1. The machine adopts a closed frame and a vertical structure. The steel frame with granite base, effective avoids vibration and so ensures the high precision of the instrument.

2. The 4D coordinate measuring system has three linear axes and a rotating axis.

3. The probe of the digital sensor has such advantage as high measuring precision, a large measuring range, small linear errors, convenient stem replacement, force automatic reversing and mis-operation safeguard function.

4. The imported Heidenha positioning grating is adopted for the machine datum position.

5. The advance electronic control system supported by the high precision gratings realizes the full closed-loop movingposition control, also the gear inspection is automatically finished. The efficiency of the measurement is quite high.
