Precision CNC contract machining
Every part carries its own route. We do not skip a step to hit a date.
Milling, turning, grinding and thread work for aerospace, medical and defense primes — quoted from your drawing, run with a real process route, and shipped with a first-article inspection report.

The route sheet
Every part travels a route. We publish it.
A route sheet is the shop's own record of how a part actually got made — which machine, which tool, in what order. We hand you that record with the part, not a summary of it.

A single-point insert with a 0.4mm nose radius, run at a real chip load, holds a theoretical Ra well under a micron before anything is ground.

Ra ≈ f² / 32r — the same formula on every lathe operator's speeds-and-feeds chart.
