Product feature
The CNC Angle Drilling and Marking Machine Line is an automated system for high-precision angle steel processing in tower fabrication. It includes transverse/overturn/infeed conveyors, CNC carriage, two drilling units (3 spindles each), one marking unit, unloading conveyor, plus hydraulic, cooling, and pneumatic systems.
Key features include CNC + servo feeding for accuracy and efficiency, stepless spindle/feed speed adjustment, automatic rapid/work movements, precise hole spacing via holistic CNC unit movement, and circulating coolant for longer drill life. Marking is hydraulic-driven with preset positions and imported components.
The process is fully automatic (drilling, marking, pneumatic unloading), controlled by host computer + PLC—just input dimensions for auto program generation (save/select/display). It supports bent angles with pressing devices and includes self-diagnosis for reliability.
