Description:
Poliflex fine grinding tools are manufactured with high shape accuracy, outstandingly consistent quality and tight dimensional tolerances. They are ideally suited to fine grinding, structuring and preparations for polishing work, and are very frequently used for tool and mould-making applications. Poliflex fine grinding tools with the GHR bond are manufactured with an abrasive grain mixture comprising aluminium oxide and silicon carbide (SiC). The GHR bond is a soft and sturdy elastomer-based bond. Mounted grinding wheel in cylindrical shape, for fine grinding of small surfaces.

Advantage:
- Produces a fine, shiny surface finish.
- Soft grinding with a longer tool life.
- Produces very good surface quality.
- High economic efficiency thanks to long tool life and high stock removal rate.
- Maximum working convenience through precise concentricity.
Application:
- Recommendations for use: Depending on the intended use, profile using a dressing diamond or ceramic dressing stone at a low rotational speed. For the best results, use at a recommended cutting speed of 20-25 m/s.
- Applications: Step-by-step fine grinding
- Drive types: Flexible shaft drive; Straight grinder
