<p>The disc (1) has roof sides (3a,3b) including grinding layers, where straight and convex surface contour areas (13,15) of a chipping tool (11) with one of the roof sides and concave surface contour area (21) of the chipping tool with other roof side are ground. The disc is designed as a dual cone disc, where a rotation axis coincides with a cone axis. The roof sides are formed respectively on a plane, which is in an angle lesser than ninety degrees. An independent claim is also included for a method for grinding a chipping tool.</p> |
