Optical Grade PC Machining Capabilities

Возможность Техническое описание Преимущество Jucheng
Парофазная полировка Chemical vapor treatment that melts the surface at a microscopic level to restore 100% transparency. We achieve optical-grade clarity on complex curved lenses and internal ports where manual polishing is impossible.
Micro-Milling Light Guides Milling fine grooves and prisms for light refraction with extremely small step-overs. Our high-speed spindles (up to 30,000 RPM) ensure burr-free edges and sharp prism peaks for maximum light efficiency.
Precision Diamond Turning Utilizing specialized diamond tools to achieve mirror surface finishes directly off the machine. Reduces post-processing time and ensures the highest geometric accuracy for spherical and aspherical lenses.
Anti-Scratch Coating Prep Machining and cleaning surfaces to prepare for secondary hard-coat or anti-reflective (AR) treatments. Jucheng provides a clean-room style finishing environment to ensure optical parts are free from dust and contaminants.

Fabrication Guidelines for Optical Grade PC

Clarity Maintenance:
Tool marks are highly visible in optical parts. Совет: We use a very small step-over (0.05mm or less) during the finishing pass to minimize tool lines, making the subsequent vapor polishing process more effective.

Scratch Protection:
Optical PC is relatively soft and scratches easily. Совет: We apply protective adhesive masking immediately after machining and keep the workspace meticulously clean to prevent surface damage.

Выбор охлаждающей жидкости:
Non-compatible coolants can turn optical PC cloudy or cause micro-cracking. Совет: We use only high-purity, plastic-safe water-soluble coolants or chilled air-blast cooling to maintain material transparency.

Annealing for Optics:
Internal stress can distort light paths (birefringence). Совет: We perform strictly controlled annealing cycles to ensure the light transmission properties are uniform throughout the part.
