NC Surface Grinders
NC Surface Grinders - SSG Series
NC surface grinder with a five-bearing super-precision spindle, combining linear guideways and box ways for both accuracy and rigidity.
Made in Taiwan
- Five super-precision angular contact bearings support the spindle under heavy grinding loads
- AC servo drives for high torque, fast traverse and repeatable positioning
- Linear guideways combined with box ways for accuracy and rigidity together
- Wheelhead automatic downfeed resolution of 0.0001 mm
- Four table sizes, grinding length up to 1015 mm
- Rigid structure with an ergonomically planned operating layout
