Diamond Grinding Discs
Available in grit sizes P80-P2400 (250 µm - 6 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. We recommend #80, #120 and #220 for plane grinding and #600, #1200 and #2400 for fine grinding.

Diamond Grinding Discs for Brittle Samples
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+.

How do you maintain the diamond grinding discs?
The diamond grinding discs have to be opened with a dressing stick before the first use and dressed once in a while afterwards to ensure a continuously high removal rate. Dressing has to be more frequent with softer, more ductile materials.
What is the wear compensating design about?
Some areas of the preparation disc wear faster than others due to more frequent contact with the samples. This is mostly the centre of the disc and the periphery. In these areas we have increased the density of the abrasive layer to achieve an even wear and thus a much longer lifetime than competitive discs.
What are the advantages of using a diamond grinding disc instead of grinding paper?
Diamond grinding discs, like our Aka-Piatto, are much harder than grinding paper. This results in much more plane samples which again shortens the following preparation steps. And as diamond is used as abrasive, they outperform SiC by far. A single Aka-Piatto can replace at least 200 pieces of grinding paper, making it a much more economic and sustainable alternative.
