Optical Sheet Molds / Ultra-Precision Cutting Tool UPC-Nano groove
LCD Light Guide Plate Molds / Ultra-Precision Cutting Tool UPC-Nano endmill
・A grooving tool with a minimum groove width of 5 µm. ・High-precision-polished durable cutting edge. ・Enables high-precision fine grooving that cannot be achieved using the photolithography or ion-beam method. ■Features A grooving tool with a minimum groove width of 5 µm. Grooves of high aspect ratio not achievable by the photolithography and ion beam methods can be produced within a short period of time. The cutting edge that is very precise and durable makes this tool ideal for linear ultra fine grooving of holographic gratings and ultra fine & clear grooving of LCD light guide plates. Enables High-Precision Linear Grooving with the World's Smallest Blade Width
・Enables machining with a high aspect ratio of 2.5 times the rotation diameter. ・High-precision-polished durable cutting edge. ・Enables high-precision fine grooving that cannot be achieved using the photolithography or ion-beam method. ■Features ・LCD light guide plate molds, Hologram grating, Fine free curve grooving ■Applications Free Curve Ultra Fine Grooving of World's Smallest Class Possible This endmill is capable of machining rectangular grooves with free curves. High aspect ratio grooves that cannot be obtained by the photolithography or ion beam methods can be machined in a short time into an edgy shape.
・Fine linear grooving, Optical sheet molds, Light guide plate molds ■Applications
