§≡≡≡≡   Functions   ≡≡≡≡


1. High accuracy(precision Heidenhain glass-scale, precision guide rail)

2. High reliability(100,000 repetitive experiments)

3. High speed: fast measurement and stable indication value

4. Easy to calibrate

5. Measuring spindle which is guided by the linear rolling bearing can bear big radial force in travel, at the same time its` micro friction is very small.

6. Wide application: Manual measurement or positioning of equipments. Fast, accurate, reliable measurement for length, separation distance, height, thickness or linear displacement.
