    Accessories / Special Features
    * SIEMENS CNC Control, Model SINUMERIK 3 G for infeed of grinding head (Z),
    table adjustment (X), dressing amount and speed (W, V) with all the
    necessary cycles and programming possibilities. Manual Control unit for
    correction of cutting parameters
    * CNC controlled automatic grinding process with input of feed amounts for
    pre-grinding, fine grinding,finish grinding, spark-out and lift-off from
    * CNC controlled swivelling grinding wheel dressing device, built on below
    the segmental head with automatic compensation. Dressing can be done
    during the grinding process, i.e. the grinding head and rotary table stay
    in place.
    * Automatic Swivelling of grinding head from cross grinding to radial
    * Radial grinding = higher material removal. Cross grinding = more accurate
    and flatness
    * Rotary magnetic chuck with ring pole division and stepless adjustment of
    magnetic power.
    * Adjustable gap control (to avoid air grinding),
    * Separate switch and control cabinet with Amperemeter for Grinding Power
    * Large Coolant device with 2 Magnetic Separators and large intermediate
    tank for approx.
    * 3000 Ltrs. Coolant Liquid, Coolant Supply thru grinding spindle center,
    Oil mist exhaust,

    Condition : Good to very good. Machine can not be demonstrated under power
    because of high Power rate.
