Gun Drilling Machine  KGD series

Boring spindle diameter:130mm Spindle speed:2500min-1 Table size:2000×2200mm Table maximum loading capacity:20000Kg

Only this machine performs integrated machining (Gun Drilling, Spot Facing, and Drilling)

  • Both spot facing and gun drilling are done by the gun drill spindle and boring spindle in one setup.
  • Boring spindle enabling high efficient machining of difficult-to-cut materials with its high torque, high power, and high rigidity, as with the latest KBT series
  • Gun drill, with drilling diameter of 5 to 42 mm, having maximum machining length of 1000 mm for KGD-1411Z and 1650 mm for KGD-2013
  • The high-accuracy rotary table can index every 0.001° and corresponds to angular holes.
  • Equipped with whip guide (drill steady rest) even spacing mechanism effectively suppressing drill deflection
