The diametral dimension over balls/pins is an important characteristic for gears and splines.
The diametral size is measured with opposed Measuring Inserts. Masters are used to set the nominal size. FRENCO offers a wide range of instruments for the size inspection. Ultimately, your batch size and test frequency defines the suitability of one or the other device, we are happy to help.
From simple manual instruments, through to automatic, process-integrated test equipment, FRENCO offers a custom-made solution. Basically, there are three types.
A pendulum motion of the hand is used to search for the reversal point with the aid of the dial indicator. After previous adjustment with a master, the difference to the nominal dimension is determined.
With manual instruments, the guide profile facilitates the measurement since the search for the reversal point is no longer necessary. The measuring principle is fully automatable.
The face stop ensures that the dimension over balls is always detected parallel to a plane surface. The changeover is easy and the device is suitable for automatic loading and measurement.
