2000～13000mm Beam Length High Speed CNC H Beam Drilling Machine
10#～40# Channel Steel
Machine tool use:
This machine tool is primarily designed for drilling, tapping, and
marking operations on H-shaped steel, channel steel, and other
types of steel. It employs three BT40 high-speed spindles to
perform drilling on three faces of the steel, with one spindle
allocated to each face. The corresponding row-type tool magazine
can hold up to 4 specifications of drill bits.
It features high processing efficiency, high precision, ease of
operation, and broad applicability. As such, it is widely utilized
in steel structure industries including construction, garages,
towers, and grids.

Machine Tool Structure and Configuration:
This machine tool is primarily composed of a drilling unit, feeding
trolley, feeding channel, discharging channel, cooling system,
hydraulic system, pneumatic system, lubrication system, and
electrical system, among other components. The machine tool adopts
a structure featuring a fixed bed and a movable workpiece. This
three-dimensional drilling structure facilitates automated
production.
1. Drilling Machine
The drilling machine is primarily composed of a base, bed, movable
slide, spindle box, upper pressing device, side clamping device,
and row tool magazine.
The machine tool is equipped with three spindle boxes: the
fixed-side spindle box, movable-side spindle box, and upper-unit
spindle box, which are respectively used for drilling operations in
horizontal and vertical directions. Each spindle box can operate
independently and perform drilling simultaneously, significantly
enhancing production efficiency. Each spindle box is fitted with a
set of BT40 high-speed mechanical spindles, and the corresponding
row tool magazine can accommodate a maximum of 4 drill bits with
different diameters (when no tool is mounted on the spindle). This
allows for automatic processing of 4 different hole diameters in a
single workpiece clamping.
2. Feeding Trolley
The feeding trolley is composed of gears, servo motors, and
manipulators. The manipulator clamps the workpiece and is driven by
a servo motor. Through the transmission of the gear rack, the
workpiece is fed in the X direction, ensuring the longitudinal
machining accuracy of the drilling operation.
3. Feeding Channel
The feeding channel is composed of a channel bracket, support
rollers, side positioning rollers, side pushing mechanisms, racks,
and other components. It is designed to carry workpieces awaiting
processing. A photoelectric switch is mounted at the front end of
the channel to detect the workpiece's leading edge, thereby
determining the X-direction processing reference. The side
positioning rollers conduct rough positioning of the workpiece in
the Y direction, while the side pushing mechanisms press the
workpiece against the side positioning rollers to secure its
position.
This machine tool is primarily designed for performing drilling,
tapping, and marking operations on H-shaped steel, channel steel,
and various other types of steel. It is capable of handling a wide
range of steel workpieces with different specifications, ensuring
precise and efficient processing. For instance, in sample displays,
it can effectively demonstrate its processing capabilities on
standard H-shaped steel samples with varying flange widths and web
thicknesses, as well as channel steel samples of different sizes.
These displayed samples clearly showcase the machine tool’s ability
to achieve accurate hole positions, smooth tapped threads, and
clear marking patterns, fully reflecting its high precision and
reliability in practical applications. Such sample demonstrations
provide evidence for customers to understand the machine tool’s
performance and suitability for their specific processing needs.
High Speed CNC H Beam Drilling Machine finds key applications in
steel structure workshops and bridge construction.
In steel structure workshops, it precisely processes H-beams for
frames and supports, ensuring stable assembly. For bridges, it
handles H-beam drilling with high accuracy, enhancing structural
integrity to withstand long-term loads. Its efficiency supports
these critical infrastructure sectors reliably.
