随着机械产品制作精度的不断提高，对铝板加工的要求也越来越高，就拿铝板钻孔来说吧，与十年前相比以提高了上百倍。铝板钻孔后孔径超标成为了困扰越来越多铝板厂家的一个难题，如果您还被这个问题困扰，今天就让我们的专家给大家支个招，为您排忧解难。
With the continuous improvement of the manufacturing accuracy of mechanical products, the requirements for aluminum plate processing are also higher and higher. Take aluminum plate drilling for example, compared with ten years ago, it has increased by hundreds of times. If you are still troubled by this problem, today let our experts give you a move to solve your problems.
，因为铝的材质比较软，粘性比较大，用螺旋丝锥；
First of all, because the material of aluminum is soft and sticky, screw taps are used;

其次，一般的钻孔机，力度比较大，若有铝削的会直接攻下去，会导致烂牙或断丝锥，孔径增大的问题；
Secondly, the general drilling machine, the strength is relatively large, if there is aluminum cutting will directly attack down, will lead to tooth rot or broken tap, aperture increase problem;
再次，也与操作有一定的关系，若是手稍微抖动，就会出现这种情况，毕竟M3的丝锥很细,要格外注意操作；
Thirdly, it has something to do with the operation. If the hand shakes a little, this will happen. After all, the tap of M3 is very thin, so we should pay special attention to the operation;
然后，找一个气动的钻孔机，装丝锥的筒夹好选择带有扭力保护的，万一出现问题，它就会打滑，保证不断丝锥，不烂牙；
Then, find a pneumatic drilling machine, the best choice for the tap holder with torque protection, in case of problems, it will slip, to ensure constant tap, not tooth decay;
再然后孔打的好标准,钻孔时要使用专门的钻孔油
Then, the standard of drilling should be made, and special drilling oil should be used when drilling
铝板钻孔注意事项
Precautions for drilling aluminum plate
在钻孔的过程中，冷却液要不停的对准夹具，因为M3铝材质相对较硬，在钻孔的过程中热量很大，冷却液可以一定程度的降低温度，使钻头的工作时间更长，避免钻头在铝材质中逐渐的融合。
In the process of drilling, the coolant keeps aiming at the fixture. Because m3 aluminum material is relatively hard, there is a lot of heat in the process of drilling. The coolant can reduce the temperature to a certain extent, make the working time of the drill longer, and avoid the gradual fusion of the drill in the aluminum material.
