Abstract

The machine has a sensor head which can be displaced in three spatial coordinates. At least one structural element (3,4,6,7,8) made of ceramic material with an expansion coefficient of 3x10->6>/K or less is directly or indirectly mounted on the sensor head and represents one spatial coordinate (XYZ). The structural elements may comprise supports (3,4), crosspiece (6), slider (7) and/or spindle sleeve (8). The ceramic material may be aluminum oxide ceramic.
