How much does the Okuma MA-550V cost?
Estimated price range
Our best estimate for a vertical machining centers (vmc) in this class — not a quote from Okuma. Configuration moves it a long way.
Overview
The Okuma MA-550V is a No. 50 (BT 50) vertical machining center with 1,300 mm (51.2 in) of X travel and 560 mm (22.0 in) in both Y and Z. The table is 1,300 × 560 mm (51.18 × 22.04 in), exactly the X and Y strokes, so no part of the table surface is out of the spindle's reach.
The standard spindle runs 50-6,000 rpm. Okuma lists two faster ranges in square brackets, 50-12,000 rpm and 50-25,000 rpm, which are options. Spindle power is given as 22/15/11 kW (30/20/15 hp); the page does not name the duty rating behind each of the three values or say which speed range they belong to. A 6,000 rpm No. 50 spindle is a roughing tool for steel and cast iron with large cutters. If the work mix leans to aluminium or small tools, one of the optional ranges is what to ask about.
The magazine holds 32 tools, with 48 as the option. Rapid traverse is 40/40/30 m/min (131/131/98 fpm) in X, Y and Z, so the vertical axis is the slow one.
Two neighbours frame the choice. The GENOS M560-V has the same table size, 1300 × 560 mm (51.18 × 22.05 in), with 22/18.5 kW (30/25 hp) of spindle power, 32 tools and a Z rapid of 32 m/min (1,262 ipm). The MA-650V keeps the No. 50 (BT 50) spindle and the same three power values and moves up to a 1,530 × 660 mm (60.23 × 25.98 in) table at 12,000 kg (26,455 lb).

Strengths & Limitations
Strengths
- No. 50 (BT 50) spindle taper for large cutters and heavy cuts
- Table of 1,300 × 560 mm (51.18 × 22.04 in) fully covered by 1,300 mm of X and 560 mm of Y travel
- 560 mm (22.0 in) of Z travel, against a 460 mm (18.11 in) vertical dimension on the GENOS M560-V with the same table size
- Optional spindle speed ranges of 50-12,000 rpm and 50-25,000 rpm
- 32-tool magazine, with 48 tools as the option
Limitations
- Standard spindle speed tops out at 6,000 rpm; the faster ranges are options
- Z rapid traverse is 30 m/min (98 fpm), slower than the 40 m/min of X and Y
- Okuma lists three power values, 22/15/11 kW (30/20/15 hp), without stating the duty rating of each
- No table load or machine weight is given on Okuma's page for this model

Frequently Asked Questions
01
The standard range is 50-6,000 rpm. Okuma lists 50-12,000 rpm and 50-25,000 rpm in square brackets as options. The taper is No. 50 (BT 50) and spindle power is given as 22/15/11 kW (30/20/15 hp), without a statement of which range those values apply to.
02
Travels are 1,300 mm (51.2 in) in X, 560 mm (22.0 in) in Y and 560 mm (22.0 in) in Z. The table is 1,300 × 560 mm (51.18 × 22.04 in), and the maximum machining volume is listed as 1,300 × 560 × 560 mm (51.18 × 22.04 × 22.04 in).
03
32 tools as standard, with 48 listed in square brackets as the option. On a No. 50 (BT 50) machine the holders are large and heavy, so check maximum tool diameter, length and weight in the brochure; Okuma's product page does not state them.
04
Both have a No. 50 (BT 50) spindle, 22/15/11 kW (30/20/15 hp), 32 tools with 48 as the option, and the same rapid traverse. The MA-650V is larger: a 1,530 × 660 mm (60.23 × 25.98 in) table against 1,300 × 560 mm (51.18 × 22.04 in), and 660 mm (26.0 in) of Y travel against 560 mm (22.0 in).
