Sorting into three tolerance bands: Horizontal Visigauge with Feedback Bin
A client had a 13 µm critical OD tolerance and had to sort every part into 4 µm, 4 µm and 5 µm bands; manual sorting was mixing OK and NOK parts.

The problem
- Critical outer-diameter tolerance of 13 µm.
- Every part to be sorted into three bands: 4 µm, 4 µm and 5 µm.
- Manual inspection could not keep up and depended on the operator.
- OK and NOK parts were being misplaced, so batches had to be rechecked.
The machine
- Horizontal Visigauge with the Feedback Bin: measurement and sorting in one machine.
- 1 µm repeatability on the critical OD check.
- Automatic sorting of each part into its band.
The result
- Every part measured, sorted and recorded without manual handling.
- Client's report: no mix-ups since installation.

A precision-parts client had to hold outer diameter within 6 µm; two orientations per part and separate OD and ID reports were slowing the line.
