Reasons to choose the QMTProjector-100

Robust in design, this device is equipped with an integrated computer. It benefits from the QMTMesure-Base software for high precision dimensional measurement (without any programming). High precision and ease of use are the two strengths that the customer has retained.

Although QMTMesure-Base offers, as standard, a large number of classic functions (length, diameter, etc.) and others with high added value (GPS function, threading, etc.), the customer wanted to take advantage of the program. F4U offered by Qualimatest. Thus, a new function specific to its measurement requirements.

Metrological performance

Before integrating this equipment into production, the Quality department of this customer decided to launch a repeatability (R&R test) and accuracy campaign. QMTProjector exceeded customer expectations (R&R study according to MSA):

Diameter of the central hole with IT of 6µm: R&R = 5% and Cmc = 19.8
Concentricity with IT of 20µm: R&R = 15% and Cmc = 6.4

Measurement against DXF

In addition to these special characteristics, QMTProjector-100 also measures all the parameters associated with watch wheels (number of teeth, flapping, etc.) as well as the measurement of the deviation from the DXF files of the parts.

Conclusion

Very intuitive and very fast, this new equipment was immediately accepted by the tailors, it has become today their favorite means of control.
