如何提高鋁制外殼的加工效率?

2023-04-05 09:02:11

  制外殼是鋁制品的常見加工方式之一,具有良好的機(jī)械性能和耐腐蝕性。鋁制外殼的加工效率很低,由于鋁的強(qiáng)度較弱,切削力大,刀具磨損快,刀具更換頻繁等原因。鋁制品切削效率提高的方法大致有以下幾種:

  一、增加切削速度。鋁的切削速度要遠(yuǎn)遠(yuǎn)低于鋼材的切削速度。鋼材的切削速度為20~25m/min,鋁的切削速度為8~12m/min。要使鋁的切削效率顯著提高,應(yīng)盡量增加切削速度。但是,隨著切削速度的提高,切削熱產(chǎn)生量也會(huì)相應(yīng)增加,切削溫度會(huì)升高,導(dǎo)致刀具磨損快,切削速度難以繼續(xù)提高。因此,切削速度提高過(guò)快會(huì)導(dǎo)致刀具磨損加速,切削效率降低。

  二、增加一個(gè)切削刀具。鋁切削速度快,切削熱產(chǎn)生大,刀具磨損快。為了減少刀具磨損,在相同的切削條件下,鋁制品加工應(yīng)適當(dāng)增加一把切削刀具,充分利用刀具的切削能力,并適當(dāng)減少切削速度。

  三、增加切削液的噴水量。鋁切削過(guò)程產(chǎn)生大量熱量,刀具磨損快。切削液具有切削熱的冷卻作用,增加噴水量可以有效地減少刀具磨損,提高切削效率。

  四、提高切削刀具的硬度。鋁切削時(shí)刀具磨損快,刀具硬度越高,磨損越小。如果條件允許,可以使用高硬度的刀具。

  五、增加切削劑的劑量。切削劑具有潤(rùn)滑作用,能夠有效地減少刀具磨損,提高切削效率。但是,切削劑的使用量不能過(guò)大,否則會(huì)影響切削精度。

  六、均勻鋁板。不均勻的鋁板容易使刀具磨損,降低切削效率。要保證鋁板的表面光滑,有利于刀具的使用。

  七、減少切削深度。鋁切削時(shí)刀具易磨損,為了減少刀具磨損,切削深度應(yīng)適當(dāng)減小。

  八、使用耐磨損的刀具。目前市場(chǎng)上出現(xiàn)了一種新型的耐磨損刀具,它具有較強(qiáng)的耐磨損性和耐腐蝕性,與傳統(tǒng)的刀具相比,具有明顯的優(yōu)勢(shì),可以顯著提高切削效率。

  如何提高鋁制外殼的加工效率?可以通過(guò)以上方法來(lái)提高鋁制品的切削效率。這些方法都有一定的經(jīng)驗(yàn)依據(jù),只要在實(shí)際加工中積累了一定的經(jīng)驗(yàn),就能夠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
