Micro Line high speed spindles for Swiss turning are described as compact and powerful. In addition to the 25-mm-diameter model, 20- and 22-mm versions have been added to the line. For example, the model HT 25S 60, which is 63.3-mm long, is suitable for space-constrained tool zones in Swiss-type machines. Right-hand spindles are available. The spindles use synchronous, DC motors and operate at speeds as fast as 120,000 rpm. They are designed for machining applications involving micro-milling and drilling tools, as well as engraving and fine milling. They feature high rigidity and precision (less than 2 microns runout) to increase surface quality and machining accuracy, the company says.
