Precision grinding and micromachining both impose high demands on the machine behavior, since the achievable workpiece accuracy is determined not only by the technological parameters but also by the characteristics of the applicated machine components. Ultraprecision surface quality and the mechanical fabrication of structures in the micron range can only be achieved by using machine tools which have appropriate spindles. Structures cannot be manufactured using spindle types of which the radial error motion is greater than the level of contour accuracy or surface roughness required. In addition, the spindle speed is an important value. Not only a certain cutting speed is needed from the technological point of view, but also the machining time required for microstructuring surfaces is reduced by deploying a high frequency spindle, thereby increasing the economic efficiency of the technique. Hence, the main purpose of the project was to develop a high speed spindle with properties concerning accuracy, speed and stiffness beyond commercially available ones.
