As a consequence, Hermes was the first European abrasives factory to be successfully audited on the basis of voluntary certification. The “Environmental Protection” department at Hermes painstakingly ensures that every business process makes sparing use of natural resources. As a consequence, protection of the environment is a cornerstone of Hermes’ business policy and a key constituent of our corporate responsibility. ound by tradition on the one hand, but pioneering developer of innovative products on the other, Hermes places enormous emphasis on the production of high-quality, high-performance abrasives in accordance with the state of the art. The TÜV NORD CERT certification company awarded the Hermes Group the quality seal demonstrating compliance with the requirements of DIN EN ISO 9001 to enable this high standard of quality to be continued and extended in the future.

For these applications in particular, the flexible characteristics of the abrasive in belt-grinding, combined with an elastic backing element, result in significant benefits compared to grinding with bonded abrasives. Such methods include hand-held belt grinding of turbine blades on the so-called belt-grinding wheel stand, semi-automatic belt-grinding to copy spanners and fully-automatic CNC belt-grinding using a 6-axis elbow-armed robot to shape implants made of titanium alloys or sanitary fittings made of brass. Hermes provides solutions with abrasives of varying flexibility with type structures perfectly adapted to suit the materials for machining.
