How much does the Okuma MA-12500H 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 MA-12500H is a No. 50 taper horizontal machining center built around a 1,250 × 1,250 mm (49.21 × 49.21 in) rotary pallet. Its standard spindle is rated 45/37 kW (60/49 hp) with a 50–6,000 rpm range, rapid traverse is 42 m/min (1,654 ipm), and the magazine holds 81 tools.
Size shows in two comparisons. The MA-8000H, on an 800 × 800 mm (31.50 × 31.50 in) pallet, starts at 30/22 kW (40/30 hp) and lists 45/37 kW only as an option, so the bigger motor is the baseline here. And where the MA-8000H and the MB-10000H both rapid at 50 m/min (1,969 ipm), the MA-12500H is listed at 42 m/min (1,654 ipm), the trade for moving larger axes and heavier work.
Okuma lists two alternative spindles in brackets: a 10–4,500 rpm range and a 50–12,000 rpm range, with power ratings of 40/37/30 kW (15 min/30 min/cont) and 37/26 kW (10 min/cont). The table does not say which rating goes with which speed range, so have the quotation state the pairing. Magazine options are 129 and 177 tools.
The machining volume row gives two dimensions, 2,200 × 1,650 mm (86.61 × 64.96 in), without naming the axes, and there is no pallet load figure. Both need confirming before fixtures are designed for a machine of this size.

Strengths & Limitations
Strengths
- 1,250 × 1,250 mm (49.21 × 49.21 in) rotary pallet with a No. 50 taper spindle
- 45/37 kW (60/49 hp) as the standard spindle rating; on the MA-8000H 45/37 kW is an option
- 81-tool magazine as standard, with 129 and 177 tools as options
Limitations
- Rapid traverse is 42 m/min (1,654 ipm), slower than the 50 m/min (1,969 ipm) of the MA-8000H and MB-10000H
- The 10–4,500 rpm and 50–12,000 rpm spindles are options; the standard range is 50–6,000 rpm
- Okuma's table gives no pallet load, and the machining volume row shows only two dimensions

Frequently Asked Questions
01
The standard spindle is No. 50 taper, 45/37 kW (60/49 hp), with a 50–6,000 rpm range. In brackets Okuma lists a 10–4,500 rpm range and a 50–12,000 rpm range, and power ratings of 40/37/30 kW (15 min/30 min/cont) and 37/26 kW (10 min/cont). The table does not pair them, so confirm the combination in the quotation.
02
81 tools as standard. Magazines of 129 and 177 tools are listed as options. On a pallet of this size, parts tend to have many features per setup, so count the tools for the longest job before choosing.
03
The MA-8000H has an 800 × 800 mm (31.50 × 31.50 in) pallet, a standard 30/22 kW (40/30 hp) spindle and 50 m/min (1,969 ipm) rapids. The MA-12500H has a 1,250 × 1,250 mm (49.21 × 49.21 in) pallet, a standard 45/37 kW (60/49 hp) spindle and 42 m/min (1,654 ipm) rapids.
