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 likewise a soft yet sturdy elastomer-based bond. Suitable for use on edges.

Due to their construction, the small diameter variants are particularly suited to work on tight and hard-to-reach places.

Ideally suited to very fine grinding on all metallic materials, e.g. in tool- and mould-making, in the dental sector and in the jewellery industry.

Advantages

Produces very good surface quality.
High economic efficiency thanks to long tool life and high stock removal rate.
Maximum working convenience through precise concentricity.
Produces a fine, shiny surface finish.
Soft grinding with a longer tool life.

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.

Ordering notes

Please order compatible arbor separately.

Safety notes

For safety reasons, the maximum permitted rotational speed indicated must never be exceeded.

Materials that can be worked: Cast steel; Cobalt-based alloys; Hardened, heat-treated steels over 1.200 N/mm² (< 38 HRC); Nickel-based alloys (e.g. Inconell and Hastelloy); Stainless steel (INOX); Steel materials with a hardness > 54 HRC; Steels up to 1,200 N/mm² (< 38 HRC)

Applications: Step-by-step fine grinding

Drive types: Flexible shaft drive; Straight grinder
