Freeform X small axis diamond turning machine for advanced optics
  • Overview +


    New Freeform X


    Based on two successful and proven products, Precitech’s Freeform L and Nanoform X, the Freeform X addresses the needs of some of today’s most demanding diamond turning applications including:


    • High quality infrared optics for defense, security, and EUV beam-directing optics
    • Consumer products such as the complex optics integrated into new generation reality-based headwear and mobile devices
    • Lighting and heads-up displays (HUD) for the automotive sector.

    The new Freeform X has unique capabilities that allow it to support the advanced needs of emerging applications with:

    • Five operational axes facilitate a high-level of machining flexibility with 200 millimeters of X and Z-axis travel and 100 millimeters of translation in the Y direction
    • The smaller structural loop of the Freeform X provides excellent stiffness and stability enabling the manufacturing of optics with exceptional surface form and finish
    • The Freeform X occupies less than 2 square meters providing customers with a powerful machine in a compact footprint minimizing the necessity for valuable production floor space
    • When integrated with Precitech’s proprietary Fast Tool Servo, the FTS5000, and feature rich FastCAM software, the system provides additional capability for increasing productivity with up to 15x faster processing times for the manufacture of standard and complex shapes with excellent surface quality – form, finish and waviness
