HAND-HELD MACHINE TOOL FOR SANDING OR POLISHING A WORKPIECE ADAPTED FOR REALIZING TWO DIFFERENT TYPES OF WORKING MOVEMENTS

摘要

The invention refers to a hand-held machine tool (1) for sanding or polishing a workpiece, the machine tool (1) comprising: a housing (2), a motor (4) for actuating a tool shaft (5) of the machine tool (1) and for making the tool shaft (5) rotate about its axis of rotation (6), and a backing pad (3) for releasable attachment of a sanding element or a polishing element thereto and eccentrically attachable to the tool shaft (5) by means of an eccentric element (11) in such a way as to allow the backing pad (3) to perform a working movement, wherein the machine tool (1) is adapted for realizing two different types of working movements of the backing pad (3) attached thereto. It is suggested that the housing (2) of the machine tool (1) comprises a plurality of first magnetic elements (16) facing the backing pad (3), and that the backing pad (3) attached to the eccentric element (11) comprises a plurality of second magnetic elements (17) facing the housing (2), and wherein the machine tool (1) is adapted for realizing a first type of working movement if a magnetic force is active between at least some of the first and second magnetic elements (16, 17) and a second type of working movement if no magnetic force is active between the first and second magnetic elements (16, 17).
