MQL_微量潤滑系統
來源:admin   時間::2020-04-22     點擊次:


 MQL微量潤滑也叫做小量潤滑,英文為Minimal Quantity Lubrication(MQL)是一種金屬加工的潤滑方式,即準干式切削。

 是將壓縮氣體(空氣、氮氣、二氧化碳等)與極微量的潤滑油混合汽化后,形成微米級的液滴,噴射到加工區進行有效潤滑的一種切削加工方法。

 切削液的用量一般僅為0.03-0.2L/h(傳統濕法切削的用量為20-100L/min),可有效減少刀具與工件、刀具與切屑之間的摩擦,防止粘結,延長刀具壽命,提供加工表面質量。


微量潤滑MQL技術融合了干式切削與傳統濕式切削兩者的點:

一方面,MQL將切削液的用量降低到微量的程度,不僅顯著降低切削液的使用成本,而且通過使用自然降解性高的合成酯類作為潤滑劑,降低切削液對環境和人體的危害;
 
另一方面,與干式切削相比,MQL由于引入了冷卻潤滑介質,使得切削過程的冷卻潤滑條件改善,刀具、工件和切屑之間的磨損減小,有助于降低切削力、切削溫度和刀具的磨損。
