How Liberty Precision Delivers Excellence Through Quality Inspection
In advanced manufacturing, delivering complex, tight-tolerance parts isn’t just about how well you can machine—it’s about how well you can measure. At Liberty Precision, quality inspection is an essential, integrated part of our commitment to delivering flawless results across industries like aerospace, defense, and medical.
From advanced tools to a team dedicated to continuous learning, Liberty’s approach to quality control is unmatched, and the results speak for themselves.
Learning Never Stops at Liberty: The Foundation of Quality
At the core of our approach to quality inspection is a strong belief in lifelong education. We understand that even the most cutting-edge equipment is only as powerful as the people using it. That’s why we continually train and upskill every team member, whether they’re programming coordinate measuring machines (CMMs) or running checks on the floor.
Every machinist at our precision machine shop is trained to use inspection tools, reducing bottlenecks and boosting autonomy. And to ensure expertise stays sharp, we’ve designated three inspection programming specialists who help implement new technologies and workflows across the shop floor. The result? Fewer delays, faster approvals, and more confident customers.
The Tools That Set Us Apart
To support our world-class CNC machining services, we’ve invested heavily in inspection technology that outpaces competitors. Our lab and shop floor feature an arsenal of tools to verify that even the most complex machining projects meet exact specifications:
2 ZEISS DURAMAX CMMs – portable for shop floor use, enabling on-the-spot verification
1 ZEISS CONTURA CMM – for highly accurate part inspection
2 KEYENCE IM-8000 systems – optical comparators that accelerate inspection times dramatically
2 Mitutoyo skidless profilometers – for surface finish analysis
1 ZEISS SURFCOM – added in 2023 for detailed surface measurement
1 ZEISS RONDCOM – ensures perfect diameter cylindricity
1 hardness tester – for mechanical property validation
3 traditional comparators – enhancing versatility for visual inspections
We’ve chosen ZEISS equipment for much of our inspection work due to the powerful and versatile CALYPSO software, which allows one program to run across multiple devices. That streamlines our machining services and reduces redundancies, especially in high-mix environments.
Proven Results, Backed by Technology
We believe quality inspection should move at the speed of production, and thanks to our equipment and trained team, it does. For one agricultural OEM part, our KEYENCE systems helped reduce a typical inspection process from two minutes to just 15 seconds per part—and that level of time savings can quickly add up!
The outcome? Faster throughput, fewer delays, and superior service.
And when you consistently deliver excellence, trust follows. One of our aerospace clients now waives incoming inspections altogether. That’s because over the last three years, we’ve maintained a flawless zero defects per million (DPM) record across millions of parts shipped. It’s one more reason Liberty is a preferred AS9100D-certified machine shop for so many aerospace manufacturing projects.
Looking Ahead: AI and the Next Generation of Inspection
Liberty Precision isn’t just focused on what inspection looks like today; we’re actively investing in what’s next. Our long-term vision includes integrating artificial intelligence into our inspection workflow. By enabling AI to write inspection programs based on past data and specs, we aim to:
Automate First Article Inspection processes
Feed real-time data into SPC charts
Reduce lead times and manual intervention
Enhance accuracy and repeatability
This next chapter will further strengthen our ability to deliver efficient, scalable, and repeatable results across our contract manufacturing services.
