Machine Comparison
Mazak FJV 5-Face vs Okuma GENOS M460-VE
Yamazaki Mazak vs Okuma · Vertical Machining Centers
Summary
The Mazak FJV 5-Face is a series of large vertical machining centers that machine the top and four sides of a workpiece in one clamping, while the Okuma GENOS M460-VE is a compact vertical machining center for small-tool work. They serve different jobs, and the Mazak figures for tools and rapid traverse are series ranges rather than one machine's values.
The Mazak has the heavier spindle: 30 kW (40 HP) continuous on a CAT No.50 taper, against 22/18.5 kW (30/25 hp) on BT40. The Okuma is faster at 15,000 rpm against 10,000 rpm. Tool capacity runs from 30 tools to 60 tools across the Mazak series against 32 on the Okuma, and Mazak rapid traverse ranges from 886 ipm (23 m/min) to 1,575 ipm (40 m/min), where the Okuma lists 40 m/min in X and Y and 32 m/min in Z.

Advantages
Mazak FJV 5-Face
- 30 kW (40 HP) continuous spindle power against 22/18.5 kW (30/25 hp)
- CAT No.50 spindle taper for cast iron and steel work, against BT40
- Machines the top and four sides of a large part in one clamping
Okuma GENOS M460-VE
- 15,000 rpm spindle against 10,000 rpm
- BT40 spindle suited to aluminum and small-tool work
- Compact machine for vise and fixture-plate work rather than large plates and frames
Verdict
These machines do not compete for the same parts. Choose the Mazak FJV 5-Face for large plates, bases and frames in cast iron and steel that need five-face machining in one clamping, backed by 30 kW (40 HP) continuous on a 50-taper spindle. Choose the Okuma GENOS M460-VE for aluminum and small-tool work on vise-sized parts, where 15,000 rpm on a BT40 spindle and 32 tools are the useful figures.
