1000/1200KN Marking Force CNC Angle Drilling And Marking Machine
Model JNC2532/ADM2532/ADM3635
Product Usage:
The CNC angle drilling and marking machine line is primarily used
for drilling and stamping large, high-strength angle steel in
transmission line towers. All holes in angle steel can be drilled
on this line, achieving high hole quality and positional accuracy,
while also offering high production efficiency and a high degree of
automation.

Product Features:
1. High degree of automation. The production line is equipped with
automatic loading device (horizontal feeding channel and rotating
loading rack), automatic unloading device and automatic feeding
device. All holes and steel stamps on the angle steel can be
processed in one go through the production line. The processing
process does not require manual assistance, which can greatly
reduce the labor intensity of workers.
2. The drilling spindle adopts Taiwan BT40 precision spindle
(internal coolant), ensuring high drilling efficiency and accuracy.
The drilling unit is equipped with six CNC drilling heads, three on
each wing of the angle steel. Holes of the same diameter and at the
same distance from the upper ends of the angle steel wings can be
drilled simultaneously by the corresponding drilling heads on both
sides.
3. Software with Chinese/English interface, easy operation, and can
display the drawing of workpiece.
4. Easy programming, just need to input size of workpiece, diameter
of holes, stadia and quantity of workpiece when edit program, or
use CAD/CAM lofting software direct conversion. lt can read .NC1
files generated by TEKLA software.
5. Key hydraulic, pneumatic and electric parts all famous brands.
6. With self-diagnosis failures function.
7. Shearing unit is optional, using double blades cutting.
These specimens cover a range of common specifications and hole
configurations of angle steel employed in the construction of
transmission line towers. They allow prospective users or
inspectors to visually verify the operational performance of the
equipment, thereby providing concrete and intuitive references for
evaluating whether the equipment meets the practical production
demands of transmission line tower manufacturing.
In the construction of ultra-high voltage (UHV) transmission
lines—where transmission towers must endure extreme weather
conditions and heavy loads—this equipment plays a pivotal role in
processing angle steel components for the towers’ main load-bearing
frameworks. It efficiently carries out drilling and stamping
operations on angle steel used in tower bodies, cross-arms, and
other key structural components, guaranteeing high dimensional
accuracy and reliable connection performance. This, in turn,
protects the overall structural stability of the transmission
towers during their entire service life.
