01. Quality control

Machining quality control, from drawing to shipped part

Our machining quality control is the same on every job, from the first read of the drawing to the part in the crate. When you send a print to a shop you haven’t used, you want to know what happens to it. Here it is, step by step. The short version: we’re ITAR registered, not ISO 9001 certified, and every part is checked against your print before it ships.

The drawing is read before it is priced

A machinist reads the print before we quote it. If a tolerance, finish, thread callout or material spec is unclear, it comes back to you as a question. We don’t guess, and we don’t cut to a drawing we think is wrong. The quote, the job and the report all carry the revision you sent.

Measured where it sits

Final inspection runs on a Keyence XM-5000 portable CMM. Because it’s portable, a 170-inch shaft is measured where it sits rather than moved to a room it won’t fit in. Critical dimensions are checked at the machine during the run, and surface finish is checked on a profilometer.

One named machinist

Every job has one person accountable for it. You get their name, and you can call them.

Paperwork your way

Material certs, first article inspection and inspection reports come on request. We use our own report form, or we fill in yours.

ITAR registered

We’re registered under ITAR, so we can accept defense-related drawings and handle them as the regulations require.

The drawing is read and questioned before the job is quoted.

02. Process

Eight steps, the same on every job

From the drawing review to the crate, this is how a build-to-print job runs here.

A machinist reads the print before we quote it. If a tolerance, finish, thread callout or material spec is unclear, it comes back to you as a question. We don’t guess. The quote names the drawing revision it’s based on.

Material, operations, inspection and lead time, spelled out. We review every RFQ within one to two business days. Simple parts are quoted in one to two days, and larger jobs within a week.

Bought to the spec on your print. Material certs on request.

When you request first article inspection, the first part is fully measured against the drawing and reported before the rest of the run is cut.

Critical dimensions are checked at the machine during the run with micrometers, bore gauges and depth gauges. Surface finish is checked on a profilometer.

Parts are measured on the Keyence XM-5000 portable CMM. Because it’s portable, a 170-inch shaft gets measured where it sits and isn’t moved to a room it won’t fit in. Inspection reports on request, on our own form or on yours.

Every job has one person accountable for it. You get their name, and you can call them.

Packed for the part. Certs and reports go with it.

03. Certification

Are you ISO 9001 certified?

No. Zala Machine Co. is ITAR registered. We aren’t ISO 9001 or AS9100 certified, and we don’t claim to be.

Here’s what that means for you. If your contract flows ISO 9001 or AS9100 down to your suppliers, we aren’t the right shop for that part, and we’d rather say so now than after you’ve sent the RFQ. If you need a part made to your print, with the material certs, first article inspection and inspection reports you specify, that’s how we already run our jobs.

We’re a 17-person shop. We’ve spent our time and money on machines and measurement rather than a certification program. If that changes, this page will say so.

04. Measurement

What we measure with

Keyence XM-5000 portable CMM · profilometer · micrometers, bore gauges and depth gauges · thread gauging.

06. Common questions

Machining quality control: common questions

Can you send material certs?

Yes, on request. They ship with the part.

Do you do first article inspection?

Yes, on request. The first part is measured and reported before the run continues.

Whose inspection report form do you use?

Either. We have our own inspection report, or we’ll fill in your form if you send one.

What if the drawing has an error?

We flag it before we quote and wait for your answer. We don’t cut to a drawing we think is wrong.

Can you work to our drawing revision control?

Yes. The quote, the job and the report all carry the revision you sent.

Are you ISO 9001 certified?

No. Zala Machine Co. is ITAR registered. We aren’t ISO 9001 or AS9100 certified, and we don’t claim to be. If your contract flows either down to your suppliers, we will tell you before you send the RFQ.

Can you inspect very large parts?

Yes. Final inspection runs on a Keyence XM-5000 portable CMM, so a long shaft or a large housing is measured where it sits rather than moved to a room it won’t fit in.
