FIELD: wood industry.
SUBSTANCE: forming of toothed cutting edge is operated, the cutting blade sharpening elements and grinding operation interdental depressions of the saw by abrasive tool. The treatment zone of interdental cavities of toothed edge of the saw blade is operated by rotating disk. The disc is made of wear resistant metal or ceramic. Disc material is harder than the material, from which the saw blade is manufactured. The heating of the contact zone of the depression is operated to the state of plasticizing the metal layer on the surface of inter-toothed depression due to the contact friction drive surfaces and depressions.
EFFECT: improved durability and serviceability of saws.
