Description of CNC 3D Drilling Machine
Common use machine for drilling beam’s web and flanges simultaneously, stroke of spindles are self-controlled. There are 7 CNC axes. Each spindle can do movements by horizontal coordinates and realize auto drilling feeding, which ensures drilling simultaneously on three sides of H-beam. The holes in the holes group can be drilled with the moving of spindles while the work-piece stays. It adopts roller in-feeding which contains measuring disk to ensure work-piece precise positioning.
