Manufactured with two H-shaped lapped parallel surfaces to ensure stability and lightness. The three levels of tolerances are shown in the table. The parallelism tolerance is equal to the flatness.

Side faces ground (± 20 µm/m). If required, they can be supplied with handles on the heads and wooden case. Microplan® Test Report included. Calibration Certificate available on request*.

Nanoline Alumina high precision instruments

In the field of measuring instruments, the search for new materials with improved mechanical and physical characteristics, led to the use of ceramics for the manufacture of certain instruments. The Alumina (Al2O3) produced by the Microplan® Group has technical characteristics suitable for metrology, such as dimensional stability, hardness, low expansion coefficient and an excellent modulus of elasticity. The tools ofNanoline Aluminaserie are an alternative, cost-effective, compared to the same products in silicon carbide Si-sic, despite having very similar characteristics.
