Description

POLINOX cross buffs consist of non-woven polyamide abrasive, into which abrasive grain is integrated. The non-woven abrasive is star-shaped and stacked in layers which are connected in the centre. Particularly suitable for narrow application areas and hard-to-reach places such as drilled holes and indentations. POLINOX cross buffs are suitable for cleaning, deburring and fine grinding of inner surfaces and contours.

Advantages

Highly flexible, enabling optimal adjustment to the contour.
Cool grinding and low thermal load on the workpiece.
The open structure and high flexibility of the non-woven material prevents tool clogging.

Recommendations for use

For the best results, use at a recommended cutting speed of 10-20 m/s. This provides an ideal compromise between stock removal rate, surface quality, thermal load on the workpiece and tool wear.

Ordering notes

Please order compatible arbor separately.

Safety notes

The maximum permitted peripheral speed is 32 m/s.
For safety reasons, the maximum permitted rotational speed indicated must never be exceeded.
