18 Jul Quality Assurance at Mainstream: How Coordinate Measurement Machines Keep Our Standards High
In precision manufacturing, the difference between a perfect part and a failed one can be just a few microns. At Mainstream, we know that accuracy isn’t just a value. It’s a promise. And behind that promise is a powerful piece of technology: the coordinate measurement machine or CMM.
It’s not just about inspection. It’s about trust, performance and long-term reliability, especially when we’re delivering mission-critical components for aerospace, defense or medical applications.
The Moment We Knew CMMs Were Non-Negotiable
Years ago, one of our aerospace clients needed a run of high-tolerance components: thin, lightweight parts that would function in extreme environments. The tolerances were tight. The material wasn’t forgiving. And the consequences of failure? Potentially catastrophic.
Rather than relying on post-process spot checks, we brought the project into our closed-loop quality system, incorporating full inspections with a coordinate measurement machine at key stages of production. The result? A 100% acceptance rate and a long-term partnership that still exists today.
That experience reaffirmed what we already believed: CMMs aren’t optional. They’re essential.
What Is a Coordinate Measurement Machine?
A coordinate measurement machine is an advanced inspection tool used to verify the dimensional accuracy of machined parts. The CMM records the X, Y and Z coordinates of features on a part’s surface using a high-precision probe. This data is then compared to a digital model or blueprint to make sure everything is within specified tolerances.
Unlike traditional measuring tools, CMMs:
- Detect even the smallest deviations
- Offer repeatable, automated measurements
- Integrate directly into digital quality systems
- Create traceable documentation for customer audits and compliance
How We Use CMMs at Mainstream
At Mainstream, CMM inspection is integrated into our process from start to finish instead of being used as a final check. This provides consistent accuracy and reduces the risk of costly rework or delays.
Our CMMs allow us to:
- Validate complex 5-axis and Swiss CNC machined parts
- Run first article inspections and generate reports for customer validation
- Perform in-process checks during production runs
- Ensure compliance with AS9100D, AS13100, and ISO 9001:2015 standards
From aerospace hardware to tactical defense components, we use our coordinate measurement machines to verify that every feature is exactly where it needs to be.
Why It Matters to You
If you’re sourcing high-precision parts, you’re not only buying metal, you’re buying confidence as well.
You need to know:
- Your parts were measured, verified and documented
- Your supplier can consistently meet tight tolerances
- Your project won’t be delayed due to poor inspection practices
That’s what our CMM capabilities offer.
