Polishing roller device for polishing object, has compressive force recognition device e.g. load cell, identifying compressive force, with which polishing roller is pressed against object, based on pretensioning force

摘要

The device has a tool main body (54) moving relative to an object to be polished, and a panel-bracket (78) moving relative to the tool main body in a relative motion direction. A pretensioning device e.g. compression spiral spring (100), pretensions the bracket with a pretensioning force relative to the main body. A compressive force recognition device e.g. load cell (120), identifies compressive force, with which a polishing roller (86) is pressed against the object, based on the pretensioning force.
