Last update September 2009. ·Higher rigidity and larger grinding quill holder 1.2 Output S6-60% [kW] This was realized particularly by the following features of the UHS spindles: Output diagram The SD inverter matched optimally to the operation of the UHS spindle and the appropriate lubricator PRELUB PP can be obtained from us. The connection cables and lubricant pipes required for this belong to the standard scope of delivery. crad When designing this spindle type, the demand to offer a product with which our customers can achieve maximum quality and optimum productivity was taken as the basis.
