摘要： A structure for a backing plate of an abrasive disk is disclosed. The structure includes layers of abrasive resin interspersed with layers of reinforcing fiberglass. The layers are generally disk shaped and cover certain radial intervals of the entire backing plate between the inner diameter and the outer diameter. For example, a radial stress profile plotting the stress along a radial line from inner to outer diameter can be determined. The amount and radial positioning of reinforcing layers (e.g., reinforcing fiberglass) may then be determined. An appropriate amount of reinforcing layers may then be placed within the radial intervals that experience the highest stress.

摘要： An abrasive disc assembly for a tool having an externally threaded, motor-driven spindle. The assembly includes an abrasive disc having a central bore formed therethrough and a male portion having an internally-threaded hub portion and a flange portion. The outer dimension of the hub portion is sized to be received within the central bore and the internally-threaded hub portion is enmeshingly engagable with the externally threaded, motor-driven spindle. The assembly further comprises an articulating locking finger extending from the male portion and having a retaining surface. The articulating locking finger is deflectable between a locked position and a deflected position. Finally, the assembly includes a female portion having a central cavity and an engagement surface. The central cavity receives the hub portion of the male portion such that the retaining surface of the articulating locking finger engages the engagement surface thereby releasably coupling the male portion to the female portion and retaining the abrasive disc therebetween.

摘要： An abrasive disc adapted to mount on a surface of a sander, such as an orbital sander, having either five or eight dust extraction holes is provided. The abrasive disc includes a plurality of apertures arrangeable to at least partially overlap each of the five or eight dust extraction holes of the orbital sander.
