The demand for compact products has raised the need for high-speed machining. In this study, we have designed and produced a desktop machine tool and investigated its high-speed machining performance using a small end mill. The size of the developed machine tool is 300×400×340mm, and the weight is 50 kg. This machine could reach a cutting speed of 25.0 m/s using a 1.7 mm diameter tool. High-speed milling with this machine produced a surface roughness of 0.6 µmRz without tearing. In addition, deformed layers produced at cutting speed of 25.0 m/s was thinner than that at cutting speed of 2.5 m/s. It was confirmed that the thickness of deformed layers at 25.0 m/s was 0.6 µm.
