Precision CNC Machining for Automotive Teams

Automotive companies in Austin need parts that are repeatable, durable, and cost-effective. A drivetrain housing that's off by 0.003 inches affects assembly fit and seal performance. We machine aluminum, steel, and stainless to tolerances as tight as ±0.0005 inches with full documentation.

Automotive Manufacturing in Austin

Austin is at the center of Texas's automotive revolution. Tesla's Gigafactory Texas in southeast Travis County is one of the largest automotive manufacturing facilities in the world. The factory produces Model Y, Cybertruck, and eventually the next-generation Tesla platform. Tesla's presence has attracted a cluster of EV suppliers, charging infrastructure companies, and automotive technology startups to the Austin area. Rivian, TuSimple (autonomous trucking), and dozens of smaller mobility startups have Austin operations. We machine motor brackets, battery enclosure hardware, sensor housings, and structural components for Austin automotive teams. Aluminum, steel, and copper. Instant pricing. No minimums.

Yes. RivCut holds AS9100 and ISO 9001 certifications. Many Austin-area automotive buyers, including Tier 2 suppliers near the Tesla Gigafactory in southeast Austin, require these. Our certifications show we follow strict quality systems. You can request our current certificates before placing any order. We keep them up to date every year.
We machine aluminum, steel, stainless steel, and titanium. Austin automotive projects often call for 6061 aluminum and 4140 steel. We also work with plastics like Delrin for prototype parts. If you supply to the Tesla Gigafactory or local racing teams on Circuit of the Americas, we can match your material spec exactly.
RivCut holds tolerances as tight as plus or minus 0.0005 inches. Most automotive parts you need fall between plus or minus 0.001 and 0.005 inches. We use CMM inspection to verify every critical dimension. Tell us your GD&T callouts up front. We review your print before cutting so there are no surprises.
Standard lead time is 10 to 15 business days. Rush orders can ship in 3 to 5 business days for an added fee. We are located in the Riverside Industrial area, so we can deliver locally in Austin same day if needed. Suppliers racing to meet Tesla build schedules often use our rush service.
Every order ships with a certificate of conformance and a full inspection report. We also provide material certifications from our metal suppliers. If your Austin facility runs PPAP or APQP processes, we can prepare those documents too. Just tell us what your quality team needs before we start your job.
Yes. We buy stock from metal service centers in the Austin and San Antonio corridor, including suppliers along Highway 183 South. Local sourcing cuts your lead time and lowers freight cost. It also helps Austin automotive buyers who need to track domestic material origin for supply chain compliance or customer reporting requirements.
