    If you are looking to manufacture Head-up Display molds for automotive or aerospace applications, the Nanoform® 700 ultra or Nanoform® L 1000, are uniquely positioned to meet your needs. 

    When equipped with an HD-160 spindle with a C axis and Adaptive Control Technology (ACT) there is no better solution in the market today for this application.

    The stiftness and dampening of the HD-160 results in improved surface finish and the capacity for large parts and fixtures. The HD-160 has an ultimate load capacity of 170 Kg (375 lbs.) 

    Precitech's C axis and high resolution encoder, with feedback resolution of 0.010 arc-sec, and servo tuning algorithims allow for tight control of the rotary position of the spindle. The result is the capability to manufacture high accuracy freeform shapes with superior surface finish using XZC machining. 

    Finally, Adaptive Control Technology (ACT), exclusively offered by Precitech, utilizes a unique learning algorithum to eliminate errors in X and Z that repeat with spindle position. This allows you to increase the spindle speed, reducing manufacturing time while improving form error.
