180mm Max Thickness CNC Gantry Plate Flange Drilling Machine
M3-M24mm Tapping Diameter
Application:
This equipment is specifically engineered to perform drilling,
chamfering, tapping, and milling operations on plate-type
components and structural parts. It is primarily deployed for the
high-efficiency drilling of workpieces such as flanges, discs,
rings, and plates—provided that the thickness of these workpieces
falls within the effective processing range. The device enables the
drilling of both through holes and blind holes in single-material
components as well as composite materials. The machining process of
this machine tool is controlled by digital technology, which
guarantees a high degree of operational convenience. It is capable
of meeting the requirements of automated production, high-precision
machining, multi-variety manufacturing, and mass production.

Machine Structure
This machine is primarily composed of core components, including a
bed workbench, a movable gantry, a movable sliding saddle, a
drilling and milling power head, an automatic lubrication unit, a
protective mechanism, a circulating cooling system, a numerical
control system, and an electrical system, among others. It adopts a
rolling guide pair for support and guidance functions, and is
driven by a precision lead screw pair. As a result, this machine
tool demonstrates high positioning accuracy and excellent repeat
positioning accuracy.
Product Features
1. Automatic Lubrication Device and Protective Device
This machine tool is fitted with an original volumetric
partial-pressure automatic lubrication device sourced from Taiwan.
This device delivers automatic lubrication to all kinematic
pairs—including guide rails, lead screws, and racks—without leaving
any unlubricated dead zones, effectively extending the service life
of the machine tool. The X-axis and Y-axis of the machine tool are
equipped with dust-proof protective covers, while waterproof splash
guards are installed around the workbench to enhance operational
protection.
2. Automatic Chip Conveyor and Circulating Cooling Device
An automatic chip conveyor is integrated at the rear of the
workbench, with a filter unit installed at its terminal end. The
automatic chip conveyor adopts a flat-chain design. A cooling pump
is mounted on one side of the machine, and its outlet is connected
to the central water filtration system via a flexible hose. The
coolant flows into the chip conveyor first; subsequently, the chip
conveyor’s lift pump transfers the coolant to the central outlet
filtration system. After filtration, the high-pressure cooling pump
circulates the coolant to provide cutting cooling. Additionally, a
scrap-transporting trolley is equipped to facilitate the convenient
handling and removal of iron scraps.
3. Laser Interferometer
Every unit of this equipment is subjected to calibration using an
API laser interferometer (sourced from the United States). This
calibration process enables accurate inspection and compensation of
key performance indicators, including pitch error, backlash,
positioning accuracy, and repeat positioning accuracy. Such
rigorous calibration ensures the machine’s dynamic and static
stability, as well as its machining precision.
The CNC gantry drilling and milling machine is a high-performance
industrial asset purpose-engineered for the precision machining of
plate-type components and structural parts. This equipment is
tailored for processing workpieces such as flanges, discs, rings,
and plates—with the critical prerequisite that the thickness of
these workpieces strictly complies with the machine’s specified
effective machining range.
Within steel structure workshops, it delivers precise drilling and
milling operations for structural plates and connectors, laying a
solid foundation for the robust assembly of steel frames. For wind
power applications, it performs high-precision processing on wind
turbine towers and flanges—a critical requirement to ensure these
components can withstand harsh operating conditions (e.g., strong
winds, temperature fluctuations). In bridge construction, it
undertakes the machining of girders and brackets, guaranteeing
stable and durable connections capable of withstanding dynamic
loads throughout the bridge’s long-term service life.
