Vibration reduction effect of counter balance feed mechanism by right and left ball screw drive and guidelines for the design method of this mechanism

Abstract

Recentry, due to the lighter, thinner, shorter and more multifunctional electronic equipment, high precision through hole processing is required on the printed circuit board. Therefore, in this study, vibration reduction at the column of machine tool is realized by mounting counter balance feed mechanism by right and left ball screw drive on machine tool. It can be confirmed that it is important to determine the weight and center of gravity position of the spindle and counter while maintaining the driven at center of gravity (DCG), and also proposed guidelines for the design method of this vibration reduction mechanism.
