It is equipped with a pair of Morse No.4 finials, which improves the measuring accuracy of the bench center and increases the support strength to the tested parts. It can measure the radial, end surface and bevel bound of precise parts. The design of the indicator stand is delicate and reasonable, and it can be easily adjusted to all directions. The rigidity of the indicator stand is high, and thus the sensitivity of the testing instrument is improved.

Main technique parameters:

Normal type: The accuracy of the radial rotation is 0.003mm.
The parallelism between the side leading track and the link of the two finials is 0.005mm (A03, B03 type), 0.008mm (A05, B05 type), 0.02mm (A10, B10 type).
The max diameter of the tested part is 250mm.
The max lengths of the tested part are 300mm, 500mm, 1000mm.
