The instrument is mainly used for inspecting the radial bound, circular bound and end surface circular bound of the axial or disk parts. The product is novel and good-looking in design, and its accuracy is high while it is very convenient in use.

Main technique parameters:

1、 The radial circular bound of the Morse No.2 finial 60°cone surface to the Morse cone≤0.005mm;
2、 The parallelism between the finial axle within the scope of 100mm and the leading track (parallel and vertical direction)≤0.004mm;
3、 The max diameter of the tested part is 270mm;
4、 Measuring length　300mm、500mm、1000mm、1500mm.
