Product Features:
1. Superior drilling efficiency and hole-forming precision
The drilling assembly is furnished with six CNC drilling heads,
with three integrated into each flange of the angle steel. Holes
featuring identical diameter and end distance on both flanges can
be concurrently drilled by corresponding bilateral drilling heads.
The drilling spindle incorporates a Taiwanese BT40 precision
spindle (with internal cooling), while the drilling head utilizes a
cemented carbide drill bit. This configuration enables a cutting
speed of up to 200m/min—markedly higher than the 25-35m/min
typically achieved by standard high-speed steel twist drills—thus
ensuring rapid operation.
The CNC drilling power head is driven by a servo motor, with its
rapid advance, working feed, and rapid retraction controlled and
automated by the CNC system. The retraction position of the drill
bit can be pre-set via the host computer, reducing idle travel and
further enhancing production efficiency.
Holes produced boast a diameter tolerance of less than 0.1mm and a
surface finish (Ra) of less than 6.3μm, underscoring exceptional
hole processing quality.
2. The drilling spindle is integrated with a disc spring automatic
tool-drawing mechanism and a hydraulic cylinder for tool release,
facilitating highly convenient replacement of tool shanks. The
front section of the spindle features a labyrinth-style protection
system, a waterproof design, and is equipped with an air curtain
device—all of which collectively prevent cutting fluid from
infiltrating the interior of the spindle.
These specimens encompass a range of common specifications and hole
patterns of angle steel employed in transmission line towers. They
enable potential users or inspectors to visually validate the
equipment’s performance, thereby offering a tangible and intuitive
reference for evaluating its fitness for practical production
requirements.
It is primarily designed for drilling and stamping large-size,
high-strength angle steel utilized in transmission line towers, and
finds extensive application in various scenarios within the
construction and maintenance of power transmission infrastructure.
In the construction of ultra-high voltage (UHV) transmission lines,
where towers need to withstand extreme weather conditions and heavy
loads, this equipment plays a crucial role in processing the angle
steel components that form the main framework of the towers. It
efficiently handles the drilling and stamping tasks for the angle
steel used in the tower bodies, cross-arms, and other key
structural parts, ensuring precise dimensions and strong
connections to guarantee the overall stability of the towers.
