100×100×10~360×360×35mm Angle Size CNC Drilling Line 200m/Min Max. Cutting Speed Of Drill
Product Usage:
The CNC angle steel drilling and marking machine line is primarily designed for drilling and stamping large-sized, high-strength angle steel applied in transmission line towers. All holes required on the angle steel can be processed on this production line, which delivers superior hole quality and positional precision. Meanwhile, it also provides high production efficiency and a high level of automation.

Product Features:
1. High Level of Automation. The production line is outfitted with an automatic loading system (comprising a horizontal feeding channel and a rotating loading rack), an automatic unloading system, and an automatic feeding system. All holes and steel stamps on the angle steel can be completed in a single pass through the production line. No manual intervention is required during the processing procedure, which significantly reduces the labor intensity for workers.
2. The drilling spindle adopts a Taiwan-sourced BT40 precision spindle (with internal coolant supply), which ensures high drilling efficiency and precision. The drilling unit is configured with six CNC drilling heads, with three arranged on each wing of the angle steel. For holes featuring the same diameter and identical distance from the upper ends of the angle steel wings, simultaneous drilling can be achieved via the corresponding drilling heads on both sides.
3. The software features a Chinese/English interface, ensuring user-friendly operation and enabling the display of workpiece drawings.
4. Programming is simplified: when editing a program, users only need to input the workpiece dimensions, hole diameter, hole spacing, and workpiece quantity. Alternatively, direct conversion can be realized using CAD/CAM lofting software. The system is also capable of reading .NC1 files generated by TEKLA software.
5. Key hydraulic, pneumatic, and electrical components all adopt well-known brand products.
6. The equipment is equipped with a fault self-diagnosis function.
7. A shearing unit is available as an optional accessory, which adopts double-blade cutting technology.
These specimens cover a variety of common specifications and hole layouts of angle steel used in the construction of transmission line towers. They enable potential users or inspectors to visually verify the equipment’s operational performance, thereby providing tangible and intuitive references for assessing whether the equipment meets the practical production requirements of transmission line tower manufacturing.
In the construction of ultra-high voltage (UHV) transmission lines—where transmission towers are required to withstand extreme weather conditions and heavy loads—this equipment assumes a crucial role in processing angle steel components for the towers’ main load-bearing frameworks. It efficiently performs drilling and stamping operations on angle steel used in tower bodies, cross-arms, and other key structural components, ensuring high dimensional accuracy and reliable connection performance. This, in turn, safeguards the overall structural stability of the transmission towers throughout their entire service life.
