CNC Milling
3-, 4-, and 5-axis CNC milling for complex geometries and tight tolerances. Aluminum, steel, titanium, and engineering plastics — we machine what your design requires.
Waterbury, Connecticut
CNC milling, turning, and custom fabrication — from single prototypes to full production runs. Built on decades of hands-on expertise, delivered with the attention your parts demand.
What We Do
From blueprints to finished parts, we handle the full machining process — no shortcuts, no compromises on quality.
3-, 4-, and 5-axis CNC milling for complex geometries and tight tolerances. Aluminum, steel, titanium, and engineering plastics — we machine what your design requires.
Precision turning for shafts, bushings, sleeves, and cylindrical components. Consistent surface finishes and repeatable accuracy across every batch.
Bespoke parts and assemblies that don't come off a shelf. We work from your drawings, samples, or ideas — and help refine the design for manufacturability.
Rapid prototyping that moves from concept to physical part fast. Validate fit, form, and function before committing to production tooling.
Low to medium-volume production with consistent quality from first part to last. We scale efficiently without sacrificing dimensional integrity.
Every part is inspected against your specifications. Dimensional reports, material certifications, and traceability — documented and ready.
