CNC Plunge/Angular Cylindrical Grinder - Jainnher Machine Co
The spindle is supported by oil membrane, as almost without metal contact between bearing and spindle, the spindle is less wearing and has a long and lasting life. The oil membrane between bearing and spindle increases contact area, and therefore, workpieces can reach the highest precision and roundness. Oil menbrane absorbs vibration during grinding process,the workpieces will be kept the best surface roughness.

Hydrodynamic Bearing Series (Economical high precision Series): Fine hand scraped hydrodynamic bearings made of steel and phosphor bronze alloy with oil lubrication, firmly maintains grinding spindle high precision rotation and rigidity to stand heavy duty grinding in minimum gap.
What’s “Hydroviscous” Spindle Damping? | Modern Machine Shop
Nov 02, 2015 · GMN's spindle technology uses "hydroviscous" damping to reduce natural vibrations on machine tools and grinding machines. “Hydroviscous” spindle damping technology is said to reduce natural vibrations as much as 65 percent compared to conventional spindle designs, improving a spindle’s dynamic stiffness to boost cutting and grinding ...
Hydrostatic spindle - WEISS Spindeltechnologie
Hydrostatic spindles or hydrodynamic spindles as tool machine spindles or main spindles have a very good radial accuracy. However, they have disadvantages in terms of rigidity and purchasing costs compared to spindles with roller bearings.With hydrostatic spindles, the shaft is guided by the externally generated static oil pressure in the glide elements provided with oil pockets.

Hydrostatic Grinding Spindles - TAC Rockford
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.
EXPERIENCE WITH FOUR TYPES OF GRINDING MACHINE SPINDLE
The machine on which it was decided to fit a hydrostatic air-bearing grinding spindle was the Wickman-Scrivener Model 824 Surface Grinder. This is of the type commonly in use for both production and toolroom machine shop precision work.
Do you need hydrostatic spindles for internal grinding?
JUCENTER - Grinding machine: JUNKER Group
The JUCENTER CBN high-speed grinding machine combines mutually complementary grinding possibilities under one hood. Instead of lining up individual grinding machines for different grind-ing tasks, both grinding processes take place in two separate clamping set-ups on one machine. The result: highly efficient grinding – all with top precision.
Products - IZUMI MACHINE TOOLS
