RMP – Roughness Measuring Device

Standards-compliant roughness measurements

The fionec RMP surface roughness measuring station is based on a high-precision fiber-optic measuring system for a standards-compliant evaluation of roughness parameters. Whether installed as a stand-alone system or integrated into existing manufacturing processes, the RMP is perfectly adapted to quickly and contactlessly inspecting rotationally symmetrical precision components.

Its unique miniaturized probes with diameters starting from 50 µm can reach even the smallest cavities and micro-drilled holes (down to diameters of 0.1 mm). Automatic signal optimization means the sensor is able to achieve consistent measurement values for heterogeneous, technical surfaces, too.

Applications

Surface roughness measurements in the precision and ultra-precision manu­facturing sector

Determination of all important roughness parameters, including mean roughness (Ra), mean roughness depth (Rz), maximum roughness depth (Rmax), core roughness depth (Rk).

  • Inspection of technological surfaces and micro-structures following all common production processes

    (turning, milling, honing, polishing, grinding etc.)

  • Measuring flat surfaces and rotationally symmetrical components

    (bearing seats, valves and valve seats, high-precision components for the automotive industry and its suppliers)

  • Measurements in hard-to-access spaces and cavities

Controlling quality, process operation and functionality

  • Evaluation and optimization of product properties

    (for instance of components with tribological or safety-critical functions)

  • Control of tool wear and tear
  • 100-percent testing

DIN EN ISO-compliant evaluation with RMPControl

  • RMPControl: intuitive software with numerous configuration options for setting up pre-defined or custom roughness parameters, filters and measuring procedures
  • Creation of professional measurement and inspection reports in PDF format
