Our best estimate for a mill-turn / multi-tasking machine in this class — not a quote from Okuma. Configuration moves it a long way.

Overview

The Okuma MULTUS U3000 is a 5-axis mill-turn machine with an 8 in standard chuck, a maximum turning diameter of 650 mm, a 50–5,000 rpm main spindle and a 40-tool magazine. The spindle motor is rated 22/15 kW (30/20 hp).

The rapid traverse row is the most informative line in the table. It names two X axes and two Z axes: Xa and Za at 50 m/min (1,968 ipm), Zb and Y at 40 m/min (1,574 ipm) and Xb at 25 m/min (980 ipm). A second set of linear axes points to a second carriage on at least some versions, and Okuma lists W, 2S and 2SW as specification extensions. The table does not define those codes, so establish which variant a quotation covers and what the b axes carry on it.

With 40 tools the MULTUS U3000 carries twice the magazine of the MULTUS B300II, which lists 20 tools and an 8 in chuck of its own, and its fastest axes run 50 m/min against 40 m/min on the MULTUS B300II. The MULTUS B300II motor is also smaller, VAC 15/11 kW (VAC 20/15 hp) against 22/15 kW (30/20 hp) here.

The standard spindle nose is JIS A2-6 with JIS A2-8 as the bracketed option. Buyers who need the larger nose as standard can look at the MULTUS U4000, which lists JIS A2-8 with JIS A2-11 as its option on the same 22/15 kW (30/20 hp) rating and 40 tools. Work length and milling spindle figures are not in the listed rows for the MULTUS U3000.

Strengths & Limitations

Strengths

40-tool magazine, twice the 20 tools listed for the MULTUS B300II
Rapid traverse of 50 m/min (1,968 ipm) on Xa and Za and 40 m/min (1,574 ipm) on Zb and Y
22/15 kW (30/20 hp) main spindle motor with a 50–5,000 rpm range
JIS A2-6 nose as standard with JIS A2-8 listed as an option, on an 8 in standard chuck
W, 2S and 2SW specification extensions are listed, so the machine can be configured beyond the base layout

Limitations

The Xb axis rapids at 25 m/min (980 ipm), half the rate of Xa and Za
5,000 rpm top speed on the main spindle limits surface speed on small diameters
Work length, milling spindle speed and B-axis range are not in the listed rows
The W, 2S and 2SW extensions are listed without definitions, so quotes must be compared variant by variant

Best For

5-axis milling and turning of chucked parts in one setup Parts up to 650 mm in turning diameter on an 8 in chuck Complex parts that need up to 40 tools in the magazine Mill-turn work with frequent positioning moves at up to 50 m/min

Frequently Asked Questions

01 What are the rapid traverse rates of the MULTUS U3000?

Xa and Za rapid at 50 m/min (1,968 ipm), Zb and Y at 40 m/min (1,574 ipm) and Xb at 25 m/min (980 ipm). The row covers two X axes and two Z axes, so check which of them the variant you are quoted actually has.

02 What spindle does the MULTUS U3000 have?

The main spindle runs 50–5,000 rpm with a 22/15 kW (30/20 hp) motor. The nose is JIS A2-6 as standard with JIS A2-8 as the bracketed option, and the standard chuck is listed at 8 in. No torque figure is in the listed rows.

03 What do W, 2S and 2SW mean on the MULTUS U3000?

Okuma lists them as specification extensions of the MULTUS U3000, meaning variants of the base machine. The listed rows do not define them. Ask Okuma or the distributor exactly what each adds and which figures in the table change with it.

04 How does the MULTUS U3000 compare with the MULTUS U4000?

The MULTUS U4000 lists a JIS A2-8 nose with JIS A2-11 as its option, where the MULTUS U3000 lists JIS A2-6 with JIS A2-8 as the option. Both show 40 tools, 22/15 kW (30/20 hp) and the same rapid traverse rates, so the larger spindle nose is the difference visible in the listed rows.
