一台出色的机器在工作着,它发出了有节奏的、均匀的轰隆声。机器虽然不大,但是它的工作却使人非常吃惊。工作台上放着一块准备加工的方木。操作工人只要轻轻地按动一下按钮,锋利的钢刀便会按照规定尺寸锯切木材。切割好的另件,表面常光滑。使人感到惊奇的是,机器锯切木材时,竟不出一点磨木材,甚至连锯末都没有!大家知道,制作木板、门、窗、家具和其他木器时,木材的有效利用率仅为25-30％。大部分木材在加工过程中都变成了废木料和锯末。为了合理使用木材资源,降低木材加工的废料率,不久前,苏联莫斯科林业技术学院在弗·姆·蒙日斯教授领导下制造了一种新的木材加工机器。这种机器能够锯切任何木料,并且不出一点锯末。机器的构造并不复杂。钢制的锯刀安装在刀架上,刀架与振动锯架相连。振动动作由两台N-11O
An excellent machine is working. It emits a rhythmic, even rumbling sound. Although the machine is not large, its work has surprised people. On the workbench stood a piece of wood to be processed. As long as the operator gently presses the button, the sharp steel knife cuts the wood according to the specified size. The cut pieces are often smooth on the surface. Surprisingly, when the machine saws wood, it does not produce a little bit of wood, even sawdust! As we all know, the effective utilization rate of wood is only 25 when making planks, doors, windows, furniture, and other woodware. -30%. Most of the wood has turned into waste wood and sawdust during processing. In order to rationally use timber resources and reduce the scrap rate of wood processing, not long ago, the Soviet Moscow Institute of Forestry Technology created a new wood processing machine under the leadership of Prof. Monzhez. This kind of machine can saw any wood without a little sawdust. The construction of the machine is not complicated. The steel saw blade is mounted on the knife holder, and the knife holder is connected with the vibration saw frame. Vibration action by two N-11O
