  • Overview +

    Whether you need to manufacture a freeform part today or want the flexibility for future market requirements, the Freeform® TL 1000 is precisely the machine you need.

    Precitech has added our 500 mm X axis to the field proven Freeform TL platform, increasing flexibility and precision. The result is the largest commercially available ultra precision freeform machining system - the Freeform TL 1000.

    Customers can diamond turn, micro-mill, micro-grind, and groove non-rotationally symmetric surfaces on a one-meter platform.

    • Industry leading swing and load capacity
    • Flexibility to produce freeform geometries with 3 linear and 2 rotary CNC axes
    • 5 Axis freedom with 3 axis performance Y axis and spindle designed for maximum thermal stability
    • Thermally controlled enclosure options insure accuracy during long cutting-time parts
    • Reduced sensitivity to vibration enabled by its integral TMC MaxDamp® isolation system
