Ultra-Precision Machining of Hard and Brittle Quartz Substrates
Understanding material purity, crystallographic thermal stability, and mechanical micro-chipping suppression during high-speed CNC milling and ultrasonic grinding.
Thermal & Dielectric Integrity
High-purity quartz boasts a minimal coefficient of thermal expansion (CTE ≈ 5.5 × 10⁻⁷ /°C from 20°C to 320°C), preventing micro-deformation under intense laser radiation and semiconductor thermal cycles up to 1,150°C.
Sub-Surface Damage (SSD) Control
By employing diamond-coated multi-axis CNC tooling with ultrasonic agitation (USM), brittle micro-fracturing is reduced to depths under 2 µm, paving the way for optical fire-polishing and peak chemical etching endurance.
Broadband Spectral Transparency
From deep-UV (DUV at 193 nm) up through mid-infrared (3,500 nm), custom doping (Samarium, Cerium) and low-hydroxyl grades deliver peak transmission efficiency and tailored spectral isolation for medical and analytical instruments.
Hermetic & Chemical Inertness
CNC machined fused silica shows extreme chemical resistivity across fluorine and chlorine-based plasma etch chambers, providing long operating lifespans without metal ion contamination or surface devitrification.
| Quartz Material Grade | Transmission Bandwidth | Hydroxyl (OH⁻) Content | Primary Industrial Application | Typical CNC Tolerances |
|---|---|---|---|---|
| JGS1 (Synthetic Fused Silica) | 185 nm – 2,500 nm (DUV / UV) | < 5 ppm to 1,200 ppm | Semiconductor Lithography, Laser Optics, DUV Windows | ± 0.005 mm / Ra 0.2 µm |
| JGS2 (Fused Quartz / Natural) | 220 nm – 2,500 nm (Standard Optical) | < 30 ppm to 150 ppm | Laser Cavities, Sight Glasses, Semiconductor Quartzware | ± 0.010 mm / Ra 0.4 µm |
| JGS3 (Infrared Fused Quartz) | 260 nm – 3,500 nm (Extended IR) | < 2 ppm (Low-OH) | Infrared Pyrometry, Medical Lasers, Heat Viewports | ± 0.010 mm / Ra 0.4 µm |
| Samarium / Cerium Doped Quartz | Cut-off UV (< 380 nm or < 400 nm) | Application Doped | IPL Cosmetic Handles, Flashlamp Envelopes, Solid-State Lasers | ± 0.020 mm / Bore ± 0.01 mm |
The Strategic Advantage of China's Advanced Quartz Manufacturing
How Tianjin BY Photonics unites raw ingot synthesis, cold CNC grinding, and hot flame craftsmanship to drive down lead times and capital costs for global Tier-1 OEMs.
Vertically Integrated Processing
Eliminating external subcontracting risk by uniting precision 5-axis CNC roughing, double-sided optical lapping, oxyhydrogen glassblowing, and capillary redrawing in one 3,000 m² standardized facility.
Raw Ingot Supply Chain Dominance
Direct raw material procurement from primary quartz synthesis bases enables constant inventory of high-purity JGS1/JGS2/JGS3 and optical glass, hedging global volatility and reducing lead times by up to 45%.
Rapid Prototype to Volume Scaling

Ultrasonic-Assisted Milling
Kinematic vibration superimposed on diamond cutting tools reduces cutting force by over 40%, eliminating edge edge-chipping during complex micro-channel milling.
Atmospheric Thermal Fire-Polishing
Controlled oxyhydrogen flame heating heals residual micro-cracks on machined surfaces, restoring optical clarity and increasing mechanical flexural strength against thermal shocks.
Cleanroom Cleaning & Vacuum Sealing
Ultrasonic solvent cleaning, DI water rinsing (>18 MΩ·cm), and cleanroom Class 100 particle-free vacuum packaging prevent surface ionic contamination before cleanroom assembly.

Frequently Asked Technical & Sourcing Questions
Direct answers from our senior fabrication engineers on CAD drawings, material selection, tolerances, and custom quartz CNC machining capabilities.
What is the key difference between JGS1, JGS2, and JGS3 quartz glass?
JGS1 is a high-purity synthetic fused silica offering premier transmission across the deep-UV spectrum down to 185 nm, making it suitable for lithography and laser optics. JGS2 is natural fused quartz engineered for standard optical and visible windows down to 220 nm. JGS3 is vacuum-fused infrared-grade quartz with hydroxyl (OH⁻) content below 2 ppm, eliminating the water absorption band at 2.73 µm to provide clear transmittance up to 3,500 nm.
What dimensional tolerances can Tianjin BY Photonics achieve on CNC quartz parts?
For high-precision CNC turned and milled components, we routinely hold outer and inner diameter tolerances within ± 0.005 mm, surface flatness up to λ/10 @ 632.8 nm, parallelism down to < 5 arcseconds, and surface scratch-dig standards of 20-10 or 10-5 depending on drawing requirements.
How do you mitigate subsurface micro-cracks and stress during machining?
We combine rough diamond abrasive grinding with high-frequency ultrasonic machining (USM) and multi-step fine grit lapping. Furthermore, parts undergo specialized thermal annealing cycles in precision electric furnaces to release mechanical stress, followed by oxyhydrogen flame fire-polishing to seal micro-fissures on edges and holes.
Which CAD formats are preferred for manufacturing review?
We accept 3D solid models in STEP (.stp) and IGES (.igs) formats, coupled with 2D drawings in DXF, DWG, or dimensioned PDFs highlighting GD&T callouts, surface roughness (Ra), cosmetic scratch-dig tolerances, and critical inspection datums.
Can you customize samarium-doped and cerium-doped quartz tubes for laser cavities?
Yes. We machine and draw custom-diameter single-bore, double-bore, and triple-bore flow tubes infused with Samarium (Sm³⁺) or Cerium (Ce⁴⁺). These dopants attenuate parasitic laser oscillation at 1064 nm and suppress 200–380 nm UV emissions to prevent solarization of laser crystals and protect organic coolant media.
What is the standard production lead time for prototype and wholesale orders?
Custom prototype orders typically ship within 7 to 14 business days following engineering DFM sign-off. High-volume repeat wholesale orders are manufactured under scheduled blanket PO deliveries or fulfilled within 3 to 4 weeks, backed by dedicated raw quartz ingot inventory reserves.
