The multi head drilling machine is mainly composed of foundation, column boards, beam,CNC slipway,milling box,testing device,automatic chip cleaner,circulation cooling device,hydraulic system,electrical system,etc.
Three CNC slide type drilling spindles are equipped onmovable gantry(vertical, left & right).Special machine for drilling on three sides of large H-beams and box beams.
The axial movement of 3 drilling spindles,the transverse movement of the vertical spindle on the gantry frame,the up/down movement of left & right spindles on the gantry columns are guided by linear rolling guide,driven by AC servo motor and ballscrew,balanced by hydraulic system.
The longitudinal movemant of gantry on the machine frame is guided by highrigid linear rolling guide equipped on the two sides of machine frame, driven by AC servo motor,high precision reducer and gear & rack, with hydraulic locking unit.
H-beam or box beam can be directly hoisted to the worktable. CNC operation table is equipped on the left of gantry and it can move longitu dinally with the movement of gantry,which offers convenient operation.
Adopt PLC control system and host computer. Direct transform of CAD/CAM, which is convenient for program, store, display, selection and communication.
