About Construction Engineering Bridge Project Use Cnc Beam Drilling Machine Line BT40 Main Spindle

Components of CNC Drilling Machine Line

The CNC drilling machine line is primarily comprised of key components, including the main machine frame, CNC feeding system, out-feeding conveyor, cooling system, hydraulic system, pneumatic system, lubrication system, electrical system, and a scrap material collection cart. The production line features a fixed-bed design paired with a movable workpiece-carrying structure. This configuration provides 3D drilling capability, enabling fully automated production processes and ensuring efficient, consistent, and reliable manufacturing operations.

1. Main Machine Body

The main machine body is primarily composed of a base, bed, movable sliding table, headstock, upper pressing device, side pressing device, and a row-type tool magazine. The bed is characterized by exceptional rigidity and stability, enabling it to withstand the forces and vibrations generated during high-speed machining operations. This structural robustness ensures that the machine tool maintains consistent machining precision throughout all operational stages.

2. Cooling System

The drill bit is cooled using an aerosol cooling system, which combines compressed air with cooling water. This method provides advantages such as minimal coolant usage, enhanced cost efficiency, environmental sustainability, and reduced drill bit wear. A flexible nozzle is mounted on the headstock, allowing convenient adjustment of the spray position to ensure continuous and effective cooling of the drill bit during operation.

3. Lubrication System

This system utilizes a hybrid lubrication arrangement, integrating both centralized and manual methods. The centralized lubrication unit provides precise, scheduled lubrication to designated linear guides and lead screws, while all remaining lubrication points are serviced manually.

Precision Drilling for Large-Scale Projects

Designed for the complexities of construction and bridge engineering, this CNC Beam Drilling Machine achieves top-tier accuracy-positioning to within 0.08 mm-across an extensive 12-40 mm drilling diameter. Its high-rigidity frame and automatic coolant supply system ensure consistent, reliable performance, even when handling heavy-duty steel structures or high-output operations.


Effortless Automation and Control

Supported by Siemens PLC control and a user-friendly touchscreen HMI, the CNC Beam Drilling Line offers seamless, fully automatic operation. Operators can input G-code or NC code for complex machining processes, while automatic bar feeding, centralized lubrication, and emergency safety features maintain both productivity and security.


Versatility and Software Compatibility

Engineered for flexibility, the system processes workpieces from 2000 mm up to 12,000 mm long, and up to 1200 mm wide. It supports 3-axis simultaneous control for fast, complex drilling tasks and integrates easily with Tekla and AutoCAD, streamlining data transfer for construction, fabrication, and bridge building.
