Metallographic Polishing

Metal polishing and polishing of other materials have to remove the deformations introduced during grinding and provide a highly reflective finish, so the samples can be examined on the microscope. Our polishing consumables are developed and optimised to provide the best result in the shortest time at an affordable cost.

The purpose of metallographic polishing is to assure that the true structure of the sample is made visible with a surface finish that will not disturb the examination in question. This is typically done in 2 or 3 steps  using suitable polishing cloths and gradually finer abrasives. These are selected depending on whether it is metal polishing or polishing of another material type.

Metallographic Polishing Cloths

We have a large selection of polishing cloths that are used according to sample material and preparation step – e.g. metal polishing. All of our polishing cloths are available in both a self-adhesive (Aka-) and a magnetic (Mag-) version and can be supplied in all standard diameters. The Aka-cloths can also be produced in custom-made sizes up to 1250 mm in diameter. The fabrics used for our polishing cloths are carefully selected to provide the best possible polishing results for the polishing step and material they are recommended for. They are laminated together with a water, ethanol and oil resistant polymer barrier layer, that protects the cloth texture from wear and assures that the diamonds are kept in good contact with the sample surface giving a fast preparation at a minimum cost.

Advantages of Akasel Polishing Cloths

Our polishing cloths are designed to deliver exceptional results for a wide range of applications. The variety of cloths we offer ensures that you can find the perfect match for your specific needs, whether working with soft metals or hard materials. Each cloth is developed to enhance its performance, providing excellent resilience and longevity.

Incorporating a water, ethanol, and oil-resistant polymer barrier, our cloths maintain their integrity under various conditions, ensuring consistent performance and minimal wear. This results in faster preparation times and superior surface finishes, making your processes more efficient and cost-effective.
Our commitment to quality and innovation ensures that Akasel metallographic polishing cloths provide exceptional planeness and edge retention, which are critical for the sample analysis. Our versatile polishing cloths are designed to handle a wide range of applications, delivering reliable and reproducible results consistently.

Diamond Products

Our polishing consumables include a wide range of diamond products of the highest imaginable quality ensuring the best possible metallographic polishing result every time. We use both polycrystalline and monocrystalline diamonds in very narrow graduations and high concentrations, yet at an affordable price. Our diamond products include 2-in-1 diamond suspensions, a carefully adjusted mixture of suspension and lubricant, diamond suspensions to be used with lubricants, diamond sticks, diamond sprays and diamond pastes. Our diamond products are available with poly- or monocrystalline diamonds and in grain sizes 15-0.05 µm.

Oxide Polishing Suspensions

For the final polishing step, where the very last deformations have to be removed, sub-micron sized oxide polishing suspensions are used. For general applications alumina suspension is used, and for the more demanding applications silica suspensions are the best choice.

Lubricants

All diamond products, other than our 2-in-1 suspensions, require the addition of a lubricant during preparation. The lubricant serves as lubricating and cooling liquid. Depending on the material and the preparation step you either need a thin lubricant with high cooling efficiency for high material removal or a thicker lubricant that is designed to avoid scratches and deformations, resulting in a scratch-free final polishing of soft materials.  We probably offer the broadest range of lubricants, enabling you to choose the product best suited for your metallographic polishing step(s).

All of our polishing consumables are available for metal polishing and polishing of other materials.

Efficient Polishing with our Aka-Brief Preparation Methods

To streamline the polishing process and ensure optimal results, we provide detailed guidelines with our Aka-Brief preparation methods. Aka-Briefs offer step-by-step instructions tailored to various materials and polishing requirements, helping you achieve consistent and reliable results efficiently. By following the Aka-Brief recommendations, you can enhance preparation speed and surface quality, making your metallographic polishing process more effective.
