Bore Scanner Tests Surface Structure, Roughness

Jenoptik introduces its Hommel-Etamic Toposcan for measuring the surface of cylinder bores larger than 60 mm in diameter. The scanner is capable of automatically measuring the size of porosity and blow holes, stroke reversal radius, laser pocket structures, roughness of bore walls, torn and folded metal, and cross-hatch angles. It is suitable both for R&D tasks and for the production line.

A 60-mm measuring probe performs optical testing of bore surface structure characteristics and tactile measurement of surface roughness. It offers optical zoom from 30 to 210 times for inspecting fine structures. Optical inspection and roughness measurement at any position can complete evaluation of the cylinder surface. The basic system enables optical testing, and an advanced model can complete additional tactile roughness measurement. Both include a mobile workstation for easy transportation.

The numerical and graphical output of the roughness parameters and profiles can be combined with the image evaluations in one report to provide compact and informative documentation.

The scanner’s lightweight and ergonomic design eases mobile use. The centering plate is adapted to the diameter of the cylinder bore. Manual radial probe positioning is performed by the operator.

The product includes a lighting unit and a roughness probe for determining all selected surface characteristics. Motorized axial positioning, zoom, focus setting and lighting regulation are carried out using the computer. The roughness standard allows for immediate verification of the measuring system. Cylinder bore surface is instantly displayed on the computer screen.

The Topowin software offers a standardized interface for optical surface inspection and roughness measurement.
