低温冷风纳米粒子微量润滑磨削轴承钢试验研究

摘要/Abstract

摘要： 低温纳米粒子微量润滑（Nano-CMQL）是将低温冷风技术与纳米粒子润滑油两者有效结合起来的一种高效绿色新型磨削加工润滑方法。采用60目陶瓷结合剂的氧化铝砂轮对GCr15淬硬轴承钢进行磨削试验，比较了常温干式、浇注式、低温冷风微量润滑(CMQL)以及Nano-CMQL四种工况在不同磨削参数下的法向磨削力、比磨削能、磨削温度、工件表面轮廓及粗糙度，结果表明，在基础磨削液中加入粒径为40 nm的MoS2固体颗粒制备出的Nano-CMQL磨削液能够有效地减小磨削加工过程中的法向磨削力并降低磨削温度，尤其在高速、大磨深的磨削参数下，其磨削加工性能更加优良。

Abstract: Nano-CMQL was an efficient and environmentally friendly lubrication technology that combined the cryogenic minimum quantity lubrication with lubrication oil containing nanoparticles. The GCr15 hardened bearing steels were machined by using aluminum oxide grinding wheel with 60＃ ceramic bond. The normal grinding force, specific grinding energy，grinding temperature，sub-surface damage and roughness were compared under different grinding parameters under four different grinding conditions which were dry grinding conditions, pour grinding conditions, cryogenic cold air minimum quantity lubrication (CMQL) and Nano-CMQL. The results show that Nano-CMQL, which is prepared by way of adding MoS2 solid particles with particle size 40 nm to the basic grinding fluid, may reduce the normal grinding force and grinding temperature effectively in grinding processes, and has better grinding performances under higher grinding speeds and deeper grinding depths.

Key words: cryogenic nanoparticles minimum quantity lubrication(Nano-CMQL), normal grinding force, specific grinding energy, grinding temperature
