Overview
The Mazak FJV BT50 page covers the eight double-column vertical machining centers Mazak lists as the FJV (CAT No.50) series, from the FJV-35/60 up to the FJV-100/160. One spindle serves the whole series: CAT No.50, 10,000 rpm, 30 kW (40 HP) continuous and 176 ft-lb (239 Nm) continuous. What changes from model to model is the size of the envelope and the load the table carries.
The three smallest sizes show how the series steps. The FJV-35/60 has 59.06 in (1,500 mm) of X and 31.5 in (800 mm) of Y, a 68.5 in (1,740 mm) × 29.53 in (750 mm) table and a 5,512 lb (2,500 kg) table load. The FJV-35/80 keeps that Y and stretches X to 78.74 in (2,000 mm), with 6,614 lb (3,000 kg) on the table. The FJV-60/80 keeps the X of the FJV-35/80 and widens Y to 55.12 in (1,400 mm), which raises the load to 8,818 lb (4,000 kg) and the machine weight from 42,110 lb (19,101 kg) to 57,320 lb (26,000 kg). The remaining models, FJV-35/120, FJV-60/120, FJV-60/160, FJV-100/120 and FJV-100/160, carry the series on to 165.35 in (4,200 mm) of X, 96.46 in (2,450 mm) of Y and 22,046 lb (10,000 kg).
Height does not scale. Z travel is 25.98 in (660 mm) on every model, with rapids of 1,575 ipm (40 m/min) in Y and 1,181 ipm (30 m/min) in Z. X rapid is 1,575 ipm (40 m/min) on the FJV-35/60, FJV-35/80 and FJV-60/80, and the series minimum is 866 ipm (22 m/min).
At 40% ED the spindle gives 37 kW (50 HP) and 258 ft-lb (350 Nm). It is a gearless integral spindle and motor in a symmetrical, temperature-controlled unit. A 7,000 rpm high-torque spindle and a BT40 18,000 rpm high-speed spindle are options. So are three additions that change what the machine does: a multi-surface machining attachment for four-face work with one angle tool, an additional axis commanded as a 4th axis, and a 2-pallet changer. The control is the MAZATROL SmoothG.

Frequently Asked Questions
01
Mazak lists eight under FJV (CAT No.50): FJV-35/60, FJV-35/80, FJV-35/120, FJV-60/80, FJV-60/120, FJV-60/160, FJV-100/120 and FJV-100/160. Across them the distance between columns runs from 33.9 in (861 mm) to 98.43 in (2,500 mm), machine height from 137.8 in (3,500 mm) to 141.73 in (3,600 mm) and machine weight from 38,800 lb (17,599 kg) to 101,190 lb (45,899 kg).
02
The FJV-35/60 has 59.06 in (1,500 mm) of X and 31.5 in (800 mm) of Y with a 5,512 lb (2,500 kg) table load and weighs 38,800 lb (17,599 kg). The FJV-35/80 lengthens X to 78.74 in (2,000 mm) on the same Y, with a 6,614 lb (3,000 kg) load. The FJV-60/80 has the X of the FJV-35/80 with 55.12 in (1,400 mm) of Y and an 8,818 lb (4,000 kg) load on an 88.19 in (2,240 mm) × 49.21 in (1,250 mm) table. All three, FJV-35/60, FJV-35/80 and FJV-60/80, share 25.98 in (660 mm) of Z, the same spindle and 30 tools.
03
The standard spindle runs to 10,000 rpm on a CAT No.50 taper and is meant for cast iron, steel and nonferrous metal. It is rated 30 kW (40 HP) continuous and 176 ft-lb (239 Nm) continuous, or 37 kW (50 HP) and 258 ft-lb (350 Nm) at 40% ED. A 7,000 rpm high-torque spindle for rough machining of steel and cast iron is optional, as is a BT40 high-speed spindle at 18,000 rpm.
04
Yes, as an option. Mazak offers a multi-surface machining attachment that enables four face machining with one angle tool, and an additional axis that is commanded as a 4th axis from the machining program. Buyers who want side-face capability as standard equipment should look at the FJV 5-Face series, which has the same 25.98 in (660 mm) of Z and machine weights of 41,226 lb (18,700 kg) to 103,616 lb (46,999 kg).
05
Tool capacity is 30 tools to 60 tools depending on the model. A tool can be up to Ø4.92 in (125 mm) in diameter with neighbouring pockets filled and Ø8.27 in (210 mm) with them empty, up to 14.96 in (380 mm) long and up to 44 lb (20 kg). Mazak notes that the compact spindle cartridge reduces interference, which allows shorter tools to be used.
