2.The machine has 3 drilling units, all the 3 drilling units can work simultaneously on the web and flanges of the beam. It can provide high efficient drilling capacity with wide range of holes diameters.
3.Each of the spindles adopts the technology of self-controlled feeding, it can moves along the two coordinates and realize drilling feeding, which ensure three spindles drilling simultaneously on the three sides of an H-shaped steel.
Machine advantages

The web of beam is supported by many hydraulic support blocks in order to prevent deformation during drilling.
Rollers type feeding, AC servo motor powers the feeding with dynamic speed control enabling the best drilling condition.
The two horizontal drilling heads are different. One is fixed and the other one can do the horizontal movement which is adjustable in accordance with different web height.
Imported external atomizing cooling system can prolong the drills life
The control system consists of industry PC with PLC and control modules. Individual control console and electrical cabinet are fixed beside the main machine.
Remote diagnosis and Ethernet connection is also available.
