Capability — CNC Turning

Turning with the milling built in.

Eight turning centers, several with Y-axis and sub-spindle, so a chucked part is turned, milled, drilled and finished on the back side without leaving the machine.

Chucked work larger than bar capacity runs here: flanges, hubs, adapters, rings, spindles and housings. The Okuma Genos L400II-E handles the heavier envelopes; the DMG MORI NLX 2500SY/700 and NL1500SY/500 bring Y-axis and sub-spindle for done-in-one parts; the Takisawa TCC series and Haas ST-10 and SL-10 cover the middle of the range.

Contour, form, taper and straight turning, single-point threading, grooving, boring and off-center milled features. Because the second operation happens on the sub-spindle, the front-to-back relationship is held by the machine rather than by a re-chuck.

Turned diameters are held to a standard ±.0005 in, with critical features to ±.0001 in when the print calls for it — verified against print datums on the CMM before shipment.

How the work runs
  1. 01

    Workholding review

    Chuck, collet or soft jaws selected so clamping does not distort a thin-walled part.

  2. 02

    Done-in-one programming

    Front and back operations combined on the sub-spindle where the geometry allows.

  3. 03

    First article

    Dimensional report against print datums before the balance runs.

  4. 04

    Final inspection

    Critical diameters and geometric callouts verified on the CMM.

Common questions

CNC Turning, answered plainly.

What is your maximum turning diameter?

Up to roughly 12 in in diameter and 28 in in length depending on the machine and workholding.

Can you do turning with milled features?

Yes — Y-axis and sub-spindle machines cut flats, slots, keyways and off-center holes without a second setup.

Do you offer outside processing?

Yes. Anodize, passivation, plating, heat treat and NDT are coordinated through approved sources and documented on the shipment.
