Customer Success Stories
We showcase how we assisted industry leaders in aerospace, medical, automotive, and defense, solving their most complex problems in precision manufacturing.
Titanium Turbine Brackets for Commercial Aircraft
A leading aircraft engine manufacturer required ±0.0005" to 200 titanium turbine mounting brackets. Their previous supplier managed to achieve only 78% yield and 16-week lead times.
We utilized 5-axis simultaneous machining with custom fixtures, optimized tool paths for Ti-6Al-4V, and included in-process CMM inspection. Our DFM analysis found 3 design changes that cut machining time 22%.
They didn't just meet our specifications—they helped us improve our design. Their DFM suggestions enhanced part performance while cutting costs by 40%.
Surgical Robot Joint Components with Micron Precision
One of the surgical robotics companies was looking for articulating joint components with ±0.0002" (5 micron) tolerance for neurosurgery robots. 12 suppliers previously failed to meet these requirements.
We integrated Swiss-style micromachining on Citizen Cincom lathes with wire EDM for internal channels coupled with lapping for Ra 0.2μm mirror finish.
They became an extension of our engineering team. Their documentation was so thorough that FDA reviewers specifically praised our manufacturing validation.
Aluminum Battery Enclosures for EV Platforms
An EV startup needed a manufacturing partner who could keep pace with weekly design changes while scaling from prototypes to 5,000 units/month production.
We established a dedicated 24/7 prototype cell with digital twin simulation. Our modular fixturing system accommodated 23 design iterations in 3 months.
This startup design model was new to most suppliers. They wanted us to freeze our design first. They understood that in a startup, the design is never frozen until it ships.
Precision Actuator Housings for Collaborative Robots
A German robotics company wanted US-based manufacturing that matches European quality standards with 3-week lead times instead of 12 weeks from Germany.
We CMM scanned and reverse-engineered their parts. Then, we developed a single-setup 5-axis machining process that achieved Cpk 2.1, exceeding their 1.67 requirement.
I was skeptical an American shop could match German quality. I was wrong. Their process control is more sophisticated than what we had in Europe.
Ultra-Clean Wafer Handling Components
In the Semiconductor the industry, a single speck of dust can ruin a $50,000 wafer, therefore the industry operates under stringent particle count regulations. Requirements include <10 particles/cm², 0.0001" flatness over 12", and Ra 0.1μm electropolish finish.
An ISO Class 5 cleanroom machining cell with DI water coolant systems, precision grinding, and in-house electropolishing with 100% particle verification.
Their particle counts are consistently 50% below our limits. They truly understand semiconductor cleanliness requirements.
Mission-Critical Guidance System Housings
Guidance system housings must perform from -55°C to +125°C while withstanding severe vibration. Inconel 718 with ±0.0005" tolerance and ITAR compliance required.
We leveraged our ITAR-registered facility with specialized Inconel machining, multi-stage thermal stabilization, and secure documentation. Parts passed all MIL-STD-810G testing.
In 20 years of defense manufacturing, this team's attention to detail puts them in the top tier. They're now on our strategic supplier list.
