The machine can perform multi-face machining applications to reduce fixture clamping and machining time.

 

The NH 800B is specially designed to meet high precision and high-performance machining demands.

 

Reliable Automatic Tool Change

 

  • Servo motor driven tool magazine shortens tool search time.
  • Short tool change arm with low moment of inertia design.

 

Central Chip Disposal System

 

  • Chip removal design assures the chips to drop directly to the conveyor.
  • Dual chip augers are utilized for efficient chip removal.
  • Dual chip augers are utilized for efficient chip removal.
  • Heavy duty coolant pump.

 

High Rigidity Structural Design

 

  • One piece T-base foundation with rib construction for unprecedented rigidity.
  • Spindle headstock is made of one piece casting to ensure cutting rigidity and accuracy during long-period machining.
  • Stepped castings design on X-axis to increase the cutting rigidity.
  • Dual-wall column design for eliminating possible thermal deformation.

 

High Rigidity Roller Guideways

 

  • Oversize roller guideways increase rigidity and precision.
