Abstract A newly designed and manufactured hybrid MQL system is reported. Vegetable oil and tungsten disulphide suspension are mixed in an additively-manufactured nozzle and delivered through pressurised air as a coolant/lubricant spray. Cooling capability of the system is improved. Lubrication and the impact on machinability is assessed in high speed milling Ti6Al4V. Tool life and cutting forces with the new system are compared to those with air and with flood cooling and with commercial MQL. Over the reported practical range of cutting speeds, tool life is more than 2 times longer than with the commercial system and from 4 to 11 times longer than with air cooling.

一种用于加工难切削材料的新型混合微量润滑系统

摘要 报道了一种新设计和制造的混合 MQL 系统。植物油和二硫化钨悬浮液在增材制造的喷嘴中混合，并通过压缩空气作为冷却剂/润滑剂喷雾输送。提高了系统的冷却能力。在高速铣削 Ti6Al4V 中评估润滑和对机械加工性的影响。将新系统的刀具寿命和切削力与空气冷却、洪水冷却和商业 MQL 的刀具寿命和切削力进行了比较。在报告的实际切削速度范围内，刀具寿命比商用系统长 2 倍以上，比空气冷却长 4 到 11 倍。
