Billet aluminum part machined for San Jose engineering and hardware companies

CNC Machining for San Jose & Silicon Valley — Affordable, Fast, American-Made

San Jose and Silicon Valley companies rely on precision machining every day — from robotics startups and hardware engineers to medical device manufacturers and semiconductor suppliers. But machining in the Bay Area is expensive, overbooked, and often locked behind long lead times.

McCarty Fabrication provides a better option.

Located in rural Kentucky with lower overhead, fast turnaround, and all work done in-house, we offer Silicon Valley engineers the precision and reliability they need — at pricing that outperforms local machine shops.

We ship CNC-machined parts nationwide and regularly support customers in:

  • San Jose

  • Palo Alto

  • Santa Clara

  • Fremont

  • Sunnyvale

  • Mountain View

  • Milpitas

  • Cupertino

  • Silicon Valley manufacturing hubs

If you need reliable machining for prototypes, production runs, or highly-accurate components, we can help.

Why San Jose Companies Work With Us

Lower Cost Than Bay Area Shops

San Jose and Silicon Valley machining rates are some of the highest in the country.
Our rural Kentucky location gives us significantly lower overhead — and our customers benefit directly from it.

Fast Turnaround for Product Teams

Instead of multi-week lead times, most of our jobs ship within days.
We specialize in quick prototypes and small production batches that keep engineering schedules moving.

American-Made, Owner-Operated

You work directly with the machinist — no account managers, no middlemen, no automated quoting system that doesn’t understand your design intent.

Nationwide Shipping

We ship insured and tracked to San Jose and all surrounding areas using UPS, USPS, or FedEx.

Industries We Serve in San Jose / Silicon Valley

Medical Device Manufacturing

San Jose is a major medical innovation hub.
We machine components such as:

  • surgical hardware

  • prototype medical housings

  • brackets, plates, and assemblies

  • 6061 and 7075 test components

  • stainless steel 304 / 316 parts

  • hardware for medical tools and fixtures

We understand precision requirements, surface finish expectations, and repeatability standards required for medical engineering teams.

Product Designers & Hardware Startups

We support early-stage and established engineering teams with:

  • prototypes

  • tolerance testing

  • fixture development

  • bracket and plate machining

  • small-batch pre-production runs

If you’re moving from CAD to physical parts, we can help.

We support a wide range of high-tech manufacturing sectors, including:

Semiconductor Manufacturing & Equipment

The semiconductor industry demands ultra-clean, accurate, and reliable components.

We supply machined parts for:

  • wafer-handling hardware

  • alignment fixtures

  • automation components

  • prototype housings

  • aluminum brackets and plates

  • test and validation equipment

San Jose companies often struggle with long semiconductor supply chains — our shop provides fast turnaround to support development timelines.

Automotive, EV, and Mobility Industries

San Jose’s transportation and EV ecosystem continues to expand.
We machine:

  • custom housings

  • drivetrain brackets

  • sensor mounts

  • aluminum components

  • 7075 performance hardware

Robotics & Automation

Silicon Valley robotics companies rely heavily on:

  • precision aluminum frames

  • actuator mounts

  • custom brackets

  • sensor housings

  • test equipment

  • prototype mechanisms

We machine both one-off prototypes and repeat batches for robotics teams.

Prototype to Production — Built for Engineering Teams

San Jose companies rely on us because we specialize in exactly what Bay Area teams need:

✔ Fast prototype machining

✔ Repeatable small-batch production (10–50 pcs)

✔ Affordable pricing

✔ Tight tolerances

✔ Responsive communication

✔ Nationwide shipping

✔ American-made manufacturing

We understand engineering workflows — STEP files, revisions, testing cycles, prototype batches, tolerance verification — and we communicate directly during every stage of the project.

Why Our CNC Shop Beats Big Online Platforms

Online machining platforms like Xometry, Fictiv, and SendCutSend offer convenience — but with big limitations:

1. Higher pricing due to middlemen

Platforms mark up your parts 15–40% before sending them to a shop like ours anyway.

2. No direct contact with the machinist

If something needs clarification, you’re stuck waiting for a support rep instead of speaking with the person making your part.

3. Lead times are longer

Platforms batch jobs to maximize their profits.
We machine your parts immediately.

4. No flexibility

Need a small tweak?
Need help optimizing the design?
Need a fast prototype?
Platforms can’t accommodate — we can.

For San Jose companies, partnering directly with a rural American shop is the most cost-effective, consistent, and transparent solution.

Rural Shop Advantage — Better Pricing for San Jose Engineering Teams

Operating in Kentucky gives us major advantages over Bay Area machine shops:

  • lower labor cost

  • lower facility overhead

  • lower insurance

  • lower operational expenses

You get San Jose-level precision without paying Silicon Valley prices.

This pricing advantage is why many California startups and engineering teams now work directly with smaller rural CNC shops like ours.
