铝箔后加工是一个企业至关重要的环节，关乎一个铝企成品率与企业赢利点。成品率越高，企业赢利点相对就越大。当然，成品率是每一个环节都要把控，规范化操作，还需要精良的设备与责任心强的、职工。    设备与操作规范我都不懂，不敢指手画脚，我只能在分切用刀上依据实践剖析一下。下面我讲讲分切为什么会发生翘边、多边、掉粉。翘边、多边、掉粉问题除去资料本身与设备问题，大部分都与刀片相关。
Aluminum foil post-processing is an important part of an enterprise, which is related to the yield and profit point of an aluminum enterprise. The higher the yield is, the greater the profit point is. Of course, the finished product rate should be controlled in every link, standardized operation, and also requires sophisticated equipment and responsible leadership and staff. I don't know the equipment and operation specifications. I dare not point my finger at them. I can only analyze them on the cutting knife according to practice. Next, I'll talk about why slicing happens, such as edge warping, multilateral and powder dropping. The problems of edge warping, multilateral and powder dropping are mostly related to blades, except for the data itself and equipment problems.
通常铝箔分切主要有两种刀片。一种是圆刀片，一种是片式划刀片也称剃刀。剃刀片是固定一个点位，以资料收卷被迫切开、划开。铝箔为自动分切，速度越快，刀片的阻力相对越小。越慢与之相反。刀片的厚薄与阻力相对应的。刀片越厚，阻力越大。越薄与之相反。由于剃刀片是划切固定不动的，刀口与箔、薄资料触摸时，切点简单呈现疲劳发热，所以过一段时间后就会刀口不尖利，刀钝就会呈现撕裂现象，呈现掉粉毛边在所难免。当然，这些与分切视点也有关系。选用好的剃刀片是处理这些问题的，陶瓷刀片应该是。
Usually there are two kinds of blades for cutting aluminium foil. One is round blade, the other is blade blade, also known as razor. The razor blade is fixed at a point, and is forced to cut and cut with data winding. Aluminum foil is cut automatically. The faster the speed, the smaller the resistance of the blade. The slower it is, the opposite is true. The thickness of the blade corresponds to the resistance. The thicker the blade, the greater the resistance. Thinner is the opposite. Because the razor blade is cut and fixed, when the blade touches foil and thin data, the cutting point simply presents fatigue and fever, so after a period of time, the blade will not be sharp, the knife will be blunt, showing tearing phenomenon, showing that the powdered edge is unavoidable. Of course, these are also related to the sharding perspective. Choosing a good razor blade is the first choice to deal with these problems. Ceramic blade should be the first choice.
现在一切铝箔企业都想加工高附加值的电池箔，但电池箔验收规范堪称严苛。代表性锂电池企业中像：比亚迪、ATL、A123电芯企业，对铝箔的验收规范堪称严苛。对箔要求极高，并且对宽幅、粉尘、翘边也算是严苛中的严苛。所以关于产值并不高的电池箔企业，后加工分
Now all aluminium foil enterprises want to process high value-added battery foil, but the acceptance criteria for battery foil can be rigorous. Among the representative lithium battery enterprises, such as BYD, ATL and A123, the acceptance criteria for aluminium foil are rigorous. The requirement for foil is very high, and the width, dust and edge warping are also rigorous. So for battery foil enterprises with low output value, post-processing points
［陶瓷与钢刀片的区分］在高速分切中，钢刀片散热系数差，分切速度越高，摩擦系数就越大，发生热量就会越多，截留在钢刀片的热量就越多。分切过程中箔与刀片磨擦会发生热量，一部分热量跟着收卷已在常温下散去，而另一部分热量就留在了钢刀片上，并且是累计热量，分切时间越长、速度越高，留在刀片上的热量就会越多。这样刀片又把热量传导到箔上，就形成了对箔传热，由于这时候刀片已呈现高温再与箔触摸就会发生粉尘黏刀，使刀片使去尖利度，形成掉粉、翘边状况。同时刀片过热又会使刀片失掉了原有的硬度，而失掉耐用性与尖利度，从而发生掉粉、荷叶边等。切成品率，至关重要。

[Differentiation between ceramic and steel blade] In high-speed cutting, the heat dissipation coefficient of steel blade is poor. The higher the cutting speed, the greater the friction coefficient, the more heat generated, and the more heat retained in the steel blade. During the cutting process, the friction between foil and blade will generate heat. Some of the heat dissipates with the winding at room temperature, while the other part of the heat remains on the steel blade and is the accumulated heat. The longer the cutting time and the higher the speed, the more heat left on the blade. In this way, the blade transfers heat to the foil, which forms heat transfer to the foil. Because the blade has high temperature and then touches the foil, dust sticks to the blade, which makes the blade sharpen and form the condition of powder dropping and edge warping. At the same time, the blade will lose its original hardness, durability and sharpness, resulting in powder loss, lotus edge and so on. Cutting rate is very important.
