Fast Tool Servo

  • Overview +


    The Fast Tool Servo systems enable the diamond turning of surface structures such as micro prisms, lens arrays, torics and off-axis aspheres with departures up to 1000 microns.

    The FastCom FTS controller provides tool position commands for the Fast Tool Servo at update rates up to 25kHz. Position commands (including tool compensation) are calculated in real time, without interpolation, utilizing inputs from the existing encoders on the machines axes.
