- Roundness measurements without measuring
machine?
- No precise bearings?
- Measurement during the production
process?
- Still precise?
Our patented method for the measurement of roundness, diameters and
coaxiality requires a relatively simple arrangement of sensors.
The measuring signals are detected online and evaluated by means
of a complex software package. The results are immediately shown
in a formplot. Once the calibration of the device has been
completed, the diameter can also be determined. And by the way,
you can produce the calibration standards yourself as they do
not need to be very precise. However, it is important to measure
the standard on a measuring machine. These data will then also
be calculated in the software.
It is also possible to
determine the shifting of the rotary axis during the rotation of
the workpiece. This produces a virtual bearing. An additional
sensor immediately measures the runout error.
The reference-free roundness measurement and diameter measurement on
rotating workpices is performed with three or four transducers
which probe the workpiece from different angles. The circular
form errors as well as the superimposed movement of the rotary
axis are evaluated at the same time.
