1.Introduction for H beam 3D drilling machine:

This machine tool is primarily designed for drilling operations on H‑beams, channel steel, and box‑type beams, and is widely used in industries such as steel structure construction, bridge building, and parking garage fabrication.

The 7‑axis CNC steel three‑dimensional drilling machine utilizes seven servo motors to achieve drilling positioning in two vertical directions, one horizontal direction, and one longitudinal direction, as well as servo feed for three main spindles. On each of the three drilling surfaces, there is one drilling spindle, each driven by a variable‑frequency motor. The drilling spindles are servo‑driven for precise feed control.

When the hole diameters on all three surfaces are identical, the workpiece can be fully processed in a single pass through the equipment, delivering high efficiency and exceptional hole positional accuracy. This machine is therefore an indispensable asset for quality assurance in the steel structure manufacturing industry.

3.Characters for H beam 3D drilling machine:

3.1 Overall Design and System Composition
The machine features an optimized integrated design with a high‑quality machine body and drilling units, ensuring excellent stability and rigidity during high‑speed drilling operations. The system mainly comprises the main machine, three CNC sliding tables, three drilling spindle boxes, a clamping device, a detection device, a cooling system, a scrap box, a hydraulic station, a lubrication system, and optional tool magazine and marking unit.

3.2 Main Machine Structure
The main machine is fabricated by welding square steel tubes, with structural reinforcement applied at high‑stress areas. Post‑weld artificial aging treatment is carried out to ensure the stability of the main machine, thereby guaranteeing the overall accuracy of the equipment.

3.3 CNC Sliding Tables
Three CNC sliding tables are provided: fixed‑side, movable‑side, and intermediate. These three tables are similar in construction, each consisting of a sliding plate, a slide base, and a servo drive system.

3.4 CNC Axis Configuration
The three sliding tables incorporate a total of six CNC axes, comprising three feed axes and three positioning axes. Each CNC axis is guided by precision linear rolling guides and driven by an AC servo motor with a ball screw mechanism, ensuring high positioning accuracy.

3.5 Drilling Spindle Boxes
Three spindle boxes are mounted on the three CNC sliding tables for horizontal and vertical drilling operations. Each drilling spindle box can operate independently or simultaneously with the others.

3.6 Spindle and Drive System
The machine is equipped with high‑speed precision spindles from a renowned Taiwanese brand, featuring a BT taper design that accommodates both carbide and high‑speed steel drills. All CNC axes are guided by heavy‑duty roller linear guides and driven by servo motors with roller screws, ensuring high rigidity and positional accuracy.
