Application:

This machine is mainly used for drilling of H-beam,Channel steel,box-beam etc, with CNC controls, servo motor drives the positioning ,feeding of three drilling spindle .Feeding by dolly with high efficiency and precision, it can be widely used for buildings, Bridges, power station boiler, parking equipment, ocean oil Wells tower platform, mast steel structure industry.

Machine structure and Mechanism

This machine includes main machine, CNC slide(3) ,Stoke- control drilling head(3) ,clamping,detection devices,CNC feeding dolly, infeeding andoutfeeding channel .coolingsystems, Chipping box etc.

The bed is square steel tubes weldedtogether to strengthen the larger force structure of the bed, the completion ofthe weld artificial aging treatment, these are very good to ensure thestability of the bed, thus ensuring the accuracy of the entire machine.

CNC sliding 3, respectively, thefixed side of the NC slide mobile side of the NC slide and intermediate CNCslide three slide structural similarity by the slide board, slide and servodrive system composition.
Three sliding stage with a total of six CNC axes, including three CNC feedingaxes and three CNC positioning axes, CNC axis using precisionlinear rolling guide direction by AC servo motor + ball screw drive, a goodensure the positioning accuracy.

Drilling spindle box 3,respectively, installed three CNC sliding table, drilling of horizontal andvertical directions. Drilling spindle boxes can be used alone drilling, butalso at the same time drilling.

Spindle with precision spindle rotation accuracy, high rigidity. Equippedwith BT40 taper, tool change can twist drill clamping, clamping carbide drillbit, the scope. The spindle motor drive frequency control for a wide range, andspeed in a wide range of variable speed, to meet a variety of speed demand.
