Product Features:
1. Fully Automated Production System
The production line integrates an intelligent material handling system comprising transverse conveyors, rotary loading devices, automatic unloading units, and transfer mechanisms. Drilling and punching operations are completed within one continuous automated cycle, minimizing manual intervention, reducing labor costs, and improving production efficiency, consistency, and operational reliability.
2. High-Precision Drilling Assembly
The drilling unit is equipped with premium BT40 precision spindles manufactured in Taiwan, featuring an internal coolant supply for enhanced drilling performance and machining accuracy. Six CNC-controlled drilling heads are symmetrically arranged, with three units positioned on each side of the angle steel. When processing holes of identical diameter and equal edge distance, the corresponding drilling heads operate simultaneously, significantly increasing machining productivity while maintaining excellent positional precision.
3. Intuitive Human–Machine Interface
The control platform provides a bilingual Chinese-English operating interface with clear graphical visualization of workpiece layouts. The intuitive interface simplifies machine operation, improves programming efficiency, and reduces operator training requirements.
4. Efficient Programming Capability
Programming is streamlined and user-friendly. Operators simply enter essential parameters such as workpiece dimensions, hole diameters, hole spacing, and production quantities. The system also supports direct import of CAD/CAM nesting data and is fully compatible with TEKLA-generated .NC1 files, enabling seamless integration into existing digital manufacturing workflows.
5. Premium Industrial Components
Critical hydraulic, pneumatic, and electrical components are supplied by internationally recognized manufacturers, ensuring outstanding operational reliability, stable machine performance, and extended equipment service life.
6. Intelligent Fault Monitoring
An integrated automatic diagnostic system continuously monitors machine status, quickly detects operating abnormalities, and provides fault identification to simplify troubleshooting and reduce maintenance downtime.
7. Optional High-Efficiency Shearing Unit
An optional dual-blade shearing module is available to provide highly accurate cutting performance. Utilizing advanced shearing technology, it improves processing efficiency while ensuring clean, precise cutting quality.
The demonstration specimens represent standard angle steel profiles and typical hole configurations commonly used in transmission tower fabrication. These samples allow customers, engineers, and quality inspectors to directly evaluate machining precision, hole quality, dimensional consistency, and overall processing performance, providing reliable verification of the production line's capability for practical manufacturing applications.
In Ultra-High-Voltage (UHV) transmission line projects, where transmission towers must withstand severe environmental conditions and substantial structural loads, this production line plays a vital role in manufacturing the angle steel members that form the towers' primary load-bearing framework. It performs high-precision drilling and punching on components used for tower bodies, cross-arms, and other critical structural assemblies, ensuring accurate hole locations, dependable connection quality, and superior assembly precision. By enhancing structural integrity, operational safety, and long-term durability, the equipment provides reliable manufacturing support for modern power transmission infrastructure and large-scale tower fabrication projects.
