CBN Hydrostatic Grinding Spindle Systems
This is an example of a hydrostatic spindle designed for high speed grinding with CBN grinding wheels. The small bearing diameter in combination with high surface speed allows the use of CBN wheels even for undercuts in a camshaft application.

The world's largest gear and profile grinding machines use hydrostatic bearings.
Hydrostatic Grinding Spindles with Integral Motors
- Very low friction will heat the spindle only slightly. Nearly all motor power gets to the
workpiece.
- Heat that is generated is moved immediately out of the spindle area with the oil and
cooled in the chiller.
- No vibration from roller bearings for extremely smooth operation.
- Excellent damping of vibration during grinding process, resulting in superior surface finish and workpiece accuracy. In addition, grinding wheels will stay sharp longer.

Application: Hydrostatic Linear Motor Guide
Linear motors are used on high-speed machine tools with high acceleration and slide speeds. For slides with linear motors, HYPROSTATIK has developed hydrostatic guideways that have no wear, excellent damping characteristics, high stiffness and much lower friction when compared with ball or roller rails.
