Machine structure for high speed feed and high rigidity
- Highly rigid 3-point supported bed
Easy installation thanks to bed that does not twist.
Supporting stable, high accuracy over a long period. - Ball screw bracket
The ball screw brackets at both ends of the X-Y-Z axes are reinforced and combined for highly accurate drive and positioning. - Ball screw cooling
X-Z axis ball screw cooling and Y-axis motor bracket cooling are standard. Assuring stable accuracy during high rates of operation. - Indexing table, pallet
Indexing table uses curvic coupling for high-accuracy indexing.
Std: 1 degree
Opt: NC 0.001°
Pallet seating surface uses a taper cone system for high accuracy positioning and high durability.
High-speed operation that reduces non-cutting time
- Rapid traverse: 60 m/min (X-Y-Z axes)
- Rapid acceleration: 0.7G (maximum)
- Tool change: 2.0 sec (T-T) / 4.4 sec (C-C)
- Table indexing:
2.0 sec (MA-600HⅡ 1 degree indexing 90 degrees)
2.5 sec (MA-600HⅡ 0.001 degree indexing 90 degrees) - APC time: 12 sec (MA-600HⅡ)
Ideal performance levels from a variety of spindles for a wide range of applications

Outstanding dimensional stability with long-run machining of large workpieces
Manageable Deformation—Accurately Controlled
Thermo-Friendly Concept
Dimensional changes of less than 8μm over time in a wide machining range (actual data with room temperature change of 8°C [TAS-C applicable])
In addition to maintaining high dimensional accuracy when room temperature changes, Okuma’s Thermo-Friendly Concept provides high dimensional accuracy during machine startup and machining restart.
To stabilize thermal deformation, warming-up time is shortened and the burden of dimensional correction during machining restart is reduced.
