“以锯带刨”就是木材在锯割过程中能同时完成刨削加工的一项新技术。由于它能提高木材利用率、提高生产效率和节约劳动力,所以受到了普遍的欢迎。实现“以锯带刨”的关鍵是锯片,这种锯片与普通锯片的不同点是:(1)锯齿在锯片平面上不向左右两侧弯曲,并且齿顶是一极锐利的“尖角”。(2)对每相邻的锯齿,交错地自两边平面向左右侧刃磨出斜角及具有一定角度的刃倾角,形成“刃”(图1)。锯片工作时借“尖角”切断木材纤维组织,同时又靠“刃口”起刨削作用。
“Saw band sawing” is a new technology that can be used for shaving of wood during sawing. It has gained widespread popularity because of its ability to increase wood utilization, increase productivity and save labor. The key to achieve “sawing belt” is the saw blade. The difference between this saw blade and ordinary saw blade is that: (1) sawtooth does not bend to the left and right sides in the plane of the saw blade, and the top of the tooth tip is sharp The “sharp corners.” (2) For each adjacent sawtooth, the bevel angle and the bevel angle with a certain angle are alternately ground from both sides of the plane to the left and right blades to form a “blade” (FIG. 1). Saw blade work by “sharp corners” cut wood fiber tissue, but also by “cutting edge” from the shaving effect.
