Problems solved by technology
A point is also reached where too much of the overall surface area of the abrasive article is left for voids, and the abatement or overall life of the abrasive article is reduced by more than a practical, usable, or economical amount
Producing complex patterns of many holes can also be expensive, given the wear and tear on the dies and the cost of converting the web of abrasives into discs and sheets with precise hole patterns
But while still desirable for many applications, equivalent dust collection is not achieved with fewer larger holes, so in previous products there has been a trade-off between hole count and abatement to enhance both dust collection and abatement

Embodiment Construction
[0032] The present invention takes the approach of understanding that not only a uniform level of dust removal across the surface of the abrasive article is required for good performance, this should ideally take into account the situation where the abrasive article is used to provide orbital and / or rotating tools for the abrasive article in use. For example, a random orbit or dual action (DA) type sander, such as the 3M Random Orbit Sander range from 3M Company above, not only rotates the abrasive article, but moves it in an elliptical orbital pattern, which translates the translational component of motion impart rotational motion to the abrasive article. For abrasive articles, such as discs that rotate during use, the relative linear velocity near the center of the abrasive disc is significantly lower than the linear velocity at the outer edges of the disc, which depends on the rotational speed of the abrasive disc.
[0033]Without being bound by theory, it is believed that ...

Abstract
An abrasive article and an adapter therefore are disclosed. The abrasive article comprises a backing and an abrasive coating on a surface of the backing, and has a centre point and a periphery and the abrasive coating forming a work surface. A plurality of holes extending through the backing and the abrasive coating are provided, through which particulate material may be extracted. The work surface is divided into at least a first inner and a second outer zone, the second zone being concentric with the first and the centre point. Each zone has at least one hole, wherein in each of the first and the second zone the sizes of the holes and their total number forms a hole density for that respective zone. The hole density of the first zone is less than the hole density of the second zone. The adapter has the mounting surface for the abrasive article adapted in a similar manner.
Description
technical field [0001] The present invention relates to abrasive articles, in particular, to abrasive articles comprising a backing and an abrasive coating on a surface of the backing, the abrasive article having a central point and a perimeter; and a plurality of apertures passing through the backing and the abrasive coating, With adapters for abrasive articles that are also provided with holes through which particulate matter can be extracted. Background technique [0002] Many sanding and abrasive processes are performed in a dry environment, ie, an environment in which no lubricant is used to treat the workpiece. One situation where this occurs is, for example, the sanding of painted workpieces, such as the correction of paint or painted surfaces on motor vehicle parts during repair processes, or the down sanding of primers and fillers used in such processes. This produces fine particles commonly referred to as "dust" (such as paint chips), which, in addition to needing...
