Product Details
The FPK series is a modern interpretation of the classic universal tool milling machine. The console-type machine stand is made of high-quality grey cast iron for precision and durability. Operating elements are concentrated on the right-hand side for operator control. Box guides provide large contact surfaces for dimensional stability and load-bearing capacity. The main spindle gearbox is integrated in the upper beam for efficient power transmission and low vibration. The robust 2-stage gearbox with hardened and ground gears offers a wide, infinitely variable speed range. The vertical milling head can be swiveled on both sides; the quill is manually movable and the vertical head can be removed to access the horizontal spindle holder. A counter-holder is standard for long milling arbours.

Feed technology
Powerful servomotors enable infinitely variable feed speeds and rapid traverse in all axes. Preloaded ball screws in all axes guarantee precise, smooth and low-wear positioning without backlash and a long service life.

Equipment
Standard equipment includes a powerful coolant system, LED work lighting and a comprehensive tool package with long arbours and collets. Integrated electronic functions provide positioning control, electronic spindle load indicator, electronic handwheels, joystick axis movement, and the X.pos 3.2 position indicator.
