Tool

摘要

The machining tool has a circular disc (2) connected to a bracing plate. The circular disc and the bracing plate has a coupling (20) and a counter coupling having walls (23) formed of alternating convex wall sections (24) bent inwards towards the central axis (10) and the concave wall sections (25) bent outwards away from the central axis. The maximum radius of the convex and concave wall sections of the coupling is smaller than the maximum radius of the convex wall and the concave wall sections of the counter couplings, respectively.
