Monocrystalline Diamond Turning Tools for Optical Mold Cores
Our precision-engineered monocrystalline diamond (SCD) cutting tools are dedicated to machining optical mold cores with sub-micron accuracy.
These tools deliver exceptional wear resistance and mirror-finish surfaces, meeting stringent requirements for imaging applications (e.g., mobile camera molds) and non-imaging components (e.g., LED reflectors).
In high-precision optical manufacturing, the quality of mold cores directly determines the performance of final optical components. Our monocrystalline diamond (SCD) turning tools provide the critical edge technology for machining these demanding substrates.
Application-Specific Engineering
We classify optical mold cores into two categories with distinct tooling requirements:
1. Imaging Mold Cores
- Applications: Mobile camera molds (highest precision), automotive/TV lens molds
- Tool Specifications:
- Dominant edge radius: R0.05 (mobile), R0.1 (auto/TV)
- Key materials: Nickel-plated steel, nickel-plated copper
- Performance Focus: Surface finish consistency for distortion-free imaging
2. Non-Imaging Mold Cores
- Applications: LED diffusers, flash reflectors (light control applications)
- Tool Specifications:
- Optimized edge radius: R0.01–R0.02
- Performance Focus: Efficient light management with reduced micron-level artifacts
Monocrystalline Diamond Turning Tools: Core Technical Advantages
- Material Superiority:
Single-crystal diamond structure delivers industry-leading hardness and wear resistance, extending tool life during continuous nickel-alloy machining.
- Nano-Scale Edge Precision:
Laser-aligned cutting edges achieve micron-level sharpness (R0.01–1mm customizable) for chip-free, sub-micron finish surfaces.
- Flawless Surface Integrity:
Mirror-polished facets with zero microscopic defects (verifiable under 400× microscopy), enabling Ra<0.02μm optical surfaces.
Custom Geometry Solutions
- Edge Radius: R0.01–1.00mm
- Rake Angle: 0° (standard)
- Clearance Angle: 12°–18°
- Included Angle: 15°–45°
Geometry optimization is available for specific substrate/workpiece configurations.
