UPC TM Cutting Edge for Infrared (IR) Lenses and Cemented Carbide Moulds
UPC TM -R exhibits outstanding performance in ultra-precision spherical and aspherical cutting
1 to 3 μm
Negative Rake Face
■ Features 1. Achieves cutting edge arc waviness of 50 nm (0.05 μm) over a wide working angle range of 90°. 2. The cutting edge is uniformly finished in high quality, achieving a surface roughness in the order of nanometres. 3. A record of the cutting edge arc waviness measured with our uniquely developed measuring instrument (with a resolution of 5 nm) is attached to the product for thorough quality control. ■ Applications 1. Camera lens moulds for CD, DVD, and BD players 2. Lens moulds for digital cameras 3. Camera lens moulds for smartphones, PCs, and tablets 4. Infrared lens 5. Spherical and aspherical mirrors for lasers and X-rays 6. Various spherical and aspherical lenses 7. Profile processing using an ultra-precision processing machine
