Product Features:
1. Fully Automated Manufacturing System
The production line incorporates an advanced automated material handling system consisting of transverse conveying units, rotary loading mechanisms, automatic discharge devices, and material transfer assemblies. All drilling and punching operations are completed within a single uninterrupted production cycle, significantly reducing manual involvement, lowering labor costs, and enhancing manufacturing efficiency, process consistency, and operational stability.
2. High-Precision Drilling System
The drilling module is equipped with high-quality BT40 precision spindles manufactured in Taiwan, featuring an internal coolant delivery system to ensure superior drilling performance, excellent hole quality, and outstanding dimensional accuracy. The machine is configured with six CNC-controlled drilling heads arranged symmetrically, with three units installed on each side of the angle steel profile. When machining holes with identical diameters and equal distances from the reference edge, paired drilling heads can operate simultaneously, substantially improving production throughput while maintaining exceptional positional accuracy.
3. User-Friendly Human–Machine Interface
The CNC control system features a bilingual Chinese-English operating interface with intuitive graphical display of workpiece layouts and machining information. The user-friendly interface simplifies operation, accelerates programming procedures, and minimizes operator training requirements.
4. Simplified Programming System
The programming process is designed for maximum efficiency and ease of use. Operators only need to input basic machining parameters, including workpiece dimensions, hole diameters, hole spacing, and production quantity. The system also supports direct import of CAD/CAM nesting data and is fully compatible with TEKLA-generated NC1 files, allowing seamless integration into modern digital manufacturing environments.
5. High-Quality Core Components
Major hydraulic, pneumatic, and electrical components are selected from internationally recognized suppliers, ensuring dependable machine performance, excellent operational stability, and extended service life under demanding industrial production conditions.
6. Intelligent Diagnostic System
An advanced self-monitoring and fault diagnosis system continuously supervises machine operation, automatically detecting abnormalities and identifying faults in real time. This intelligent function facilitates rapid troubleshooting, reduces maintenance time, and maximizes equipment availability.
7. Optional Precision Shearing Module
An optional dual-blade shearing unit is available to further expand processing capability. Utilizing advanced shearing technology, the module delivers high-accuracy cutting, improved productivity, and clean, high-quality cut surfaces suitable for demanding 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.
