Profile / Roughness

 

The tactile roughness measurement will remain, for a long time, the standard method in industry. One one side the standardisation is tailored to these instruments and on the other side the current optical methods cannot produce results with satisfactory profile fidelity. The optically measured profiles are more or less disturbed by artefacts. The smoother the surfaces are the more that this is true.

Nevertheless it may make sense to use optical roughness measuring devices in the production line since the tactile roughness measurement is inherently slow. This is especially true for series measurements of the same kind of workpieces. When only roughness parameter values lying within a certain range are required, useful results with suitable optical methods such as stripe projection or speckle contrast can be obtained.

BMT has developed a miniature roughness measuring instrument with excellent technical features. It is at the top of the current possible technical state of the art, e.g. a faster data acquisition rate than so far achieved and a USB interface. This MicroProfiler roughness measuring instrument is exceptionally flexible and lends itself especially for in-line measurements.

The BMT PC controller board can control up to 16 of these units.

 

This results in substantial time and cost savings for our customers.
