Design
Ball screws in all axes
Linear guides and guide carriages from Bosch Rexroth (25 mm)
Driven nut in the X and Y axis from Bosch Rexroth
2 ball screws in the Y axis (gantry design) – two motors move the gantry on both sides
Concealed, protected guides shield sensitive components from contamination (C-design)
Large, stable Z axis, suitable for HF spindles up to 4.5 kW ER32 or tool-change HF spindles up to 3.6 kW SK30
Steel beam 200 x 100 mm in the X axis with reinforced side panels for greater stability
Reinforced base frame from the PFH series – set up even more stably
Frame construction in ergonomic design, operator-friendly thanks to inward-positioned feet
Travels up to approx. 2500 x 2000 mm
Developed specifically for the PFU gantry risers Z-300 and Z-450 – even more travel in the Z axis
Control & drive
Available with closed-loop or servo motors
Control cabinet with servo motor 750 W or closed loop 6 Amp. (optional)
Automatic tool changer optional (10-position magazine protected in the housing / 8-position disc changer)

What is the BZT PFU-S-2 series?
Developed for gantry risers Z‑300 and Z‑450 – more working range, more Z stroke, robust industrial design. The newly developed PFU-S-2 series was developed specifically for the PFU gantry risers Z-300 and Z-450. Thanks to the optional gantry risers, this series stands out with large travels in the Z axis: the working range becomes larger, larger materials can be machined in more complex ways. So that flawless results are possible in these dimensions, the gantry milling machine was designed more robustly. Reinforced side panels of the gantry risers and a steel beam in the X axis reduce vibrations during machining. Compared to PFU and PFU-S, the base frame is set up even more stably; larger side panels in a stable C-section steel construction protect the guides.
