Fermat Group's CNC horizontal boring mill WFT 13 is designed for a variety of machining operations being performed on large parts within the defence, energy, oil and various other industries.

The WFT 13 features stress relieved castings for all major components and all functional surfaces are hardened as one piece to 56 HRC. The WFT 13 is equipped with direct drive motors for movements along the axes with German planetary gearboxes, and oil cooled pillow block bearing housings for more accurate and stable positioning.

The standard WFT 13 model is equipped with a rotary table on a cross roller taper bearing produced by a certified European manufacturer. The table is equipped with two servomotors, two planetary gearboxes and two pinions in a master-slave relationship for accurate positioning, zero backlash, no slip stick and continuous B-axis machining as a standard feature.

The WFT 13 model is offered with a new 4 m x 1.6 m / 157" x 63" plain table design. X-axis travel is 4 m / 157". This design was created due to the demand of customers with specific machining needs. Customers with longer parts that utilize cross milling processes needed more support from their tables, and Fermat Group designed a table that could meet these needs with this 15-tonne design.

The WFT 13 can be equipped with a 40 or 60 station automatic tool changer, or with an optional 105 station robotic tool changer. "The powerful headstock and spindle motor (37 kW / 50 HP) of the WFT 13 is designed for rough machining with an emphasis on high quality machining surface finishes," said a company spokesperson. "A two speed gear box for spindle speeds is provided, allowing for maximum metal removal during heavy machining operations."

Precision linear scales are installed on all three linear axes to help provide accuracy and repeatability of movement. A selection of optional accessories such as a through the spindle coolant system, manual and automatic milling heads, and pallet shuttle systems are available for the WFT 13 to help improve efficiency or streamline machining processes.
