Saw blade having liquid transport cavity for use with lubricating guide support assembly. (Patents).
A saw arrangement includes the combination of a circular saw blade
and a lubricating guide support assembly. The circular saw blade
includes a saw plate having openings formed therein and carbide insert
teeth disposed circumferentially about the saw plate. The lubricating
guide support assembly includes two guide supports each having a bearing
surface disposed immediately adjacent opposite sides of the saw plate at
a spacing to the cutting area for proper alignment of the saw blade
during cutting. At least one of the guide supports includes a recessed
area containing liquid exposed to the saw plate whereat a thin film of
the liquid is applied to the saw plate as it passes by the recessed area
during cutting. The openings are arranged on the saw plate to pass by
the recessed area and are dimensioned to receive liquid therein for
transport away from the recessed area. When each opening clears the
bearing surfaces of the guide supports the liquid transported therein is
distributed to the saw plate and the cuttin g area including the carbide
insert teeth by air turbulence and inertial forces. Such a saw blade
having a thickness at least as small as 0.080 inches is used to cut
lumber from Southern Yellow Pine.
