2018 Doosan Puma 5100LC CNC Lathe

The 2018 Doosan Puma 5100LC is a heavy-duty, long-bed turning center built specifically for the class of work that most lathes can't touch. The 10.75" through-bore is the headline spec — it opens the machine to large-diameter bar stock, structural pipe, and tubing that would require secondary operations or a completely different machine on anything with a smaller bore. At 25" maximum turning diameter and 82" maximum turning length with 84" between centers, this machine handles shafts, rolls, large cylinders, and heavy-industry components that define high-value, hard-to-source capacity on the open market. The 25" 3-jaw manual chuck, rear chuck prep for extended or pass-through setups, tailstock, chip conveyor, and Fanuc control make this a fully equipped production machine that an operator can step up to on day one without a learning curve.

Where the standard Doosan Puma 5100 (non-LC) configuration handles large-diameter work on shorter components with approximately 51" of turning length, the 5100LC's long-bed designation extends that to 82" — a 60% increase in turning length that fundamentally changes the jobs this machine can bid on. That gap is even more pronounced against the Puma 4100, which carries a roughly 6.7" bore capacity and a comparably shorter bed; the 5100LC's 10.75" bore and extended center distance puts an entirely different tier of raw material and finished component within reach. For shops working offshore, power generation, heavy equipment, or large structural fabrication, the 5100LC isn't an upgrade to an existing lathe — it's access to a category of work the previous machine simply couldn't quote.
