The center piece

Simple assembly with few components and very high repeat accuracy for at least one million cycles!

Pneumatic system

Only 5.5 bar air pressure is required to release the clamping studs.

Easy to handle from a logistical point of view. No differentiation between zero pins, floating pins, and free pins

Just one clamping stud type required
Thermal symmetry

Compensation for thermal expansion always symmetrical about the center axis

Highest degree of accuracy

Clearance-free fit enables a perfect form fit with a repeat accuracy of less than 2.5 μm.

Fixed zero point in the center of the table

Pitch errors can be compensated up to ±0.05 mm per clamping pot.

Clearance-free fit

The hyperstatic interface ensures axial face contact and zero radial clearance.

For comparison:
classical systems

Difficult compensation for thermal expansion.

The zero point moves in an undefined manner.

Too much clearance

Positioning via a cylindrical or conical clearance fit.
Example of stud/socket clearance fit:
Ø 35 h5/H5 = 22 µm
