Hydrostatic ways, by comparison, do not have this contact. In a hydrostatic system, the guideways use a pressurized film of oil, with pockets in the way system. Features of Hydrostatic Slides • Very low friction, no friction at positioning • Movement Hydrostatic guideways can compensate for forces resulting from weight.

Actually I believe that hydrostatic means a hydraulic lift. Anyways, hydrostatic floated on filterd refrigerated super clean oil and were for particularly acurate machines where the accuracy was so important wear was unthinkable.

In the other thread, the idea was to use cylindrical ground round way bar for ease and trift and then have the carraige slide back and forth on hydrostatic linear bearings that would get pressure supplied to them from some external source.

They can take catting force, many machines have them, claiming faster rapid rates, more accurate moves, etc. In addition, grinding wheels will stay sharp longer. Its obvious you dont have a clue about how fast hard turning is as compared to grinding.

This gives better damping during hard turning and interupted cutting and will produce better surface finish, part rounds, guudeways and tool life.

But to be fair, they say it needs the right kind of work These kinds of bearings are used in hydrrostatic ultra-precision machines – for example Moore grinders. Bookmarks Bookmarks Digg del. Hydrostatic Linear Motor Guide The PM Flow Controller makes it possible for machine builders to easily integrate custom hydrostatic systems into both new and existing machines.

The small bearing diameter in combination with high surface speed allows the use of CBN wheels even for undercuts in a camshaft application. Isn’t the crank bearing on most car engines a hydrostatic bearing being fed off the oil pump? Bob, Thanks for the info. Submit your feedback Your comments about this page Please leave your contact information if you would like a response. These machines have the advantages of true hydrostatic ways without the problem of a lot of oil oozing out and needing recovery.

That said, my Machinery’s Handbook says very little on them except that they should not be attempted without special knowledge and understanding of complex design issues that can only be gotten from specializes guiedways unspecified! There is a market for these machines but it definitely is not in a jobbing shop. In addition, high speed operation as well as tight stiffness and damping requirements are obtainable. The world’s largest gear gujdeways profile grinding machines use hydrostatic bearings.


Steel profiles Applications Mechanical engineering elements.

Machine Tool Preventive Maintenance. Hydrostatic if maintained is long lasting. Or rather, why are they so rare? Linear motors are used on high-speed machine tools with high acceleration and slide speeds.

The late ‘s and hydrostaic Lucas machines had “air over oil hydrostatic ways” The air picks up oil and is then applied at moderate pressure to the moving member. They are used to do final machining on both molding surfaces with a 0. Anyway, I’d love to learn more about it if you could get picts that would be great!

Hydrostatic guideways

And has the worst rating and reveiws hydrostafic I’ve ever seen on Amazon! The sliding parts are allowed to move and get virtually no wear due to a pressurized oil film between them.

Engine bearings Plain bearing shells Bushings Turbocharger bearings Thrust bearings Industrial bearings Thick-walled bearing Tilting pad bearings. Nausiatingly long weeks of lining them up.

Hydrostatic Slides

This is an example of a hydrostatic spindle designed for high speed grinding with CBN grinding wheels. Products by Type Machine Tool Gauges. That’s about as VooDoo and I’ve ever known Machinery’s to get! They hold hydrotsatic tolerances and repeat them from part to part in materials hardened to about 50 Rc.

There is a time and a place.
