The NH 800B incorporates the state-of-the-art dual drive technology along with the utmost rigid structural design to satisfy high accuracy applications. The machine can perform multiface machining applications to reduce fixture clamping and machining time. The NH 800B is specially designed to meet high precision and high performance machining demands.

 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
 
Y-axis Dual Drive System
 
▲ Headstock is driven at the center of the gravity to minimize vibration. The dual-driven design restrains vibration and delivers high speed, high quality machining ability while increasing machine performance and tool life
 
High Performance Built-in Motorized Spindle
 
▲ Built-in motorized spindle reduces vibration during high-speed machining and ensures spindle life
▲ 10,000 rpm maximum spindle speed with 45 kW output delivers 623 Nm torque
▲ Micro oil-air lubrication for angular ceramic ball bearings prolongs spindle life
▲ Circulated oil jacket cooling system minimize thermal deformation, ensuring high accuracy
▲ Easy spindle unit replacement reduces maintenance time
 
High Capacity Machining Space
 
▲ ø1,300 mm x 1,300 mm largest working envelope within its rank
▲ 2,000 kg maximum loading capacity on each pallet
 
High Rigidity Roller Guideways
 
▲ Oversize roller guideways increase rigidity and precision
▲ High dynamic AC servo driven pre-tensioned ball screws, delivering high control qualities
▲ 50 m/min. rapid feedrate increase machining efficiency
 
High Precision B-axis Rotary Table
 
▲ Disc brake with damped clamping system
▲ High precision in-house pallet indexing system
▲ Discharging air jet pallet indexing system
 
Automatic Pallet Change
 
▲ 20-second pallet change
▲ Servo motor driven
▲ Simple structural design, fast reliable movement and easy maintenance
 
Reliable Automatic Tool Change
 
▲ Servo motor driven tool magazine shortens tool search time
▲ Short tool change arm with low moment of inertia design
▲ Servo motor and backlash free reducer driven tool magazine
▲ Hydraulic tool unclamping magazine
 
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
▲ Heavy duty coolant pump
● Standard;○ Selectivity;─ No More;★ Customize
