Which polishing paste is most suitable for your application?

The surfaces of tools often require a certain roughness, from technically smooth to a deep high gloss. As is often the case, the right tools are already half the battle here.

What types of diamond paste are there?

Each Kemet diamond paste is a mixture of diamond powder with a specific grade and concentration in a chemical carrier. The pastes contain mono or polycrystalline diamond, carefully sorted by grain size by a specific vision system. Because all diamond grains in the paste are exactly the same size, the Kemet diamond pastes guarantee constant performance. The chemical carriers are formulated specifically for particular applications. This results in a complete range of products, tailored to various materials and application methods.

Manual polishing

When you polish manually, the speed of the polishing tool is relatively low. However, you want a high cutting force for a quick result. The water-based KD diamond paste is suitable for all metals thanks to the availability of different concentrations of diamond. The 90 µm KD paste guarantees fast stock removal. In several steps you can work finer and finer to a super finish with the 0.1 µm paste.

Type KD Diamond Paste

  • Universal diamond paste / diamond compound for stock removal and superfine surface finish.
  • This diamond compound is soluble in both oil and water.
  • Diamond compound recommended for Toolroom and Precision Engineering applications.

Each micron size is available in a range of concentrations:- (C1 lowest concentration; C4 highest concentration)

Machine polishing of moulds

Do you work with electric or compressed air powered hand motors or even ultrasonic? Then the speed is much higher and you develop much more heat. The L oil-based diamond paste has a very high heat resistance. As a result, the product can be used directly on injection moulds. The paste is slightly sticky so that it stays on the polishing tool well. This way you can work extremely accurately with a minimal amount of diamond paste. Type L is highly concentrated and stays perfectly in suspension if you add oil for possible dilution.

Type L diamond paste

  • Oil Soluble diamond compound / paste specially developed for use on hard materials such as Tungsten Carbide, Hardened Steels and Ceramics.
  • High thermal stability of the carrier ensures that Kemet Diamond Compound resists frictional heat, remains stable and keeps its suspension properties under operating conditions.
  • Diamond compound recommended for Toolroom and General Production applications.

Each micron size is available in a range of concentrations:- (C1 lowest concentration; C4 highest concentration)

How to use Diamond Paste

Ensure that the substrate you wish to polish is clean and free from any dirt, debris, or previous coatings. Thoroughly clean the surface using a mild detergent or solvent and rinse it with clean water. Dry the substrate completely before moving on to the next step.

  1. Diamond paste is highly concentrated, so a little goes a long way. Begin by applying a small amount of diamond paste onto the lapping plate or flat surface.
  2. Spread the diamond paste evenly across the lapping plate or flat surface. Ensure that the paste is distributed uniformly without any clumps or gaps.
  3. The amount of diamond paste required depends on the size of the substrate and the desired level of abrasiveness. Generally, a small pea-sized amount is sufficient for most applications.
  4. Place the substrate onto the lapping plate or flat surface, ensuring proper contact between the diamond paste and the substrate.
  5. Depending on the hardness of the substrate, apply gentle and even pressure while moving the substrate in a circular, figure-eight, or back-and-forth remove the red ones.motion. Take care not to apply excessive pressure, as this may lead to uneven results or damage the substrate.
  6. Maintain a consistent pressure and motion throughout the polishing process. This helps ensure uniform removal of material and even distribution of the diamond particles.
  7. Pause periodically during the polishing process to inspect the substrate's surface. Rotate the part by 90 degrees to maintain parallelism Check for any visible scratches, imperfections, or desired levels of shine.
  8. After each polishing stage, clean the substrate thoroughly to remove any residue or excess diamond paste. Inspect the surface for any remaining imperfections or scratches before proceeding to the next step.

After reaching the desired level of polishing, ensure to thoroughly clean the substrate once more, effectively eliminating any traces of diamond paste residue. Utilising an ultrasonic cleaner is highly recommended for this final cleaning step.
