| 1 刨切机和旋切机的比较 Comparison of 1 cutting machines and rotary cutting machines 木材刨切机是生产单板和微薄木的主体设备。按照刨刀相对于水平面的运动方向来分类，则木材刨切机可分为立式和卧式两大类；根据刨切方向相对木方纤维长度方向垂直还是平行，又可将刨切机分为横向刨切机和纵向刨切机。现代的刨切机的外形尺寸仅为过去刨切机的1／3，结构紧凑，质量轻，安装调试容易；可连续生产，节省装卡木材的时间，生产效率高；工作极平稳，几乎听不到噪声。旋切机也是生产单板的主要设备之一，从某种意义上来说，比刨切机使用得更广泛。旋切机按木段是否绕自身轴线旋转可分为同心旋切和偏心旋切两类。同心旋切机中又分为卡轴旋切机和无卡轴旋切机种。偏心旋切可获得美观的径向花纹，但生产率比同心旋切低。旋切机一般体积大而且结构复杂，上机前需要原木定心，若定心不准，开始旋切时会旋出续的单板带或窄单板。碎单板或窄单板越多，损失的材质好的边材单板也越多，不利于生产的连续化。原木有弯曲、截面不规则和两端有大小头(尖削度)等易造成旋出的单板为碎单板，浪费木材。并且当原木直径减小到一定程度时，就不能再继续旋切(即剩余木芯造成木材浪费)。而刨切机的缺点是：刨切单板的宽度窄，一般为300rnm有特殊要求的场合。 Wood planer is the main equipment for producing veneer and thin wood. According to the plane relative to the horizontal direction of movement of the classification is wood planing machine can be divided into vertical and horizontal two categories; according to the direction of relative planing wood fiber length direction perpendicular or parallel, and can be divided into horizontal planer planing machine and vertical planing machine. The size of modern slicer cutting machine is only 1 / 3 plane past, compact structure, light weight, easy installation and debugging; continuous production, saving wood clamping time, high production efficiency; very smooth, almost hear the noise. Rotary cutting machine is also one of the main equipment for producing veneer. In a sense, it is used more widely than cutting machine. The rotary cutting machine can be divided into two types: concentric rotary cutting and eccentric rotary cutting according to whether the wood section rotates on its own axis. Concentric rotary cutting machine is divided into clamping axis rotary cutting machine and non - clamping shaft cutting machine. Eccentric cutting can achieve beautiful radial pattern, but the productivity is lower than concentric rotary cutting. Rotary cutting machine in general size and complex structure, before the machine needs log centering, if the centering is not allowed, the beginning of the spin, will spin out the continued single plate or narrow single plate. Broken board or veneer more narrow, sapwood veneer loss of good material more and more, is not conducive to continuous production. Wood bending, irregular cross-section and ends with large head (taper) and so easy to cause the single plate screwed out for broken veneer, wood waste. And when the log diameter is reduced to a certain extent, it can not continue to spin (that is, the remaining wood core waste wood). The disadvantages of the planer are: the width of the planed veneer is narrow, which is generally 300rnm. ④低速、大转矩。与电磁马达相比，超声波马达最显著的特点是低速下具有大力矩输出的特性。超声波马达的力矩密度(力矩重量比)是电磁马达力矩密度的100~1000倍以上。 Low speed and big torque. Compared with electromagnetic motors, the most remarkable feature of ultrasonic motors is the characteristics of large torque output at low speed. The torque density (torque, weight ratio) of an ultrasonic motor is more than 100~1000 times that of the electromagnetic motor. ⑤结构简单灵活、运动形式多样。超声波马达一般由定子、转子(或移动体)两部分组成，并且可非常方便地将马达的定子、转子分别与运动系统中的固定部件和运动部件做为一体。超声波马达有圆环、圆板、方板、圆柱和球形等多种灵活的结构形式，并且非常容易实现多种形式的运动，如旋转运动、直线运动、二维平面运动和三维运动。 The structure is simple and flexible, and the form of movement is diverse. Generally, the ultrasonic motor consists of two parts, stator, rotor (or moving body), and the stator and rotor of the motor can be conveniently integrated with the fixed parts and the moving parts in the moving system. The ultrasonic motor structure, circular plate, side plate, cylindrical and spherical and other flexible, and very easy to implement various forms of exercise, such as rotary motion, linear motion, 2D motion and 3D motion. ⑥寿命、噪声和可靠性问题。由于超声波马达的驱动绝大部分是接触式的，这必然带来定、转子间的摩擦损耗问题。目前，所研制的小功率超声马达的连续工作寿命一般在几千小时左右。超声波马达寿命短，可靠性差，以及工作不稳定等是制约其实用化和产业化所需急待解决的问题。但目前在某些特殊工作性质或对马达有特殊要求的场合，超声波马达仍可充分发挥其力矩密度大、结构灵活、无电磁干扰和具有大的静态保持力矩等特点的优势。