SB-20RⅡ
The latest SB-R model was born in pursuit of the functionality and performance needed today, based on the series’ traditional high-rigidity structure.
- A unique slanted dovetail slideway structure for insreased rigidity of the tool post.
- A 1.5/2.2 kW spindle motor is employed on the sub spindle to improve output. Even the sub spindle realizes a maximum speed of 10000min⁻¹.
- Two NC machines to choose from
