Abstract

There are several problems associated with the milling process using end mills with an ultra-small diameter, such as low cutting accuracy, short tool life, and tool breakage. In this study, the relationships between these problems and imbalance of the machine tool main spindle were investigated. The results of this study indicated that machine tool main spindle imbalance caused expansion of the width of the cut groove and increased burr formation. In conclusion, it was suggested that a precision groove corresponding to the diameter of the end mill could be obtained by reducing the rotational imbalance to less than 2 nm.
