Cutting blade for sawing .g. aluminum blocks in industrial application, has sawing and polishing teeth distributed along edge of body, and patches for forming respective stops tangent to plane parallel to running and penetrating directions

摘要

The blade (10) has sawing teeth (12A-12D) and polishing teeth (12E, 12F) that are distributed along an edge of a body (11). The teeth (12A-12F) comprise respective tungsten carbide based reinforcement patches (14A-14F) along a direction perpendicular to a running direction (L) and a penetrating direction of the blade. The patches (14E, 14F) form respective stops (22E, 24F) tangent to a plane parallel to the running and penetrating directions. Independent claims are also included for the following: (1) a method for sawing a piece (2) a piece comprising a sawn region.
