Geo Kingsbury introduces UniSpeed 6 for production of large complex parts
1 min read
The UniSpeed 6 machining centre has been developed for the production of large, complex components weighing up to eight tonnes. Geo Kingsbury Machine Tools, sole agent for the German manufacturer SHW, adds that in a mill-turn version, the 3 by 1.6 m table is replaced by a 1.6 m diameter rotary table that allows parts weighing up to three tonnes to be turned in-cycle, with constant surface speed capability, at up to 250 rpm.
The travelling-column SHW UniSpeed 6 has an XYZ working volume of 3,000 by 1,300 by 1,300 mm. Direct drive to the maximum 36 kW/6,000 spindle reduces wear and eliminates the heat generation associated with gears. The 50-taper tools are automatically exchanged from a 48-station magazine. One with up to 120 tool positions is an option. Alternatively, the HSK-A100 taper can be specified.
Despite weighing 45 tonnes, the UniSpeed 6 needs no special foundations, as it has a rigid, composite base to promote surface quality of the machined part, precise manufacturing tolerances and tool life. The Hydropol composite is a special concrete that is described as having around 30 times higher damping capacity than cast iron.
The machining centre has acceleration at 2 m/sec2 up to 30 m/min cutting feed and rapid traverse in all orthogonal axes. CNC control is provided by either a Heidenhain iTNC 530 or Siemens 840D.
