INVOLUTE PROFILE TESTER ES4300
Measuring and charting of the tooth profile (true or modified involute), i.e. computing and recording the deviation of the actual measured profile from the theoretical involute.
lnspection of gears of size and weight for which there is no gear measuring machine available.
lnspection of tooth profile on the gear production machine, i.e. without breaking down the set-up. Based on the measured profile characteristics, corrections to machine settings can be made directly during the machining process.
Avoidance of machine standstill, which occurs when a workpiece has to be removed, set up on a gear measuring machine, and again set up on the production machine. Fast set-up, simple Operation and accurate measurement thanks to the stable construction, the in-built processing of the measuring data and by the tip-up and rotatable display with touch-screen.
The portable pitch measuring instrument is a universal device. The only prerequisite for its use is a stagnant gearwheel, where the workpiece to be measured can be accommodated.
The apparatus is therefore employed directly on the machine tool or as a supplementary device on measuring centres. The operator is guided through the setting up and the measurement; the tuition time is minimal, the measurements are performed automatically. The records are printed out via wireless printer or via Memory stick.
The measurements can be stored on an external PC in the form of an Adobe Acrobat PDF file.

Basics In the first phase of the measuring cycle, the levelled Measuring Unit orients itself automatically relative to the gear. This takes place via the ball rests, the compound slide and the probe.
Referring to the input gear data and setting data, the ES-4300 then computes the coordinates of the theoretical involutes. In the second phase, the actual measuring phase, the probe is moved automatically along the tooth profile, and the coordinates of the tooth flanks are determined.
The profile charts are derived from the comparison between the coordinates of th tooth flanks and those of the theoretical involute.
