GRAIN SIZES
ACCORDING TO THE RIEGGER STANDARD
 
     
 

In the RIEGGER standard, the individual grain size classes (grain size dispersion) are graduated from coarse to fine so that the diamond grain size optimal for the work sequence at hand is always available. One of these grain sizes is always the most economical choice and just barely capable of achieving the required surface finish.

If polishing carriers made of the same material are used in different machining steps, a roughly 5:1 leap in grain size is possible from one process step to the next.

Example: Process step A with 60µm, B with 15µm and C with 3µm.

When changing from a hard polishing carrier material for premachining (e.g. steel) to a soft polishing carrier material for fine polishing (e.g. felt) the leap in grain size is limited to 3:1.

Example: Process step A (steel) with15µm -> Process step B (felt cloth) with 6µm.
