The purpose of grinding is to remove the deformation and possible thermal damage introduced during sectioning and to prepare the samples for polishing. Plane grinding, the first step, must produce a uniform finish and get all samples in a sample holder to the same level in a short time. Subsequent fine grinding will remove the deformation from plane grinding and make the samples ready for polishing. This can be done in several steps using gradually finer grit sizes or in a single step on a modern rigid grinding disc.
Diamond Grinding Discs are the state-of-the-art alternative to grinding papers. Especially for harder materials, our Aka-Piatto provides much longer lifetime, uniform material removal and outstanding planeness.
Rigid Grinding Discs are the single step alternative to both grinding papers and diamond grinding discs for fine grinding. Different versions are available to fit your material. When diamond suspension or spray is added during the preparation our Aka-Allegran and Aka-Largan provide optimal fine grinding results.
Grinding Papers are traditionally used for plane and fine grinding of all different materials. Our Rhaco Grit is either based on Al2O3 in the coarser grit sizes for high removal and long lifetime and grinding of harder materials or on SiC in the finer grit sizes for grinding of softer, more ductile materials.
Grinding Stones are used on dedicated high-speed machines for fast removal of material and the preparation of many samples.
