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 MCR-BIII is a double-column machining center specified by size instead of sold as one fixed machine. The width between columns starts at 80.71 in, with 100.39, 120.08 and 139.76 in as wider options, and X-axis travel starts at 118.11 in, with longer tables from 157.48 to 472.44 in. The spindle taper is No. 50 (BT 50).

Choosing the machine therefore starts with the part. The column width decides the widest workpiece that can pass between the columns, and the table decides its length. Four widths and a long run of table lengths mean the same model can be a moderately sized plate mill or a machine for beds and frames many metres long.

Five spindle ranges are listed. The standard is 10–4,000 rpm; the bracketed alternatives are 10–3,600, 10–6,000, 30–8,000 and 30–10,000 rpm. The low-speed ranges are the natural fit for large face mills and boring in steel and cast iron, while the 8,000 and 10,000 rpm ranges trade the 10 rpm bottom end for a 30 rpm minimum and suit finishing with smaller tools. Spindle power is 40/30 hp, with 60/50 hp as the option.

Rapid traverse is 590.1 × 787.4 × 590.1 ipm, and the magazine starts at 32 tools with 50, 72, 100, 120 and 180 as options. Table load, the vertical travels and machine weight are not on Okuma's product page and should come from the quotation for the size chosen.

Strengths & Limitations

Strengths

Four column widths: 80.71 in standard, with 100.39, 120.08 and 139.76 in options
X travel from 118.11 in up to 472.44 in on the longest table
Five spindle ranges, from 10–3,600 rpm to 30–10,000 rpm, on a No. 50 (BT 50) taper
60/50 hp spindle option above the standard 40/30 hp
Magazine options up to 180 tools from a 32-tool base

Limitations

The 8,000 and 10,000 rpm spindles start at 30 rpm, giving up the 10 rpm minimum of the lower ranges
Standard magazine is 32 tools; 50 and above are options
Rapid traverse peaks at 787.4 ipm on the fastest axis, and two axes are listed at 590.1 ipm
Table load and the Y and Z travels are not stated among the published rows

Best For

Large plates, frames and bases on tables with up to 472.44 in of X travel Heavy face milling and boring with the 10–4,000 rpm No. 50 spindle Wide workpieces needing up to 139.76 in between columns Long cycles on big parts drawing on magazines of up to 180 tools

Frequently Asked Questions

01 What sizes does the Okuma MCR-BIII come in?

Size is set by two choices. The width between columns is 80.71 in as standard, with 100.39, 120.08 and 139.76 in optional. X-axis travel is 118.11 in as standard, with optional tables from 157.48 to 472.44 in. Pick the column width for the widest part and the table for the longest.

02 What spindle speeds are available on the MCR-BIII?

The standard spindle range is 10–4,000 rpm. Okuma lists four alternatives: 10–3,600, 10–6,000, 30–8,000 and 30–10,000 rpm. All use a No. 50 (BT 50) taper. Power is 40/30 hp as standard and 60/50 hp as an option.

03 How many tools can the MCR-BIII hold?

32 tools as standard, with 50, 72, 100, 120 or 180 tools optional. Large workpieces often need a long list of tools in one clamping, so the magazine size is worth settling together with the table length.

04 How does the MCR-BIII compare with the MCR-A5CII?

Both are No. 50 (BT 50) double-column machines. The MCR-A5CII lists X travels of 3,050 - 12,050 mm (120.08 - 474.41 in) and a 50-tool standard magazine, where the MCR-BIII starts at 118.11 in of X and 32 tools. The MCR-A5CII spindle is listed at 4,000 rpm with 6,000 and 10,000 rpm options, against five ranges on the MCR-BIII.
