Alumina surface plates are manufactured in 2 accuracy grades (00 and 000). All plates are  tested in a temperature  (20°C) and humidity controlled environment. All Microplan® plates are supplied with a  Test Report , in which error map and installation instructions are reported.  Calibration Certificate available on request*.   The table shows standard sizes, weights, article codes and the absolute flatness tolerances (in micrometers). Microplan® can supply  plates with different sizes according to customer needs and drawings, with holes, threaded inserts, guide or clamping T-slots, clearing grooves and with rubber feet (for the smaller sizes).

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.
