Positioning for measuring turned parts without adjustment

Installation for measuring turned parts

To avoid positioning the part on two blades, it is placed between two flat transparent supports that create a certain angle between them. The part can thus naturally "lean" thanks to gravity. The optical path of the light emitted by the source is modified so that the image seen by the camera is no longer from above but from the side, thus the measured dimensions correspond to reality. It is therefore no longer necessary to precisely position the part along its axis of rotation, which eliminates the planing operation.

The qmtvline is patented (CH716489)

More than 35 years of history

A history marked by innovation. qmt developed the Multimicro in 1991, which received an award from Crédit Suisse (motorized image analyzer with automatic microhardness measurement). In 2015, qmt won the Geneva Canton Innovation Award.

Our history

Measurement of turned parts

All the characteristics measured in a few seconds

A control program is created to define the different dimensions to be controlled (diameters, lengths, angles, gauge plan, etc.).

Lay the part down and within seconds all features will be measured.

The use of the qmtvline installation allows the realization of the control without any adjustment, even during a change of article.

A perfect combination

Fast and accurate measurement with the qmtprojector-100

The qmtprojector-100 is a universally accessible testing device, specifically designed for production control in the microtechnology and watchmaking sectors. It allows for high-precision measurement of the dimensional characteristics of static parts in the open field. The qmtvline allows for the measurement of turned parts without adjustment or alignment. The measurement is therefore very fast and accurate. Custom functions can be developed within the qmtf4u customization program.

The strengths of the qmtprojector-100

Versatility: flat parts without laying, turned parts with the qmtvline , beats with the qmtwheeltest-vision technology
High precision: qmtjust to guarantee metrological performance
Great ease of use even for complex measurements
No planing: reliable and very fast measurement of turned parts with the qmtvline fixture
qmtsixsigma option for APC (Automated Process Control)

qmtvline compatibility

The qmvline is compatible with the majority of optical equipment

It is possible to take advantage of the benefits of qmtvline on the majority of optical equipment.

qmt has tested and validated the use of qmtvline on Fox, Keyence IM & LM and Marcel Aubert.

Do not hesitate to contact us to assess compatibility with your optical equipment.

Measuring threads

A software function for measuring threads

A specific measurement function has been developed to allow all measurements to be carried out without any programming. After removing the part, the measurements are automatically carried out, they are precise to the micron and repeatable as specified in the NIHS standard
