隨著機械產品制作精度的不斷提高，對鋁板加工的要求也越來越高，就拿鋁板鉆孔來說吧，與十年前相比以提高了上百倍。鋁板鉆孔后孔徑超標成為了困擾越來越多鋁板廠家的一個難題，如果您還被這個問題困擾，今天就讓我們的專家給大家支個招，為您排憂解難。
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.
，因為鋁的材質比較軟，粘性比較大，用螺旋絲錐；
First of all, because the material of aluminum is soft and sticky, screw taps are used;

其次，一般的鉆孔機，力度比較大，若有鋁削的會直接攻下去，會導致爛牙或斷絲錐，孔徑增大的問題；
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，也與操作有一定的關系，若是手稍微抖動，就會出現這種情況，畢竟M3的絲錐很細,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，找一個氣動的鉆孔機，裝絲錐的筒夾好選擇帶有扭力保護的，萬一出現問題，它就會打滑，保證不斷絲錐，不爛牙；
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;
再然后孔打的好標準,鉆孔時要使用專門的鉆孔油
Then, the standard of drilling should be made, and special drilling oil should be used when drilling
鋁板鉆孔注意事項
Precautions for drilling aluminum plate
在鉆孔的過程中，冷卻液要不停的對準夾具，因為M3鋁材質相對較硬，在鉆孔的過程中熱量很大，冷卻液可以一定程度的降低溫度，使鉆頭的工作時間更長，避免鉆頭在鋁材質中逐漸的融合。
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.
