Precision CNC Machining in

San Diego

Precision Manufacturing, Engineered from the Start.

Engineering-led CNC machining, prototyping, and manufacturing solutions for high-precision parts requiring tight tolerances and reliable turnaround.

Precision Engineered Solutions

12th Dimension Industries is a precision machine shop that specializes in engineered CNC manufacturing solutions, small batch prototyping, and full scale production of machined components. We work directly with engineers, designers, and manufacturers who need parts made right — with attention to detail, clear communication, and accountability.

We operate as an engineering-led, hands-on manufacturing shop, which allows us to stay closely involved in every project, remain flexible where it matters, and maintain consistent precision across all work we take on.

Why 12th Dimension

Where Engineering Leads Manufacturing.

12th Dimension Industries is engineer-owned and operated. That means every project is approached with an understanding of design intent, tolerances, and real-world manufacturing constraints — not just a set of dimensions on a print.

We don’t just cut parts. We think through them.

Clear Communication, Start to Finish

You work directly with the people making your parts. No account managers, no handoffs, no guessing.

If something can be improved, we’ll tell you.
If something needs clarification, we’ll ask.
If a timeline changes, you’ll know early.

That transparency saves time, cost, and frustration.
Precision Where It Matters

We specialize in steel and aluminum parts that require tight tolerances, repeatability, and careful execution. Our processes are built around accuracy, consistency, and attention to detail — whether we’re machining a single prototype or a small production run.

Quality is built into the way we work

Creative Problem Solving

Not every part is straightforward — and that’s where we do our best work.

We regularly help customers refine designs, improve manufacturability, and solve fabrication challenges before machining begins. This collaborative approach reduces rework and leads to better outcomes.

What This Means for You
  • Parts made right the first time

  • Direct access to technical insight

  • Reasonable pricing for precision work

  • Reliable turnaround without cutting corners

If you value accuracy, communication, and thoughtful execution, 12th Dimension Industries is a strong fit.
Hands on Manufacturing by Design

We operate as an Independent Precision Workshop. That allows us to:

  • Stay extremely flexible and agile

  • Provide direct customer communication

  • Maintain high accountability and quality focus

  • Foster a sense of community both internally and with our customer

If a project fits our capabilities, we’ll treat it with care. If it doesn’t, we’ll be honest about it.

Automotive

We support automotive projects from development through production, with a focus on repeatability and production awareness. Our manufacturing process is designed to deliver consistent results as requirements and volumes evolve.

How We Work

A Clear, Thoughtful Process

We keep our process simple, transparent, and engineering-driven. Every project is handled with the same attention to detail — from initial review through final delivery.

What You Can Expect
  • Direct communication with the people making your parts

  • Honest feedback and realistic timelines

  • Careful execution with attention to detail

  • A shop that takes responsibility for its work

1. Review & Understanding

We start by reviewing your design, requirements, and constraints. If something looks unclear or can be improved, we’ll flag it early. Our goal is to fully understand design intent before machining begins.

2. Feedback & Quoting

Once the scope is clear, we provide straightforward feedback, realistic timelines, and fair pricing. If adjustments can improve manufacturability or reduce cost, we’ll walk through those options with you.

No surprises. No vague estimates.

3. Precision Machining

With everything aligned, we machine your parts carefully and deliberately. We focus on accuracy, repeatability, and process discipline — whether it’s a single prototype or a small production run.

Quality is built into the process, not rushed at the end.

4. Delivery & Follow-Through

Parts are delivered as promised. If there are questions, revisions, or future iterations, we stay involved and responsive.

Our work doesn’t end when the part leaves the machine.

Simple process. Serious execution.
