Fermat's WFT 13R table-type CNC horizontal boring mill is designed for rough machining and high-quality surface finishes. XYZ travels measure 177" × 98" × 59" (4,500 × 2,500 × 1,500 mm), and the machine also features a 27.5" (700-mm) V-axis ram travel, providing rigid spindle support while reaching to the center of the table. A 50-hp FANUC spindle motor powers the 5" spindle, with a two-speed gearbox for increased spindle speeds and maximum metal removal during heavy machining operations. All major components use stress-relieved castings, and all functional surfaces are hardened as one piece to 56 HRc. Further supporting rigidity and stable positioning are the oil-cooled pillow block bearing housings.
The machine uses a rotary table on a cross roller taper bearing, and the design includes two planetary gearboxes, two servomotors and two master/slave pinions for accurate positioning. This arrangement prevents backlash, limits static friction problems and enables continuous B-axis machining. The company's Speed Lock pallet exchange system suits high-volume production pieces without the need for full pallet shuttle systems, shortening time between setups.
Supporting automation such as robotic tool changers, the machine is also available with a selection of optional accessories, including facing heads as well as manual and automatic milling heads.
