摘　　要：分析了最小量润滑(MQL)切削中供液方位、供液距离等因素对切削液渗透能力的影响。在SB-CNC超精密数控机床上进行了MQL车削45号钢试验,通过对切削力、表面粗糙度和切屑形态的研究表明:喷嘴位于主后刀面且距刀尖20 mm处供应较大量的切削液能达到良好的切削效果。The permeability of cutting fluids influences cutting effect directly. The main influential factors of cutting fluid penetration in minimum quantity lubrication （MQL） such as nozzle position, spray parameters were analyzed theoretically with spray and fluid mechanics. Based on turning 45 steel tests on CNC super precision machine tool, the cutting effect such as cutting force, surface roughness and chip shape were studied. Theory and tests results show that supplying more cutting fluids from main tool flank at proper position （20 mm from cutting point） can get better cutting effect： low cutting force, low surface roughness and easy treated chip.
