| 摘要 |
The invention relates to circular plane saws for combined longitudinal and transversal wood sawing-cutting-planing and can be used for the wood-working industry, for example for high-quality solid timber cutting, for plywood, laminate, chipboards, laminated boards and other similar wood and wood-based materials tailoring. The aim of said invention is to improve the working efficiency of saws. Said invention is characterised in that the right and left saw teeth are alternately arranged on the body of the saw and provided with a helically-shaped front cutter part which is embodied in the form of a conventional tooth whose rear part (of the front cutter part) successively transforms into a rear planing-cutting part in the form of a disc fragment (part) whose working area height is less than the radius of the given disc section. Only the helically-shaped teeth are disposed on the saw body, the front cutter parts and the rear planing-cutting parts thereof being embodied in such a way that they have similar or different thickness and the tips thereof are positioned on the same or different circumferences (diameters) of the saw. |
