QMTWheeltest-Vision

Control of rotating watch mobiles
QMTWheeltest-Vision
Beat measurement equipment

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 part measured is compliant or non-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 the QMTWheeltest-Vision
  • High-precision dynamic beat measurement
  • Integrated binocular for easy component handling
  • Five interchangeable Wheeltest drives ensure rotational speed for optimal metrological performance
  • Intuitive software displaying results graphically with location (ISO GPS) and sharing functions

QMTWheeltest-Vision technologies
Non-contact optical measurement coupled with VOH Wheeltest drive systems

The optical assembly is digital, it allows the acquisition of the image stream with high resolution and high speed. The lens is telecentric to ensure optimal optical precision.

Telecentric lens

This optical technology allows the removal of optical defects from
magnification, perspective errors and distortion.

High resolution digital camera

1.3 MPixels camera (1'300 x 1'000 pixels) at 30 images / second

LED transmitted light

This lighting only allows you to view and measure the contour of the room.

Component training with the five VOH wheeltests

Rotation of the part for dynamic measurement. With the 5 settings, all the components can be controlled: moving parts, boards, gears, ...

QMTWheeltest-Vision applications
The measure of beats and sharings
Balance wheels, escape wheels, timer mobiles, chrono wheel, ...

The QMTWheeltest-Vision with Wheeltest 1, 3 or 5 settings allows the component to be rotated at a constant speed. The optical system can thus make the dynamic measurement to calculate the axial and radial beats as well as any splits. The Wheeltest 5 offers clearance at the ends of the pivots in order to be able to carry out measurements on these areas.

Boards

The QMTWheeltest-Vision with Wheeltest 2 or 4 positions allows the board to be rotated at a constant speed. The optical system can thus make the dynamic measurement to calculate the axial and radial beats.

GPS measurements (location)

The software allows the measurement of toleranced components in GPS.

QMTWheeltest-Vision software
A software dedicated to measuring beats and sharing

The software has been completely developed by Qualimatest. It has an intuitive user interface and measures all characteristics automatically.

The adaptation of a product according to your specific need
Personalization of a product

Qualimatest products can be customized both in terms of equipment and software. The first level of software customization is the addition of additional functions ( Complete list of functions ) or the development of a personalized function. It is also possible to personalize the equipment, for example by modifying the field of vision or by adding incident lighting.

OEM program

On the basis of Qualimatest products, it is proposed to produce a labeled product on behalf of our customers who may be private or marketed by themselves.

“More than 100 systems are produced each year for a large number of customers”
