ABSTRACT:
Grinding with known grinders such as corner, belt or vibratory grinders poses insoluble problems, such as the grinding of inner edges set at an angle to each other for example in retainer strips of window and door glasses. A portable grinder has thus been developed in which the grinding or sanding tool (3, 20, 30) effects an oscillatory movement which, unlike in the state of the art, is effected around a fixed axis of the apparatus (29) with a minimum pivoting angle, preferably between 0.5.degree. and with a high pivoting frequency of between ten thousand and twenty five thousand vibrations per minute. This different oscillation movement makes it possible to provide the grinding or sending tool with almost any shape. Furthermore, grinding does not inevitably have to be made with the transverse surface of the tool (3), in particular the perpendicular surface, in relation to the diametrical axis (29) but it is also possible to use a surface which is almost parallel to the first or is even arched. One may also imagine the use of the hole region of the grinding or sanding tool. Preferably, as in the majority of grinders commonly used today, the grinding dust is removed by suction. It is also possible to form in the grinder, in a very advantageous manner, pockets or similar arrangements to contain an abrasive paste for polishing as well as for an emery paste. If emery paper, abrasive material or similar are used, these may be fixed to the tool or exchanged according to a known process or in accordance with the above-described process.