超声马达广泛应用在航空航天、精加工设备、汽车行业、有强磁场或对磁场有要求的科学仪器或医疗器械、精密仪器仪表、办公自动化设备、微型机械、军事工业和半导体加工行业等相关领域。左右或更窄，均需拼接，木材利用率低，而且刨切的生产率仅为旋切的10％左右；目前使用的刨切机仅刨切微薄木。 The life, noise and reliability problems. Because the driving of ultrasonic motor is mostly contact type, this will inevitably bring about the friction loss between stator and rotor. At present, the continuous working life of the small power ultrasonic motor is usually about several thousand hours. The ultrasonic motor has the problems of short service life, poor reliability and unstable work. It is a pressing problem that restricts the application and industrialization. But in some special nature of the work or the motor has the special requirements of the occasion, can give full play to the ultrasonic motor torque density, flexible structure, no electromagnetic interference and high holding torque etc. advantage. Ultrasonic motor is widely used in aerospace, precision processing equipment, automotive industry, with a strong magnetic field or the requirements of the scientific instruments and medical equipment, the magnetic field of precision instruments, office automation equipment, micro machinery, military industry and semiconductor processing industry and other related fields. The ratio of wood utilization is low, and the planing productivity is only about 10% of the rotary cutting. The planing machine used at the moment only cuts the veneer. 2 旋切单板和刨切单板的比较 Comparison of 2 rotary veneer and sliced veneer 单板加工是胶合板、单板层积材(LVL)等人造板材生产的重要工序，目前国内外单板加工的两种主要方式是旋切和刨切，相应加工的单板称之为旋切单板 Veneer processing is an important process for plywood and laminated lumber (LVL) and so on. At present, the two main methods for veneer processing at home and abroad are rotary cutting and slicing, and the corresponding single plate is called rotary veneer 和刨切单板。旋切单板和刨切单板的厚度取决于各自机器的工艺技术参数。我国旋切单板的厚度大约为0．25～5．5mm，国外特殊用途旋切机旋切单板的厚度最厚可达12mm；刨切单板厚度的变化范围也很广，为0．2~lOmm。目前，采用旋切机制造的单板厚度大都在lmm以上，3mm以下，此范围的单板厚度均匀性较好，对于生产胶合板过程中的施胶等工序方便，不易透胶。旋切单板的幅面大，并且具有美丽的弦向花纹。现在，随着人们生活水平的提高，人们对生活质量的要求也越来越高。为了充分利用优质木材，目前多采用刨切的方法制取单板(亦称薄木)。刨切薄单板纹理美观、逼真，适于做拼花图案、胶合板和家具及建筑件的贴面等。 Cut veneer. The thickness of rotary veneer and planed veneer depends on the technological parameters of each machine. The thickness of China's rotary veneer is about 0.25 ~ 5.5mm. The thickness of rotary cutting veneer for foreign special purpose rotary cutting machine can reach 12mm, and the thickness of planed veneer varies widely, which is 0.2~lOmm. At present, the thickness of single plate produced by rotary cutting machine is mostly over LMM and less than 3mm. The thickness of single plate is better in this range. It is easy to apply glue in the process of producing plywood, and it is difficult to penetrate. The veneer is large in width and has beautiful chordal patterns. Now, with the improvement of people's living standard, people's demands for quality of life are getting higher and higher. In order to make full use of quality wood, we usually use the cutting method to produce veneer (also called veneer wood). Sliced veneer texture beautiful and vivid, suitable for parquet patterns, plywood and veneer furniture and building parts etc..

Due to the longitudinal slicing along the length direction of wood fiber, avoid horizontal veneer cracks caused by the transverse tensile strength of veneer veneer is high, there is almost no crack and surface crack back, not only uniform thickness, and smooth degree 好，不需砂光即可直接高档装饰贴面，从而提高了单板的强度和表面质量。③与锯切、旋切单板相比，刨切单板厚度更易达到0．2mm以下，便于向微木发展，可更有效地利用珍贵稀有木材，扩大珍贵优质 The utility model has the advantages that the decorative veneer can be directly decorated without sanding, thereby improving the strength and the surface quality of the veneer. The sawing, veneer, veneer thickness is more likely to 0.2mm the following, in order to micro wood development, can make effective use of rare wood, expand the precious quality |
