Rigid Grinding - Fine Grinding

Replace multiple paper steps with a single rigid disc. Our solutions ensure exceptional flatness and edge retention for harder materials.

The purpose of fine grinding metals and other materials is to remove deformation and possible thermal damage introduced during sectioning, preparing the samples for polishing. Our rigid grinding discs, including the Aka-Allegran series and Aka-Largan 9, are the optimal choice for this critical step. Designed for materials harder than 150 HV, they ensure exceptional planeness and edge retention, significantly enhancing the efficiency and quality of your sample preparation.

With a unique surface design mounted on a thin, rigid steel plate, these grinding discs guarantee optimal flatness and offer a very long lifetime. They provide continuously high material removal rates, making your grinding process more efficient and cost-effective. One disc can replace multiple steps of traditional grinding papers, simplifying your workflow.

    Aka-Allegran 3

Aka-Allegran, available in 4 different versions, is recommended for fine grinding of metals and other materials that are harder than 150 HV.

  • Aka-Allegran 9 provides perfect planeness and edge retention. It is the hardest of our grinding discs and recommended for materials harder than 450 HV. It can replace grinding papers P320-P1200. Aka-Allegran 9 should be used with diamond suspension 15 – 3 µm.
  • Aka-Allegran 6 is the most universal disc in the range. It is the correct choice when an optimal balance between material removal and fine surface finish is required. Aka-Allegran 6 provides fast fine grinding of most materials with a hardness of above 150 HV. It is recommended to be used with 9 – 3 µm diamonds. It will replace the traditional grinding steps from P320 – P1200 with one single step.
  • Aka-Allegran 3 provides short preparation times, completely plane samples and retains soft phases (e.g. soft inclusions in steel). It is a medium hard disc that is recommended for materials harder than 150 HV. It replaces grinding papers in grit sizes P320-P1200. This grinding disc should be used with diamond suspension 9 – 3 µm.
