Low-volume CNC parts, machined and finished.

Representative parts off our floor. Client drawings stay confidential — every photo here is shared without client marks, and new case studies are added as shipments clear.

Aluminum plate with four machined mold cavities

Multi-cavity mold plate

AL 6061 · 3-axis mill · 4-up cavities · ±0.02 mm

Four matched cavities in one setup — alignment between cavities held without re-fixture.

Tray of mirror-finish precision shafts

Mirror-finish precision shafts

Steel · Swiss-type turning · batch · Ra-mirror shoulders

Stepped shafts run bar-feed in one pass; shoulders finished to a mirror for a sealing application.

Four black anodized aluminum sensor housings in a tray

Black-anodized sensor housings

AL 6061 · mill + Type II black anodize · repeat order

Milled, anodized and laser-marked under one roof — repeat batches ship on a fixed lead time.

Batch of slender black-oxide threaded shafts

Slender threaded shafts, black oxide

Steel · Swiss-type + thread milling · black oxide

Long, thin, threaded — the geometry that general lathes re-chuck twice and Swiss lathes don't.

Large aluminum block with dual radius pockets

Large block, dual-radius pockets

AL 6082 · 3-axis mill · large envelope · ±0.05 mm

Big-envelope milling with matching radii — roughing and finishing strategies tuned to hold flatness.

Four polished stainless steel torpedo-shaped parts

Polished stainless assemblies

Stainless · turn + mill + polish · cosmetic grade

Turned bodies with milled flats, polished to a cosmetic finish for a visible assembly.

Stainless steel threaded fittings, one held in hand

Stainless threaded fittings

Stainless · turning + thread rolling · batch

Tapered thread bodies with batch-consistent gauge fit; threads rolled for strength where specified.

Curved aluminum parts with multiple machined features

Curved multi-feature brackets

AL 6061 · 3+4-axis mill · prototype to repeat batch

Compound-angle geometry that started as a 5-piece prototype — same fixtures now run the repeat orders.
