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.
