DHF 8000 Handles Roughing to Finishing

Dec. 8, 2017
Doosan Machine Tools America's horizontal machining center was designed for the processing of large, complex parts.

The DHF 8000, an 800 mm twin pallet 5-axis horizontal machining center with a nodding head. This HMC was specifically designed for the processing of large, complex parts such as those used in the aerospace, oil field, and automotive industries.


The nodding head spindle and rotary table (axis A and B) allow the DHF 8000 to handle a complete range of machining processes from roughing to finishing in a single setup. This configuration makes quick work of multi-face workpieces and the 5-axis simultaneous machining of complex shapes.


The nodding head spindle rotates through 160-deg. (up/down) and has a maximum speed of 6,000 rpm, with 960Nm (708 ft-lb.) of torque. The Y and Z axis are fitted with dual ball screws to ensure greater structural stability and accuracy, while the column is designed with high static and dynamic rigidity to provide optimum machining performance.


This scaled-up HMC can easily support workpieces weighing up to 2,000 kg (4,409 lb.), allowing them to be machined with the same precision as their much smaller counterparts. Its large working area can readily hold parts up to 1,400 mm (55 in.) diameter.


Other performance and precision enhancing elements include:

  • Glass scales for each axis
  • Cooling systems for the spindle and ball screws
  • Center through chip disposal
  • An upgraded waste oil disposal system
