What instrument does a coaxial measuring instrument measure coaxiality?
The traditional method of characteristics of cheap thimble at both ends of the axle center hole Yongqian points watch beat.
Three coordinates will be measured and tested 2 cylinder 1 cylinder were measured and then the two ends of the shaft surface respectively to measure a point by point and P1 P2 P1 that the 1 cylindrical structural plane and cylindrical structure to find a circle is the most distal cylindrical section center with A1 P2 and 2 cylinder with the construction of plane plane and then find a circular cylindrical structure to obtain the most distal cylindrical section center A2 with A1 and A2 to construct a line to do a common axis respectively for 1 and 2 of the cylindrical cylindrical coaxial maximum.
