Tungsten Carbide Saw Blade Stabilizers

Since carbide saw blades are circular, they are radially the stiffest elements of the power train in the direction of the feed, but very unstable perpendicular to the feed direction. Due to the thin blade body the blades must be stabilized to minimize the side vibration amplitudes. When the first experiments with carbide saws were made, the blade stabilizer was developed using two plastic coated ball bearings mounted on eccentric shafts and supported by a welded bracket to the gearbox.  Recently the new patten has been developed, a pair of front stabilizers for machines arranged close to the point at which the blade enters the material. These stabilizers hydraulically extend, when the carbide teeth have moved past the stabilizer tips before cutting and stabilize the blade which also help to guide the blade into the cut to improve the accuracy.
