Production Machining in San Jose — Built for Recurring Orders
RivCut isn’t just a prototype shop. We run CNC production machining from 10 to 5,000+ parts for San Jose hardware teams — with consistent quality, dedicated tooling, blanket-order pricing, and predictable lead times month after month. If you’re a San Jose buyer who reorders the same part every quarter, RivCut is built for you.
Blanket POs & Repeat Runs
Blanket orders, locked-in pricing, and dedicated machine time for San Jose customers who reorder month after month. No requoting every cycle.
Build Once, Run Forever
Custom fixtures and locked tool offsets shave minutes off every cycle and lock in repeatability across thousands of parts.
10 to 5,000+ Parts
Bridge runs after prototype validation through low-volume production at 5,000+ parts. Same machinists, same QA, same parts at piece 1 and piece 5,000.
SPC + CMM on Every Lot
SPC monitoring, AS9102 first-article reports, and CMM inspection on every lot. Mill certs (EN 10204 3.1) ship with every shipment.
What Ships With Every San Jose Production Order
Most online CNC platforms are built for prototypes — instant quote, one-off, ship and forget. RivCut runs the other half of the manufacturing cycle: production machining for San Jose OEMs who’ve already validated their design and need a manufacturing partner who will hold tolerances on lot 50 the same way they did on lot 1. We dedicate machine capacity, lock in fixtures, and quote blanket orders so your reorders ship on schedule without re-negotiating every quarter.

RivCut vs CNC Marketplaces vs Local Machine Shops
Why engineers in San Jose pick RivCut over marketplaces and local machine shops. Marketplaces are fast but route your job to the lowest bidder. Local shops are trustworthy but slow on quotes and often won’t take small jobs. RivCut combines instant online quoting with the accountability of a real, in-house USA shop.
| What You Get | RivCut Best | CNC Marketplace | Local Machine Shop |
|---|---|---|---|
| Who cuts the part | Our machinists in Union City, CA | Unknown 3rd party shop | Local machinist, varies by shop |
| Country of origin | 100% USA, never outsourced | Often shipped overseas | USA, local only |
| Instant online quote | Yes — AI-priced in seconds | Yes | No — email or phone quote |
| Talk to the machinist | Yes, direct line | No, support agent only | Yes, in person |
| Free DFM review | Yes, on every order | Sometimes, paid add-on | Sometimes, informal |
| Tightest tolerance | ±0.0002 inches | ±0.005 inches typical | Varies by shop |
| Fastest lead time | 3 business days | 5–10 business days | 2–4 weeks typical |
| Minimum order | None — one part is fine | Often 5+ pieces | Often $500+ minimum |
| CMM inspection | Every order | Paid upgrade | Sometimes, manual only |

What Engineers Say About
Working With RivCut
Real reviews from real engineers. Every project matters — including yours in San Jose.
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.
