Internal measuring of bores is more demanding than external measurement of workpieces. Not only the tight tolerances given for the measuring job must be respected, but also the measuring components that have a direct influence on the uncertainty of measurement must be designed in such a way that they can enter into the bore to be checked.
BENEFIT OF THE 3-LINE CONTACT
TESA IMICRO, TRI-O-BOR, ALESOMETER, ALESOTEST as well as ETALON INTALOMETER are self-centering and self-aligning internal measuring instruments that make bore measurement reliable independently of the sensitivity of the user.
