1 Internal Measurement Internal Measurement C-1

2 Internal Measurement Internal Measuring and Requirements 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. Advantage of 3-Line contact TESA IMICRO, TRIOMATIC, TRI-O-BOR and ETALON INTALOMETER are self-centring and self-aligning internal measuring instruments that make bore measurement reliable independently of the sensitivity of the user. The 3 measuring bolts spaced 120 apart provide optimum self-centring. Line contact of the 3 measuring bolts allows the instrument to align itself parallel to the contact surfaces.???? A single measuring instrument can replace hundreds of plug gauges Unlike plug gauges that check only one toleranced size, a single instrument can measure many diameters. Depending on the model that is being used, through bores and blind bores as well as short centring shoulders can be measured, reliably. 2-point contact measuring instruments are not self-centring. To make bore measurement easier, auxiliary means will additionally be used. 2-point contact does not allow the instrument to align itself in relation to the bore axis. Establishing form errors Form errors are established by measurements made at several points on the bore. Measuring instruments with 3-line contact determine run-out errors in a triangular way. Measuring instruments with 2-point contact measure medium-size diameters only. They do not allow the user to differentiate diameters measured at various points. D max. D min. D C-2
