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 U5000 carries the largest motor of the MULTUS U models listed alongside it: 37/30 kW (49/40 hp) of spindle power behind a 15 in standard chuck and a JIS A2-8 spindle nose, with JIS A2-11 as the option. Maximum turning diameter is 650 mm (25.59 in) and the machine holds 40 tools.

Motor size is what separates it from the model below. The MULTUS U4000 has the same nose pair, the same 650 mm (25.59 in) turning diameter, the same 40 tools and the same rapid traverse rates, but lists 22/15 kW (30/20 hp). Going from the 22 kW of the MULTUS U4000 to 37 kW is about 68% more spindle power on an unchanged turning diameter, which points the U5000 at deeper cuts and tougher materials, not at bigger parts.

Spindle speed is listed as 45–4,200 rpm, followed by a second range of 30–3,000 rpm in parentheses. Okuma's page does not say which build the slower range belongs to. A lower top speed usually goes with a larger spindle, so ask whether it applies to the optional JIS A2-11 nose before planning small-diameter work on that version.

Rapid traverse is 1,968 ipm on Xa and Za, 1,574 ipm on Zb and Y, and 980 ipm on Xb; the metric rows give the same rates as 50, 40 and 25 m/min. Okuma lists W, 2S and 2SW spec extensions. Turning length, Y travel and weight are not on the product page, so take them from the brochure for the variant quoted.

Strengths & Limitations

Strengths

37/30 kW (49/40 hp) of spindle power, against 22/15 kW (30/20 hp) on the MULTUS U4000 with the same nose pair and turning diameter
15 in standard chuck on a JIS A2-8 nose, with JIS A2-11 listed as the option
Holds 40 tools for parts with many turning and milling operations
Rapid traverse of 1,968 ipm on Xa and Za and 1,574 ipm on Zb and Y
Available in W, 2S and 2SW spec extensions

Limitations

Maximum turning diameter stays at 650 mm (25.59 in), the same as the MULTUS U4000, so the larger motor does not bring a larger part
A second speed range of 30–3,000 rpm is listed without saying which configuration it applies to
Xb rapid traverse is 25 m/min (980 ipm), half the Xa and Za rate
The JIS A2-11 nose is optional, not standard

Best For

Heavy roughing within a 650 mm (25.59 in) turning diameter Tough materials that need 37/30 kW (49/40 hp) at the spindle Chucking work on the 15 in standard chuck Multi-operation parts using the 40-tool capacity

Frequently Asked Questions

01 How does the MULTUS U5000 differ from the MULTUS U4000?

In spindle power. The MULTUS U5000 lists 37/30 kW (49/40 hp) and the MULTUS U4000 lists 22/15 kW (30/20 hp). The spindle nose pair (JIS A2-8, optional JIS A2-11), the 650 mm (25.59 in) maximum turning diameter, the 40-tool capacity and the rapid traverse rates are the same on both.

02 What is the spindle speed of the MULTUS U5000?

Okuma lists 45–4,200 rpm, with 30–3,000 rpm shown after it in parentheses. The page does not state which configuration the slower range belongs to, so confirm the range for the nose and chuck you intend to order.

03 What chuck and spindle nose does the MULTUS U5000 have?

The standard chuck size is 15 in and the spindle nose is JIS A2-8. A JIS A2-11 nose is listed in square brackets as the option. Maximum turning diameter is listed as 650 mm (25.59 in).

04 Which versions of the MULTUS U5000 does Okuma list?

Okuma lists the spec extensions W, 2S and 2SW. The product page does not describe what each adds, and the 40 tools, the rapid traverse rates and the 37/30 kW (49/40 hp) spindle power are given for the model as a whole. Ask for the spindle and axis list of the variant you are quoted.
