ISO 9001 for Machine Shops

Why this keeps landing on your desk

It's almost never regulation. It's a purchasing manager somewhere with a vendor questionnaire that has a box for "ISO 9001 certified?" Aerospace primes, medical OEMs, and the energy majors all push their quality requirements down the supply chain, and regular OEMs are following. No checkbox, no RFQ. One contract usually covers the whole cost of getting certified, several times over.

What it actually takes for a 10-30 person shop

• You already do more of this than you think. Job travelers, first articles, calibration stickers, packing slips. Those are quality records. ISO 9001 mostly asks you to make what you already do consistent and provable.
• The documentation is smaller than the horror stories. A modern small-shop QMS is a lean quality manual, a dozen or so procedures, and forms you mostly already use. The 500-page binder era is over. Auditors flag bloat as a weakness now.
• The real work is habits, not documents: actually logging nonconformances, actually closing corrective actions, actually calibrating on schedule. That takes 3-4 months of practice, which is why the timeline is what it is.
• One point person, a few hours a week. Not a hire. If nobody can spare the hours, that's what a fractional quality manager is for.

Common objections, answered straight

"We're too small for ISO."

Shops of 4 people hold certificates. The standard scales. A 10-person shop's system should look nothing like an aerospace prime's, and an auditor who expects otherwise is a bad auditor. We help you pick registrars whose auditors actually work small shops.

"It's just paperwork that slows the shop down."

Badly built systems are. A good one writes down what your best machinist already does so the new guy does it too. If a procedure slows the shop and doesn't prevent a defect or defend you in an audit, it shouldn't exist.

"We tried a template kit and it died."

We hear this one a lot. Templates describe a fictional company, nobody recognizes their own shop in them, and the binder gathers dust. Systems survive when they're written around your travelers, your routers, and your actual flow. That's the job.

"What about AS9100? The aerospace RFQs mention it."

AS9100 is ISO 9001 plus aerospace requirements. If aerospace work is on your horizon, we build the ISO 9001 core with the AS9100 upgrade path in mind so nothing gets rewritten later.

What it costs a machine shop

Gap analysis is fixed at $1,000-$2,500. Registrar fees typically run $4-9K initial for shops this size. Implementation gets quoted firm after the gap analysis. The full cost breakdown is here.
