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.

The strengths of qmtwheeltest-vision
  • High-accuracy dynamic measurements of beats and splits
  • Ease of use with binocular to position component and intuitive software
  • Five training devices to measure all types of components
  • Two measurement modes for laboratory and production

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

With the telecentric lens, the high resolution camera

qmtwheeltest-vision software

Dedicated software for measuring beats and splits for optimal intuitiveness

Configurable measurement export

A configurable export module allows the creation of a personalized configuration without having to make a new version of the software

VOH wheeltest installation
