Customized CNC Solutions for High-Tolerance Optics & Precision Instruments

Imagine you’re designing a satellite lens or a surgical laser component. You need tolerances under ±1.5µm, exotic materials like Zerodur®, and a supplier who won’t force you to choose between speed and precision. At PFT, we get it. That’s why our custom CNC machining for high-tolerance optics isn’t just about cutting metal—it’s about enabling breakthroughs .

Why Precision Isn’t Optional in Optics & Instruments

In aerospace, medical tech, or semiconductor manufacturing, sub-micron inaccuracies cause system failures. A misaligned mirror in a space telescope or a flawed lens in an endoscope can cost millions. Our clients demand:

•   Nanometer-level accuracy for chip fabrication optics 
•   Non-contact measurement to prevent delicate surface damage 
•   Custom geometries for bespoke R&D projects 
That’s where our solutions shine.

How We Deliver: Your Factory’s Core Strengths

1. Advanced Equipment Built for Microscopic Precision

Our workshop runs 5-axis CNC machining centers with liquid-cooled spindles (±0.1°C thermal control) to eliminate tool drift during 48-hour cuts . For ultra-fine optics, we deploy:

•   Deterministic polishing systems for surface roughness < 5Å 
•   3D contour scanners to map lens curvature in real-time 
•   German-engineered OPTIMUM TC 62RC probes for tool calibration at ±0.5µm 

2. Zero-Compromise Process Controls

We don’t just machine parts—we engineer reliability:

•   AI-powered optical imaging: Detects subsurface flaws invisible to human inspectors .
•   SPC (Statistical Process Control): Every batch generates automated reports tracking 65+ parameters (e.g., flatness, coaxiality) .
•   Material science rigor: From titanium alloys to CVD silicon carbide, we’ve mastered stress-relieving heat treatments to prevent post-machining distortion .

3. Quality Control That Exceeds ISO 9001

Your surgical laser or satellite sensor deserves traceability down to the raw material lot:

•   CMM + laser interferometry: Validates dimensions to ±0.8µm .
•   Cleanroom assembly: Class 1000 environments for contamination-sensitive optics .
•   Compliance documentation: Full GD&T reports, material certs, and 3D scan archives .

4. One-Stop Capabilities: From Prototypes to Volume Production

Whether you need 10 custom collimators or 10,000 precision instrument housings, our flexible cells handle:

•   Optical components: Aspheric lenses, mirror substrates, prism assemblies 
•   Precision mechanical parts: Sensor mounts, actuator housings, micro-fluidic devices 
•   Materials mastery: Aluminum, brass, Invar®, fused silica, PEEK 

5. After-Sales: Partnership Beyond Delivery

A cracked coating or an unexpected tolerance shift? Our support includes:

•   24/7 technical hotline with on-call engineers 
•   Free recalibration for legacy parts (up to 5 years post-delivery) 
•   Rapid-response prototyping: 72-hour turnaround for design adjustments 
•   Aerospace Client: Reduced satellite mirror alignment errors by 90% using our high-precision CNC optical grinding for SiC substrates. Result: 20% lighter payload, mission lifespan extended. 
•   Medical OEM: Eliminated post-sterilization distortion in endoscope barrels via our stress-relieved titanium machining. Result: 0.02% field failure rate.
