Calibration is a grinding process using very thick sandpaper on a steel, massive shaft of 30 cm in diameter.

The use of the calibration process allows to reduce the differences in the material thickness from 1 mm to 0.1 mm, which is extremely important during veneering on the press (avoiding empty spaces under the veneer) and varnishing (avoiding the effect of a curved mirror).
