Grinding tool for wet grinding workpieces ABSTRACT OF DISCLOSURE
A grinding tool for wet grinding workpieces, formed by a porous and elastic tool body to which granular grinding material is fixed over at least parts of the outer surface.
The grinding material is fixed in a manner to enable water to be pressed out of the tool body and through the surface covered by grinding material, to thereby assist the wetting of the effective working area.

1 In treating automobile bodies before applying varnish, the sheet iron is ground by using water resistant grinding paper. This operation involves the danger that the work-piece to be treated is not sufficiently wetted, which may cause undesired grinding marks.
It is an object of the present invention to provide a new and useful grinding tool for wet grinding workpieces which is easy to manufacture and handle and which ensures better wet grinding.
STATEMENT OF INVENTION
The grinding tool according to the invention comprises a poraus absorbent tool body to which granular grinding material is fixed at least over parts of its outer surface region.
This construction with its interrupted adhesive layer allows water absorbed in said body to pass between each individual grain of the grinding material, thereby to give the necessary wetness to the workpiece which is to be treated by the tool.
The grains of the grinding material are preferably fixed by means of a water resistant adhesive in the outer layer of the body. The body is preferably a sponge or a sponge-like element, i.e. a porous absorbent element which is resiliently compressible. It is particularly useful to coat the whole sur-face of the tool with grinding material. This feature still permits water to penetrate into and flow out of the tool body.
According to a further aspect, the invention consists in a process for manufacturing the grinding tool, comprising the steps of covering said tool body with an adhesive and thereafter, with the adhesive still in its plastic state, applying the grains of the grinding material onto the thus pretreated body.

`" 1~47771 The adhesive may be applied in any conventional manner to the tool body, e.g. by spraying or by using a painting brush.
The application of the grains of the grinding material to the tool body pretreated with adhesive is preferably made by blasting, e~g. by using compressed air. The conveying medium may be preheated.
DESCRIPTION OF DRAWINGS
Further details of the invention may become apparent in the following description of the accompanying drawing which is a perspective view of a grinding tool according to the invention with a part cut away.
DESCRIPTION OF PREFERRED EMsODIMENTS
The tool consists of a tool body in the form of a porous absorbent sponge 1. Granular grinding material 2 is stuck to the o~ter surface region of the sponge 1, i.e. to the surface itself and to the surface of the pores and voids directly under the surface. The grinding material consists of conven-tional corundum grains or similar suitable minerals.
For fixing the grinding material grains any suitable ~-adhesive may be used, particularly water resistant resins.
The grinding tool may be manufactured by applying an adhe-sive to a sponge (eOg. by spraying) and blasting grinding material grains against its surface thereafter by means of compressed air. The grinding material penetrates into the superficial pores and voids of the sponge and is fixed by the adhesive.
The grinding tool shown in the drawing is able to absorb and deliver the desired quantity of water despite the grains of grinding material stuck thereto. This water can be delivered directly onto the working area during the working operation, ~47771 by pressing appropriately on the sponge body, thereby resulting in an excellent wet grinding effect. As the body of the tool consists of porous absorbent material, it cannot form a closed layer, i.e. a layer through which water cannot penetrate. This contrasts with known cleaning tools in which grinding material grains are fixed to a water resistant substrate having fixed on its back fact a sponge-like bodyO

Claims (5)
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. A grinding tool for wet grinding workpieces com-prising a porous absorbent tool body to which granular grinding material is affixed, at least over parts of its outer surface region, said grinding material bieng finely and uniformly distributed over the outer surface and the surface of the pores in said outer region and affixed by means of a water resistant adhesive, the adhesive coating being interrupted substantially between each of the adjacent grains applied to the body, to enable water to be pressed out of the tool body and through the surface covered with grinding material.
2. A grinding tool according to claim 1, wherein said tool body is a sponge or sponge-like element.
3. A process for manufacturing a grinding tool for wet grinding workpieces comprising applying an interrupted, water resistant adhesive layer over the outer surface of a porous absorbent tool body and finely and uniformly distributing grinding material over the outer surface region of the tool body which is affixed at least over parts of the outer surface region by the interrupted adhesive layer in a manner to enable water to be pressed out of the tool body and through the surface covered with grinding material.
4. A process as claimed in claim 3, wherein said adhesive is sprayed onto the tool body.
