- Optical measuring instruments
- Precision grinding machine Z-axis
Installation requirements:
Requires mounting surface flatness ≤0.01mm/m and parallelism ≤0.02mm between rails.
Use 4.9-grade mounting screws torqued to 22N·m ±10%. Thermal compensation spacing
(0.5mm/m gap) mandatory for installations exceeding 1m rail length.
