Up to now balancing of main spindles for diamond machining has been done in one plane only. This principle works fine, as long as the balancing mass is in the same plane as the center of gravity of the workpiece or tool respectively. Whenever this condition is not given a residual momentum will be induced by the unbalance, leading to vibrations. This effect is amplified for excentric workpiece mounting or if workpieces with large spatial masses are machined. The vibrations will lead to an increased surface roughness and a decrease in form accuracy as well. Therefore, the balancing quality is a crucial factor, especially in ultraprecision diamond machining where more often the mounting situation is exceptional, e.g. for large optical parts. In contrast to conventional machining significant higher balancing quality is required. So far machine tools for ultraprecision machining have not been designed for two plane balancing, hence the balancing quality is limited by the stiffness of the main spindle and the dimensions of the workpiece. To overcome these limitations and to get a better understanding of the workpiece quality as an interaction between balancing situation and machine tool in diamond machining a concept for a machine tool has been developed, that includes two relocatable balancing planes and allows to adjust stiffness and damping. The setup is under construction and will be used to vary machine tool configurations including stiffness and damping properties.
