Q14: What’s the tolerance ?

Update Time:2026/4/1

FELIX GLASS is committed to providing world-class precision processing capabilities for optical glass, optical components, and display glass products. Our processing strength lies in our advanced equipment, professional technical team, and strict quality management system. The following is a detailed introduction to our overall processing capability:

1. Processing Range & Parameters

We have a wide processing range to meet diverse customer needs:

- **Size Range**: We can process glass with diameters ranging from **5mm to 300mm** and thicknesses from **0.3mm to 20mm**.

- **Shape Capability**: We support standard shapes (round, square, rectangle) as well as custom special shapes (irregular curves, arcs, domes, etc.).

- **Tolerance Control**: We maintain an ultra-high precision tolerance of **±0.01mm** for dimensional requirements, ensuring consistency in mass production.

- **Surface Quality**: The surface roughness (Ra) can reach **<0.012μm**, meeting the highest standards for optical applications.

2. Core Processing Equipment

Our processing capability is supported by a full set of high-end equipment:

- **Precision CNC Processing Centers**: Imported from leading manufacturers, these machines enable high-precision cutting, drilling, and grinding of glass materials. They ensure stability and accuracy even for complex custom orders.

- **High-Precision Polishing Machines**: We use computer-controlled polishing (CCP) technology to achieve ultra-smooth surfaces, which is crucial for optical performance.

- **Advanced Vacuum Coating Machines**: Our coating equipment allows for the application of AR, AG, AF, and HR coatings with precise thickness control (±1nm), ensuring consistent performance.

3. Process Capability

We are capable of handling a complete processing chain:

- **Raw Material Incoming**: Strict inspection of raw glass to ensure internal quality and stability.

- **Precision Machining**: Cutting, slicing, drilling, and edge processing with minimal stress and deformation.

- **Surface Finishing**: Precision polishing, grinding, and lapping to achieve the required surface finish.

- **Surface Coating**: Multi-layer coating technology to enhance optical properties.

- **Final Inspection**: 100% inspection using precision measuring instruments (like laser scopes and interferometers).

4. Complex Custom Order Processing

We have strong expertise in processing complex optical components:

- **Optical Domes**: Process BK7/K9/Sapphire domes with high precision for automotive and sensor applications.

- **Curved Glass**: Process bent/curved glass for automotive displays and industrial screens with consistent curvature.

- **Special Optical Lenses**: Custom plano-convex, plano-concave, and aspheric lenses for thermal imaging and CO2 lasers.

5. Capacity & Lead Time

- **Monthly Processing Capacity**: We can process over 50,000 pieces of standard optical glass and 10,000 pieces of complex custom components monthly.

- **Lead Time**: Standard orders take 3-7 days, while complex custom orders take 7-15 days. For urgent orders, we offer expedited processing services.

At FELIX GLASS, we continuously invest in technology and equipment to improve our processing capability. We aim to provide reliable, high-precision processing services to support your high-end projects. If you need a flow chart of our processing workflow, please contact our sales team.
