3, 4, & 5-axis CNC milling — for parts that can't be wrong.
From prototype singletons to 50,000-piece production runs. ±.0002" repeatable across 200+ stocked material grades. AS9100D + ITAR. Engineer review on every quote, AI-assisted scheduling, real-time job costing while the chips are still flying.
From single-feature prototypes to multi-setup production parts.
We choose 3-, 4-, or 5-axis based on geometry and economics — not what's free on the floor. A simple 2-op aluminum bracket runs on a 3-axis VMC. A turbine housing with compound 5-sided geometry runs on a 5-axis trunnion. The platform's AI estimator routes each part to the right machine class automatically, then a real engineer signs off.
3-axis milling
Vertical machining centers up to 50" x 26" x 25" envelope. The bulk of K+G's daily volume — brackets, plates, housings, manifolds. Fixturing is the lever here; tight repeat-fixturing on production parts means we hold features to ±.0005" pass after pass.
4-axis milling
Trunnion or rotary-table 4th-axis on selected VMCs. Cuts setups in half for parts that need access on 3–4 sides. Common workhorse for shaft features, indexed hole patterns, and family-of-parts production where the part rotates between ops.
5-axis milling
Simultaneous 5-axis on aerospace work — turbine housings, structural brackets with compound mounting features, medical instrument geometry. Done in one setup. No multi-fixture stack-up error. AS9100D-controlled.
If it's machinable, we run it.
Material selection drives feeds, speeds, tooling, and fixturing. Pick the page that matches your part — each links back to milling so the request lands routed.
