Product feature: 1. Equipped with three drilling head, which can provide high efficient drilling capacity with wide range of hole diameters. All these 3 drilling units can work simultaneously on the web and flanges of the beam. 2. Three drilling head can drill holes simultaneously, and adopt self-controlled stroke drilling head. No need to set thickness of work piece and length of drilling, automatically finish the transfer of rapid feeding and work feeding, and with high efficiency.3. CNC Controlled marking unit being equipped on the unloading roller to mark pre-programmed numbers/characters on the flange of the beam. The marking depth is 1.5mm, which is clear enough after surface treatment like sand/shot blasting, and HD Galvanizing.4. PLC systems, LCD screen display, programming Microsoft based on WINDOWS platform, fast and convenient programming, and visual previewing.5. Programming Microsoft is not depend on CPU equipment, can be installed in any computer to carry out programming off-site, direct copy or network transmission to the equipment to realize.6. Each drilling head, equipped with professional main shaft speed-reducing-motor from famous products abroad.7. Main machine, hydraulic pressure, electric components are famous products domestic and abroad.Specifications:Work piece sizeH-beams Max.
