QMTWheeltest-Vision

Control of rotating clock mobiles

QMTWheeltest-Vision

Equipment for measuring beats and splits

During the measurement, the values are displayed instantly in the graph according to the progress. After several wheel cycles (defined duration), the results are displayed and indicate whether the measured part is compliant or not compliant (OK/KO). Batch management, report editing and the interface with statistical software allow optimal integration of the equipment into a quality process. The QMTWheeltest-Vision can also be personalized thanks to the “Fit For You” program.

Measurement for production

A new mode of measurement

The historical measurement mode (advanced mode) is very efficient and well suited to the world of control. We have added a second measurement mode (standard mode) which is much easier to use, it is particularly suitable for the world of production to allow piloting by the workshop

An optical inspection device

qmtwheeltest-vision technologies

The qmtwheeltest-vision is a device developed by qmt to meet the specific needs of measurements in the microtechnical fields and in particular watchmaking.

High-speed full-field measurement

The qmtwheeltest-vision has an optical system that acquires the image of the whole part at high resolution and high speed to allow dynamic measurement.

A built-in binocular

The binoculars integrated into the qmtwheeltest-vision facilitate the removal of the components on the mountings

High measurement accuracy
