Hyundai-WIA’s F750M and F960M large-capacity CNC vertical machining centers are designed for industrial mold and die applications in small- to medium-sized job shops. X-, Y- and Z-axis travels measure 61" × 29.5" × 28.5", respectively, on the F750M, and 96.5" × 37.4" × 33.5", respectively, on the F960M.
Both machines feature a 12,000-rpm, built-in, cartridge-type spindle. Precise angular bearings provide high speed acceleration and deceleration for smooth machining at high rpms, the company says. The main spindle delivers minimal noise and vibration even at high cutting speeds for stable machining and minimal thermal transmission, the company says. The standard Big Plus spindle system provides dual contact between the spindle face and the flange face of the toolholder. The 16 to 25 hp spindle motor is rated at 893/732 Nm torque. Through-spindle coolant is standard. The VMCs are equipped with 20-tool, side-mount, swing-arm-type toolchangers, with a 40-tool option for the F750M. The toolchanger and magazine are separated by a shutter system that closes during machining to keep out chips and fluids. Maximum tool diameter is 125 mm OD, with a maximum tool length of 300 mm and weight of 20 kg.
Mold Package II CNC mold software is included in the controls. The package includes a FANUC 31iA control, AICC II package, AI contour control II, smooth backlash compensation, thermal displacement feature and automatic power-off feature.
