Thermal Characteristics of a Vertical Guideway System including Hydrostatic Bearings and Ballscrew Drive of Precision Milling Machines

EasyChair Preprint 404

Abstract

This paper simulates the thermal characteristics of a vertical hydrostatic guideway using ANSYS/Fluent in precision milling machine applications by considering the oil film friction of hydrostatic bearings in operational feed speed and heat generation in ballscrew nut .  Temperature rise in individual hydrostatic bearing due to different supply pressure, feed speed, and oil viscosity will be analyzed, and the thermal displacement of the center point of worktable can be predicted in case of thermal deformation.

Keyphrases: Thermal deformation, finite element analysis, vertical hydrostatic guideway
