合金锯片的一些基本知识以及锯片的发展趋势  Some basic knowledge of alloy saw blade and the development trend of saw blade

　　合金锯片是我们都很熟悉的一个产品，因为这毕竟我们在生活中能经常看到这个东西，所以知名度也就大了很多。今天就来跟大家聊合金锯片的一些简单知识。希望能让大家更了解合金锯片。高速工具钢具有良好淬透性，硬度及刚性强，耐热变形少，属超高强度钢，热塑性稳定适宜制造高档超薄锯片。适用于开料和横锯各种软、硬实木型材和密度板、多层板、刨花板等。锯片直径小，切削速度相对比较低；锯片直径大对锯片和锯切设备要求就要高，同时锯切效率也高。细颗粒、超细颗粒硬质合金材料是发展方向；纳米涂层、梯度结构涂层及全新结构涂层将大幅度提高锯片使用性能；物理涂层（PVD）的应用继续增多。平齿锯口较粗糙，切削速度较慢，修磨简单。从单纯的锯片生产、供应，扩展至新切削工艺的开发及相应成套技术和解决方案的开发，为用户提供全面的技术支持和服务。后角是锯齿与已加工表面的之间的夹角，其作用是防止锯齿与已加工表面发生摩擦，后角越大则摩擦越小，加工的产品越光洁。

　　因为刀具寿命的长短、效率的高低不仅仅取决于刀具本身的质量，更重要的是合理应用，即只有在不同的加工条件下采用不同品种的刀具以及不同的加工参数，才能达到效果。齿数的选择，锯齿的齿数，一般来说齿数越多，在单位时间内切削的刃口越多，切削性能越好，在这里钨钢钻头回收也就的挺火爆了。切削齿数多需用硬质合金数量多，锯片的价格就高，但锯齿过密，齿间的容屑量变小，等闲引起锯片发热；另外锯齿过多，当进给量配合不当的话，每齿的削量很少，会加剧刃口与工件的磨擦，影响刀刃的使用寿命。选择锯片厚度时应从锯片工作的稳定性以及锯切的材料去考虑。锯齿的角度影响着切削的性能效果。切削技术快速发展。前角越大锯齿切削锐度越好，锯切越轻便，推料越省力。由于钨钴类的硬质合金抗冲击性较好，在木材加工行业中使用更为广泛。梯平齿是梯形齿和平齿的组合，修磨比较复杂，锯切时可减少贴面崩裂现象，适用于各种单双贴面人造板、防火板的锯切。通常齿间距在15-25mm，应根据锯切的材料选择合理的齿数。左右齿运用广泛，切削速度快，修磨相对简单。对切削影响很大的是前角γ、后角α、楔角β。主要用于普通木材的锯切，成本较低，多用于直径较小的铝用锯片，以保持切削时减少粘连，或用于开槽锯片以保持槽底平整。前角γ是锯齿的切入角，前角越大切削越轻快，前角一般在10-15℃之间。硬质合金材料及涂层应用增多。为刀具制造经济材料如T8A、T10A、T12A等。一般被加工材料材质较软时，选较大的前角，反之则选较小的前角。陶瓷、金属陶瓷、氮化硅陶瓷、PCBN、PCD等锯片材料的韧性进一步增强，应用场合日趋增多。

　　楔角是由前角和后角派生出来的。锯片制造商角色转变。倒梯齿常用于裁板锯底槽锯片中，在锯切双贴面的人造板时，槽锯调整厚度完成底面的开槽加工，再由主锯完成板材的锯切加工，以防止锯口出现崩边现象。有些特殊用途的材料要求的厚度也是特定的，应该按设备要求使用，如开槽锯片、划线锯片等。但楔角不能过小，它起着保持据齿的强度、散热性、耐用度的作用。装有防反弹力保护齿的左右齿即为燕尾齿，适用于纵向切割各种有树节的板材；带有负前角的左右齿锯片由于锯齿锋利、锯切质量好，通常用于贴面板的锯切。硬质合金种类的选择,硬质合金常用的种类有钨钴类（代号YG）、钨钛类（代号YT）。锯片研发更具针对性。面对日益增多的难加工材料，锯片行业必须改进锯片材料、研发新的锯片材料和更合理的锯片结构。锯片制造商研发的重点不再是通用品牌和通用结构。前角主要影响锯切木屑所消耗的力。锯齿角度的选择，锯齿部分的角度参数比较复杂，也专业，而正确选择锯片的角度参数是决定锯切质量的关键。信息化程度提高，锯片制造企业合作增强，市场竞争加剧。厚度的选择,锯片的厚度从理论上我们希望锯片越薄越好，锯缝实际上是一种消耗。锯片的外径根据不同的圆锯机机型选择使用直径相符的锯片。合金锯片基体的材料和制造锯片的工艺决定了锯片的厚度，厚度过薄，锯片工作时等闲晃动，影响切削的效果。锯齿的角度就是锯齿在切削时的位置。

