Mono-crystal diamond cutting tool for roll molds Realization of high-precision micro-groove forming with roll molds for optical films [Issue] Video devices such as TVs and displays are becoming higher resolution types, such as "4K8K", and having smaller and more complex structures such as xR (VR/AR/MR, etc.) goggles. In order to achieve these technologies, finer machining of precision molds for optical films and optical elements is required. [Solution] The use of fine cutting tools with mono-crystal diamond enables highprecision fine groove forming with continuous pitch in the machining of roll molds for optical films. Mono-crystal diamond has excellent wear resistance and contributes to the long-time continuous machining of large rolls. Example of mono-crystal diamond ultrafine cutting tool edge shape Reference example of nano radius ultrafine cutting tool (radius size under R1μm) Expected effects for optical parts mold are contributing smoother release ability, improvement of surface texture, and suppression of rainbow reflection. Supposed production range: R100nm ～ under R800nm Mono-crystal diamond ultrafine cutting tool Standard Specification [Nose angle under 15°] [Size: mm] * The specification is shown for reference only.
