How much does the Okuma MB-8000H 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 MB-8000H is a No. 50 taper horizontal machining center with an 800 x 800 mm (31.5 x 31.5 in) pallet. The listed figures put the maximum workpiece at ø1,200 x 1,200 mm (ø47.2 x 47.2 in) and the pallet load at 2,500 kg (5,512 lb), which places it in the class used for gearbox housings, pump bodies and medium castings.
The spindle is listed at 6,000 RPM as standard with 10,000 and 12,000 RPM as options, driven by a 30/22 kW motor (10 min/continuous). At 6,000 RPM the machine is set up for iron and steel with large cutters; the faster options matter if aluminium parts or small tools are part of the mix. The magazine holds 60 tools as standard. Guideways are listed as box ways on all axes, a construction chosen for damping and heavy cuts over outright axis speed, and a dual pallet changer is listed as standard so one pallet can be loaded while the other is in the cut.
The control is the Okuma OSP-P500M. The Thermo-Friendly Concept, the anti-crash system and Servo Navi are all listed as standard. No axis travels or rapid traverse rates appear among the listed figures. Treat everything here as listed figures and confirm them against the documentation of the machine being offered. Among Okuma's horizontals the MB-10000H is the step up, with a 1,000 × 1,000 mm (39.37 × 39.37 in) pallet and 40 tools as standard.

Strengths & Limitations
Strengths
- Pallet load listed at 2,500 kg (5,512 lb) on an 800 x 800 mm (31.5 x 31.5 in) pallet
- Maximum workpiece of ø1,200 x 1,200 mm (ø47.2 x 47.2 in) leaves room for tall fixtures and large housings
- No. 50 taper spindle with a 30/22 kW motor (10 min/continuous) for heavy milling and boring
- Dual pallet changer is listed as standard, so loading happens outside the cut
- Thermo-Friendly Concept, anti-crash system and Servo Navi are listed as standard with the OSP-P500M control
Limitations
- The standard spindle tops out at 6,000 RPM; 10,000 and 12,000 RPM are listed as options
- No axis travels or rapid traverse rates are among the listed figures, so reach and cycle-time estimates need Okuma's data
- Only the standard 60-tool magazine is listed, with no larger capacity shown
- Box ways on all axes are a choice for stiffness, and the listing gives no rapid rate to show what that costs in positioning speed

Frequently Asked Questions
01
The listed maximum workpiece is ø1,200 x 1,200 mm (ø47.2 x 47.2 in) and the pallet load is 2,500 kg (5,512 lb) on an 800 x 800 mm (31.5 x 31.5 in) pallet. The load has to cover fixture and part together, so weigh the tombstone before planning a heavy casting.
02
A No. 50 taper spindle at 6,000 RPM as standard, with 10,000 and 12,000 RPM listed as options. The motor figure is 30/22 kW at the 10 min and continuous ratings. No torque figure is listed, so heavy-cut capacity at low speed should be confirmed with Okuma.
03
The control is the Okuma OSP-P500M. The Thermo-Friendly Concept, the anti-crash system and Servo Navi are each listed as standard, along with a dual pallet changer and box ways on all axes. The magazine is listed at 60 tools as standard.
04
The MB-10000H is the larger machine, with a 1,000 × 1,000 mm (39.37 × 39.37 in) pallet against 800 x 800 mm here. Both are No. 50 taper and both list a 30/22 kW motor as standard. The MB-10000H lists 40 tools as standard where the MB-8000H lists 60, and its rapid traverse is 50 m/min (1,969 ipm).
