Surface measuring machine
HOMMEL-ETAMIC
Surface inspection system for cylinder bores
The topometer is the ideal inspection system for fast, precise, and reliable testing of fi nely machined (e.g. honed) surfaces of cylinder bores during development, tests and production. Optical testing of surface structure characteristics and tactile testing of surface roughness is carried out using a compact measuring probe.
Measurement and assessment of surface features such as
• Crosshatch-angles
• Dimension of surface structure
• Area of blowholes
• Stroke reversal radius
• Laser honing structures
• Roughness
of cylinder bores in R&D and production areas
High flexibility
The topometer is available in two versions: The basic model for pure optical testing, and the advanced version, which includes roughness measurement. It is possible to upgrade the basic model with the functions from the advanced version. The probes have a working length of 150 mm or 210 mm, and can be used in bores from 60 mm cylinder diameter. Different bore diameters can be modifi ed by simply replacing adapter collars. These are also used for positioning and centering the probe.
Easy handling
The complete system is controlled centrally via a PC that is equipped with additional circuit boards for digital image processing and roughness measurements.
The TOPOWIN software is clearly structured and guides the user through the measuring program step-by-step.
