制外殼是鋁制品的常見加工方式之一，具有良好的機械性能和耐腐蝕性。鋁制外殼的加工效率很低，由于鋁(lv)的(de)強度較弱(ruo)，切(qie)削(xue)力大，刀具磨損快(kuai)，刀具更換頻繁等原因(yin)。鋁(lv)制(zhi)品切(qie)削(xue)效率提(ti)高的(de)方法大致有以下幾種：

　　一、增加切(qie)(qie)(qie)削(xue)(xue)(xue)速(su)(su)度(du)。鋁(lv)的(de)切(qie)(qie)(qie)削(xue)(xue)(xue)速(su)(su)度(du)要(yao)遠遠低(di)于鋼材(cai)的(de)切(qie)(qie)(qie)削(xue)(xue)(xue)速(su)(su)度(du)。鋼材(cai)的(de)切(qie)(qie)(qie)削(xue)(xue)(xue)速(su)(su)度(du)為20~25m/min，鋁(lv)的(de)切(qie)(qie)(qie)削(xue)(xue)(xue)速(su)(su)度(du)為8~12m/min。要(yao)使鋁(lv)的(de)切(qie)(qie)(qie)削(xue)(xue)(xue)效率顯著提(ti)高(gao)，應盡量增加切(qie)(qie)(qie)削(xue)(xue)(xue)速(su)(su)度(du)。但是，隨著切(qie)(qie)(qie)削(xue)(xue)(xue)速(su)(su)度(du)的(de)提(ti)高(gao)，切(qie)(qie)(qie)削(xue)(xue)(xue)熱產(chan)生量也會相(xiang)應增加，切(qie)(qie)(qie)削(xue)(xue)(xue)溫度(du)會升(sheng)高(gao)，導(dao)致(zhi)刀(dao)具磨損快，切(qie)(qie)(qie)削(xue)(xue)(xue)速(su)(su)度(du)難以繼續提(ti)高(gao)。因此，切(qie)(qie)(qie)削(xue)(xue)(xue)速(su)(su)度(du)提(ti)高(gao)過快會導(dao)致(zhi)刀(dao)具磨損加速(su)(su)，切(qie)(qie)(qie)削(xue)(xue)(xue)效率降(jiang)低(di)。

　　二(er)、增加(jia)一(yi)個切削(xue)(xue)刀(dao)具(ju)。鋁(lv)切削(xue)(xue)速度快(kuai)(kuai)，切削(xue)(xue)熱產生大(da)，刀(dao)具(ju)磨損(sun)快(kuai)(kuai)。為了減少刀(dao)具(ju)磨損(sun)，在相同的切削(xue)(xue)條件下，鋁(lv)制品加(jia)工應適(shi)當(dang)增加(jia)一(yi)把切削(xue)(xue)刀(dao)具(ju)，充(chong)分利(li)用刀(dao)具(ju)的切削(xue)(xue)能力，并適(shi)當(dang)減少切削(xue)(xue)速度。

　　三(san)、增加切(qie)削(xue)(xue)(xue)液(ye)的(de)噴水量(liang)。鋁(lv)切(qie)削(xue)(xue)(xue)過程產(chan)生大(da)量(liang)熱量(liang)，刀具(ju)(ju)(ju)磨損(sun)快。切(qie)削(xue)(xue)(xue)液(ye)具(ju)(ju)(ju)有切(qie)削(xue)(xue)(xue)熱的(de)冷卻(que)作用，增加噴水量(liang)可以有效地減(jian)少刀具(ju)(ju)(ju)磨損(sun)，提高切(qie)削(xue)(xue)(xue)效率。

　　四、提高(gao)切削刀(dao)具的硬度。鋁切削時刀(dao)具磨損快(kuai)，刀(dao)具硬度越(yue)高(gao)，磨損越(yue)小。如果條件允許，可以使用(yong)高(gao)硬度的刀(dao)具。

　　五、增加切削劑的劑量。切削劑具有潤滑作用，能夠有(you)效(xiao)地減少(shao)刀具磨損(sun)，提高切(qie)削(xue)效(xiao)率。但(dan)是，切(qie)削(xue)劑(ji)的使(shi)用量不能(neng)過大，否則會影響切(qie)削(xue)精度。

　　六、均勻鋁(lv)板(ban)(ban)(ban)。不均勻的鋁(lv)板(ban)(ban)(ban)容易使刀具(ju)磨損，降低(di)切(qie)削效率(lv)。要保證鋁(lv)板(ban)(ban)(ban)的表面光滑，有利于刀具(ju)的使用。

　　七、減(jian)少(shao)切削深度。鋁切削時刀具(ju)易磨損(sun)，為(wei)了減(jian)少(shao)刀具(ju)磨損(sun)，切削深度應(ying)適當減(jian)小。

　　八、使用(yong)耐(nai)磨(mo)損(sun)的(de)(de)刀(dao)(dao)具(ju)。目前市場上出現了一種新型的(de)(de)耐(nai)磨(mo)損(sun)刀(dao)(dao)具(ju)，它具(ju)有較強的(de)(de)耐(nai)磨(mo)損(sun)性(xing)和耐(nai)腐蝕性(xing)，與傳統的(de)(de)刀(dao)(dao)具(ju)相比，具(ju)有明顯(xian)的(de)(de)優勢，可以(yi)顯(xian)著提高切削(xue)效率(lv)。

　　如何提(ti)(ti)高鋁制外殼的(de)(de)加工效(xiao)率?可以(yi)通過以(yi)上方(fang)法來提(ti)(ti)高鋁制品的(de)(de)切(qie)削效(xiao)率。這些方(fang)法都有一定的(de)(de)經(jing)驗(yan)依據，只要在(zai)實際加工中積累了一定的(de)(de)經(jing)驗(yan)，就能夠有效(xiao)地提(ti)(ti)高切(qie)削效(xiao)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
