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 Millac 44R appears in the listed figures as a No. 50 (BT50 / CAT50) vertical machining center with box ways on all axes, a 15/11 kW (20/15 hp) spindle motor, a 30-tool standard magazine and a machine weight of approximately 18,000 kg (39,683 lb). The control is the Okuma OSP-P300M, and Thermo-Friendly Concept is listed as standard.

Those rows describe a heavy, rigid machine. A No. 50 taper and box ways are what a shop chooses for large cutters and interrupted cuts in steel and cast iron, and 18,000 kg of machine weight is in keeping with that. The 15/11 kW (20/15 hp) motor is moderate for the taper size, so the motor, more than the structure, is likely to set the limit on heavy roughing.

The listed travel and table-load rows conflict with one another, so take the travels, table size and table load from the machine's own documentation or nameplate before judging whether a part fits. The same caution applies to the spindle speed and rapid traverse rows. They match those of the far lighter MILLAC 44V II (120–12,000 [20,000] rpm and 50 [30] m/min) and should be confirmed for a No. 50 machine of this weight.

Strengths & Limitations

Strengths

No. 50 (BT50 / CAT50) spindle taper for large cutters and heavy toolholders
Box ways on all axes, according to the listed figures
30-tool magazine as standard
Thermo-Friendly Concept listed as standard, with the Okuma OSP-P300M control
Approximately 18,000 kg (39,683 lb) of machine mass behind the cut

Limitations

The 15/11 kW (20/15 hp) motor is modest for a No. 50 spindle
Listed travel and table-load rows conflict, so the working envelope must be confirmed from the machine's documentation
At approximately 18,000 kg (39,683 lb), the machine needs a suitable foundation and heavy rigging

Best For

Steel and cast-iron milling with No. 50 tooling Interrupted and heavy cuts that benefit from box ways on all axes Shops already tooled for BT50 or CAT50 holders

Frequently Asked Questions

01 What spindle taper and motor does the Okuma Millac 44R have?

The listed figures give a No. 50 taper (BT50 / CAT50) and a 15/11 kW (20/15 hp) spindle motor. A spindle speed row is also listed, but it is identical to the MILLAC 44V II's 120–12,000 [20,000] rpm, so confirm the speed range on the machine itself.

02 What control does the Millac 44R use?

The listed control is the Okuma OSP-P300M, and Thermo-Friendly Concept is listed as standard. When inspecting a particular machine, check the control model on the machine itself against this listing.

03 How heavy is the Millac 44R?

The listed machine weight is approximately 18,000 kg (39,683 lb). Plan rigging, floor loading and foundation around that figure, and confirm it against the machine's nameplate before a move.

04 What are the travels and table load of the Millac 44R?

The listed figures contain two travel rows and two table-load rows that conflict with each other, so neither can be relied on. Take the travels, table size and maximum load from the nameplate or the machine's manual before deciding whether a part or fixture fits.

05 How many tools does the Millac 44R hold?

30 tools in the standard magazine, on a No. 50 (BT50 / CAT50) taper. Tool diameter, length and weight limits are not among the listed figures, and on a No. 50 machine those limits decide which face mills and boring bars can be loaded, so check them on the machine.
