摘要
纳米流体微量润滑是一种新型的微量润滑增效技术,为探究其应用于难加工材料GH4169镍基高温合金时刀具磨损的变化规律,分别在干切削、微量润滑和纳米流体微量润滑三种条件下进行GH4169镍基高温合金车削加工试验,比较其切削力、切削温度以及刀具磨损的差异。通过切削试验发现,纳米流体微量润滑技术能够有效降低切削加工过程中的切削力、切削温度以及刀具的磨损程度,相比于干切削加工,纳米流体微量润滑条件下的切削力、切削温度和刀具的磨损程度分别降低21.9%,24.7%,15.9%。
Nano-fluid micro-lubrication is a new kind of micro-lubrication enhancement technology.In order to explore the changing rule of tool wear when nano-fluid micro-lubrication is applied to Ni base superalloy GH4169,the turning experiments of Ni base superalloy GH4169 are carried out under the three machining conditions of dry cutting,micro-lubrication and nano-fluid micro-lubrication respectively.The difference of cutting force,cutting temperature and tool wear is compared.It is found that nano-fluid micro-lubrication technology can effectively reduce the cutting force,cutting temperature and tool wear in the process of cutting.Compared with dry cutting,the cutting force,cutting temperature and tool wear are reduced by 21.9%,24.7% and 15.9% respectively under nano-fluid micro-lubrication condition.This technology can not only reduce cutting force and cutting temperature,but also reduce tool wear and prolong tool life.