　　而知道和了解在何种加工状态下应该采用何种类型的刀具，并将其开发和制造出来并能正确使用，就组成了企业应用技术的核心标准件的直径有：110MM(4寸)、150MM(6寸)、180MM(7寸)、200MM(8寸)、230MM(9寸)、250MM(10寸)、300MM(12寸)、350MM(14寸)、400MM(16寸)、450MM(18寸)、500MM(20寸)等，精密裁板锯的底槽锯片多设计为120MM。齿形的示例图片如下：左右齿形交替齿.梯平齿梯平齿,燕尾齿防反弹燕尾齿,平齿、倒梯齿其他齿形,综上所述，锯切实木、刨花板、中密板应选左右齿，能锐利地将木纤维组织割断，切口平滑；为了保持槽底平整的开槽，则用平齿齿形或者用左右平组合齿；锯切贴面板、防火板一般选择梯平齿，电脑开料锯由于锯切切率大，用的合金锯片直径和厚度都比较大，直径在350-450mm左右，厚度在4.0-4.8mm之间，多数采用梯平齿，以减少崩边、锯痕。铝用锯片为了防止粘连也多用梯平齿的齿数较多的锯片。主要的角度参数是前角、后角、楔角。合金工具钢与碳素工具钢相比，耐热性，耐磨性好，处理性能较好，耐热变形温度在300℃-400℃适宜制造高档合金圆锯片。高速切削、硬切削、干切削继续快速发展，应用范围在迅速扩大。新型锯片材料应用增多。直径的选择锯片直径与所用的锯切设备以及锯切工件的厚度有关。根据制造业发展的需要，多功能复合锯片、高速高效锯片将成为锯片发展的主流。刀具应用技术与生产技术一起形成刀具产品的两个不可分割的重要方面。硬质合金锯片的后角一般取值15℃。品牌刀具企业更是非常重视刀具的应用技术。制造业的加工技术水平受锯片行业整体水平的影响较大，而制造业的发展也会促进锯片行业的发展。

　　木材加工中常用的型号为YG8-YG15，YG后面的数字表示钴含量的百分数，钴含量增加，合金的抗冲击韧性和抗弯强度有所提高，但硬度和耐磨性却有所下降，要根据实际情况加以选用。面对复杂多变的应用场合和加工条件，研发针对性更强的刀片及锯片。基体的选择，65Mn弹簧钢弹性及塑性好，材料经济,热处理淬透性好,其受热温度低,易变形可用于要求切削要求不高的锯片。锯片行业在数控机床已成为制造装备主流的今天，肩负着为制造业提供关键装备数控锯片的重任。前角γ、后角α、楔角β三者之和等于90℃。齿形的选择，常用的齿形有左右齿(交替齿)、平齿、梯平齿(高低齿)、倒梯形齿(倒锥形齿)、燕尾齿(驼峰齿)、以及并不久未几见的工业级的三左一右、左右左右平齿等。碳素工具钢含碳高导热率高,但受200℃-250℃温度时其硬度和耐磨性急剧下降，热处理变形大，淬透性差，回火时间长易开裂。我想看到这里大家应该明白了锯片的知识了，这些简单和基础的知识对于我们这些广大的读者都有点巨大的好处，可以说的上是常识吧。推荐广大读者继续阅读相关性文章金刚石锯片，锯片这个家族是很大的，我们这里就是专门给大家介绍了其中的一种，金刚石锯片。这里面把金刚石锯片的各个功能都介绍的非常细致，相信定是会给大家一点帮助的。

