How Every Order Is Inspected Before It Ships
We are a trading company, which means the shop is our supplier and not yours. The measuring is ours to do and the result is ours to answer for. Four gates, an engineer on every order, a written update every week, and a report that travels with the parts.
Four gates
Where an order gets checked, in the order it happens.
Drawing read before it is placed
The engineer reads the title block first: general tolerance class to JIS B 0405, geometrical class to JIS B 0419, projection symbol. Then the grade and what the certificate has to name, the finish marks including legacy triangles, threads, treatment and any heat treat sequence. Gaps come back to you before anyone cuts metal.
Shop audited before it sees your work
A shop enters the network after we have stood on its floor: machines against the list, measuring instruments and their calibration, the grades it runs every week, and what it does with a part that fails. Then a trial order of our own before anything of yours goes near it.
In-process checks during the run
First article on the production setup, measured against every dimension on the drawing. Critical features are checked at intervals through the run, because austenitic stainless work hardens and a dimension that drifts is caught while there is still time to correct it.
Final inspection before packing
Parts are measured again before they are packed. Dimensions, surface finish where it is called out, thread gauging where the drawing asks for it. Anything out of tolerance stays here. The report goes in the box.
One engineer, start to finish
The engineer who reads your drawing is the engineer who places the order, agrees the schedule with the shop, checks the material before it is cut, reviews the first article, visits the floor while the run is on, and signs off the final inspection. There is no handover between a sales desk and a production desk, because there is no sales desk.
Every week you get a written update from that engineer: the stage, the date it is tracking to, and what changed. A photograph of your parts on the machine is worth more than a status line, so you often get one.
What ships with your parts
- Inspection reportMeasured values against the critical features on your drawing. A seisekisho in the Japanese format on request.
- Mill sheet or certificateA JIS mill sheet or an EN 10204 3.1 certificate where you asked for it, naming the standard the drawing calls for.
- Treatment recordPassivation or electropolishing to the named standard, with the processor record where one is issued.
- Packing list and photographsYour purchase order number inside and outside the box, and photographs of the packed goods before they leave.
Which report is standard on every order is being finalised. Until it is, your quote states exactly what you get rather than this page guessing.
A managed network, not a list of contacts
A shop joins the network after our engineer has stood on its floor: machines against the list, measuring instruments and their calibration records, the grades it runs every week, and what it does with a part that fails. Then a paid trial order of our own, before anything of yours goes near it. It stays in the network on performance.
We do not publish the names of the shops and we do not pass your name to them. The order sits with us at every step.
Measurement in the network
- CMMFor position, profile, flatness and anything a hand tool cannot prove. Specified per job, because not every part needs it and not every shop has one.
- Micrometers, bore gauges, height gaugesThe daily instruments. What matters is that they are calibrated and that someone records the readings.
- Thread gaugesGo and no-go to the JIS B 0209 class on the drawing. A thread called out with a class is gauged, not eyeballed.
- Surface roughness testerFor Ra callouts. A finish specified on the drawing is measured, not judged by eye, and electropolished parts are measured after polishing.
- Hardness testerWhere SUS420J2, SUS440C or SUS630 carry a hardness or ageing condition.
A tolerance nobody can measure is a tolerance nobody can prove, which is why the equipment question decides which shop gets your part.
Questions about quality
What inspection comes with an order?
Every order ships with an inspection report covering the critical features on your drawing, with measured values. A seisekisho in the Japanese format, a full dimensional report, a mill sheet or a 3.1 certificate are quoted in when you ask for them on the quote request. The standard report that ships with every order is being confirmed, so your quote states exactly what you get.
Who is responsible if a part is out of tolerance?
We are. You bought the parts from us, not from the shop, so you never negotiate with a factory in another country. We measure before packing so it should not reach you, and the remedy if it does is written on your quote and in our terms of sale.
Are you ISO 9001 certified?
SUS CNC does not hold a quality certification and will not imply otherwise. Shops in the network may be certified, and we do not trade on their certificates. What we can show you is how a shop is audited before it sees your work, the engineer who follows your order, the weekly update, and the inspection report that ships with your parts.
Can a third party inspect before shipment?
Yes. Name the inspection company on the quote request and it is scheduled into the lead time. It does not replace our own inspection before packing.
What does the weekly update contain?
The stage the order is at, the date it is tracking to, and anything that has changed: material in, first article measured, run progress, outside process sent and returned, final inspection, packed. If a date is at risk you hear it the day we know, not on the ship date.
