For manufacturers demanding micron-level accuracy in ophthalmic component machining, our monocrystalline diamond (MCD) turning tools redefine precision, surface quality, and tool longevity.
Engineered specifically for processing resin contact lenses, IOLs (intraocular lenses), and corrective optics, these tools enable unmatched production efficiency and product performance.
Critical Applications in Vision Correction Manufacturing
- Contact Lens & IOL Machining: Achieve flawless cutting/grooving of rigid gas-permeable (RGP) and soft hydrogel lens materials. The atomically sharp edge ensures crack-free surfaces and optical homogeneity, critical for corneal biocompatibility and comfort.
- High-Precision Molds: Machine mold cores with complex aspheric or multifocal curvatures (e.g., for single-vision, bifocal, or trifocal lenses). Sub-100nm waviness guarantees mold accuracy, directly translating to consistent lens power (±0.5°) and reduced rejection rates.
- Surface Finishing: Utilize diamond-tipped tools for micro-grinding and polishing lens surfaces. Achieve Ra ≤0.02μm roughness—minimizing secondary polishing and preventing irritation-causing surface defects.
- Customization Engraving: Etch patient-specific identifiers or prescription details with micron-scale clarity using ultra-fine diamond points.
Technical Advantages Driving Production Efficiency
Ultra-Low Waviness (≤80nm):
Proprietary planetary swing grinding controls tool-path waviness within an 80–100nm range across a 70° arc (R2 radius).
This ensures lens power consistency within ±0.5°—critical for meeting ISO 13485 optical tolerances.
Optical-Grade Surface Finish:
Ra 0.02μm roughness on rake/flank faces produces lenses with near-optical surfaces directly off the lathe. Reduces polishing time by >30% and preserves complex curvature integrity.
