Abstract
A method for producing a preliminary material for a cutting tool and such a preliminary member, for example a preliminary material for a saw blade, a saw band, a cutting line, a punching knife, or a blade, wherein at least one first particulate cutting-edge material is applied to a planar carrier, the first particulate cutting-edge material is welded to the planar carrier, and the planar carrier is separated substantially along the weld joint thus produced.
Claims12
A method for producing a preliminary material for a machining tool, or for a saw blade, a saw band, a cutting line, a punching knife or a blade, the method comprising:
- introducing at least a first particulate cutting-edge material in a form of powder or granules into a depression formed on an upper side of a horizontally arranged sheet-like base;
- welding the first particulate cutting-edge material to the upper side of the horizontally arranged sheet-like base;
- turning the horizontally arranged sheet-like base by 180° so that an underside of said sheet-like base faces upwardly;
- introducing said first particulate cutting-edge material in the form of powder or granules into another depression formed on the underside of said sheet-like base;
- welding said first particulate cutting-edge material to the underside of said sheet-like base;
- and
- separating the sheet-like base along a center line of the welded connection thus separating the sheet-like base substantially along the welded connection thus produced to form at least two sheet-like base portions each comprising the welded first particulate cutting-edge material along an edge thereof.
A method for producing a preliminary material for a machining tool, or for a saw blade, a saw band, a cutting line, a punching knife or a blade, the method comprising:
- forming depression cut-outs on an upper side and an underside of a sheet-like base;
- introducing at least a first particulate cutting-edge material into said depression cut-outs of said sheet-like base;
- welding the first particulate cutting-edge material to the sheet-like base by a first welding head and forming a first alloying zone between the sheet-like base and the first particulate cutting-edge material;
- introducing at least a second particulate cutting-edge material to the welded-in first particulate cutting-edge material;
- welding the second particulate cutting-edge material by a second welding head and forming a second alloying zone between the first particulate cutting-edge material and the second particulate cutting-edge material, thereby forming a two-layered welded connection;
- and
- separating the sheet-like base along a center line of the two-layered welded connection to form at least two sheet-like base portions each comprising the welded first and second particulate cutting-edge materials along an edge thereof.
