This video shows the assembly of a home made hydrostatic way and slide. The restrictors are made of brass pins with a v groove machined on their axis. The restrictors have been calculated to match the pocket resistances. The pocket clearance is .001".

seems to be more hydrodynamic than hydrostatic. if hydrostatic action was achieved the table would basically float around. small nudge would cause it float basically with little to no friction. interesting project for sure would like to see a follow up

I was looking for commercial restricotors and here You have made some from brass rod. Amazing.

Very interesting and well done project to watch. Do you have any Books or resources about designing hydrostatic ways you can recommend ?

Lol it’s Adam! Slocum’s Precision Machine Design has a really good detailed section about hydrostatic bearing design, if that’s any help. Love the podcast!

Dont need a restrictor hole.just to calibrate the hole.or more better is to use a rame for do it

Very interesting that your were able to build a hydrostatic guideways. Is it possible that you can share the build plans for building the hydrostatic guideways?

I'm sorry that I forgot to drill the holes. ;-)

I don't think this achieve the real "hydrostatic" but it is a very nice project.

nice project. Are you sure about the angle of the indicator needle? Keep in mind the manufacturer specs for proper contact angles.

So is there a way to keep the oil from leaking everywhere? I'm guessing not since some of the oil will probably stick to the ways and be left behind as the slide moves around, but maybe there is a good way to prevent the oil from gushing everywhere as soon as you turn the pump on like in this video?

The intention is to let the oil leak all over. In professional machines they cover the guides under bellows and collect the oil, so you don't see it.

yes it is possible just like a hydraulic shaft using seals. i have a hardinge lathe with hydrostatics the oil is returned via lines and not a gravity catch system. both systems exist the seal system is better in my opinion

@@alexplace2001 Interesting, so this means the pro machines must be operated in strict clean environments.

@@ShopperPlug I was reading in the comments about very large vertical lathe and someone said they always leak oil, dynamic seals do not hold up well with chips. Recycling the oil would only be feasible I guess when it is cleaned first. The example we are seeing here is definitely not hydrostatic as there are so seals so no pressure can be built up. Meaning it's just an automatic way oiling system, set fairly rich, LOL.

Hello, what about using carburetor nozzle as a restrictor, have you tried it

@woozhi9218 2 жыл бұрын

So its constantly pumping oil when you move it?

Nice, you should be able to achieve nanometer to sub-nanometer tolerances... would be great if you made a tutorial on how to design and implement Hydrostatic ways.

@leonhardwolf9486 Жыл бұрын

i think you mean micrometer...

@ShopperPlug Жыл бұрын

@@leonhardwolf9486 You obviously have no idea for what and why "Hydrostatic ways" are used. Put it simply, if you want single digit nanometer (sub micron also known as micrometer) tolerances, Hydrostatic ways are the way to go.

awesome, congratulations, thanks! been thinking about it for a long time. too long.. a few questions therefore.. what do you use for pumping? how much flow and what pressure? intermediate tank or just pump? any pressure ripple? what oil are you using? could you point at the info for pad and restrictor calculations? Tribology ABC?
