STATIC AND MODAL ANALYSIS OF HIGH-SPEED CNC MILLING SPINDLE

Claudiu-Ioan RUSAN, Cornel CIUPAN

Abstract


The current paper analysis minimum static deflection of high-speed milling spindle at different span length bearing. The spindle design running at 12000 rpm with power rating of 25 Kw and the bearing angular contact value are 15⁰, the main spindle shaft is design for tool holders HSK-A 63. Static and dynamic analysis have an important role in estimating stresses, strains and displacements of the high speed milling spindle, where the static analysis can determinate the system rigidity and dynamic analysis show the natural frequencies and different mode of shape at different of speed of the milling spindle and obtain frequency response function. Further we evaluate the deflection nose, static and modal analysis by theoretical calculations and comparison with SolidWorks Simulation results.
