Linear Slide
Depending on the table top, the extensive hydrostatic bearing is dimensioned for the maximum diameter.
Due to the hydrostatic guiding, there is no wear surface, which means optimal suitability for very demanding and highly precise processing.
The additional sliding coating on the wrap-arounds as well as on the bottom hydrostatic surface ensures reliable performance and the best possible emergency operation functions.
The quiet, wear-free drive at maximum diameter is effectuated by a large external crown gear with helical gearing and a low backlash precision gearbox.
The integrated duo drive system (two electronically coupled servo motors) ensures an excellent drive behavior.
The rotary axis is designed for infinitely variable positioning in each angular position and as controlled NC-axis for rotary milling.
The centrally located rotary encoder with up to 36,000 signals (further resolution possible via the control system) guarantees a highly precise angular positioning and perfect precision of change even with very large workpieces.

Concentricity in the μ range is ensured by the central arrangement of the pre-loaded radial precision bearings.
Hydrostatic wrap-arounds with integrated hydraulic clamping ensure the maximum transmission of tilting and tangential moments.
Due to the generous dimensioning of this clamping system, the table is friction-locked in a way which is superior to the antiquated construction principle of Hirth couplings in terms of force transmission, thus rendering this principle superfluous.

Interface to Machine
An easy connection and integration to the machine is made possible due to a central Rexroth SCHNEEBERGER SIEMENS interface ready to plug-in.

Table Top
Very strongly ribbed and stable cast construction. The table tops are optionally available in high-quality grey casting or in ferro casting. Hardened center spigots allow for the positioning of fixtures and workpieces.
Radial turnaround
Table top levelness 0.015mm
Maximum drive and bearing surface diameters for highest precision
Central hydrostatic bearing minimizes bowing of the table top.
A generous mechanical labyrinth seal of the compound slide prevents the infiltration of the finest damaging particles of dirt and thus ensures a long service life.
Through a central optional rotary union, customer-defined media such as hydraulics, pneumatics, or electricity can be guided through the center of the table with continuous rotation.
FEM method table top optimization is standard.
Asymmetrical load distribution, Symmetrical load distribution

Guide Bed
Compact, and hence space-saving, very stable machine bed. Ball screw for a traverse speed of up to 25m/min.
Maximum available with two or four linear guideways, depending on load. Feed force up to 50 kN.
Linear guides require sparing grease lubrication.
The guide bed is available in various traverse ranges.
The heavy-duty version with 4 guideways includes additional distance-coded or absolute linear measuring systems for pre-clamped fixing devices in the center of the machine bed, which guarantee safety switches integrated in the bed as limit stops.
The slightest possible deformation even with the highest loading.
Load bearing capacity of table from 10 to 500 tons.
The motors and the cable drag chain are located underneath the solid steel telescopic covers with chequer plate, to ensure that they are compact, easy to maintain, and protected against dirt.
Also available with hydrostatic bearing for best attenuation properties and freedom from wear.

Our NC-Rotary Tables are available in two versions. The N version precision and rigidity at an excellent price-performance ratio.
Another version available, the one with the hydrostatic linear axis, additionally ensures best attenuation properties for our Rotary Tables.
2 guide surfaces - 4 guide surfaces additionally, fixing devices in the center of the table.

Theoretical Rated Load of our Tables
Theoretical rated load of our Tables is clearly higher.
In general, the following applies: For longevity and precision, the decisive factor is not only rated load but rather a very big bearing diameter in proportion to the table top size.

Combinations of Bearing Types
As desired and according to requirement, different bearing types are available. We would be glad to advise you in choosing the right bearing.
Roller bearing, Hydrostatic bearing, Rotational axis, Linear axis.
