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.

Angular Grinding Examples
The wheel spindle can be quickly set up for angular grinding.
