ANGULAR CNC CYLINDRICAL GRINDER
The grinding wheel spindle designs by high rigidity, low temperature raise and non-contact hydro-static bearing which makes accuracy less than 0.001 mm.
Spindle Head :
- Spindle head is driven by servo motor which provides variable speed change.
- Both fixed type and non fixed type spindles are available to meet various applications.
The wheel spindle can be quickly set up for angular grinding.
