INFORMATION
The SR-20JII Type B improves upon the long-serving SR-20J model, offering increased rigidity, accuracy and versatility through a combination of improved engineering and expanded functionality.
Combining a 6-tool turning platen with a 5-spindle cross drilling unit and an 8-spindle back working tool post, the SR-20JII boasts impressive tooling capacity allowing for a huge range of machining options.
The updated design features dovetail slideways for the X1, Y1, Z2 and Y2 axes improving the machine’s rigidity – ensuring stable, repeatable results even when cutting the most challenging materials.
The sub-spindle speed, power and accuracy have also been increased by adopting a built-in spindle motor offering 10,000 rpm and 3.7Kw.
The SR-20JII Type B represents the latest evolution in 20mm sliding head machining – and the most advanced technology of its type on the market.
BENEFITS
- Improved metal removal rates with increased power on driven tools and sub-spindle
- Switchable between guide bush and non-guide bush modes
- Main and sub spindle speed 10,000 rpm / power 3.7Kw
- Reduced cycle times due to more overlapped machining possibilities
- Improved rigidity due to dovetail guideway structure
- Increased flexibility due to more tooling configurations
- Improved ergonomics with large cutting room and headstock “up and over” doors
- Increased accuracy due to built-in spindle motors
