Abstract
The tool body of the grinding tool consists of a holder for fixing the tool to the oscillating device and a flange of relatively soft, flexible material fixed thereto, supporting the abrasive paper and designed or arranged with axial dimensional flexibility at its outer edge. This results in the advantage that, in particular, increased pressure via the tool edge on the grinding surface is avoided. Very soft and very fine work can thus be carried out, so that when grinding or polishing, for example, an unsatisfactory new finish the defects can be perfectly eliminated by the grinding tool according to the invention and, under these circumstances, the peripheral edge of the tool does not act rigidly on the finish, leaving traces behind.
Claims20
A grinding tool, for a hand-held oscillating device, comprising:
- a tool body which is attachable to the oscillating device and has an active side on which abrasive paper is replaceably fixed, the tool body consisting of a holder for fixing to the oscillating device, and a flange of soft, flexible material supporting the abrasive paper, the flange being coaxial with the holder and having an outer edge that extends beyond a supporting surface of the holder for the flange with axial dimensional flexibility, the holder being configured as a joint having a bearing block which supports the flange, a joint head pivot member fixable to the oscillating device, and a joint pin arranged to connect the pivot member to the bearing block.
A grinding tool, for a hand-held oscillating device, comprising:
- a tool body which is attachable to the oscillating device and has an active side on which abrasive paper is replaceably fixed, the tool body consisting of a holder for fixing to the oscillating device, and a flange of soft, flexible material supporting the abrasive paper, the flange being coaxial with the holder and having an outer edge that extends beyond a supporting surface on the holder for the flange with axial dimensional flexibility, the holder being essentially cylindrical at least on the flange side, and being arranged with its axis standing perpendicularly on the flange, the holder being diametrically recessed on a side facing the flange.
A grinding tool, for a hand-held oscillating device, comprising:
- a tool body which is attachable to the oscillating device and has an active side on which abrasive paper is replaceably fixed, the tool body consisting of a holder for fixing to the oscillating device, and a flange of soft, flexible material supporting the abrasive paper, the flange being coaxial with the holder and having an outer edge that extends beyond a supporting surface of the holder for the flange with axial dimensional flexibility, the flange being a cylindrical disk arranged concentrically to the holder.
A grinding tool, for a hand-held oscillating device, comprising:
- a tool body which is attachable to the oscillating device and has an active side on which abrasive paper is replaceably fixed, the tool body consisting of a holder for fixing to the oscillating device, and a flange of soft, flexible material supporting the abrasive paper, the flange being coaxial with the holder and having an outer edge that extends beyond a supporting surface of the holder for the flange with axial dimensional flexibility, the flange being formed as a truncated pyramid that tapers toward the holder, an end surface of the holder being of equal size with a small base surface of the flange which rests on it;
- and
- a cylindrical supporting disk arranged between the holder and the flange, the supporting disk having a diameter that is greater than an outer diameter of the holder and of equal size to the small base of the flange.
A grinding tool, for a hand-held oscillating device, comprising:
- a tool body which is attachable to the oscillating device and has an active side on which abrasive paper is replaceably fixed, the tool body consisting of a holder for fixing to the oscillating device, and a flange of soft, flexible material supporting the abrasive paper, the flange being coaxial with the holder and having an outer edge that extends beyond a supporting surface of the holder with axial dimensional flexibility;
- a feed line provided axially through the holder and the flange so as to open toward the working surface to permit feeding of processing additives;
- and
- a container and a flexible feed hose arranged to connect the feed line to the container, the container being one of replaceable and refillable, and one of having elastic walls and being axially compressible as a bellows for selective and positional release of the additive.
