CNC Machine


Edmund Optics® utilizes a wide range of CNC machining equipment including ultrasonic machining and high speed cutting (HSC) technology from DMG MORI® for the machining of freeform optics and complex optical component geometries. CNC machines offer the highest amount of precision and flexibility when it comes to fabricating components beyond basic shapes. Our true 5-axis precision machine centers have the capability to machine lightweight structures and high aspect ratio components with specialty bevels, precision holes and inserts, and mounting interfaces. In addition to optical glass, we can machine a wide range of demanding materials including ceramics, corundum, tungsten carbide, and even composites. Some high-tech materials, such as Tungsten Carbide and composites, cannot be machined using conventional machining and can only be shaped using ultrasonic machining.


DMG MORI® ULTRASONIC 5-Axis Precision Machine Centers greatly reduce tool wear compared to other optics manufacturing equipment, which decreases cycle times and makes tighter tolerances achievable. They are ideal for optical components with high aspect ratios and complex geometries, such as inflected aspheres and freeforms, along with parts with bevels, holes, channels, and other features. The Precision Machine Centers can manufacture tooling for glass molding and other processes more quickly than traditional diamond turning techniques, therefore reducing lead times.
