Title:
SAW BLADE STRCTURE OF DUAL-BLADE SAW
Document Type and Number:
WIPO Patent Application WO/2013/131350
Kind Code:
A1
Abstract:
A saw blade structure of a double-blade saw comprises a first saw blade (1) and a second saw blade (3) rotating in opposite directions around a same axis. The root circle part of one saw blade is provided with three or more convex ribs (5), central axes of the convex ribs do not pass through the centre of the saw blade. Since the convex ribs play a role of separating the first saw blade and the second saw blade during the operation of the dual-blade saw, chip removal and heat dissipation effects of the saw blades are enhanced.
