Machine Feature:
1. The whole machine is optimized integrated design, with high quality machine body and drilling units, which ensure highstability and high rigidity when high speed drilling. This machine is mainly composed of main machine, CNC sliding table (3), drilling spindle box (3), clamping device, detection device, cooling system, scrap box, hydraulic station, lubrication system,Tool Magazine(optional), marking unit (optional).
2. The main machine is welded by square pipe. The structure of main machine is strengthened where the stress is greater. After welding, artificial aging treatment was carried out. All these ensure the stability of the main machine and then ensure accuracy of the whole machine.
3. There are three CNC sliding tables: fixed side CNC sliding table, movable side CNC sliding table and intermediate CNC sliding table. The three sliding tables are similar in structure and are composed of sliding plate, sliding table and servo drive system.
4. There are six CNC axes on the three sliding tables, including three feeding CNC axes and three positioning CNC axes. Each CNC axle is guided by precise linear rolling guide, driven by AC servo motor and ball screw, which ensures positioning accuracy.
5. There are three spindle boxes, which are mounted on three NC sliding tables for horizontal and vertical drilling. Each drilling spindle box can drill both separately and simultaneously.
6. Used high-speed precision spindle from Taiwan’s well-known brand, model BT, which can meet the using demand of both hard alloy and high-speed steel drill. Every CNC axes are guided by the heavy loading roller linear guide, driven by the servo motor and roller screw which ensure the rigidity and positional accuracy.
7. Also equips with hydraulic tool cylinder, using hydraulic –disc spring to do automatic tool de-clamping, tool pulling, with tool status monitoring device to check the tool clamping and effective safety co-locking protection device. Easy to change tools. The spindle is driven by spindle servo and timing belt, reducing ratio i=2 , spindle speed is 0～3000r/min, large rotation speed range.
8. The workpiece is fixed by hydraulic clamping method. There are five hydraulic cylinders, which are clamped horizontally and vertically. Horizontal clamping consists of fixed side datum and moving side clamping, fixed side datum is fixed, moving side clamping is driven by large cylinder sliding table, guided by linear guide rail, moving towards the fixed side to clamp the workpiece horizontally; vertical clamping is on both fixed side and moving side, and each cylinder drives the pressure bar to move up and down in four positions. The workpiece is clamped vertically.
9. The machine is fed by a NC carriage. The NC carriage is decelerated by the servo motor through the reducer and then passes through the gear rack to driven a laser alignment device. When the workpiece is fed in, the workpiece can be detected and then fed back to realize the precise positioning of the workpiece.
10. Cooling system: using air-fog cooling, with the internal and external cooling. Each drilling spindle box is equipped with its own external cooling nozzle and internal cooling joint, which can be selected according to the needs of drilling holes. Internal and external cooling can be used independently or simultaneously.
11. Chip collecting box: Universal caster guide, easy to carry.
12. The hydraulic system is for auto tool device of ram type drilling box,Horizontal clamping, vertical clamping, side pushing and power raceway, unified oil supply; all the hydraulic units are from imported brands or joint venture companies, for easy maintenance and solving oil leaking, all the design adopts accumulative valves.If marking unit is equipped, there is also an independent hydraulic station for marking unit action.
During sample demonstration sessions, the CNC beam plate metal drilling, marking, and shearing machine effectively showcases its processing capabilities with standard H-beam samples (featuring various flange widths and web thicknesses) as well as channel steel samples of different sizes. The samples used in these demonstrations clearly highlight the machine’s ability to deliver precise hole placement, smooth threaded tapping, and distinct marking patterns, thereby thoroughly demonstrating its high accuracy and dependability in practical applications.
The High-Speed CNC H-Beam Drilling, Marking, and Shearing Machine is primarily utilized in steel structure fabrication workshops and bridge construction projects. In steel structure fabrication, it performs precise processing on H-beams used in framework and support structures, providing a solid foundation for the stable assembly of steel frameworks. In bridge construction, it executes high-precision drilling operations on H-beams, enhancing the structural integrity of bridges and ensuring their ability to withstand long-term loads. With its outstanding operational efficiency, the machine consistently supports these vital infrastructure sectors, facilitating the seamless progression of related projects.
