Grinding

The purpose of metal grinding and grinding of other materials is to remove the deformation and possible thermal damage introduced during sectioning and to prepare the samples for polishing.

When your samples have a rough surface or are clamped in a sample holder, you need a plane grinding step first. When preparing individual samples or samples by hand, you can go directly to fine grinding. The purpose of grinding is to reduce deformation and other types of damage introduced from cutting to a level that allows the sample to be polished. Fine grinding can be done in several steps using gradually finer grit sizes or in a single step on a modern rigid grinding disc.

Grinding Methods

Our diamond grinding discs are the state-of-the-art alternative to grinding papers. They provide a much longer lifetime, a more uniform material removal and outstanding flatness. The Aka-Piatto series of grinding discs outperforms grinding papers, especially with harder materials, where grinding papers wear very fast. The result is lower cost per sample along with a much better finish.

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 the hardness and ductility of your material. When diamond suspension or diamond 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 types of materials. Our Rhaco Grit is either based on Al2O3 in the coarser grit sizes for high removal and long lifetime when grinding harder materials, or on SiC in the finer grit sizes for grinding of softer, more ductile materials.

Grinding Stones are used for plane grinding on dedicated high-speed machines for fast removal of material and the preparation of many samples.
