QMTWheeltest-Vision

Control of rotating watchmobiles
QMTWheeltest-Vision
Equipment for measuring beats

During the measurement, the values are displayed instantly in the graph according to the progress. After several wheel cycles (defined time), the results are displayed and indicate whether the measured part is compliant or non-compliant (OK / KO). Batch management, report editing and interfacing with statistical software allow for optimal integration of the equipment into a quality process. The QMTWheeltest-Vision can also be customized with the "Fit For You" program.

The strengths of QMTWheeltest-Vision:
  • Dynamic measurement with high precision beats
  • Built-in binocular for easy component handling
  • Five interchangeable Wheeltest drives ensure rotational speed for optimal metrological performance

The technologies of QMTWheeltest-Vision
Non-contact optical measurement coupled to VOH's Wheeltest drive systems

The optical assembly is digital, it allows the acquisition of the image flow with a high resolution and a high speed. The lens is telecentric to ensure optimum optical accuracy.

Telecentric lens

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

High resolution digital camera

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

LED diascopic lighting

This light only allows you to view and measure the outline of the room.

Training components with VOH's five Wheeltest

Rotation of the workpiece for dynamic measurement. With the 5 positions, all the components can be controlled: mobile, boards, gables, ...

The applications of QMTWheeltest-Vision
Measurement of beats and shifts
Pendulum Mobiles, Mobile Exhaust, Mobile Timer, Chrono Wheel, ...

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

Boards

The QMTWheeltest-Vision with the Wheeltest 2 or 4 positions allows the rotation of the board with 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
Software dedicated to the measurement of beats and sharing

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

Adapting a product according to your specific need
Customizing a product

Qualimatest products can be customized from both an equipment and software point of view. The first level of software customization is the addition of additional functions ( full list of functions ) or the development of a custom function. It is also possible to customize the equipment for example by changing the field of vision or by adding an incident light.

OEM Program

On the basis of Qualimatest products, it is proposed the realization of product labeled on behalf of our customers who can be private or marketed by themselves

"More than 100 systems are produced each year for a large clientele"
