Product Features:
1. The CNC angle steel drilling production line is integrated with a fully automated material handling system, including a horizontal feeding conveyor, rotary loading table, automatic feeding unit, and automatic discharge mechanism. All drilling and marking processes are completed within one uninterrupted production cycle without manual operation. This advanced automation significantly reduces labor intensity, enhances production efficiency, and ensures stable and consistent machining performance.
2. The drilling system is equipped with Taiwan-manufactured BT40 high-precision spindles featuring an internal coolant supply, delivering exceptional drilling accuracy, superior machining quality, and prolonged tool life. Six CNC-controlled drilling heads are symmetrically arranged, with three units installed on each side of the angle steel section. When machining holes of identical diameter and equal edge distance, the corresponding drilling heads operate simultaneously, substantially increasing machining efficiency and productivity.
3. The CNC control system provides bilingual Chinese-English operation and incorporates an intuitive Human–Machine Interface (HMI). Engineering drawings can be displayed directly on the control screen, allowing convenient operation, efficient production supervision, and straightforward program validation.
4. The programming process is designed for simplicity and flexibility. Operators only need to enter essential parameters such as workpiece dimensions, hole diameters, hole spacing, and production quantity, after which the system automatically generates the machining program. It also supports direct import of data from CAD/CAM software and offers full compatibility with TEKLA-generated NC1 files, enabling seamless integration with engineering design and digital manufacturing systems.
5. All key hydraulic, pneumatic, and electrical components are sourced from internationally renowned manufacturers, ensuring reliable machine performance, excellent operational stability, and extended equipment service life.
6. An intelligent fault diagnosis system continuously monitors machine operation, automatically detecting abnormalities and identifying faults in real time. This function simplifies maintenance procedures, shortens troubleshooting time, and minimizes production interruptions.
7. An optional shearing unit is available to enhance the machine's processing versatility. Utilizing advanced dual-blade shearing technology, the cutting module delivers high cutting precision, excellent edge quality, and improved production efficiency.
The demonstration workpieces consist of a range of standard angle steel profiles and representative hole patterns commonly applied in transmission tower fabrication. These samples allow customers, engineers, and quality inspectors to directly assess machining accuracy, hole quality, dimensional consistency, and overall processing capability, providing a dependable reference for evaluating the equipment's performance in practical transmission tower manufacturing applications.
In Ultra-High-Voltage (UHV) power transmission projects, where transmission towers must withstand severe environmental conditions and substantial structural loads, this equipment plays an essential role in machining the angle steel members that constitute the primary load-bearing framework of the towers. It performs high-precision drilling and marking operations on angle steel components used in tower bodies, cross-arms, and other critical structural assemblies, ensuring accurate hole locations and reliable connection quality. As a result, the machine significantly enhances the structural integrity, operational safety, and long-term service performance of transmission towers throughout their entire operational lifespan.
