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-5000HII is a horizontal machining center with a 500 × 500 mm (19.69 × 19.69 in) pallet and travels of 760 mm (29.9 in) in X, 760 mm (29.9 in) in Y and 810 mm (31.9 in) in Z. The spindle runs 50–15,000 rpm on a 26 kW motor, and the axes rapid at 60 m/min (2,362 ipm).

Okuma states the maximum machining volume as 760 × 760 × 810 mm (29.92 × 29.92 × 31.89 in), identical to the travels, so nothing is lost at the ends of the strokes. X and Y are equal, which gives a square working window, and a tombstone or part wider than the 500 mm pallet can still be reached from edge to edge.

Maximum work weight is 500 kg (1,100 lb). That figure has to cover the fixture as well as the parts, and on a 500 mm pallet a steel tombstone takes a large share of it, so the MB-5000HII fits aluminium and lighter iron parts better than dense, heavy workpieces. The 15,000 rpm spindle points the same way. One spindle range and one motor rating are listed, with no bracketed options, and the table gives no taper or torque.

The magazine holds 48 tools and the control is the Okuma OSP-P500M. Within the series the MB-4000H is the smaller choice, with a 400 × 400 mm (15.75 × 15.75 in) pallet and the same 50–15,000 rpm standard range, while the MB-10000H jumps to a 1,000 × 1,000 mm (39.37 × 39.37 in) pallet and a No. 50 taper.

Strengths & Limitations

Strengths

Travels of 760 × 760 × 810 mm are fully usable: the listed machining volume is 760 × 760 × 810 mm (29.92 × 29.92 × 31.89 in)
50–15,000 rpm spindle with a 26 kW motor for aluminium and small-tool work
60 m/min (2,362 ipm) rapid traverse on X, Y and Z
48-tool magazine and the Okuma OSP-P500M control are in the listed specification
Larger envelope than the MB-4000H, which lists 560 × 560 × 625 mm on a 400 × 400 mm pallet

Limitations

Maximum work weight of 500 kg (1,100 lb) includes the fixture, which limits heavy steel or iron parts on a tombstone
Only one spindle range, one motor rating and one magazine size are listed, so there is no stated higher-torque or larger-magazine choice
No spindle taper or torque figure is listed, so toolholder compatibility and roughing capacity must be confirmed
48 tools can run short when several part numbers share the machine

Best For

Aluminium housings and manifolds within 760 × 760 × 810 mm Tombstone production on a 500 × 500 mm pallet Small-tool work that needs up to 15,000 rpm Parts and fixtures totalling no more than 500 kg (1,100 lb)

Frequently Asked Questions

01 What are the travels of the Okuma MB-5000HII?

760 mm (29.9 in) in X, 760 mm (29.9 in) in Y and 810 mm (31.9 in) in Z. Okuma lists the maximum machining volume as 760 × 760 × 810 mm (29.92 × 29.92 × 31.89 in), so the whole travel is usable. Rapid traverse is 60 m/min (2,362 ipm) on all three axes.

02 How much weight can the MB-5000HII pallet carry?

The maximum work weight is 500 kg (1,100 lb) on a 500 × 500 mm (19.69 × 19.69 in) pallet. Count the tombstone or fixture plate, the clamps and every part loaded at once against that figure, not just a single workpiece.

03 What spindle and tool magazine does it have?

The spindle runs 50–15,000 rpm and the motor is listed at 26 kW. The magazine holds 48 tools. Okuma's table for this model shows no optional ranges or magazine sizes and no taper, so ask which toolholder interface the machine is built with.

04 Which control does the MB-5000HII use?

The table lists the Okuma OSP-P500M, Okuma's own control. No control options or software packages are named in the listed rows, so anything beyond the base control should be confirmed on the quotation.

05 How does the MB-5000HII compare with the MB-4000H?

The MB-4000H has a 400 × 400 mm (15.75 × 15.75 in) pallet and a machining volume of 560 × 560 × 625 mm (22.05 × 22.05 × 24.61 in). The MB-5000HII has a 500 × 500 mm pallet and 760 × 760 × 810 mm. Both run 50–15,000 rpm as standard and rapid at 2,362 ipm; the MB-4000H also lists a 50–20,000 rpm option and a No. 40 (BT40) spindle.
