CNC H beam drilling machine 
1) high precision positioning , dolly feedingdriven by servo motor
2) 3D drilling line machine 
3) Composed one CNC beam line together with CNCband saw machine 

Features:
a)  Equipped with three drilling spindles,the drilling process finished when the work piece going through the equipment. 

b)  Three drilling spindles can drill holessimultaneously, equipped with self-controlled stroke drilling spindles. 

c)  No need to set thickness of work pieceand length of drills, with automatic speed conversation, high efficiency fromrapid feeding to work feeding.

d)  CNC & PLC control systems, CRTdisplay, operating software based on WINDOWS platform, simply and convenientprogramming and visual preview. 

e)     High-grade atomizingcooling system, prolong the drill’s work life.

f)  Each drilling spindle, equipped withprofessional gear-motor from famous products.

g) Main primary hydraulic pressure, electriccomponents are domestic and international famous products.
