Product Features:
1. Fully Automated Manufacturing Solution
The production line is equipped with an advanced automated material handling system, including transverse conveying units, rotary loading mechanisms, automatic feeding devices, unloading systems, and transfer assemblies. All drilling and marking processes are completed through a continuous integrated machining cycle, significantly reducing manual operations, lowering labor requirements, and enhancing production efficiency, process stability, and overall manufacturing reliability.
2. High-Efficiency Precision Drilling System
The drilling unit adopts high-quality BT40 precision spindle systems manufactured in Taiwan, featuring an internal coolant delivery design to achieve excellent drilling accuracy, superior hole surface quality, and prolonged tool service life. The equipment is configured with six CNC-controlled spindle heads arranged symmetrically, with three drilling units installed on each side of the angle steel section. When machining holes with the same diameter and equal distance from the reference edge, the corresponding spindle units can operate simultaneously, greatly improving processing efficiency while maintaining outstanding positioning accuracy.
3. Advanced Human–Machine Interface (HMI)
The CNC control system features a bilingual Chinese-English operating interface with intuitive graphical displays of workpiece layouts, machining information, and operating status. The user-friendly design simplifies machine operation, improves programming efficiency, and reduces operator training requirements.
4. Intelligent and Efficient Programming System
The programming system is developed for convenient and efficient operation. Operators only need to input basic machining parameters, including workpiece dimensions, hole diameters, hole spacing, and production quantities, after which the system automatically generates the required machining programs. The system also supports direct import of CAD/CAM processing data and full compatibility with TEKLA NC1 files, enabling smooth integration with modern digital engineering and intelligent manufacturing workflows.
5. Reliable Core Components
The machine incorporates high-quality hydraulic, pneumatic, and electrical components supplied by internationally reputable manufacturers. This configuration ensures dependable operation, excellent system stability, reduced maintenance requirements, and extended equipment service life under continuous industrial production environments.
6. Intelligent Monitoring and Diagnostic System
An advanced intelligent monitoring system continuously tracks equipment operating conditions and automatically detects abnormal situations and system faults in real time. This diagnostic function enables rapid fault identification, simplifies maintenance procedures, reduces production interruptions, and improves overall equipment availability.
7. Optional Precision Shearing Module
An optional dual-blade shearing unit is available to further expand the production line’s processing capabilities. Utilizing advanced cutting technology, the module provides high-accuracy shearing performance, improved production efficiency, and smooth, high-quality cut surfaces, making it suitable for demanding structural steel fabrication applications.
The demonstration workpieces include standard angle steel profiles and typical hole configurations commonly applied in transmission tower manufacturing. These representative samples offer customers, engineers, and quality control professionals a practical basis for evaluating machining accuracy, hole quality, dimensional consistency, and overall processing performance, clearly verifying the production line’s ability to meet the strict manufacturing requirements of modern tower fabrication.
In Ultra-High-Voltage (UHV) power transmission projects, transmission towers must withstand severe environmental conditions and substantial structural stresses throughout their service life. This production line plays an essential role in manufacturing the angle steel components that form the primary load-bearing structures of transmission towers. It performs high-precision drilling and punching operations on angle steel members used for tower bodies, cross-arms, and other critical structural assemblies, ensuring accurate hole positioning, reliable connection quality, and excellent assembly precision. By enhancing structural strength, operational safety, and long-term service reliability, the system provides an efficient and dependable manufacturing solution for advanced power transmission infrastructure and large-scale transmission tower production.
