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 die-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.
Cost-effective due to durability and high stock removal rate.
Highly convenient to use due to precise concentricity.
Conforms to contours due to high flexibility.
Cool and very gentle grinding due to open structure and elastic bond.
Produces a fine, matte 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 best performance, use at a recommended peripheral speed of 2,000-3,000 SFPM.

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 must be at least 1/2".

Materials that can be worked: Aluminum; Brass; Cast steel; Copper; Hardened, heat-treated steels over 370 HV (38 HRC); Stainless steel (INOX); Steel materials with a hardness > 54 HRC; Steels up to 370 HV (< 38 HRC); Zinc

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

Drive types: Manual application
