Features
Outstanding accuracy
The spindle core cooling that suppresses thermal displacement
- It reduces steps and bites on the machined surface.
- High-precision machining is possible at the speed range from low to high.
Vertical Spindle Structure
The sample surface is divided into areas and processed with 5 tools.
Rotation speed to 4,000 to 8,000 min-1 for each tool, the step at the area boundary is 3.5 μm at the maximum.
Thermo-stabilizer column maintains geometric accuracy without being affected by changes in environmental temperature
- Setup is possible without worrying about temperature changes over time
- The origin does not go out of order even during long-time machining, reducing the frequency of centering.
Prominent cutting ability
Powerful heavy cutting on both vertical and horizontal axes

Versatile performance
Many kinds of attachments and package options available
You can select the attachment according to the shape of part of workpieces such as narrow part, inclined surface, free curved surface, or to the machining method like high-speed machining, high-precision machining etc.
Example of attachment according to part shapes
| Right angle head | Powerful Right angle head High Right angle head Small Right angle head |
|---|---|
| Extension head | Extension head (long) Extension head (short) Extension head (small diameter) High speed Extension head High speed Extension head (built-in motor) |
| Universal head | Universal head (offset type) Universal head (center head) High speed universal head |
| 5-axis machining head | 5-axis (NC2-axis) attachment |
