FIELD: woodworking.
SUBSTANCE: invention relates to the woodworking industry. Cutting assembly of a circular saw machine comprises a support axis with bearings, a circular saw, clamping flanges, and a linear electric engine of direct drive of the saw. An additional linear electric engine is installed on the working section of the saw web in the diametrical plane thereof normally to the material feeding direction at a distance exceeding the height of the cut. The additional linear electric engine creates non-contact tensioning of the saw web in a local area of the working section of the saw web in the direction of the chord connecting the circumferential points of the geared crown at the entrance into and exit out of the cut.
EFFECT: higher rigidity and stability of the web of the circular saw in the cutting area.
