What Is CNC Turning?
Material Rotates
Bar stock or blank is loaded into the lathe chuck and spins at high speed.
Tools Cut
Carbide cutting tools move along the material to remove material and shape your part.
Part Complete
Finished part is inspected on CMM and shipped with full documentation.
Built for Precision Turning
Your turned parts need a shop that treats quality, speed, and material knowledge as seriously as tolerances.
Live Tooling Capability
Our lathes feature live tooling for milling flats, drilling cross-holes, and cutting slots — all in one setup. Fewer operations mean faster delivery and tighter tolerances.
CMM Inspection
Every turned part is CMM inspected before shipping. You get a documented inspection report with every order — no guessing, no shortcuts.
Material Versatility
We turn aluminum, stainless steel, titanium, brass, copper, Delrin, PEEK, nylon, and polycarbonate. Every order ships with material certifications.
Fast Turnaround
Quotes in 24 hours. Prototypes in 3–5 days. Production runs on your timeline. We communicate directly — no layers of sales reps between you and the shop floor.
