Suhner presents an innovative grinding, milling, and polishing system under the name SUNmic 60, a micro motor system. The central element is an intelligent control unit with touch panel that can take a range of micro motors and tool hand pieces depending on the application. The control part has modern features, such as touch screen operation on a glass display, the option to save settings, and a rotation speed regulator with tangible resistance. Key settings are easily legible on a large digital display. The actual tools are driven by powerful micro motors whose 280 W places a lot of power in the user’s hand. The compact, brushless BL/DC motors provide an extraordinarily wide speed range of 1000–60,000 rpm and deliver a high torque. In practice, they can be compared with pneumatic technologies, but do not need a compressed air supply, operate at lower energy levels, and emit virtually zero noise, and that without exhaust air and without oil mist. One further benefit is that they run virtually free of vibrations.
