| µsurf cylinder - measurement of cylinder running surfaces
|
|
The µsurf cylinder enters the cylinder bore using an angled optical system. Bore diameters from 70 mm, as well as and a penetration depth of up to 165 mm can be managed without difficulty. The motorized system is steered using a joystick. Any given position within the cylinder bore can be reached very quickly. For performing repeat measurements and series investigations, automating measurement profiles are stored in the database.
Roughness is evaluated according to DIN EN ISO, whereby more than 30 characteristic values are available. Those 3D structural features which are tribologically relevant are computed and clearly presented. The ?soft analysis software allows for comprehensive evaluations, analyses and reporting.
The precision of the measurement system is in the nanometer range. Traceability to national standards is guaranteed. For instance, investigations carried out at the NIST (USA) yielded a 99% correlation with tactile roughness measurements. In contrast to a scanning electron microscope (SEM) the ?surf cylinder also provides absolute measurement values of structural depth. No sample preparation of any kind is needed. ?surf cylinder?? contactless measurement capabilities are equally suited to production situations, as well as for continuous use in QA and testing environments. |
