合金锯片的一些基本知识bob200体育及锯片的发展趋势
2020年1月10日

合金锯片是我们都熟悉的产品,因为毕竟,我们经常在生活中看到这件事,所以受欢迎程度要​​大得多。让我谈谈今天对合金锯片的一些简单知识。bob200体育希望让每个人都了解有关合金锯片的更多信息。高速工具钢具有良好的淬透性,强硬和刚性,耐热变形较小。它属于超高强度钢。它是热塑性稳定的,适用于制造高端超薄锯片。它适用于切割和横切各种柔软和硬实木型材和MDF,多层板,刨花板等。锯片直径小,切割速度相对较低;较大的锯片直径需要对锯片和锯切设备的更高要求,并且锯切效率也很高。细粒度和超细粒化硬质合金材料是发展方向;纳米涂层,梯度结构涂层和新的结构涂层将大大提高锯片的性能; the application of physical coatings (PVD) continues to increase. The flat tooth saw is rough, the cutting speed is slow, and the grinding is the simplest. From the simple production and supply of saw blades to the development of new cutting processes and the development of corresponding sets of technologies and solutions, we provide users with comprehensive technical support and services. The relief angle is the angle between the sawtooth and the processed surface, and its role is to prevent friction between the sawtooth and the processed surface. The larger the relief angle, the smaller the friction, and the smoother the processed product.

因为刀具寿命的长度和效率不仅取决于工具本身的质量,更重要的是,合理的应用程序,也就是说,最好的结果只能通过使用不同类型的工具和不同的加工参数在不同处理条件下。。齿数的选择,锯齿的齿数,一般来说,齿数越多,单位时间内切削刃越多,切削性能就越好,这里钨钢钻头的回收比较受欢迎。如果切削齿的数量大,就需要大量的硬质合金,而锯片的价格也高,但是锯齿太密集,齿间的碎屑量就变小,锯片就会发热。此外,还有太多的牙齿。每颗齿的切削量小,会加剧切削刃与工件之间的摩擦,影响切削刃的使用寿命。在选择锯片厚度时,应考虑锯片工作的稳定性和要切割的材料。锯齿的角度影响切削性能。切削技术发展迅速。前角越大,锯齿切割的锐度越好,锯切越轻,推料越省力。由于钨钴基硬质合金具有更好的抗冲击性能,它们在木材加工工业中得到了更广泛的应用。 Trapezoidal teeth are a combination of trapezoidal teeth and flat teeth. The grinding is more complicated. It can reduce the veneer chipping when sawing. It is suitable for sawing of various single and double veneer artificial boards and fireproof boards. The tooth pitch is usually 15-25mm, and a reasonable number of teeth should be selected according to the material being sawed. Left and right teeth are most widely used, with fast cutting speed and relatively simple dressing. The greatest influence on cutting is the rake angle γ, the rake angle α, and the wedge angle β. It is mainly used for sawing of ordinary wood with low cost. It is mostly used for aluminum saw blades with smaller diameters to keep cuttings from cutting or to groove the saw blades to keep the groove bottom flat. The rake angle γ is the cutting angle of the saw tooth. The larger the rake angle is, the faster the cutting is. The rake angle is generally between 10-15 ° C. The use of hard alloy materials and coatings has increased. Manufacture of economic materials for tools such as T8A, T10A, T12A, etc. Generally, when the material of the material to be processed is soft, choose a larger rake angle, otherwise choose a smaller rake angle. The toughness of saw blade materials such as ceramics, cermets, silicon nitride ceramics, PCBN, PCD and the like is further enhanced, and applications are increasing.


楔角源自前角和后角。锯片制造商的作用发生了变化。倒梯齿通常用于面板锯底槽锯片。当锯切双面人工板时,槽锯调节厚度以完成底表面的凹槽,然后主锯完成板的锯切以防止锯切。折腾的折痕。一些专用材料需要特定的厚度,应按照设备要求使用,如开槽锯片,划线锯片等。但楔角不能太小,它起到了保持强度,散热的作用和牙齿的耐久性。左右齿配有防反弹力保护牙齿的燕尾齿,适用于纵向切割各种板;具有负耙角的左右牙齿锯片通常用于粘附,因为锋利的齿和良好的锯切质量面板切割。选择碳化物类型的选择。 The types commonly used in cemented carbide are tungsten-cobalt (code YG) and tungsten-titanium (code YT). Saw blade research and development is more targeted. Faced with an increasing number of difficult-to-machine materials, the saw blade industry must improve saw blade materials, develop new saw blade materials, and more rational saw blade structures. The focus of the blade manufacturer's research and development is no longer on generic brands and common structures. The rake angle mainly affects the force required to saw the sawdust. The choice of the saw tooth angle, the angle parameter of the saw tooth part is more complicated and the most professional, and the correct selection of the saw blade angle parameter is the key to determine the sawing quality. The degree of informatization has increased, cooperation between saw blade manufacturing companies has increased, and market competition has intensified. The choice of thickness, the thickness of the saw blade. Theoretically we hope that the thinner the saw blade, the better. The saw seam is actually a kind of consumption. The outer diameter of the saw blade is selected according to the different circular saw machine models. The material of the base material of the alloy saw blade and the process of manufacturing the saw blade determine the thickness of the saw blade. The thickness is too thin, and the saw blade will shake leisurely during work, affecting the cutting effect. The angle of the tooth is the position of the tooth during cutting.


