Zusammenfassung:While many components used in automobiles, household electric appliances, etc., are becoming more compact, the size of most machine tools used for machining such components remains unchanged. Therefore, to improve the efficient use of factory space and economical use of energy, machine tools are required to be compact adopting to the size of workpieces. Therefore, in spite of the many requirements of the market related to the miniaturization of machine tools, a miniaturized NC machine tool has not been widely regarded. The conventional structure of machine tools such as a cast body or welded steel plate body is recognized as being the best. This preconception is one of the obstacles to solving this problem. We have developed a new CNC lathe with a pipe frame structure. This structure is expected to enable the miniaturization of machine tools while ensuring sufficient space for the discharge of cutting chips. In this structure, the heat transfer between the pipe elements and connecting blocks strongly affects the axial displacement of the pipes. In this paper, we investigated fundamental performance of the developed lathe, and machined workpieces precision by comparing those of conventional lathes.
