Features
Greater material removal with deeper cuts
Spindle speed is the highest in its class at 4,000/min
Spindle speed 4,000/min Maximum torque 2,793 Nm (285 kgf-1) High power machine with maximum output 45 kW.
The spindle motor and reduction gear box are located at the top of the ram.
The spindle is driven by a two-speed helical gear.
High precision cross-rail positioning made possible by 0.001mm increment NC command
Equipped with a big 400mm square ram
A powerful 400mm square ram enables powerful cutting.
Heavy duty φ130mm main spindle is supported by double row cylindrical roller bearings
It adopts oil mist lubrication for the bearings. In addition, the cooling oil is circulated around the bearing housing.
Uses tool lock with self-lock
#50 Spindle taper / Flange dual contact system (BIG plus) as standard
It improves surface finish quality and enables heavy duty milling with a long tool.
