The instrument is fixed with the finial support, and under the coordination of data collecting and processing equipment, it can measure 8 kinds of shape and position differences of the axial parts and disc/sleeve parts, including roundness, column roundness, coaxality, axes, straightness, cable-line straightness, cable-line parallelism, circular bound (radial, end surface, bevel), and radial full bound.
Main technique parameters:
1. The accuracy of the radial rotation is 0.4um.
2. The straightness of the side leading track is 5um (I-type), 6um (II-type), 2um/100mm.
3. The parallelism between the side leading track and the finial axle is 7um (I-type) and 8um (II-type), 3.5um/100mm.
4. The max diameter of the tested part is 250mm.
5. The max length of the tested part is 500mm (I-type) and 800mm (II-type).
