Surface Roughness Comparators

Surface comparison plates / roughness comparison samples

Comparison plates is now a common term, but we also use the terms surface comparison samples (DIN 4769), comparison standards or standard set.

The comparison plates / roughness comparison samples are used to assess and test the surface quality in production and inspection. With the tactile and visual comparison the surfaces of workpieces that have been produced using the same manufacturing process are compared with the corresponding surface comparison sample.

The SMT-MESSZEUGE® Rugotest surface comparison plates (article no. 920.000) are available as an overview table with the six most important manufacturing processes in metal-cutting production in a set or as individual roughness comparison samples (article no. 921.001 to 921.018). With 30 surface comparison pieces / roughness samples, the set covers the 6 most important manufacturing processes in metal-cutting production. Included here are flat lapping, flat grinding, reaming, horizontal milling, face milling and longitudinal turning. This roughness sample set is ideal for vocational schools and training workshops to learn and determine surface quality and surface roughness through tactile and visual comparison.

The galvanoplastic manufacturing process ensures the high accuracy and unconditional uniformity of the surface roughness of all panels with item no. 920.000 and 921.001 to 921.018. It is important to note here that each of the 30 surface comparison pieces / roughness patterns from the overview panel set (SMT-MESSZEUGE item no. 920.000) is identical to the corresponding surface patterns from the respective individual comparison standards with SMT-MESSZEUGE item no. 921.001 to 921.018, so that both comparison patterns can be used side by side. This in turn also makes it possible to procure individual production processes with the required reference sample at a later date. 

These reference samples for roughness and many others are of course also available as individual reference plates with the desired production process of surface grinding, cylindrical grinding, face turning, cylindrical turning, end milling, horizontal peripheral milling, shaping + planing, linsihing belt-sanding, hand filing, polishing, honing, vertical grinding, casting, spark erosion EDM, flat lapping, cylindrical lapping + super finishing, reaming + drilling, grit blasting + shot blasting.

The respective manufacturing process is indicated on each set of surface pieces. All surface comparison samples are labelled with the corresponding "average roughness value Ra" and the "average roughness depth Rz" in µm as well as the ISO roughness class (N code).

label, whilst the roughness values of each patch are given on
the middle label in terms of the parameters Ra and Rz-DIN,
together with N-classes, in both microinches and micrometers.
The actual values of the patches are within the tolerances allowed
by the standards BS 2634, ISO 2632, and ANSI B 46.1.
The parameters and procedures for measuring them are defined
n BS 1134 and BS ISO 4287. Please note that the terms "CLA"
and "AA" mean exactly the same thing as "Ra".
