Mazak FJV BT50 vs Mazak FJW-100/160
Yamazaki Mazak vs Yamazaki Mazak · Vertical Machining Centers
Summary
The Mazak FJV BT50 and the Mazak FJW-100/160 are both 50-taper vertical machining centers for large parts, but they are in different size classes and serve different jobs. The FJV BT50 series covers 59.06 in (1,500 mm) to 165.35 in (4,200 mm) of X with a 10,000 rpm spindle. The FJW-100/160 has 167.32 in (4,250 mm) of X, 125.98 in (3,200 mm) of Y and a W-axis cross rail for tall workpieces.
The FJW-100/160 is larger on every travel and load row: 31.5 in (800 mm) of Z against 25.98 in (660 mm), and 48,501 lb (22,000 kg) of table load against 5,512 lb (2,500 kg) to 22,046 lb (10,000 kg). It delivers 470 ft-lb (637 Nm) continuous against 176 ft-lb (239 Nm). The FJV BT50 runs faster with more power, 10,000 rpm and 30 kW (40 HP) against 6,000 rpm and 22 kW (30 HP). Tool capacity and rapid traverse overlap, 30 tools to 60 tools against 50 tools, so those rows have no winner.