The alloy saw blade is one of the products we arefamiliar with, because we often see this thing in our life, so the popularityis much bigger. Today we are going to talk about the simple knowledge of thealloy saw blade. I hope we can get a better understanding of the alloy sawblades. High speed tool steels have good hardenability, hardness and rigidity,low heat resistance, and high strength steel, and it is suitable for high gradeultra-thin saw blade. It is suitable for all kinds of soft, hard wood profilesand density board, multi-layer board, particleboard, etc. The blade diameter issmall and the cutting speed is relatively low. Saw blade diameter is highrequirement for saw blade and sawing equipment, and the cutting efficiency isalso high. Fine grain and superfine cemented carbide materials are thedevelopment direction. Nanometer coating, gradient structure coating and newstructure coating will greatly improve the performance of saw blade. Theapplication of physical coatings (PVD) continues to increase. The flat toothsaw blade is rougher, the cutting speed is slower, the grinding is thesimplest. From simple saw blade production and supply, to the development ofnew cutting technology and the development of corresponding complete technologyand solution, provide users with comprehensive technical support and service.The rear Angle is the Angle between the sawtooth and the processed surface,which is used to prevent the friction between the sawtooth and the processedsurface. The larger the rear Angle is, the smaller the friction is, and themore polished the processed products are.

Because the length of the knives' service life andefficiency of height is determined by the quality of the cutting tool not just,more important is reasonable application, namely only under differentprocessing conditions by using different kinds of and different processingparameters, can achieve the best effect. The choice of tooth number, the numberof teeth, generally speaking, the more the number of teeth, the more cuttingedge, the better the cutting performance, the tungsten steel bit recycling isvery popular. The number of cutting teeth is more than the number of hardalloy, the price of the saw blade is high, but the sawtooth is too dense, andthe volume of the chip between the teeth is small, which causes the blade toheat up. In addition, there are too many serrations, and when the amount offeed is mismatched, the cutting of each tooth is very small, which canaggravate the friction between the cutting edge and the workpiece and affectthe service life of the blade. When selecting the blade thickness, thestability of the saw blade and the cutting material should be considered. Thejagged Angle affects the performance of the cutting. Rapid development ofcutting technology. The larger the rake, the better the sharpness, the lighterthe sawing, the less power it will be. Because of the good impact resistance oftungsten cobalt, it is more widely used in wood processing industry. It is acombination of trapezoid tooth and peace tooth, it is more complicated torepair, and it can reduce the surface crack when cutting. It is suitable forthe sawing of all kinds of single and double veneers and fire prevention board.Normally, the tooth spacing is between 15 and 25mm, and the appropriate numberof teeth should be selected according to the sawing material. It is the mostwidely used, the cutting speed is fast, the grinding is relatively simple. Themost influential factors for the cutting are the former Angle, the posteriorAngle and the wedge Angle. It is mainly used for the sawing of common wood, andthe cost is lower. It is mainly used for aluminum saw blade with smallerdiameter, so as to reduce the adhesion when cutting, or use for slotting sawblade to keep the bottom level of the groove. Former Angle gamma is jagged cutAngle, the larger the rake Angle cutting the brisk, rake Angle between 10 to 15℃ ingeneral. The application of hard alloy materials and coatings has beenincreased. Manufacturing economic materials such as T8A, T10A, T12A, etc.Generally, when the material is soft, choose the larger front Angle and viceversa. The toughness of ceramic, metal ceramic, silicon nitride ceramics, PCBN,PCD and other saw blades has been further enhanced, and the applicationsituation is increasing.

The wedge Angle is derived from the anterior horn andthe posterior horn. Saw blade manufacturer role change. Inverted ladder toothoften saw bottom groove used for saw blade, the cutting double cover ofman-made board, groove saw adjust the thickness to complete underside groovingprocessing, again by the main processing, complete plate cutting in order toprevent the curf appear side damage phenomenon. Some special-purpose materialsare required to be of specific thickness and should be used according to therequirements of the equipment, such as slotting saw blade, marking saw blade,etc. But the wedge Angle should not be too small, it will maintain thestrength, heat dissipation and durability of the tooth. The right and leftteeth of the protective gear teeth are the swallowtail teeth, which aresuitable for the longitudinal cutting of all kinds of wood sections. The rightand left teeth saw blade with negative front Angle is usually used for thesawing of the panel because of the sharp saw and good quality of sawing. Thechoice of hard alloy type has tungsten cobalt class (codendum YG) and tungstentitanium (YT). Saw blade development is more targeted. In the face ofincreasingly difficult materials, saw blade industry must improve saw bladematerial, develop new saw blade material and more reasonable saw bladestructure. The focus of the makers of saw blades is no longer a generic brandor a generic structure. The front Angle mainly affects the force consumed bysawing sawdust. The selection of sawtooth Angle, the Angle parameter of thesawtooth part is more complex and the most professional, and the correct choiceof the Angle parameter of the saw blade is the key to determine the quality ofsawing. The degree of informatization has been improved, and the cooperation ofsaw blade manufacturing enterprises has been enhanced, and the marketcompetition has intensified. Thickness of the selection, the thickness of thesaw blade from the theory we hope that the thinner the better, saws areactually a kind of consumption. The outside diameter of the saw blade isselected according to the different circular saw machine. The material of thealloy saw blade matrix and the process of making saw blade determines thethickness of the saw blade, the thickness is too thin, and the blade issloshing when working, which affects the cutting effect. The jagged Angle isthe position of the serrated in the cutting.

