<p>FIELD: mechanical engineering, in particular, production of cutting tools. SUBSTANCE: disk saw 1 has teeth with side surface extending in parallel with first side surface 2 of disk saw. When double-disk saw is assembled, first side surface 2 is faced toward adjacent cooperating disk saw. Saw tooth surface has portion offset from first side surface 2 toward central surface of disk saw and is spaced from first side surface 2 by distance A , which is less than distance to central surface. Outer side surface of each tooth adjoining second side surface 3 of disk saw 1 has relatively straight part 4, positioned at periphery of tooth projecting beyond second side surface 3 and extending in parallel with it, and inclined part 5 whose angle of inclination relative to second side surface 3 defines rear tooth angle. Disk saw side surfaces are provided with at least one through opening or channel. In the process of rotation of disk saw in working direction, air is supplied in the form of air flow through these through openings or channels and directed from second side surface 3 of disk saw 1 to its first side surface 2, i.e. into space defined by two jointly working disk saws. EFFECT: increased efficiency and enhanced reliability in operation. 9 cl, 4 dwg</p> |
