Machine tool for grinding large surface, has grinding disks coupled to different connecting portions and including grinding zones, where grinding disks are rotated by rotary support in synchronism to form joint grinding plane

摘要

The tool has a tool body (1) including a drive motor (11) and a spindle driven in axial rotation by the drive motor. A rotating support (3) is coupled to and driven by the spindle to form a plane of rotation, where the support includes connecting portions (31) equidistantly spaced from each other and annularly formed on the plane of rotation. Grinding disks (2) coupled to different connecting portions include grinding zones (21) located at the same horizontal level, where the grinding disks are rotated by the rotary support in synchronism to form a joint grinding plane.
