Nanoform L 1000 ultra grind

Nanoform L 1000 ultra grind ultra precision lathe for diamond turning and grinding
  • Overview +


    The Nanoform L1000 ultra grind is designed for the ultimate productivity and flexibility in diamond turning and deterministic microgrinding of optical lenses, mold inserts, mirrors, and precision mechanical components. It can be configured with up to 5 axes (X, Z, C, B, and WFast Tool Servo).

    Common applications include aspheric and freeform shaped glasses, ceramics, and steels. It’s is also very beneficial for turning infrared materials that require water-based coolant, such as silicon.

    Nanoform L 1000 machines have the largest swing capacity of any standard production ultra precision machining systems available on the market.

    Benefits
    • Expand your capabilities with full flood coolant compatibility in a large frame machine
    • Maximize flexibility with diamond turning and ultra precision grinding capabilities in a single machining system
    • Assure your part quality with performance rivaling that of small frame machines

    Capabilities
    • Single point diamond turning (2 or 3 axes) including non-axi-symmerical designs of optics and optical molds
    • Tool normal diamond turning (3 or 4 axes) utilizing a contouring B axis for freeform shapes in hard-to-machine materials, such as silicon
    • Precision grinding and milling (2 or 3 axes) utilizing a 15,000 RPM spindle in a 45° or 90° orientation for cross-axis grinding of precision glass optics
    • Freeform grinding and milling (3 or 4 axes) utilizing a 80,000 RPM spindle and a rotary B axis for parallel grinding or 45° grinding of optical mold inserts such as tungsten carbide for glass pressing applications
