制外壳是铝制品的常见加工方式之一，具有良好的机械性能和耐腐蚀性。铝制外壳的加工效率很低，由于铝的强度较弱，切削力大，刀具磨损快，刀具更换频繁等原因。铝制品切削效率提高的方法大致有以下几种：

　　一、增加切削速度。铝的切削速度要远远低于钢材的切削速度。钢材的切削速度为20~25m/min，铝的切削速度为8~12m/min。要使铝的切削效率显著提高，应尽量增加切削速度。但是，随着切削速度的提高，切削热产生量也会相应增加，切削温度会升高，导致刀具磨损快，切削速度难以继续提高。因此，切削速度提高过快会导致刀具磨损加速，切削效率降低。

　　二、增加一个切削刀具。铝切削速度快，切削热产生大，刀具磨损快。为了减少刀具磨损，在相同的切削条件下，铝制品加工应适当增加一把切削刀具，充分利用刀具的切削能力，并适当减少切削速度。

　　三、增加切削液的喷水量。铝切削过程产生大量热量，刀具磨损快。切削液具有切削热的冷却作用，增加喷水量可以有效地减少刀具磨损，提高切削效率。

　　四、提高切削刀具的硬度。铝切削时刀具磨损快，刀具硬度越高，磨损越小。如果条件允许，可以使用高硬度的刀具。

　　五、增加切削剂的剂量。切削剂具有润滑作用，能够有效地减少刀具磨损，提高切削效率。但是，切削剂的使用量不能过大，否则会影响切削精度。

　　六、均匀铝板。不均匀的铝板容易使刀具磨损，降低切削效率。要保证铝板的表面光滑，有利于刀具的使用。

　　七、减少切削深度。铝切削时刀具易磨损，为了减少刀具磨损，切削深度应适当减小。

　　八、使用耐磨损的刀具。目前市场上出现了一种新型的耐磨损刀具，它具有较强的耐磨损性和耐腐蚀性，与传统的刀具相比，具有明显的优势，可以显著提高切削效率。

　　如何提高铝制外壳的加工效率?可以通过以上方法来提高铝制品的切削效率。这些方法都有一定的经验依据，只要在实际加工中积累了一定的经验，就能够有效地提高切削效率。

　　Cutting shells is one of the common processing methods of aluminum products, with good mechanical properties and corrosion resistance. The processing efficiency of aluminum shells is very low. Due to the weak strength of aluminum, the cutting force is large, the tool wear is fast, and the tool change is frequent. There are several ways to improve the cutting efficiency of aluminum products:

　　1. Increase the cutting speed. The cutting speed of aluminum is much lower than that of steel. The cutting speed of steel is 20-25m/min, and the cutting speed of aluminum is 8-12m/min. In order to significantly improve the cutting efficiency of aluminum, the cutting speed should be increased as much as possible. However, with the increase of cutting speed, the cutting heat produced will also increase correspondingly, and the cutting temperature will rise, resulting in accelerated tool wear and difficult to continue to increase cutting speed. Therefore, too high cutting speed will lead to accelerated tool wear and reduced cutting efficiency.

　　2. Add an extra cutting tool. The cutting speed of aluminum is fast, the cutting heat is large, and the tool wear is fast. In order to reduce tool wear, under the same cutting conditions, an extra cutting tool should be added to the processing of aluminum products, so as to make full use of the cutting ability of the tool, and to reduce the cutting speed appropriately.

　　3, increase the amount of cutting fluid. A large amount of heat is generated during aluminum cutting, and the tool wear is fast. Cutting fluid has the function of cooling the cutting heat, and increasing the water injection quantity can effectively reduce the tool wear and improve the cutting efficiency.

　　4. Increase the hardness of the cutting tool. The cutting tool wears quickly when cutting aluminum, and the tool hardness is higher, the wear is smaller. If conditions permit, high hardness tools can be used.

　　5. Increase the dosage of cutting agent. The cutting agent has the function of lubrication, which can effectively reduce the tool wear and improve the cutting efficiency. However
