SHW UniSpeed 3500

With 3,500 mm (137.8 in) of X travel, the SHW UniSpeed 3500 is the longest of SHW's compact UniSpeed machining centers. Y, the vertical axis, and Z, the horizontal cross axis, are each 1,300 mm (51.2 in). That matches the UniSpeed 2500 with its 2,500 mm (98.4 in) of X, and the rest of the brochure table is shared as well, so the case for this model rests on what the longer bed allows.

Tooling is where SHW's own description of this model gets specific. According to the product page, the ToolRunner tool changer offers space for up to 240 tools. On a machine meant for long parts and mixed one-off work, that capacity lets the tools of several jobs stay loaded, including the long tools a swivelling head tends to need. A tool magazine and a tool loading station are listed under tool handling.

At the cutting end sits SHW's universal milling head in orthogonal design: 180° of standard swivel on A, 360° on C. The drive row reads up to 44/70 kW (59.0/93.9 hp) and up to 8,000/24,000 rpm for main drive/motor spindle, with SK50 BIG-PLUS or HSK 100 A DIN 69893 tool holders. Is 30,000 mm/min quick enough? Over 3,500 mm (137.8 in) of X it keeps repositioning short, and the brochure quotes 2 m/s² of acceleration to go with it.

Versions are milling machine, turn-mill machine and pallet-changing machine; SHW calls the mill-turn configuration optional. Controls are Siemens or Heidenhain. Table size, table load and machine weight are not published for this model, so the floor plan and the heaviest workpiece have to be settled with SHW.
