Custom Precision Machined Quartz Glass Sheet-sara
게시일: June 22, 2026
Case Overview
This cooperation case focuses on mass customized quartz glass sheets with dense precision holes for an overseas optical testing equipment manufacturer. The customer needed high-transmittance fused silica substrates with uniform hole arrays, strict dimensional tolerance and high thermal shock resistance for UV light detection and high-temperature testing equipment.
We provided full one-stop customization including raw material grade selection, CNC laser drilling, flame polishing, edge chamfering and stress relief annealing, completely solving the customer’s troubles of glass cracking, hole edge chipping, low light transmittance and unstable dimensional consistency.
Client Pain Points Before Cooperation
- Ordinary glass substrates cracked frequently under long-term 900℃ working temperature, poor thermal shock resistance, high replacement cost.
- Conventional drilling process caused burrs and micro-cracks around holes, affecting optical transmission and test accuracy.
- Uncontrolled flatness tolerance, uneven hole spacing, unable to match customer’s precision fixture.
- Low-purity glass material contained bubbles and impurities, resulting in UV light attenuation and unstable experimental data.
Our Customized Quartz Glass Sheet Solution
- High-Purity Material Selection
Adopt JGS1 ultra-transparent synthetic fused silica with low hydroxyl content, no bubbles, no impurities, excellent UV & infrared light transmittance, fully meet optical grade standards.
- Precision Laser CNC Drilling
Advanced femtosecond laser drilling process, hole diameter tolerance controlled within ±0.01mm, neat hole edge without chipping, no micro-cracks inside the glass. Support single hole, dense hole array, special-shaped hole layout as per customer drawings.
- Full Surface Flame Polishing
Inner & outer surfaces fully flame polished, ultra-smooth flatness, high light transmittance, no scratches, low light loss during optical testing.
- Stress Relief Annealing Treatment
All finished quartz sheets go through high-temperature annealing to eliminate internal stress, effectively prevent cracking under repeated cold & hot cycles.
- Multi-Shape Customization
Support square, rectangular, round disc, special irregular shape; customizable thickness, chamfer, step surface, through holes & blind holes.
