How much does the Okuma MV-4000H cost?
Estimated price range
Our best estimate for a horizontal machining centers (hmc) in this class — not a quote from Okuma. Configuration moves it a long way.
Overview
The Okuma MV-4000H is listed as a horizontal machining center with a 400 x 400 mm pallet, travels of 560 / 560 / 640 mm in X, Y and Z and a 20 – 15,000 rpm spindle. The listed maximum workpiece is 630 x 900 mm (diameter x height) at up to 500 kg.
The spindle motor is listed as 18.5 / 22 kW (25 / 30 HP) and the taper as BT40 / HSK-A63. The interface has to be confirmed on any individual machine, because holders for the two are not interchangeable. The magazine holds 40 tools as standard with 80 listed as an option. Rapids are 60 / 60 / 60 m/min, chip-to-chip tool change is 3.0 sec and pallet change is 12 sec. Those three figures together describe a machine intended for short cycles on small parts, where non-cutting time is a large part of the total.
The pallet rotates in 0.001° indexing increments, which allows angled features and four-sided access without special fixtures. The control is listed as the Okuma OSP-P300S and machine weight as approx. 13,000 kg (28,660 lb). These are listed figures only. Check them against the nameplate and manual of the machine in question, particularly the taper and the control.
Okuma's MA-400HA has the same 400 x 400 mm pallet size and a 15,000 RPM spindle, but lists a 400 kg (882 lb) pallet load and a weight of approx. 16,000 kg (35,274 lb), against 500 kg and approx. 13,000 kg here.

Strengths & Limitations
Strengths
- 20 – 15,000 rpm spindle with a listed 18.5 / 22 kW (25 / 30 HP) motor
- Travels of 560 / 560 / 640 mm over a 400 x 400 mm pallet, with a listed workpiece limit of 630 x 900 mm
- Chip-to-chip tool change of 3.0 sec and pallet change of 12 sec keep non-cutting time low
- Rapid traverse of 60 / 60 / 60 m/min on X, Y and Z
- 0.001° pallet indexing for angled features and multi-face work
Limitations
- Taper is listed as BT40 / HSK-A63 without saying which a given machine has, so existing holders may not fit
- Workpiece weight is limited to 500 kg including fixtures
- The standard magazine is 40 tools; 80 is an option
- No torque figure is listed, so low-speed roughing capacity cannot be judged from the listed figures

Frequently Asked Questions
01
The listed travels are 560 / 560 / 640 mm in X, Y and Z over a 400 x 400 mm pallet. Maximum workpiece size is listed as 630 x 900 mm (diameter x height) and maximum workpiece weight as 500 kg.
02
The listing shows BT40 / HSK-A63 without stating which is fitted. The spindle speed is 20 – 15,000 rpm and the motor is listed as 18.5 / 22 kW (25 / 30 HP). Confirm the taper on the actual machine before buying holders.
03
Chip-to-chip tool change is listed at 3.0 sec and pallet change at 12 sec. Rapid traverse is 60 / 60 / 60 m/min in X, Y and Z. The magazine holds 40 tools as standard, with 80 as the listed option.
04
The control is listed as the Okuma OSP-P300S. Machine weight is approx. 13,000 kg (28,660 lb), which matters for rigging and for the floor it stands on. Both should be confirmed from the machine's own documentation.
