33x5.5x3.3m Machine Size 3d CNC H-Beam Drilling And Marking Machine BT40 Main Spindle

Application industry:

This machine tool is specifically engineered for drilling operations on H-section steel. It integrates three high-speed precision drilling spindles to conduct workpiece drilling, which not only ensures superior machining accuracy but also enables simple and efficient operation. As a core high-efficiency equipment unit in the steel structure industry, it is extensively applied in construction engineering, bridge construction projects, tower masts, grid structures, and other associated fields.

Specifications:

Main Machine Body:

It is primarily composed of a base, a bed, a movable sliding table, a headstock, an upper clamping device, a side clamping device, and a row-type tool magazine. The bed features excellent rigidity and stability, enabling it to bear the loads and vibrations generated during high-speed machining while ensuring the machining accuracy of the machine tool.

A total of 3 headstocks are mounted on the main machine, namely the fixed-side headstock, the mobile-side headstock, and the upper unit headstock, which are used for drilling in the horizontal and vertical directions respectively. Each headstock is capable of being operated independently and can also complete drilling operations simultaneously, significantly enhancing production efficiency. Each headstock is equipped with one set of BT40 high-speed mechanical spindles. The corresponding row-type tool magazine can accommodate up to 4 drill bits of different diameters (when no tool is attached to the spindle), enabling automatic processing of 4 different aperture sizes with a single workpiece clamping.

Three headstock units are mounted on the bed. Each headstock unit is driven by two sets of servo motors to achieve horizontal and vertical movement of the headstock, with power transmission via ball screws and guidance provided by precision linear rolling guides. During the drilling process, this equipment clamps the workpiece in two directions. Above the workpiece, a cylinder-driven clamping mechanism is installed to secure the workpiece onto the horizontal support rollers; additionally, a cylinder-driven clamping mechanism is configured to clamp the workpiece from the side.

Infeeding Conveyor

It is composed of a conveyor support, support rollers, side positioning rollers, a side pushing device, a rack, and other components. The feeding channel is designed to carry workpieces to be processed. A photoelectric switch is installed at the front end of the material channel to detect the front end of the workpiece and determine the X-direction processing datum. The side pushing device clamps the workpiece tightly and presses it against the side positioning rollers, thereby realizing the rough positioning of the workpiece in the Y direction.

Cooling System

The machine adopts an aerosol cooling method for drill bit cooling, which is implemented via compressed air combined with cooling water. This method offers multiple advantages, including reduced coolant consumption, cost efficiency, environmental friendliness, and minimized drill bit wear. Flexible nozzles are mounted on the headstock, and the spray position of the nozzles can be conveniently adjusted—ensuring the drill bit is continuously cooled during operation.

This machine tool is custom-engineered for drilling, tapping, and marking operations on H-beams, channel steel, and a range of other steel workpieces. The samples provided herein clearly demonstrate the machine tool’s capacity to achieve accurate hole positioning, smooth tapped threads, and distinct marking patterns—fully reflecting its high precision and reliability in practical application scenarios.

In steel structure workshops, this machine tool performs precision machining on H-beams used for frameworks and support structures, thereby laying a solid foundation for the stable assembly of steel structures. In bridge construction scenarios, it carries out high-accuracy drilling operations on H-beams—this helps enhance the structural integrity of bridges, enabling them to withstand long-term loads.
