Product Features

1. This machine tool is primarily composed of the main machine body, CNC feeding system, material conveyor, electrical system, hydraulic system, cooling system, lubrication system, waste bin, and other components. Adopting a fixed bed structure and a movable workpiece configuration, the machine tool is well-suited for the processing of large-scale H-beams. It facilitates continuous production operations and features a high level of automation.

2. The drilling machine body comprises the bed, CNC sliding table assemblies, supporting devices, upper pressing devices, side pressing devices, and detection devices. The components of the CNC sliding table include the fixed side, the movable side, and the upper-unit CNC sliding table. The sliding table assemblies consist of a sliding plate, a sliding table base, a spindle headstock, a high-speed mechanical spindle, a tool cylinder, a variable-frequency motor, a servo motor, linear guides, and lead screws, which are specifically designed for the drilling of H-beams.

3. The CNC feeding system comprises brackets, gears, racks, servo motors, reducers, and manipulators. The servo motor drives the manipulator to move the H-beam in the X-direction, enabling the feeding of the H-beam and precise positioning of the workpiece.

4. The material conveyor is categorized into an in-feeding conveyor and an out-feeding conveyor. The in-feeding conveyor consists of conveyor brackets, support rollers, and side-pushing devices, which are designed to carry profiled steel blanks, position the blanks in the Y-direction, and coordinate with the CNC feeding device for material feeding. The out-feeding conveyor is composed of material channel brackets and support rollers, specifically used to carry finished workpieces.

5. The cooling system employs internal and external cooling methods, utilizing oil mist to cool the borehole. Its advantages include a minimal coolant volume, which contributes to cost efficiency, environmental friendliness, and reduced drill bit wear.

6. The hydraulic system serves to supply power to the upper pressing device, side pressing device, tool cylinder, and other related components.

7. The pneumatic system is designed to provide power for the manipulator, testing cylinder, and similar equipment.

8. The lubrication system employs a combination of centralized lubrication and manual lubrication. Centralized lubrication is primarily utilized for timed and quantitative lubrication of the main linear guides and lead screws.

9. The machine tool's control system comprises a host computer, PLC, and other associated components. Programming Method: Processing programs are generated by inputting CAD drawings or processing parameters via a USB interface or keyboard. These processing programs can be stored, retrieved, displayed, and communicated at any time based on part numbers. The machine tool is capable of not only realizing manual adjustment and control of individual processing parameters but also achieving fully automated control for the entire processing workflow.

During sample demonstration sessions, the CNC beam and sheet metal drilling, marking, and shearing machine can effectively demonstrate its processing capabilities when operating on standard H-beam samples—with different flange widths and web thicknesses—and channel steel samples of various dimensions. The specimens displayed in these demonstrations clearly illustrate the equipment’s ability to achieve accurate hole positioning, smooth tapped threads, and clear marking patterns, thus fully reflecting its high precision and reliability in practical application scenarios.

The High-Speed CNC H-Beam Drilling, Marking and Shearing Machine is primarily deployed in steel structure manufacturing plants and bridge construction projects. Within steel structure workshops, it provides precision machining for H-beams used in framework and support structures, thereby laying a solid foundation for the stable assembly of steel structures. In bridge construction scenarios, the equipment performs high-precision drilling operations on H-beams—this not only improves the structural stability of bridges but also enables them to effectively withstand long-term loads. With excellent operational efficiency, the machine delivers reliable support for these key infrastructure sectors and ensures the smooth advancement of related projects.
