Abstract
In manufacturing technology, it is a dominant tendency in recent years that machine tools for turning, milling and so on, employ electric operated actuators such as a servo-motor equipped with a ball screw. The problems with these electric driving machine tools are, they are excessively large-sized with complex machinery and they are expensive, as seen in their application to, for example, NC-machine. In order to solve these problems, we developed a precision driving system actuated by a hydraulic cylinder in the previous report of this study. This present report deals with the ability test of turning, drilling and milling by applying the previously developed driving system to a micro-machine-tool. The cutting results were compared with the ones obtained by conventional NC-machines. It was confirmed that the developed machine has superior ability over the conventional ones.
