在切削加工中冷却技术的应用具有重要作用,在某些操作中冷却技术甚至是不可或缺的.在切削过程中应用冷却剂可以延长刀具寿命和加工精度,降低切削温度、工件表面粗糙度及功率损耗,提高生产率.本文首先介绍了低温加工的特点和分类,而后阐述了低温加工工艺的现状,尤其是对工件、切屑的冷却、对刀具的冷却以及一些合金材料的机械加工性能进行了论述.最后,低温切削技术可以通过控制切削区的温度来降低磨损,在很大程度上延长刀具寿命,改善工件表面质量,因此,该技术已成为材料切削加工中最有利的方法之一.

The cooling applications in machining operations play a very important role and many operations cannot be carried out efficiently without cooling. Application of a coolant in a cutting process can increase tool life and dimensional accuracy, decrease cutting temperatures, surface roughness and the amount of power consumed in a metal cutting process and thus improve the productivity. In this review characteristics and classifications of cryogenic treatment is investigated. Subsequently, state of the art cryogenic machining, especially with cryogenic workpiece/chip cooling, cryogenic cutting tool cooling, and cryogenic machinability of some composite materials, is discussed. As a result, cryogenic cooling has been determined as one of the most favorable method for material cutting operations due to being capable of considerable improvement in tool life and surface finish through reduction in tool wear through control of machining temperature desirably at the cutting zone.
