Most deviations caused by thermal influence are covered by the symmetrical structure of these vertical machining centres. In addition to the high mechanical accuracy, a precisely counterbalanced mechanical geared working spindle serves to guarantee optimum machining results. SB models can be equipped with interchangeable milling heads. The machine height can be reduced by using the control panel attached to the side of the machine. Spindle speed is up to 6,000 min-1.