并且了解和了解如何在处理状态下使用哪种类型的工具,开发和制造它并可以正确使用,弥补企业应用技术直径的核心标准部分是:110mm(4英寸),150mm(6英寸),180mm(7英寸),200mm(8英寸),230mm(9英寸),250mm(10英寸),300mm(12英寸),350mm(14英寸),400mm(16英寸),450mm(18英寸),500mm(20英寸)等,精密面板锯的底部槽叶片主要设计为120mm。牙齿轮廓的示例图片如下:左和右齿交替齿。梯形扁齿梯平齿,燕尾牙防反弹燕尾牙,扁齿,倒梯齿其他牙齿形状。总之,应选择锯实木,刨花板,中致密左右牙齿的左右齿,可急剧切割木纤维组织,切口平滑;为了保持凹槽底部平坦,使用扁平的齿牙或使用左右扁平齿;一般来说,梯子用于锯板和消防板扁平齿,由于切割速率大,合金锯片的直径和厚度相对较大。直径约为350-450mm,厚度在4.0-4.8mm之间。其中大多数都使用阶梯齿来减少碎裂。边缘,锯片。 In order to prevent sticking of aluminum saw blades, saw blades with a large number of steps are generally used. The most important angle parameters are rake angle, rake angle, and wedge angle. Compared with carbon tool steel, alloy tool steel has better heat resistance, abrasion resistance and better handling performance. The heat distortion temperature is suitable for manufacturing high-grade alloy circular saw blades at 300 ℃ -400 ℃. High-speed cutting, hard cutting, and dry cutting continue to develop rapidly, and the scope of application is rapidly expanding. New saw blade material applications are increasing. The diameter of the saw blade depends on the sawing equipment used and the thickness of the sawing workpiece. According to the needs of the development of the manufacturing industry, multifunctional composite saw blades and high-speed and efficient saw blades will become the mainstream of saw blade development. Tool application technology and production technology together form two inseparable important aspects of tool products. The back angle of cemented carbide saw blade is generally 15 ° C. Brand cutting tool companies attach great importance to the application technology of cutting tools. The level of manufacturing technology is greatly affected by the overall level of the saw blade industry, and the development of the manufacturing industry will also promote the development of the saw blade industry.


木材加工常用的型号为YG8-YG15。YG后面的数字表示钴含量的百分比。随着钴含量的增加,合金的冲击韧性和弯曲强度增加,但硬度和耐磨性降低。根据实际情况选择。面对复杂多变的应用和加工条件,我们开发了更具针对性的锯片和锯片。在基材的选择上,65Mn弹簧钢具有良好的弹性和可塑性,材料经济,热处理和淬炼性好,其加热温度低,易变形,可用于对锯片切割要求不高的锯片。在锯片行业中,数控机床已经成为制造设备的主流,用数控锯片担负着为制造业提供关键设备的重任。之和倾角γ,倾角α,和楔角β= 90°c .齿形的选择,常用的牙齿形状是左边和右边的牙齿(替代牙齿),平的牙齿,扁扁的牙齿牙齿(高、低),倒置的梯形齿(倒锥形牙齿),鸠尾牙(驼峰的牙齿),很快就看到了工业级的三左、一右、左右、左右扁平的牙齿。碳素工具钢含有高碳和高导热系数,但其硬度和耐磨性在经受200℃-250℃温度时急剧下降,热处理变形量大,淬炼性差,回火时间容易产生裂纹。 I want to see that everyone here should understand the knowledge of saw blades. These simple and basic knowledge have a great benefit to our readers. It can be said that it is common sense. The readers are recommended to continue to read the related article Diamond Saw Blades.