［铝箔圆刀片的两种分切方法］  圆刀片分切有一部分是铝箔自动分切，也就是圆刀片被箔资料收卷带动旋转，与剃刀片是同样的方法，仅仅有更多刃口的与资料触摸。这种方法由于刀片本身是被迫的，受资料的速度影响，触摸点、刀口是下压方法。资料收卷是有跳动的，由于刀片本身没有动力，收卷的动摇易出翘边。
[Two kinds of cutting methods of aluminium foil round blade] Round blade cutting is part of automatic cutting of aluminium foil, that is, round blade is rotated by foil data winding, the same method as razor blade, only more edges and data touch. This method is forced by the blade itself and affected by the speed of data. Touch points and knife edges are downward pressing methods. Data winding is jumpy, because the blade itself has no power, the winding shake easily out of the warp edge.
圆刀自动分切，这是现在较通用的方法。圆刀自动分切有两种，一种是同轴滚动，一种是独臂式电机驱动。个人更看好独臂式驱动，这种可以依据资料厚度不同，调节刀片转速。  圆刀常规状况以上下刀合作分切，而咱们通常看到的是蝶形上刀，为什么咱们要用蝶形上刀呢？这是从日韩传过来的，由于平行度不行，用蝶形刀片可以补偿这方面的缺乏，咱们通常都要把蝶形上刀给压贴合在下刀上，就是怕平行度不行，切不出好的产品。这点请大家注意：德国人，不必蝶形碗状刀片。他们的刀片，都是一个平面，由于他们的刀片平行度误差不超过0.5um。但通常德国分切刀片厚度都会挑选在2mm以上。由于刀片越薄，平行度公差越难控制。但厚度越厚，阻力越大，越简单呈现翘边、压痕、掉粉状况。个人，更倾向于薄刀片，以为刀片越薄，切出的
Round knife automatic cutting, this is the most common method now. There are two kinds of automatic cutter slitting, one is coaxial rolling, the other is driven by one-arm motor. Individuals prefer one-arm drive, which can adjust blade speed according to different data thickness. Round knife is usually cut with top and bottom knives, but what we usually see is Butterfly Top knife. Why should we use Butterfly Top knife? This is from Japan and Korea, because parallelism is not good, butterfly blade can compensate for this lack, we usually have to press the butterfly top knife on the lower knife, is afraid that parallelism is not good, can not cut good products. This point, please note: Germans do not need butterfly bowl blades. Their blades are all flat, because their parallelism error is less than 0.5 um. But usually the thickness of the cutting blade in Germany is more than 2 mm. The thinner the blade, the more difficult it is to control the parallelism tolerance. However, the thicker the thickness is, the greater the resistance is, and the simpler the situation of warping, indentation and powder dropping is. Individuals prefer thin blades, thinking that the thinner the blade, the more cut out.
