Precise temperature control in high-speed metal cutting machines is vital to reduce friction-induced heat, requiring specialized lubrication and cooling systems like the oil-air system. Over 60 years, models using the Finite Element Method (FEM) and numerical techniques have been developed to study spindle and bearing thermal behavior. This paper introduces an integrated spindle model based on the Takisawa MAC-V0, addressing time efficiency and lubrication assessment limitations in previous models. Built in Open Modelica, it enables rapid thermal analysis and lubrication validation. The model, validated with the MAC-V0 spindle, achieves accuracy within 1–2 degrees at spindle speeds of 6600–8400 rpm.

摘要

Precise temperature control in high-speed metal cutting machines is vital to reduce friction-induced heat, requiring specialized lubrication and cooling systems like the oil-air system. Over 60 years, models using the Finite Element Method (FEM) and numerical techniques have been developed to study spindle and bearing thermal behavior. This paper introduces an integrated spindle model based on the Takisawa MAC-V0, addressing time efficiency and lubrication assessment limitations in previous models. Built in Open Modelica, it enables rapid thermal analysis and lubrication validation. The model, validated with the MAC-V0 spindle, achieves accuracy within 1–2 degrees at spindle speeds of 6600–8400 rpm.
