Kuraki KGD Series

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.
  • Capable of machining up to hole diameter 5~42 mm(0.20” ~1.65”) and length 1650 mm(64.96”)
  • The high-accuracy rotary table can index every 0.001° and corresponds to angular holes.

Process Includes 3-Axis Machining and Gun Drilling Machining

Integrated machining can be done effectively in one setup by arranging the gun-drilling spindle parallel to the boring spindle. Various boring operations are also available by ATC.
