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.

The rhomboidal shape even enables work to be effortlessly performed on hard-to-reach places such as corners. With a diamond cut-off wheel, the blocks can be minimized and adapted to the respective application as required.

Poliflex fine grinding tools with the PUR bond are manufactured with green silicon carbide (SiC). The PUR bond is a very soft bond which is available in two hardness grades (PUR-W, PUR-MH). It is homogeneously interspersed with abrasive grain.

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.
Highly flexible, enabling optimal adjustment to the contour.
Cool and very gentle grinding thanks to open structure and elastic bond.
Produces a fine, matt 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 10-15 m/s.

Ordering notes

Please complete the description with the desired grit size.

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; Cast steel; Copper; Hardened, heat-treated steels over 1.200 N/mm² (< 38 HRC); Stainless steel (INOX); Steel materials with a hardness > 54 HRC; Steels up to 1,200 N/mm² (< 38 HRC); Zinc

Applications: Step-by-step fine grinding; Structuring (matt finishing, brush matting and satin finishing)

Drive types: Manual application
