What Are CNC Production Runs?
CNC production runs make the same part over and over with perfect consistency. We set up dedicated fixtures and tooling to machine hundreds or thousands of identical parts. Every piece matches the first one. Volume pricing brings your cost per part way down. Durham teams use our production runs for consistent, repeatable CNC parts at volume pricing.
Fixture Design & Lock-In
We build custom fixtures for your part. This keeps every piece identical across the full run.
Process Locked & Verified
Toolpaths, feeds, and speeds are dialed in. The first article proves the setup works.
Batch Monitoring & QC
SPC tracks every critical dimension during the run. Final CMM reports ship with your parts.
Built for Production Teams
Your production run needs a machining partner who delivers consistent parts, on time, with full documentation.
Scalable Capacity
From 1 part to 5,000+. We scale to your quantity without sacrificing precision. Dedicated fixtures and optimized toolpaths keep every part identical.
CMM Inspection
Every critical dimension is verified before shipping. Your receiving team gets a documented inspection report — no guessing, no shortcuts.
Process Repeatability
Same material lot, same tooling, same setup. SPC monitoring tracks every critical dimension so part #5,000 is identical to part #1.
Fast Response
Upload your file and get a response fast. Production runs in 2–4 weeks. We communicate directly — no layers of sales reps between you and the shop floor.
Built for Volume. Built for Quality.
Everything you need for reliable production machining.

1 to 5,000+ Parts
We handle runs of any size. Whether you need 10 brackets or 5,000 pins, every part gets the same precision and attention.
Any quantityDedicated Fixturing
Custom fixtures hold your parts exactly the same way every time. This keeps tolerances tight and quality consistent across the entire run.
Repeatable setupSPC Monitoring
Statistical process control tracks dimensions throughout the run. We catch drift before it becomes a problem. Your parts stay in spec from first to last.
Real-time trackingBatch Consistency
Same material lot, same tooling, same setup. We control every variable so part #5,000 is identical to part #1.

What Engineers Say About
Working With RivCut
Real reviews from real engineers. Every project matters — including yours in Durham.
We went through two shops before finding RivCut. Night and day difference. Parts come in right. Communication is clear. They held ±0.002" on a titanium bracket that two other shops couldn’t get right.
Aerospace PartsThey caught a tolerance issue in our drawing before production started. That saved us a full revision cycle and three weeks of delays. You don’t find that kind of attention to detail at most shops.
Medical DeviceWe needed fast turnaround on 5-axis parts for a new enclosure. RivCut delivered in 6 days. Quality was excellent. These guys move fast without cutting corners.
