X-axis, Z-axis guide rails

l Double rectangular sliding rails, precision grinding treatment, aging treatment, quenching treatment.

l X axis is equips with two pieces pin roller heavy load linear guide, used to supporting  the worktable.

T-slot worktable(X axis)

l The horizontal travel is 400mm;

l driven by servo motor, servo reducer and ball screw; 

l Worktable dimension:4000X600mm; 

l worktable loading capacity : 6tons.

l 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：

l 1.Supporting the drill bar,

l 2.Ensure drilling accuracy,

l 3.Reducing the drill bar vibration.

Oil pressure head

l Using for the cutting tool guiding, oil supplying, supporting. using ordinary motor to drive its axial movement;

l The oil pressure head spindle can be pushed out and retracted under the control of the hydraulic system;

l the oil pressure head can be automatically locked on the machine bed by the hydraulic press board.

Workpice clamping

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