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 LR bond are manufactured with white aluminium oxide. The LR bond is a hard, sturdy bond. Suitable for use on surfaces.

Mounted grinding wheel in ball shape for fine grinding inner radii, contours and transitions.

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.

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 15-20 m/s.

Safety notes

For safety reasons, the maximum permitted rotational speed indicated must never be exceeded.
The clamping length of the shank has to be at least 10 mm.

Materials that can be worked: Aluminium; Brass; Bronze; Cobalt-based alloys; Copper; Hardened, heat-treated steels over 1.200 N/mm² (< 38 HRC); Nickel-based alloys (e.g. Inconell and Hastelloy); Steel materials with a hardness > 54 HRC; Titanium; Titanium alloys

Applications: Step-by-step fine grinding

Drive types: Flexible shaft drive; Straight grinder
