Product Features:

1. Fully Automated Production System
The production line integrates an intelligent material handling system comprising transverse conveyors, rotary loading units, automatic feeding mechanisms, unloading devices, and transfer assemblies. Drilling and marking operations are completed within a single continuous machining cycle, minimizing manual intervention, reducing labor costs, and improving production efficiency, operational consistency, and overall manufacturing reliability.

2. High-Performance Drilling Unit
The drilling system is equipped with premium BT40 precision spindles manufactured in Taiwan, featuring an internal coolant supply to ensure excellent drilling accuracy, superior hole quality, and extended tool life. Six CNC-controlled spindle heads are symmetrically arranged, with three drilling units positioned on each side of the angle steel profile. When processing holes of identical diameter and equal edge distance, paired spindle heads can drill simultaneously, significantly increasing machining efficiency while maintaining exceptional positional precision.

3. Intuitive Human–Machine Interface
The CNC control platform provides a bilingual Chinese–English operating interface with clear graphical visualization of workpiece layouts and machining data. Its intuitive design simplifies operation, improves programming efficiency, and shortens operator training time.

4. Efficient Programming Function
The programming system is designed for simple and rapid operation. Users only need to enter essential machining parameters, including workpiece dimensions, hole diameters, hole spacing, and production quantity, to automatically generate machining programs. The system also supports direct import of CAD/CAM-generated data and is fully compatible with TEKLA NC1 files, enabling seamless integration with digital engineering and manufacturing systems.

5. Premium-Quality Key Components
Critical hydraulic, pneumatic, and electrical components are sourced from internationally recognized manufacturers, ensuring reliable machine performance, outstanding operational stability, and an extended service life under continuous industrial production conditions.

6. Intelligent Monitoring and Fault Diagnosis
An integrated intelligent monitoring system continuously supervises machine operation and automatically identifies abnormal operating conditions and system faults in real time. This advanced diagnostic capability enables rapid troubleshooting, minimizes maintenance downtime, and maximizes equipment utilization.

7. Optional High-Precision Shearing Unit
An optional dual-blade shearing module is available to further enhance the production line's processing capabilities. Incorporating advanced shearing technology, the unit delivers precise cutting accuracy, improved production efficiency, and clean, high-quality cut surfaces suitable for demanding structural steel fabrication applications.

The demonstration specimens consist of standard angle steel profiles and representative hole patterns widely used in transmission tower manufacturing. These sample workpieces provide customers, engineers, and quality inspection personnel with a practical reference for evaluating machining precision, hole quality, dimensional consistency, and overall processing performance, clearly demonstrating the production line's capability to satisfy the rigorous requirements of industrial tower fabrication.

In Ultra-High-Voltage (UHV) power transmission projects, where transmission towers are required to withstand harsh environmental conditions and significant structural loads, this production line performs a critical role in manufacturing the angle steel members that constitute the towers' primary load-bearing framework. The equipment carries out high-precision drilling and punching operations on angle steel used for tower bodies, cross-arms, and other essential structural components, ensuring precise hole positioning, reliable joint accuracy, and excellent assembly quality. By improving structural strength, operational safety, and long-term service reliability, the system provides an efficient and dependable manufacturing solution for modern power transmission infrastructure and large-scale transmission tower production.
