Diamond Grinding Discs

Available in grit sizes P80-P4000 (250 µm – 3 µm)

Our diamond grinding discs Aka-Piatto and Aka-Piatto+ are the optimal choice for plane and fine grinding including ultrafine grinding of all types of materials. Unlike other diamond grinding discs on the market, they have a unique, wear compensating surface design that provides a very long lifetime and continuously high material removal.

Furthermore, due to being on a thin, rigid steel plate, optimum planeness and edge retention are guaranteed. One Aka-Piatto can replace 200-300 pieces of regular grinding paper, making it very cost-effective. Aka-Piatto and Aka-Piatto+ are colour-coded to facilitate identification of the different diamond grinding discs.

Preparation of Metals with Diamond Grinding Discs

Akasel’s diamond grinding discs are engineered to deliver exceptional results in your sample preparation, for example when grinding metals. They offer unmatched material removal, planeness and durability and precision for both plane and fine grinding.

If you are experiencing decreasing or lower removal rates, use our Dressing Stick, that can be used to dress Aka-Piatto and Aka-Piatto+, to maintain optimal performance. When grinding metals with your diamond grinding discs, it is recommended to dress Aka-Piatto/Aka-Piatto+ occasionally to ensure continuously high material removal. How often depends on the type of metal and hardness of it.

Akasel diamond grinding discs are available in two different versions as Aka-Piatto and Aka-Piatto+. Aka-Piatto+ has the same features as Aka-Piatto, but twice the diamond concentration. This makes Aka-Piatto+ the perfect choice for the preparation of brittle materials like ceramics, cermets (e.g. CMC; Ceramic Matrix Composites) and sintered carbides. The very high diamond concentration makes the abrasion less aggressive due to a lower specific pressure and at the same time greatly increases the lifetime of Aka-Piatto+.

With Aka-Piatto and Aka-Piatto+ diamond grinding discs you obtain continuously high material removal, optimum planeness and great edge retention in your plane and fine grinding steps.

Diamond Grinding Discs for Brittle Samples

Akasel diamond grinding discs can be used for both plane grinding and fine grinding. For plane grinding we recommend Aka-Piatto/Aka-Piatto+ #80, Aka-Piatto/Aka-Piatto+ #120 and Aka-Piatto/Aka-Piatto+ #220. For fine grinding we recommend Aka-Piatto/Aka-Piatto+ #600, Aka-Piatto/Aka-Piatto+ #1200, Aka-Piatto #2400 and Aka-Piatto #4000.

As mentioned above, Akasel diamond grinding discs are available in two different versions as Aka-Piatto and Aka-Piatto+. Aka-Piatto can be used for plane and fine grinding of most materials and metals with a hardness of 150 HV or harder.

Aka-Piatto+ with identical features to Aka-Piatto, but twice the diamond concentration, is the optimal choice for plane and fine grinding of brittle materials like ceramics, cermets (e.g. CMC; Ceramic Matrix Composites) and sintered carbides. The very high diamond concentration makes the abrasion less aggressive due to a lower specific pressure which is ideal for the preparation of this type of materials.

Whenever possible, we recommend that you use a diamond grinding disc for your grinding step(s), since it provides the best removal rate, planeness and edge retention compared to regular grinding paper. It is also the most economic choice due to the long lifetime of an Aka-Piatto/Aka-Piatto+ diamond grinding disc.For the preparation of soft materials you should use grinding paper for your plane and fine grinding steps to obtain the best preparation result.
