Introduction<\/h2>\n\n\n\n

Challenges in processing 3D-Coated Optical Lenses As AR\/VR devices, automotive HUDs, and high-end imaging systems evolve, the demand for 3D-coated optical lenses has surged. These coatings \u2014 often multi-layer dielectric or functional films (such as ITO, SiO\u2082, or MgF\u2082) \u2014 are extremely sensitive to mechanical stress and thermal effects.<\/p>\n\n\n\n

Traditional cutting methods, including grinding, reciprocating diamond wire, or laser cutting, frequently cause coating delamination, microcracks, or thermal damage, reducing yield and increasing polishing costs.<\/p>\n\n\n\n

To address these challenges, Vimfun developed the Endless Diamond Wire cutting system<\/a>, designed for precision optical applications. Its closed-loop endless structure ensures constant speed, stable tension, and uniform cooling \u2014 eliminating coating damage at the source.<\/p>\n\n\n\n

Test Setup and Parameters<\/h2>\n\n\n\n

A controlled comparison test was conducted to evaluate Vimfun\u2019s endless diamond wire in cutting 3D-coated optical lenses.<\/p>\n\n\n\n

Material: 3D-coated optical glass lens (\u230030 mm, coating thickness \u22481.5 \u03bcm, multilayer dielectric film).<\/p>\n\n\n\n

Equipment: Vimfun Endless Diamond Wire Cutting Machine (Model SGI20<\/a>).<\/p>\n\n\n\n

Cutting Parameters: wire speed 50m\/s, feed rate 0.3 mm\/min, tension 150 N, deionized water coolant.<\/p>\n\n\n\n

Cutting request: protect the 3D layer do not damaged by heat or cutting force.<\/p>\n\n\n\n

Test Results and Observations<\/h2>\n\n\n\n

Across multiple trials, Vimfun\u2019s endless diamond wire demonstrated smooth, vibration-free cutting. The 3D coatings remained fully intact \u2014 no peeling, cracking, or surface scratches were observed.<\/p>\n\n\n\n

Surface roughness and yield results:<\/p>\n\n\n\n

microscopic picture of Vimfun cut edges<\/p>\n\n\n\n

Microscopic analysis shows that the reciprocating cut samples exhibited minor coating chipping at the edges, while the Vimfun endless wire produced clean, continuous coating edges. Cutting debris was finer, chip removal was smoother, and surface gloss significantly improved.<\/p>\n\n\n\n

Technical Explanation<\/h2>\n\n\n\n

Constant-Speed Endless Motion: \u2003<\/p>\n\n\n\n

The endless wire eliminates reversal cycles. Speed fluctuation remains under \u00b10.3%, avoiding transient acceleration stresses that cause microcracks in coatings.<\/p>\n\n\n\n

Stable Tension Control: <\/p>\n\n\n\n

Precision servo tension control keeps uniform stress distribution along the wire, minimizing local stress concentrations \u2014 ideal for thin-film-coated substrates.<\/p>\n\n\n\n

Cold Cutting Process: \u2003<\/p>\n\n\n\n

Liquid cooling efficiently removes heat; the thermal-affected zone is nearly zero. Coating temperature rise stays below 3\u00b0C, maintaining film stability.<\/p>\n\n\n\n

High-Precision Guide Wheel System: \u2003<\/p>\n\n\n\n

Wheel runout \u22641 \u03bcm ensures smooth motion and minimal surface scratching, reducing post-polishing volume by over 30%.<\/p>\n\n\n\n

Conclusion: A New Standard for Damage-Free Optical Cuttin<\/h2>\n\n\n\n

The test results confirm that Vimfun\u2019s Endless Diamond Wire achieves truly \u201czero coating damage\u201d in cutting 3D-coated optical lenses.<\/p>\n\n\n\n

Its constant-speed, constant-tension, and cold-cutting technology significantly enhance surface quality and process reliability \u2014 making it ideal for:<\/p>\n\n\n\n

AR\/VR lenses and head-mounted optics<\/p>\n\n\n\n

Automotive HUD optical modules<\/p>\n\n\n\n

High-precision optical filters and windows<\/p>\n\n\n\n

Multi-layer coated optical components<\/p>\n\n\n\n
