CNC turning for parts that spin, slide, and seal

Shafts, pins, bushings, and fittings — round parts where concentricity, thread quality, and surface finish do the real work. Turned to your print, checked before packing.

Typical work

What we turn

Shafts & pins

Stepped shafts, dowels, and locating pins with ground-fit diameters, keyways, flats, and cross-holes added in secondary operations where the design calls for them.

Bushings & spacers

Bearing seats, wear bushings, and precision spacers — bores and outside diameters cut in the same clamping so they stay concentric where it counts.

Fittings & adapters

Threaded fittings, nozzles, unions, and custom adapters. Internal and external threads, sealing faces, and hex or knurled grips as drawn.

Turn-mill parts

Round parts with milled features — flats, slots, bolt circles — planned as one job so the milled geometry references the turned datums.

Craft, stated plainly

What we watch on turned work

Concentricity & runout

Features that must run true get machined in one clamping wherever the geometry allows. Where it doesn't, we plan the re-chucking rather than hope it averages out.

Threads & fits

Threads are gauged, not eyeballed. Sliding and press fits are machined to the class on your drawing — if the callout is missing, we ask instead of guessing.

Surface finish

Sealing surfaces, bearing journals, and cosmetic faces each want a different finish strategy. Mark the Ra where it matters and it gets treated as a dimension.

Batch consistency

Repeat orders run from the saved setup and program, with in-process checks against the same print. The tenth batch should measure like the first.

Materials

Frequently turned

Free-machining steels and brass are natural turning stock, but stainless, aluminum, and plastics are just as common. Full guide on the materials page.
