The comparison and analysis of cust

The comparison and analysis of customer detection data and OMNI detection data are as follows:1. The outer diameter of the wheel is larger. Due to the material characteristics, the outer diameter will increase with the increase of temperature.2. For Runout Ng, we have 100% of the Runout detection confirmation, preliminary determination of customer measurement method problems; 3.It is confirmed that the measurement of the stiffness of 2.5 mm and 3 mm under the client test are within the specification according to the experimental verification, and the deviation will not lead to the over-tolerance, preliminary suspicion of client-side measurement equipment and measurement method problems;
