다국어 초록 (Multilingual Abstract)

This paper has studied thermal characteristics of machine tool to develope high speed spindle and optimum design condidering the thermal deformation.
Comparing the test data of temperature measurement and structural analysis data using FEM, we verifiedthe test validity and predicted thermal deformation, influence of spindle generation of heat, and established cooling system to prevent the thermal deformation.
1) The temperature rise of spindle system depends on increasing number of rotation and shows sudden doubling increment of number of rotation over 7,000rpm.
2) Oil jacket cooling can be effective cooling method below 8,000rpm but, over 8,000rpm, it shows the decrement of cooling effect.
3) Comparing FEM analysis results and revolution test results, we can confirmn approximate temperature change consequently, it is possible to simulate temperature rise and thermal distribution on the inside of spindle system.
4) We can confirm that simulated approach by FEM analysis can be effective method in thermal-appropriate design..
