Magnetic Adaptation

Today, magnetic support discs are more and more common because they facilitate the exchange of grinding and polishing discs.
Instead of removing the complete aluminium disc from the grinding/ polishing machine only the preparation surface is exchanged. For that purpose, modern grinding discs like Aka-Piatto and fine grinding discs like Aka-Allegran or Aka-Largan are produced directly on a thin steel disc.
For the best grinding action a stiff support like a steel disc is necessary.
However, not all preparation methods allow the use of these grinding and fine grinding discs, but still require the use of grinding paper. Several solutions are available to use grinding paper on magnetic support discs, but the most efficient and cost effective solution is the Aka-Rhaco.
Aka-Rhaco is a thin steel disc with a soft polymer coating. It will safely hold grinding papers allowing over the edge grinding and substituting expensive PSA or foil backed grinding papers. Aka-Rhaco will last for over 1000 applications and will perform perfectly with our own Rhaco Grit grinding paper. This is equipped with a non-woven paper backing that prevents curling.
Instead of using more expensive magnetic polishing cloths on steel discs, the standard Aka-Cloths can also be placed on Aka-Rhaco without removing the liner. Place the cloth on top of Aka-Rhaco and you have a magnetic cloth. When the cloth is worn, simply pull it off and re-use the Aka-Rhaco.

Aka-Magnet is a polymer-based magnetic foil with PSA backing to convert a standard preparation disc to a magnetic support disc.
As with all polymer-based magnets some maintenance is necessary and eventually the foil will wear. Due to the PSA backing it can then easily be replaced.
