How much does the Okuma V100R cost?
Estimated price range
Our best estimate for a cnc lathes / turning center in this class — not a quote from Okuma. Configuration moves it a long way.
Overview
The Okuma V100R is a heavy chucking lathe: 1,000 mm (39.4 in) maximum turning diameter, 1,250 mm (49.21 in) swing, and a rated workpiece weight of 1,000 kg (2,205 lb). The weight figure deserves attention. A solid steel disc at full diameter reaches that weight at a modest thickness, so for dense parts the weight limit, not the 890 mm (35.0 in) turning length, sets the size of the job.
The spindle is rated 45/37 kW (60/50 hp) and runs 13 to 1,250 rpm. The V920EX has the same 1,250 rpm top speed but lists 30/22 kW, so the V100R brings 50% more power on the first figure of the pair. Its range also starts lower, at 13 rpm against 20 rpm on the V920EX, which helps hold a sensible surface speed near full diameter.
The largest listed chuck is 610 mm (24 in), hydraulic. That is well inside the 1,000 mm turning diameter, so plan the workholding for parts near full diameter with Okuma. Rapid traverse is 24 m/min (78.74 fpm).

Strengths & Limitations
Strengths
- Rated for workpieces up to 1,000 kg (2,205 lb)
- 45/37 kW (60/50 hp) spindle, against 30/22 kW on the V920EX
- 1,000 mm (39.4 in) turning diameter inside a 1,250 mm (49.21 in) swing, which leaves room for fixtures
- Speed range reaches down to 13 rpm for large-diameter cuts and up to 1,250 rpm
Limitations
- Largest listed chuck is 610 mm (24 in), well under the 1,000 mm (39.4 in) turning diameter
- Top speed is 1,250 rpm; the V760EX runs to 2,000 rpm for smaller parts
- Workpiece weight is capped at 1,000 kg (2,205 lb), which dense parts reach before they fill the envelope
- Turning length is 890 mm (35.0 in), only a little more than the 860 mm (33.86 in) of the V920EX

Frequently Asked Questions
01
Okuma lists a maximum workpiece weight of 1,000 kg (2,205 lb). A dense part can reach that limit well before it reaches the 1,000 mm (39.4 in) turning diameter or the 890 mm (35.0 in) turning length. Ask Okuma whether the figure includes the chuck jaws and fixture.
02
The table lists hydraulic chucks up to 610 mm (24 in). Maximum swing is 1,250 mm (49.21 in) and maximum turning diameter 1,000 mm (39.4 in), so there is clearance around the largest chuck for fixtures that reach beyond it.
03
Power and capacity. The V100R has a 45/37 kW (60/50 hp) spindle where the V920EX lists 30/22 kW (40/30 hp). Turning diameter is 1,000 mm (39.4 in) against 920 mm (36.22 in) on the V920EX, and swing is 1,250 mm (49.21 in) against 1,000 mm (39.37 in) on the V920EX. Both top out at 1,250 rpm and rapid at 24 m/min (78.74 fpm).
