Spinner TC 800

With 900 mm of turning length and a 500 mm maximum turning diameter, the Spinner TC 800 is larger than both the TC400 and the TC600 and is equipped for heavier stock. Bar capacity is 85 - 110 mm, the tool holders are VDI40, VDI50 or BMT65, and the automation Spinner lists for it is the Robobox XL.

The spindle speed row reads 2,600 - 4,000 rpm. That would be slow on a small lathe and is reasonable here, since a 500 mm part or a 110 mm bar reaches its cutting speed at a modest rpm. The table does not pair the speeds with the bar sizes. Expect the 110 mm bore to sit at the lower end and have that confirmed, because a shop that mostly runs 85 mm bar gives up speed for nothing if it orders the big bore.

X travel is 360 mm and Z travel is 900 mm, with one turret carrying up to 16 tool stations. A Y axis of 120 mm is optionally available. On a lathe of this size it serves cross holes, flats and keyways on shafts. No driven-tool speed or power appears in the table, so ask for those when the Y axis is quoted. A tailstock or a sub-spindle is available as well. For shaft work near the full 900 mm the tailstock is the obvious pick, while the sub-spindle suits shorter parts that must be completed on the second side.

The control is Siemens or Fanuc. One size down, the TC600 turns 400 mm by 650 mm, takes 65 - 85 mm bar and reaches between 3,400 and 5,000 rpm.
