Mazak FJV 5-Face vs Mazak VTC-Ez
Yamazaki Mazak vs Yamazaki Mazak · Vertical Machining Centers
Summary
The Mazak FJV 5-Face and the Mazak VTC-Ez are both vertical machining centers for long work, built in different ways. The FJV 5-Face is a 50-taper machine for large plates, bases and frames machined on the top and four sides in one clamping. The VTC-Ez is a long-table machine for rails, extrusions and frames, with two zones so one setup loads while the other cuts.
The FJV 5-Face series covers 59.06 in (1,500 mm) to 165.35 in (4,200 mm) of X, a span that includes the VTC-Ez's 67.32 in (1,710 mm) to 69.29 in (1,760 mm). It is deeper in Y, 31.5 in (800 mm) to 96.46 in (2,450 mm) against 25 in (635 mm) to 30 in (762 mm), and has 30 kW (40 HP) and 176 ft-lb (239 Nm) continuous against at most 18.5 kW (25 HP) and 87 ft-lb (118 Nm). The VTC-Ez offers spindles from 6,000 rpm to 15,000 rpm and CAT No. 40 as well as CAT No. 50.
