          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.
          • Optional I.D. grinding wheel provides more flexible applications.
          Plunge Grinding Examples
          The wheel spindle can be quickly set up for plunge grinding.
