If you've worked with a machine shop before, you know the frustrating version of this story: a part comes back close, but not quite right. A dimension is off. A tolerance was misread. Now you're waiting on a second run — burning time and budget you didn't plan for.
At Promet, "First-Time-Right" isn't a slogan — it's the process we built to make that scenario the exception, not the norm. Here's how it actually works.
1. Design Review
Before a single tool touches material, we review your CAD files closely. This is where we catch the issues that cause rework later: features that are difficult or impossible to machine as drawn, tolerances that don't match the part's actual function, or material choices that could be optimized. Catching these early means no surprises — and no added cost — once machining begins.
2. CAM Programming
Our programmers translate your design into optimized toolpaths using advanced CAM software. This step determines efficiency and precision simultaneously: the right approach cuts cycle time without cutting corners on accuracy.
3. Setup & Calibration
Every job starts with meticulous machine setup and calibration using precision measuring instruments. This is the step that's easy to rush and expensive to skip — accuracy from the first cut depends on getting the setup exactly right, every time.
4. Precision Machining
With design, programming, and setup locked in, our CNC equipment executes the part to tolerances as tight as ±0.0005", monitored in real time throughout the run. This is where the earlier steps pay off — because the groundwork is already done, execution is consistent and predictable.
5. Quality Inspection
Every part is verified using CMM (Coordinate Measuring Machine) inspection and Statistical Process Control (SPC) analysis. We're not just checking that a part "looks right" — we're confirming it meets every dimension on the print, with full documentation to back it up.
6. Delivery
Parts are carefully packaged and delivered on schedule, with complete documentation and certificates of conformance included. No loose ends, no follow-up requests for paperwork you should have had from day one.
Why This Matters for Your Project
Whether you're machining a single prototype or a full production run, First-Time-Right means the same thing: fewer delays, fewer surprises, and parts that work the way you designed them — the first time they come off the machine.
We work across aerospace, medical device, automotive, and hardware startup projects, and this process scales the same way for a one-off prototype as it does for a 500-part production run.
