Grinding belongs among those cutting procedures in which the tool has many cutting edges that are irregular in shape and act as turning knives during grinding. Grinding is performed at very high speeds, up to 125 m/s. It can be divided into coarse, fine, honing and finishing. The following effects can be achieved: • High material removal rates • Very smooth surfaces • High dimensional accuracy • Ability to work very hard materials SWATYCOMET was founded in 2010 and represents the merger of two reputed companies with their own individual rich traditions, i.e. over 130 years of SWATY of...

ABRASIVE GRAIN SIZE Abrasive grain size complies with international standards and requirements. It is designated with numbers according to the FEPA standard. The number indicates the number of holes per inch length (25.4 mm) in a wire sieve that permits the grain to pass through. Macro grains have a granulation up to 200, and micro grains have a granulation of over 240. Coarse grain is intended for coarse grinding, in which large material removal rates are required, while finer grain is intended for achieving smooth surfaces and for small material removal rates.
