human-machine interface (HMI) for input and display of processing parameters.

 *Specialized Program for Stainless Steel & Alloy Steel Processing

Embedded with proprietary processing programs developed by our company for stainless steel and alloy steel. Utilizes "Stepping Feed" technology, integrating Retract Control during feeding to achieve Chip Breaking & Evacuation, preventing chip entanglement, tool jamming, or blade chipping. Tool Life Enhancement: Over 3 times longer than conventional cutting/beveling machines.

Process Storage & Recall

Allows storage of optimized processing parameters in the system. Enables direct recall of programs for identical pipes in subsequent operations. Supports Preset, Store, Recall of processing programs.

Intelligent Parameter Auto-Search & Matching

Automatically searches and matches suitable processing parameters from the database after selecting material type and inputting pipe diameter/wall thickness, minimizing setup errors and operational risks.

Height Adjustment for Pipe Diameter Variation

Automatically adjusts the tool head’s center height based on preset pipe diameter to ensure alignment with the pipe axis, accommodating height variations across different pipe sizes.

Operational Simplicity

User-friendly design with minimal learning curve. Requires only basic parameter input to initiate processing.
