1 Internal MeasurementInternal MeasurementC-1C-2 Internal MeasurementInternal Measuring and RequirementsInternal measuring of bores is more demanding than external Measurement ofworkpieces. Not only the tight tolerances given for the measuring job must berespected, but also the measuring components that have a direct influence onthe uncertainty of Measurement must be designed in such a way that they canenter into the bore to be of 3-Line contactTESA IMICRO, TRIOMATIC, TRI-O-BOR and ETALON INTALOMETER are self-centring and self-aligninginternal measuring instruments that make bore Measurement reliableindependently of the sensitivity of the 3 measuringbolts spaced 120 apart provide opti-mum contact of the 3 measuring bolts allowsthe instrument to align itself parallel to thecontact contactdoes not allow theinstrument to alignitself in relation tothe bore contact measuring instruments arenot self-centring.
