Assessment of High Speed Spindle Accuracies

open access: yesJOURNAL OF ADVANCES IN CHEMISTRY, 2017
The spindle error contributes to 25 percent of the error sources of the work piece in- accuracies. The 70 percent of the spindle errors are due to thermal errors that occurs in the spindle. The heat generation in high-speed built-in motorized spindle is of important concern in high speed machining.
