Capability<\/th>\nTechnical Description<\/th>\nJucheng Advantage<\/th>\n<\/tr>\n<\/thead>\n
Vapor Polishing<\/strong><\/td>\nChemical vapor treatment that melts the surface at a microscopic level to restore 100% transparency.<\/td>\nWe achieve optical-grade clarity on complex curved lenses and internal ports where manual polishing is impossible.<\/td>\n<\/tr>\n
Micro-Milling Light Guides<\/strong><\/td>\nMilling fine grooves and prisms for light refraction with extremely small step-overs.<\/td>\nOur high-speed spindles (up to 30,000 RPM) ensure burr-free edges and sharp prism peaks for maximum light efficiency.<\/td>\n<\/tr>\n
Precision Diamond Turning<\/strong><\/td>\nUtilizing specialized diamond tools to achieve mirror surface finishes directly off the machine.<\/td>\nReduces post-processing time and ensures the highest geometric accuracy for spherical and aspherical lenses.<\/td>\n<\/tr>\n
Anti-Scratch Coating Prep<\/strong><\/td>\nMachining and cleaning surfaces to prepare for secondary hard-coat or anti-reflective (AR) treatments.<\/td>\nJucheng provides a clean-room style finishing environment to ensure optical parts are free from dust and contaminants.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Fabrication Guidelines for Optical Grade PC<\/h3>\n

Clarity Maintenance:<\/strong>
\nTool marks are highly visible in optical parts. Tip:<\/strong> 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.<\/p>\n

Scratch Protection:<\/strong>
\nOptical PC is relatively soft and scratches easily. Tip:<\/strong> We apply protective adhesive masking immediately after machining and keep the workspace meticulously clean to prevent surface damage.<\/p>\n

Coolant Selection:<\/strong>
\nNon-compatible coolants can turn optical PC cloudy or cause micro-cracking. Tip:<\/strong> We use only high-purity, plastic-safe water-soluble coolants or chilled air-blast cooling to maintain material transparency.<\/p>\n

Annealing for Optics:<\/strong>
\nInternal stress can distort light paths (birefringence). Tip:<\/strong> We perform strictly controlled annealing cycles to ensure the light transmission properties are uniform throughout the part.<\/p>\n<\/div>\n

Primary Applications<\/h3>\n

Automotive Lighting<\/strong>
\nPrototype headlight lenses, interior light guides, and taillight covers requiring optical clarity and high impact resistance.<\/p>\n

Medical Diagnostics<\/strong>
\nSight glasses, flow cells, and clear reservoirs for blood analyzers where visual monitoring is critical.<\/p>\n

Aerospace & Defense<\/strong>
\nCockpit canopies, sensor windows, and camera lenses that must withstand high-speed impacts and thermal cycling.<\/p>\n

Industrial Instrumentation<\/strong>
\nPressure gauge covers, level indicators, and inspection windows for high-pressure fluid systems.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
