Features of Hydrostatic Grinding Spindles with Motor
• 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. • Very high axial and radial stiffness, allowing required dimensions to be reached faster and more precisely. Excellent roundness of grinding diameters. • High load capacity. • Stiffness is independent of speed and load, grinding and dressing can both be performed at maximum speed. • Wear-free because there is no contact between moving parts when in operation. • No loss of accuracy, even under full load at maximum speed. • Not sensitive to grinding grit or other contamination – the bearings are flushed continuously. • Gap is sealed with a compressor air lock which keeps the oil in the spindle and keeps machining coolant and chips out. • The spindle is supplied with a properly sized hydraulic power unit with chiller. The system is designed to protect the internal bearings should electrical power fail.
