Twin Barrel Hole Drilling Machine

X-axis, Z-axis guide rails

●Double rectangular sliding rails, precision grinding treatment, aging treatment, quenching treatment.
●X axis is equips with two pieces pin roller heavy load linear guide, used to supporting  the worktable.

T-slot worktable(X axis)

●The horizontal travel is 400mm;
●driven by servo motor, servo reducer and ball screw; 
●Worktable dimension:4000X600mm; 
●worktable loading capacity : 6tons.
●The worktable bed body and the tool bed body adopt divided structures, which are assembled together with high strength bolts and are positioned by the cone pin.

Drill bar rest

3 groups, 
Function：
●1.Supporting the drill bar, 
●2.Ensure drilling accuracy, 
●3.Reducing the drill bar vibration.

Oil pressure head

●Using for the cutting tool guiding, oil supplying, supporting. using ordinary motor to drive its axial movement;
●The oil pressure head spindle can be pushed out and retracted under the control of the hydraulic system;
●The oil pressure head can be automatically locked on the machine bed by the hydraulic press board.

Workpice clamping

●with 2 sets V type block to clamp the workpiece.
