Machining examples using super small precision CNC machine tools ″MTS″

Abstract

Micro Turning System (MTS) series are super small precision CNC (computer numerical control) machine tools for exclusively machining micro–parts. This paper describes achievements of test cutting by the MTS series. Steels, titanium alloy, aluminum alloy, copper alloy, synthetic resins, and bones are chosen as works to machine. The hardness of the hardest work in all the trials was fifty–five in HRC (Rockwell Hardness C Scale) and the MTS could machine it. On the other hand, various machining shapes were tested to process. For example, micro–pins that had steps of order of a few microns, an internal boring indicated to machine by a surface roughness of 0.4 in Ry, and a micro dimple surface with many juts of around 20 microns high, were machined and good performance was confirmed.
