<p>The invention refers to a method for manufacturing a polishing pad (8) for a hand guided electric or pneumatic machine tool (1) having a working element (7) performing an orbital, random orbital and/or a rotational movement, the polishing pad having a plurality of layers which are inseparably attached to one another, the layers comprising:
- a damping layer (10) made of a resilient material,
- an adhesive layer (9) adapted for connection to a corresponding layer located at a bottom surface (7a) of the working element (7) of the machine tool (1), and
- a polishing layer (11) comprising microfiber adapted for polishing a surface of a work piece. In order to provide for a new method and a new polishing pad (8) which can better withstand the high demand in terms of stress, load and wear applied to the polishing pad (8) during the polishing process the following steps are suggested:
- providing a casting mold (20) having a recess (21) corresponding to the overall form of the polishing pad (8) and a lid (22) for closing the recess (21),
- placing the adhesive layer (9) into the recess (21) at the bottom (21a) of the casting mold (20),
- pouring the resilient material for the damping layer (10) into the recess (21) of the casting mold (20) on top of the adhesive layer (9),
- placing the polishing layer (11) on the resilient material,
- closing the recess (21) with the lid (22) and
- manufacturing the polishing pad (8) under external heat supply (T) until the resilient material of the damping layer (10) is cured.</p> |
