Better understand fracture, wear and deformation phenomena for both new and used parts.
- Take dimensional measurements (radius, diameter, depth, angle, etc.):
– For complex and three-dimensional parts (precision: ± 3 microns)
– For new or used parts – measurement of dimensions specified on the plan (railway safety components, equipment, etc.)
- Measure shape and position defects: Straightness, flatness, circularity, cylindricity, circular shape, parallelism, perpendicularity, coaxiality, concentricity, etc.
- Measure surface condition, thread dimension, threads or grooves
- 3D measuring machine (Tri-mesures)
- Profile projector (Starett-Sigma)
- Measuring column (Roch)
- Numerous other measuring devices: Micrometers, gauges, roughness testers, etc.
