摘要: There is provided a tool blade, comprising a backing strip particles of abrasive material and a binder layer of binding material which binds the abrasive particles along an edge of the backing strip, wherein the edge of the backing strip is pre-formed with teeth, on which the abrasive particles are bound by the binding material. A profiled cutting portion extends beyond the pre-formed teeth. The pre-formed teeth are shaped as generally triangular waves or are flattened at least partially along an upper edge on which the cutting portion is at least partially disposed. A method of making such a blade is also provided.

摘要: A ring forming step includes welding opposite ends of a band saw blade including a body part having a band shape, and a tooth part including a plurality of teeth formed on one side part of the body part, to form a ring shape. A polishing step includes polishing an inner surface, an outer surface, and an end face on a side opposite to the tooth part in the ring-shaped band saw blade subjected to the ring formation. A tip tooth tip forming step includes positioning, after the polishing step, the ring-shaped band saw blade subjected to the ring formation by use of one of the inner surface and the outer surface, and the end face as references, joining a cutting tip to tooth tips of the plurality of teeth by welding, and polishing the joined cutting tip to form a tooth tip shape.

摘要: There is provided a method of making a tool blade, in which a backing strip is provided, binding material in powder form is cascaded onto the backing strip, abrasive particles are provided and the binding material powder is heated by laser beam to form a binder layer which binds the abrasive particles to the backing strip. The laser beam is used to form discrete regions of binder layer as teeth. The binding material is typically braze material. A blade made according to the method is also provided.

摘要: A wood or resin cutting tool with improved durability is provided. The wood or resin cutting tool is composed of a base material made of steel or a cemented carbide alloy, and a coating formed on at least one of the rake face and the clearance face of the cutting tool. The coating includes a periodic structure layer made of chromium oxynitride, in which high oxygen regions having a high concentration of oxygen in the texture and low oxygen regions having a lower concentration of oxygen in the texture than the high oxygen regions periodically exist in the thickness direction of the coating. The periodic structure layer is formed such that the nitrogen concentration periodically turns high and low in the thickness direction of the layer corresponding to the high oxygen regions and the low oxygen regions.
