HYDROSTATIC GUIDEWAYS PDF
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.

Hydrostatic Leadscrews – Speed comparable to a linear motor – Very low friction when machining, virtually frictionless during positioning guidewqys Steps in the 0. Have any of you seen a lathe that had the ways refit with Hydrostatic guideways linear bearings rails?

Hydrostatic C-guide rails with screwmounted guide plates Speed: They hold these tolerances and repeat them from part to part guuideways materials hardened to about 50 Rc. Linear motors are used on high-speed machine tools with high acceleration and slide speeds. Table load, I believe is 10K lbs Applications Automotive Engineering Building and construction machinery Linear guides Mechanical-engineering.
Linear guidways are totally different Hydrostatic guideway unit with integrated linear motor Run-off precision: Other than that it sounds like these things are just plain bearings with a hydraulic pump squeezing fluid out guodeways them. Machine Tool Preventive Maintenance.
I have a tremendiously huge amount of experience with hydrostatic ways.
Bob, Thanks for the info. 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 PM Flow Controller makes it possible for machine builders to easily integrate custom hydrostatic systems into both new and existing machines.
Generally, the bearing surfaces are made of granite and the oil is fed under high pressure through either an orifice or, in more recent times, a porous graphite disk. Provide feedback or ask a quick question about this item.
The selflocking eccentric cam gear guarantees a simple handling with a maximum of reliability. I worked at Husky Injection Molding before starting my own business and they are a large consumer of Hembrug Lathes both in Europe and In Canada in the facilities where they make parts with molding surfaces. In addition, high speed operation as well as tight stiffness and damping requirements are obtainable.
The moving member actually rises about. I love the idea, though I’m sure that there would be a gotta or two along the development course.
Let me know how this turns out. In storbook machine shop the siding member continually floated in a magical super clean oil and one perfectly accurate metal part never touched the other perfectly accurat part. The orifices are cross-connected to provide stiffness. I dealt with ball screw grinders with hydrostatic ways. Please leave your contact information if you would like a response.
There is a market for these machines but it definitely is not in a jobbing shop. The cross-connection is the key to stiffness – increasing pressure on the top due to cutting forces will cause the pressure at the orifice to increase and this will increase the pressure on the bottom due to cross connection to compensate.
From everything I read, it sounds like these things should be dog simple and really cheap.
