CNC Turning Explained

What Is CNC Turning?

CNC turning is a machining process where a lathe spins your raw material while precision cutting tools shape it into round parts. It produces shafts, pins, bushings, fittings, and other cylindrical components with smooth surfaces and tight tolerances — fast, repeatable, and accurate.
1

Material Rotates

Bar stock or blank is loaded into the lathe chuck and spins at high speed.

2

Tools Cut

Carbide cutting tools move along the material to remove material and shape your part.

3

Part Complete

Finished part is inspected on CMM and shipped with full documentation.

Why RivCut

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.

Medical Device Manufacturing

Minneapolis medical OEMs turn millions of bone screws, spinal rod connectors, and catheter tip housings every year. Medtronic, Abbott's cardiac rhythm division, and Smiths Medical all have facilities in the Twin Cities.

Industrial & Energy Equipment

Agricultural equipment manufacturers like AGCO, Toro, and CNH Industrial need turned hydraulic fittings, PTO shafts, and pump components. These parts see heavy use in harsh field conditions.

Minneapolis precision optics and sensor...

Minneapolis precision optics and sensor companies need turned lens housings, collimator barrels, and mirror mounts with ultra-tight bore concentricity. These components position optical elements to within microns.

Semiconductor Equipment

Medical Alley Association companies — including Medtronic, Abbott, and dozens of startups — rely on precision-turned implant shafts and instrument components. Enterprise Minnesota's supplier network connects medical OEMs with Swiss-turning shops that hold the tolerances biocompatible materials demand.

FAQ

CNC Turning Questions

CNC turning is a way to make round parts from metal or plastic. A lathe spins your material while cutting tools shape it. This makes shafts, pins, bushings, and fittings with smooth surfaces and tight tolerances.
Most metals and plastics can be CNC turned. We work with aluminum, stainless steel, titanium, brass, copper, Delrin, PEEK, nylon, and polycarbonate.
Pricing depends on material, complexity, and quantity. Simple turned parts start around $30–$120 each. Upload your file for an exact quote in 24 hours.
Live tooling adds rotating tools to a CNC lathe. This lets us mill flats, drill cross-holes, and cut slots without removing the part. It combines turning and milling in one setup for faster delivery.
Our standard turning tolerance is ±0.001". We can hold ±0.0005" on critical dimensions like bearing journals and mating surfaces. Swiss turning can achieve even tighter tolerances on small parts.
CNC turning spins the material on a lathe to make round parts like shafts and bushings. CNC milling holds the material still and uses a spinning cutter to make flat and 3D shapes. With live tooling, we can do both in one setup.
Yes. Our Swiss-type lathes make small, precise parts under 1 inch in diameter. They hold tight tolerances on tiny components like medical pins, electronic contacts, and miniature shafts.
We accept STEP, IGES, DXF, PDF, SolidWorks (.sldprt), and STL files. STEP files work best because they keep all the design details.
We have no minimum. You can order just one part. We make everything from single prototypes to production runs of 5,000+ pieces. Every order gets the same care and precision.
Upload your CAD file on our instant quote page. You'll get a price within 24 hours. No phone calls needed. No pressure.
Yes. We work with Minneapolis teams across medical device, agriculture, and industrial equipment and more. Most orders reach the Twin Cities area in 2–4 business days via ground shipping. We also serve teams in St. Paul, Bloomington, Eden Prairie, and across Minnesota.
Most orders ship in 5 to 10 business days. Rush orders ship in as few as 3 days. Most orders reach the Twin Cities area in 2–4 business days via ground shipping.
Minneapolis medical OEMs need precision-turned implant components and instrument shafts. We turn parts in titanium, stainless, and PEEK. We offer fast quotes, no minimums, and CMM inspection on every order.
Bone screws, spinal rod connectors, catheter tip housings, and pacemaker lead pins are common. We turn these from titanium, cobalt chrome, and PEEK on Swiss machines for single-setup accuracy.
Yes. Hydraulic fittings, PTO shaft adapters, and pump shafts are regular orders. We turn these from hardened steel and stainless with surface finishes that resist wear in harsh field conditions.
Yes. PEEK is a common turning material for medical devices because it is biocompatible, radiolucent, and sterilizable. We turn PEEK components with the tight tolerances and smooth finishes implantable applications require.
Optical housing bores typically need TIR under 0.001 inches, with some applications requiring 0.0005 inches. We turn these on Swiss machines with boring bars optimized for roundness and surface finish.
Enterprise Minnesota helps manufacturers improve operations and connect with suppliers. The Minneapolis Regional Chamber supports businesses across the Twin Cities. Minnesota Manufacturers' Center provides training and certification programs for manufacturing companies statewide.
Yes. Medical Alley Association represents over 800 health innovation companies across the Twin Cities. It is one of the largest medical device clusters in the world. Members include Medtronic, Abbott, and dozens of startups that need local CNC machining partners for prototyping and production.