And know and understand in what condition should adoptwhat kind of cutting tool, and its development and manufacturing and properlyused, will form the core of enterprise application technology standarddiameter: 110 mm (4 inches), 150 mm (6 inches), 180 mm (7 inches), 200 mm (8inches), 230 mm (9 inches), 250 mm (10 inches), 300 mm (12 inches), 350 mm (14inches), 400 mm (16 inches), 450 mm (18 inches), 500 mm (20 inches), saw morethan at the bottom of the tank saw blade precision design of 120 mm. Around thetooth profile of the sample pictures are as follows: tooth tooth alternately.Ladder ladder flat tooth, dovetail the rebound dovetail tooth, tooth, invertedladder other tooth shape, above all, saw about real wood, particle board,Micronesia board should choose tooth, will can sharply cut wood fiberorganization, incision smooth; In order to keep the grooves in the bottom ofthe groove, the teeth with flat teeth or the left and right flat teeth areused. Cutting veneers, choice of fire prevention board general ladder flatteeth, computer cutting saw, because of the large saw long rate of alloy sawblade diameter and thickness is bigger, 350-450 - mm in diameter, thicknessbetween 4.0 4.8 mm, most based on ladder flat teeth, to reduce the collapseedge, kerf. Aluminum saw blade is used to prevent the adhesion of the teethwith more teeth. The main Angle parameters are front Angle, rear Angle andwedge Angle. Alloy tool steel compared with carbon tool steel, heat resistance,good wear resistance, good processing performance, thermal deformationtemperature at 300 ℃ to 400 ℃ is suitable formanufacturing high-grade alloy circular saw blade. High-speed cutting, hardcutting and dry cutting continue to develop rapidly, and the application scopeis expanding rapidly. The application of new saw blades has been increased. Thediameter of the saw blade is related to the cutting equipment used and thethickness of the sawing workpiece. According to the needs of manufacturingindustry, multi-functional composite saw blades and high-speed high-efficiencysaw blades will become the mainstream of the development of saw blades. Toolapplication technology and production technology to form the two inseparableimportant aspects of tool products. Carbide saw blade Angle after the generalvalues of 15 ℃. Brand cutting tool enterprises attachgreat importance to tool application technology. The processing technology ofmanufacturing industry is greatly influenced by the overall level of sawbladeindustry, and the development of manufacturing industry will also promote thedevelopment of sawblade industry.

Modelis commonly used in wood processing of YG8 - YG15, YG behind the digitalrepresentation of the percentage of cobalt content, the cobalt contentincreased, the alloy impact toughness and bending strength increased, but thehardness and wear resistance has declined, according to the actual situation tochoose them. In the face of complex and changeable application situation andprocessing conditions, the development of more targeted blade and saw blade.The selection of the matrix, 65Mn spring steel elastic and plastic good,material economy, heat treatment and hardenability good, its heatingtemperature is low, easy deformation can be used to require the cutting demandnot high saw blade. The saw blade industry has become the mainstream ofmanufacturing equipment in the CNC machine tool. Wedge Angle between before andafter the Angle alpha, beta is equal to the sum of 90 ℃. Tooth profile, the choice of commonly usedtooth has about tooth (teeth) alternately, flat tooth, ladder flat teeth (highand low gear), inverted trapezoidal tooth (taper teeth), dovetail tooth (tooth)hump, and industrial-grade matter shortly and see about three left the right,left and right sides of the flat teeth, etc. Carbon tool steel containing highcarbon high thermal conductivity, but the temperature of 200 ℃ to 250 ℃ when the sharp decline in its hardness and wearresistance, heat treatment deformation is big, poor hardenability, temperingtime easy to crack. I want to see here that you should understand the knowledgeof the saw blade. These simple and basic knowledge are of great benefit to ourvast readers, so it is common sense to say. It is recommended that the readerscontinue to read the relevant article diamond saw blade, the family of sawblade is very large, we are here to introduce one of them, diamond saw blade.The various functions of diamond saw blade are very detailed, and I believe itwill help you a little bit.
