Manual polishing

When performing manual polishing, the speed at which the polishing tool operates is relatively low. However, if you desire quick and efficient results, it is crucial to have a high cutting force. This is where the water-based KD diamond paste comes into play, as it is specifically designed to meet these requirements for various metals. The KD paste offers different concentrations of diamond, making it suitable for all types of metal polishing tasks. For rapid stock removal, the 90 µm KD paste is highly effective. It ensures that material is removed swiftly and efficiently, allowing you to progress through the polishing process quickly. As you continue with the polishing procedure, you can gradually transition to finer and finer grits of diamond paste. By using the 0.1 µm paste, you can achieve a super smooth and flawless finish.

The type KD Diamond Paste is a versatile diamond compound that serves the purpose of both stock removal and achieving an exceptionally fine surface finish. It has the unique quality of being soluble in both oil and water, providing flexibility in choosing the appropriate medium for your polishing needs. This diamond compound is particularly recommended for applications in Toolroom and Precision Engineering. Its reliable performance and consistent results make it a preferred choice among professionals in these fields. Furthermore, the KD Diamond Paste is available in a range of concentrations for each micron size. This allows you to select the concentration level that best suits your specific polishing requirements. The available concentrations are categorized from C1 (lowest concentration) to C4 (highest concentration), providing you with options to achieve optimal results based on the desired outcome and the characteristics of the material being polished.

How to use Diamond Paste

  1. Prior to polishing, make sure the substrate you intend to polish is clean and free from dirt, debris, or previous coatings. Use a mild detergent or solvent to thoroughly clean the surface, followed by rinsing with clean water. Ensure the substrate is completely dry before proceeding.
  2. Diamond paste is highly concentrated, so a small amount goes a long way. Begin by applying a small quantity of diamond paste onto the lapping plate or flat surface.
  3. Spread the diamond paste evenly across the lapping plate or flat surface, ensuring a uniform distribution without any clumps or gaps.
  4. The amount of diamond paste needed depends on the size of the substrate and the desired level of abrasiveness. Generally, a small pea-sized amount is sufficient for most applications.
  5. Place the substrate onto the lapping plate or flat surface, ensuring proper contact between the diamond paste and the substrate.
  6. Depending on the substrate's hardness, apply gentle and even pressure while moving the substrate in circular, figure-eight, or back-and-forth motions. Avoid applying excessive pressure to prevent uneven results or substrate damage.
  7. Maintain consistent pressure and motion throughout the polishing process to ensure uniform material removal and even distribution of the diamond particles.
  8. Pause periodically during polishing to inspect the substrate's surface. Rotate the substrate by 90 degrees to maintain parallelism and check for any visible scratches, imperfections, or desired levels of shine.
  9. After each polishing stage, thoroughly clean the substrate to remove any residue or excess diamond paste. Inspect the surface for any remaining imperfections or scratches before proceeding to the next step.
  10. Once the desired level of polishing is achieved, ensure thorough cleaning of the substrate to eliminate any traces of diamond paste residue. Using an ultrasonic cleaner is highly recommended for this final cleaning step.
