摘要 |
Disposable cutting blades and method for producing disposable cutting blades with profiled cross sections for a device for chipping wood. The method includes heating a primary material of a hardenable material in a soft-annealed state having a worked surface to a temperature above room temperature, but below a conversion temperature Ac1, rolling the primary material to form a profile blank with at least one precisely gaged guide path in a base body in cross section and with an increased thickness of at least one edge region, a metal-removing working of at least one edge region in a longitudinal direction of the profile blank to form a cutting edge and to form scratching edges in a spaced manner directed perpendicularly to the cutting edge, and continuously hardening the edge regions of the cutting blade. |
