Okuma MA-550V vs Okuma MA-650V
Okuma vs Okuma · Vertical Machining Centers
Summary
The Okuma MA-550V and the Okuma MA-650V are two sizes of the same No. 50 (BT 50) vertical machining center. The spindle, magazine and rapids are identical in the table; what changes is the work envelope. The Okuma MA-650V has a 1,530 × 660 mm (60.23 × 25.98 in) table against 1,300 × 560 mm (51.18 × 22.04 in).
The Okuma MA-650V also adds travel in two axes: 660 mm (26.0 in) in both Y and Z against 560 mm (22.0 in). Everything else is shared: 22/15/11 kW (30/20/15 hp) of spindle power, 32 tools with 48 as an option, and 40 / 40 / 30 m/min (131 / 131 / 98 fpm) rapids. On these rows the Okuma MA-550V gives up nothing but size.

Advantages
Okuma MA-550V
- Same No. 50 (BT 50) spindle and 22/15/11 kW (30/20/15 hp) as the larger machine
- Same 32 tools, with 48 as an option, and the same 40 / 40 / 30 m/min rapids
- The smaller 1,300 × 560 mm table suits shops whose parts fit within 560 mm (22.0 in) of Y and Z
Okuma MA-650V
- 1,530 × 660 mm (60.23 × 25.98 in) table against 1,300 × 560 mm (51.18 × 22.04 in)
- 660 mm (26.0 in) of Y travel against 560 mm (22.0 in)
- 660 mm (26.0 in) of Z travel against 560 mm (22.0 in)
Verdict
Choose by part size, because nothing else in the table differs. Shops machining long plates, bars and large steel or iron parts that need the 1,530 × 660 mm table and 660 mm (26.0 in) of Y and Z should choose the Okuma MA-650V. If the work fits a 1,300 × 560 mm table, the Okuma MA-550V delivers the same No. 50 (BT 50) spindle, the same 22/15/11 kW and the same magazine in the smaller size.
