Product Introduction:

The production line is suitable for power towers, communication, steel structure bar marking, and drilling.

Product configuration:

Product Structure Characteristics:

1. The equipment incorporates a highly automated production system engineered to optimize the entire manufacturing workflow. The production line combines automatic loading mechanisms, including horizontal feeding channels and rotary support racks, with automatic unloading and material replenishment systems. All angle steel hole-processing and marking procedures are integrated into a continuous and fully automated production cycle, substantially reducing the requirement for manual operation. This configuration lowers operator workload while enhancing production efficiency, process continuity, and overall manufacturing consistency.

2. The marking unit adopts a fully enclosed, high-rigidity structural configuration, providing superior mechanical stability and reliable operational performance. The assembly comprises a fixed support frame, movable carriage, hydraulically actuated marking head, and other essential components. Under the control of predefined CNC programs, the system performs precise and repeatable marking operations based on designated machining coordinates. A manual adjustment mechanism is incorporated to improve operational adaptability, enabling accurate vertical adjustment of the movable assembly and marking head to accommodate angle steel profiles with different dimensions and specifications.

3. The equipment delivers high positioning accuracy throughout the entire hole-machining operation. The feeding mechanism is servo-actuated through rack-and-pinion transmission assemblies and incorporates detection gears and rotary encoders for continuous position feedback, thereby establishing a comprehensive closed-loop positioning system. At the same time, the drilling spindle heads positioned on both sides of the angle steel are servo-driven through precision ball screw transmission mechanisms. This arrangement ensures accurate hole positioning and stable, consistent machining quality for angle steel components.

4. The machine is designed for high drilling productivity and superior machining performance. The drilling system consists of six independent CNC drilling power units, with three spindle assemblies symmetrically configured on each side of the angle steel profile. When processing holes of identical diameter and equal spacing on both angle steel flanges, the corresponding spindle units on the two sides can operate synchronously and complete drilling simultaneously. This coordinated machining method substantially improves drilling productivity and reduces the overall processing cycle time.

5. The drilling spindle utilizes a Taiwan-manufactured BT40 high-precision spindle with an integrated internal coolant passage and is configured with solid carbide drilling tools. The maximum cutting speed can reach 200 m/min, substantially higher than the typical 25–35 m/min cutting speed of conventional high-speed steel twist drills, while also supporting increased feed rates. Each CNC drilling unit is equipped with a servo motor for feed-axis control, with rapid positioning, cutting feed, and tool retraction precisely coordinated by the CNC control system. The operator can preset the tool-retraction position through the industrial computer, effectively reducing non-cutting travel and further increasing production efficiency. Finished-hole accuracy is controlled within 0.1 mm, while surface roughness is maintained below Ra 6.3 μm, delivering high-quality machining results and excellent dimensional consistency.

6. Indexable carbide insert drills are recommended for production applications. Each cutting tool incorporates four replaceable carbide inserts, eliminating the need for manual regrinding and helping reduce tooling and operating costs while simplifying tool maintenance and management. The drilling system is equipped with an advanced Minimum Quantity Lubrication (MQL) system, which combines compressed dry air with a precisely metered quantity of cutting fluid to generate a fine atomized mist and deliver it directly to the cutting zone for effective cooling and lubrication. Cutting-fluid consumption is exceptionally low, at approximately 5 ml to 50 ml per operating hour.

7. The optimized lubrication and cooling configuration provides effective thermal management while minimizing coolant leakage beyond the machining area. This arrangement helps maintain a clean and well-organized workshop environment and eliminates the need for additional coolant collection, filtration, and disposal procedures. Consequently, workshop cleaning and maintenance are simplified, while overall operational requirements and associated costs are reduced.

8. Roller-type linear guideways are employed to guide and support the drilling power heads during their movement. With high structural rigidity, excellent static and dynamic load-bearing capacity, and smooth motion characteristics, these guideways improve machining stability and positioning accuracy while contributing to enhanced component precision and extended cutting-tool service life.

9. The primary electromagnetic control valves incorporated into the hydraulic system are sourced from reputable international manufacturers, while the hydraulic pipelines utilize reliable ferrule-type compression fittings. The hydraulic power unit is equipped with forced-air cooling to effectively control the operating oil temperature, maintaining stable hydraulic performance and ensuring reliable operation during extended periods of continuous production.

10. The main control system features an intuitive, operator-oriented Human–Machine Interface (HMI). The interface provides graphical visualization of workpiece coordinates, dimensional parameters, and hole-position information, enabling convenient data verification and efficient machining-process management. The system supports direct import of machining programs generated by nesting optimization software, while centralized upper-computer management improves the efficiency of CNC program storage, classification, administration, and historical data retrieval.

These test samples encompass a complete spectrum of standard specifications and diversified hole arrangement designs for angle steel exclusively utilized in power transmission tower manufacturing. They enable prospective clients and professional inspection personnel to conduct intuitive verification of the equipment’s practical operational performance, and provide credible, practical evaluation criteria to validate whether the equipment fully complies with the actual production standards and application requirements of power transmission tower fabrication.

These trial processing specimens cover full standard dimensional series and customized hole distribution configurations of special tower angle steel for power transmission engineering. They allow potential buyers and quality inspection staff to perform visual evaluation of the equipment’s real-world processing capability, and serve as intuitive and authoritative verification benchmarks to confirm the equipment’s adaptability and compliance with on-site manufacturing specifications for transmission tower production.
