The part you need doesn't exist. Yet.

JDA Machining is a precision fabrication studio in Kannapolis, NC. We turn sketches, specs, and broken parts into machined, welded, and inspected components that fit the first time, from a single prototype to a run of five hundred.

Sec 01 / Watch the Work

Chips, sparks, and parts coming off the machine.

No stock footage and no studio. Just real cuts on real machines in the Kannapolis shop. Watch a part take shape, then send us yours.

Sec 02 / Who Calls Us

Four problems walk through this door

If one of these sounds like your week, you're in the right place. Each one ends the same way: a finished part, built to spec.

"The OEM discontinued it."

We reverse engineer obsolete parts from the worn original, measure, model, machine. Often in a better material than the factory used.

Recreate the part →
"The catalog part almost fits."

Almost is a failure mode. We build the exact-fit version, or modify the catalog part correctly, not with a hammer.

Get the exact fit →
"It's still a sketch."

Napkin to CAD to working prototype, with honest feedback before metal gets cut. If a design won't hold up, we say so and show what will.

Prototype it →
"I need fifty more, identical."

Small-batch production with the documentation to repeat it next quarter and next year. No big-shop minimums, no lead-time games.

Plan the run →
Sec 03 / Capabilities

Six disciplines, one roof, zero hand-offs

Design support through final inspection happens in-house. You talk to the person making the part, not a ticket queue.

CNC Machining

Milling & turning: brackets, plates, fixtures, bushings, shafts, and complex one-off geometry. Big parts to fine, small parts like washers and spacers.

HAAS + Miyano →

Custom Fabrication

Cutting, forming, and assembly for frames, mounts, guards, enclosures, and the fixture nobody sells.

Built to fit →

TIG & MIG Welding

Steel, stainless, and aluminum. Structural repairs that hold and cosmetic beads that look like they should.

Hold and look right →

Prototyping & Reverse Engineering

Sketch or worn original to documented, repeatable part. In-house FDM & resin printing proves fitment before metal gets cut.

Idea in, part out →

Laser Engraving

Serial numbers, scales, logos, and traceability marks: permanent and repeatable on finished parts. 60W fiber + diode.

Marking & ID →

Firearms Accessories & Tactical Hardware

Accessory components, mounting systems, brackets, and adapters, prototype-to-production support for equipment developers.

Sec 04 / How We Work

From problem to part in four steps

You don't need CAD files or a perfect drawing to start. You need a problem worth solving and a couple of business days for the quote.

01

Send it

A spec, a sketch, a photo, the broken part, or a clear description. Any one of them is enough to start.

02

Plan it

Design review, material selection, and a straight quote. If something in the design will fail, we flag it before metal gets cut.

03

Build it

Machine, weld, fabricate, or engrave, with a direct line to the machinist if anything changes mid-job.

04

Prove it

Inspect against the spec, finish, and deliver. If it doesn't measure right, it doesn't leave.

Sec 05 / Proof, Not Promises

The work is the argument

17 yrs

Hands-on machining experience behind every job, not a number on a brochure.

100%

Of parts measured against the spec before they ship. No exceptions for rush jobs.

1 to 500

Unit range we run, documented so unit 500 matches unit 1.

Finished machined flange held at the JDA bench
Finished billet flange · machined, faced, deburred
Problem

No off-the-shelf bracket existed for the customer's engine swap. The closest catalog option needed modification and still flexed under load.

Process

Measured directly from the vehicle, modeled the part, machined 6061 billet, TIG-welded the gusset, and test-fit before delivery.

Result

A direct-fit part, stiffer than the original concept, documented and repeatable for future runs.

If it doesn't measure right, it doesn't leave.

Every part is checked against the spec before delivery. That's the whole quality policy, and it's not negotiable.

Sec 06 / Industries Served

Serious, project-based work across four verticals

01

Performance Automotive

Engine-swap brackets, hubs, adapters, and one-off fitment that off-the-shelf parts can't handle.

View →
02

Industrial Maintenance & Repair

Replacement parts, bushings, shafts, and line-down repairs for local manufacturers.

View →
03

Inventors & Small Manufacturers

Prototype to small production run, with honest design feedback and documentation.

View →
04

Firearms Accessory & Tactical Hardware

Accessory components, mounting systems, and duty-use hardware, prototype-to-production for equipment developers.
