STRAIGHTNESS MEASUREMENT
Definition of straightness measurement
Straightness measurement is performed with two zero points on the
measurement object. An imaginary line running between the zero points
constitutes the reference. As the measurement is performed the result is
given as the proportion between each measurement point and the reference
line.
Requirements
To perform a straightness measurement it is necessary to fulfill the following
requirements
1. The bearing journals to be measured must have identical nominal
diameter.
2. No parts on the fixture can be moved or adjusted during the
measurement.
3. No compensation will be done to small variations in diameters on the
measured bearing journal.
4. Bearing journal roundness and diameter must be checked carefully
for eventual compensation of the measuring result.
Mounting on a flange with magnetic bases. Follow the procedure from step 1.
