Hydrostatic bearings - Import export

Hydrostatic bearings are characterized by practically frictionless movement. The corresponding linear guides are free from stick-slip effects and there is practically no wear on the guides. Gases (mostly air) or liquids (mostly oil) can be used as the carrying medium. Air-bearing guides are ideal, for example, for clean room applications or at high sliding speeds. If oil is used as the carrying medium, higher carrying forces can be achieved with the same size and better damping properties. Various designs are available, which can be customized at any time to meet special requirements in terms of installation space, load capacity, guide length / table diameter, drive type, position measuring system, etc.

To create ideal conditions in terms of rigidity and damping for multi-axis machining, the series was equipped with hydrostatic (oil) bearings. By using diamond tools, optical surface quality can be achieved on a wide range of materials like crystals, nonferrous metals and plastics, even with complex geometries. Similar to the MMC 600/900 air bearing machines, the basic setup can be equipped with various accessories. The basic setup consists of 3 linear axes and can be upgraded by additional rotary, tilt or spindle axes to 4, 5 or 6 axes. Accessories, like different spindles, vacuum chucks, palleting systems, 3D touch probes for workpiece measurement, tool changer and automated tool setting, allow an effective use of the machine. Besides further accessories, there is the possibility to develop customized solutions, to adapt the machine to your needs.Please do not hesitate to contact us.

The output shaft of the HSH swivel motors has radial and axial hydrostatic bearings. Here, radially and axially arranged bearing pockets are supplied with pressurized oil via a separate pressure connection. As a result, the output shaft is centered radially and axially between liquid cushions and all metallic contact surfaces are permanently separated from each other by a thin liquid film. This eliminates wear caused by metallic friction in any operating state, even at zero speed compared to hydrodynamic plain bearings. In conjunction with highly dynamic control valves and angle of rotation sensors, these actuators are preferably used in controlled systems in which disturbance variables such as friction and the stick-slip effect must be reduced to a minimum. Furthermore, due to the lack of internal seals, they are ideal for test series with large numbers of load cycles where an interruption, e.g. due to the replacement of internal seals, is not permitted.
