Recently, a demand of small parts increases with the popularization of the portable type product. Therefore, the small diameter tool is used in the processing of small parts. However, it is difficult that high speed machining is realized in the, existing machine tool using the small diameter tool. Because the spindle rotational frequency of existing machine tool is due to be low. In addition, it is inferior to the energy efficiency, since using machine tool is very big for the small workpiece. Therefore, it is necessary to develop the small machine tool in which high speed machining is possible. And the high-efficient processing using high-speed machining seems to be the usefulness in order to milling the small parts with the small diameter tool.In this study, design and production of desk-top type small machine tool were carried out. And cutting performance of small end mill tool at high-speed condition is investigated. The size of developed machine tool is 300×400×340mm, and the weight is 50kg. This machine enabled under 25.0m/s condition using the small diameter tool of 1.7mm. As a result of high-speed milling with this machine, it was clarified that the surface roughness of 1.6μmRz without tear parts was obtained in the cutting speed condition of the 25.0m/s. In addition, the thickness of deformed layer after cutting under 25.0m/s condition decrease in comparison with 2.5m/s. It was confirmed that the value became 0.6μm.

近来，随着便携式产品的普及，对小部件的需求增加。因此，小直径刀具用于小零件的加工。然而，在使用小直径刀具的现有机床中难以实现高速加工。由于现有机床的主轴转速较低，此外，它的能源效率较差，因为使用机床是非常大的小工件。因此，有必要开发小型机床，在高速加工是可能的。为了用小直径刀具铣削小零件，高速切削的高效加工似乎是有用的。本研究进行了台式小型机床的设计和生产。研究了高速条件下小口径立铣刀的切削性能。研制的机床尺寸为300×400× 340 mm，重量为50 kg。该机床可在25.0m/s的条件下使用1.7mm的小直径刀具。在25.0m/s的切削速度条件下进行高速铣削加工，可获得1.6μmRz的表面粗糙度，无撕裂。另外，25.0m/s条件下切削后的变形层厚度比2.5m/s条件下切削后的变形层厚度减小。确认该值变为0.6μm。
