18 Character CNC Angle steel tower Drill And Tap Machine 33*8.5*2.5m Overall Dimension

Product Usage:

This production line is custom-engineered specifically for the drilling and stamping processing of large-dimensional, high-strength angle steel utilized in transmission line towers. All mandatory holes required on the angle steel can be machined on this production line, which delivers premium hole quality, high positional accuracy, along with exceptional production efficiency and advanced automated capabilities.

Main parameters:

Product Features:

1. Exceptional Automation Level. The production line is outfitted with an automatic loading system (comprising a transverse feeding channel and a rotating loading frame), an automatic unloading system, and an automatic material feeding system. All hole-drilling operations and steel mark engraving processes for angle steel can be completed in a single pass through the production line, with no manual intervention required. This significantly alleviates the labor intensity for operators.

2. Cost-Effective Drilling Solutions with Advanced Cooling. It is recommended to use cemented carbide drills with replaceable inserts, which are fitted with four interchangeable cutting blades and require no sharpening—substantially reducing production costs. The drilling process employs the most advanced Minimal Quantity Lubrication (MQL) cooling system. This system mixes compressed air with an ultra-small volume of lubricant (cutting oil), vaporizes the mixture, and sprays it into the machining area to achieve efficient cooling and lubrication.

3. User-Friendly Tool Replacement for Drilling Spindles. The drilling spindle is equipped with a disc spring automatic tool-clamping mechanism and a hydraulic cylinder for tool release, facilitating highly convenient tool shank replacement. The front section of the spindle incorporates a labyrinth seal for protection, a waterproof design, and an air curtain device. These features effectively prevent cutting fluid from infiltrating the interior of the spindle.

4. Robust and Stable Typing Unit with Enclosed Structure. The printing unit features a machine base-mounted bed support, a movable bed, and a hydraulic-driven press head character box. It executes printing at the positions specified in the engineering drawings in accordance with computer-generated instructions. To expand the machine’s processing scope, a manual adjustment mechanism has been integrated, enabling adjustments to the downward position of the movable body (i.e., the character head position).

These specimens cover a spectrum of common specifications and hole patterns of angle steel applied in transmission line towers. They allow potential users or inspectors to visually verify the operational performance of the equipment, thereby providing concrete and intuitive references for assessing whether the equipment meets practical production requirements.

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 serves a critical function in processing the angle steel components that constitute the main framework of the towers. It efficiently fulfills the drilling and stamping tasks for angle steel used in tower bodies, cross-arms, and other key structural components, ensuring precise dimensional accuracy and robust connections to safeguard the overall stability of the towers.
