Definitions

  • WO2012/034785 discusses the use of many small holes for improved dust extraction, although rather than proposing a uniform distribution of holes across the surface of the abrasive article, the use of a Fibonacci sequence, or golden number, to generate a hole distribution is discussed, showing that a non-uniform arrangement also gives beneficial dust extraction results.
  • a Fibonacci sequence or golden number
  • the adapter is in the form of a circular back up pad.
  • the adapter may further comprise a third zone, positioned between the first and second zones, in which there are no holes.
  • the adapter may further comprise a third zone, positioned between the first and second zones, comprising at least one hole.
  • the amount of dust extracted will be proportional to the amount of open area, i.e. the surface area of the holes 10 provided across the abrasive disc 11. To determine the surface area of the holes required, the following equation is used:
  • Each disc comprised a centre hole with the remaining holes distributed evenly across the surface of the abrasive disc, as illustrated in Figure 4 below. All tests were carried out on a Fanuc Robotics robot using a 150mm National Detroit Air Powered Sander, available from National Detroit, 1590 Northrock Court, Rockford, Illinois 61103, US.
  • a 600 x 600mm primer panel was painted with a Standox VOC System filler, available from Standox, Wedgwood Way, Stevenage, Hertfordshire, SGI 4QN to a thickness of approximately ⁇ , weighed, and the weight recorded. Before sanding, the surface of the primer panel was wiped down with a clean tack cloth, which was then disposed of.
  • FIG. 4 is a schematic diagram of the fifteen hole 16 and seventy-eight hole 17 abrasives used in comparative experiments with the first and second embodiments of the present invention. This illustrates that the present invention offers similar or improved performance when compared with traditional hole patterns and multihole abrasive discs, as the ratio between the surface area of abrasive coating within the zone and the surface area of the holes is optimised for the hole size and distribution.
  • the level of accuracy of the constant K will also be influenced by the method used to form the holes in the abrasive article.
  • the abrasive article may comprise a third zone, positioned between the first and second zones, in which there are no holes.
  • the abrasive article may comprise a third zone, positioned between the first and second zones, comprising at least one hole.
  • the holes 10, 15 are distributed evenly around the centre point 12. However, this need not be the case.
  • the holes may be distributed in any fashion, whether this forms a regular array or pattern or not, since as long as the above Equation 1 and Equation 2 are satisfied the dust extraction performance of the abrasive article is optimised.
