We normally differentiate between Cloths and Ridgid discs. The former being specialised textiles laminated to make either a self-adhesive cloth or a magnetic cloth.

These are by far the most common ways of polishing. A cloth has quite a bit of room for accepting abrasives and lubricants which in turn makes it easy to use, not needed a precise and contant flow of suspension and lubricant to perform well. The roomy texture is on the other hand the reason for the typical edge rounding associated to cloths. This is why the latest additions to polishing has been the ridgid discs.

Rigid Disc
These are polymer composite discs coated onto a steel disc for magnetic adaptation. The composite surface is generally harder than textile and will therefore give excellent edge retention. But the composite surface also allows a higher degree of contact between abrasive and sample surface thus allowing for higher abrasion resulting in quick preparation. The latest addition to this line is Allegran-3 and Allegran-1. The combination of high removal and fine surface finish often allows easy 3 step methods.

Magnetic adaptation
Magnetic discs are by far the easiest way of holding consuambles on the disc. Some consumables might not be available in a magnetic form, thus an adapter is necessary.

Diamond Products

Reproducible preparation

Many factors are involved when seeking short preparation times as well as reproducibility.

Uniform diamonds with uniform geometry

The decisive factor in achieving uniform particle size distribution is to use uniform, almost cubic-shaped diamonds. A single needle shaped diamond, can ruin a perfect preparation. Therefore, the objective is to minimize the presence of deviating geometry, such as needle-shaped crystals or flakes.

Narrow batch tolerance

Diamonds are graded into very narrow particle size intervals with a very narrow standard tolerance. Variances are minimized from batch to batch, which is evident in the documentation under specifications.

Controlled slurring

Small particles, diamonds included, have a tendency to agglomerate if the slurry process is not conducted correctly. We inspect the product all the way through manufactoring to ensure it meets our specifications.

Narrow particle size distribution

When using super abrasives like diamonds, it is important that particle size distribution has the most narrow deviation as possible. Large particles will be more abrasive and require longer preparation times in the subsequent step, and small particles will not provide the required material-removal rate, thereby prolonging the ongoing preparation step. We therefore use the most stringently graded diamond particles available. Modern sorting technology, combined with electronic and optical quality control, ensures highly reproducible preparation results.

High diamond concentration

All our diamond products have the same concentration regarless of the grain size. Grain sizes 0.1 µm to 3 µm are therefore up to 50 % more concentrated than competing diamond products.

Oxide Suspensions

Akasel manufactures both Silica Oxide and Alumina Oxide suspensions. Both oxide products use our non crystalizing formulation.

Silica suspensions polish by a chemical-mechanical reaction. The sample surface is etched. The resulting layer is removed by the soft silica. The final surface is without deformation.

We have a wide selection of oxide suspensions for final polishing.

  • Colloidal and Fumed 
  • Grain sizes from 0.2 µm to 0.050 µm (200 to 50 nm)
  • Unique system to prevent crystal formation
  • Water-free suspensions

Akasel water-free version of the 0.2 µm fumed Silica is a unique product.

Alumina suspensions for final polishing have a higher removal rates than silica suspensions. It is possible to add etchants to increase removal rates.


Complete range

Our lubricants have an unmatched combination of removal rate and surface finish. We utilize a 2 phase system, with particle size in nano range. This allows for the lubricant to get in between the diamond and the sample, where the actual cutting is taking place.

Water based

Aka-Lube Clear+ with the thinnest lubricating film, used where material removal is most important.

Aka-Lube Green with a thin lubricating film, used where material removal in combination with finish is most important.

Aka-Lube Red has the thickest film and is used for final polishing where the finish is more important.

Aka-Lube Yellow ranges between the two and is used where Lubricant Green is too aggressive, or as a general Lubricant.

Water free

Aka-Lube Clear water free non flammable polymer based version of Aka-Lube Clear+. Very thin lubrication film.

Aka-Lube Blue traditional ethanol based lubricant with very thin lubrication film used for high removal or water-free preparation.

Aka-Lube Blue Concentrate is a non-hazardous concentrate that  is mixed with 99% Ethanol to make your own Aka-Lube Blue directly in you lab.
