SB-20R type N
The gang-type tool post model exclusively designed for non-guide bush suited to short parts machining.
- The non-guide bush type incorporates a spindle sleeve slide guideway structure for higher spindle rigidity.
- A unique slanted dovetail slideway structure for insreased rigidity of the tool post.
- 4 types of tool posts are available to allow for a tooling layout most suited to the required machining applications.
