USED OKUMA MU 400VA – 2005

The OKUMA MU 400VA – 2005 is a high-performance 5-axis vertical machining center designed for complex multi-sided machining, precision contouring, and simultaneous 5-axis production. It uses a trunnion-mounted rotary table that allows manufacturers to machine multiple faces of a component in a single setup, reducing fixture changes and improving positional accuracy.

A documented 2005 MU-400VA is equipped with an Okuma OSP E100M-H CNC control, 15.75-inch round trunnion table, 8,000 RPM spindle, 20-station automatic tool changer, CAT 40 spindle taper, through-spindle coolant, chip conveyor, spindle chiller, and automatic pneumatic doors. The machine provides approximately 30 inches of X-axis travel, 18.11 inches of Y-axis travel, and 18.11 inches of Z-axis travel.

The trunnion provides A-axis tilting from +20° to -110° and 360° C-axis rotation, giving the MU 400VA full 5-axis contouring capability. Its 20 HP spindle and CAT 40 tooling make it suitable for a wide variety of aluminum, steel, cast iron, and other industrial components.

WHY CHOOSE OKUMA MU 400VA

The biggest advantage of the OKUMA MU 400VA is its combination of a 5-axis trunnion table, 20 HP CAT 40 spindle, 8,000 RPM speed, and substantial 30 x 18.11 x 18.11-inch work envelope.

The trunnion allows the machine to position a workpiece at multiple angles, making it possible to machine complex geometry without repeatedly removing and repositioning the part. This can reduce setup time and improve positional accuracy.

The 213 PSI through-spindle coolant is also valuable for deep-hole drilling, difficult materials, and improved tool life. The documented machine’s chip conveyor and spindle chiller further support continuous production.

For shops that need a relatively large 5-axis envelope without moving to a much larger machining center, the MU 400VA offers a strong combination of capacity and versatility.

---

WHY BUY USED OKUMA MU 400VA – 2005

Buying a used 2005 OKUMA MU 400VA can give manufacturers access to full 5-axis machining capability at a much lower acquisition cost than a new 5-axis machining center.

The machine is particularly attractive to aerospace suppliers, mold and die shops, job shops, defense contractors, and precision manufacturers that need to machine complex components from multiple directions.

The documented 2005 machine already includes valuable production equipment such as 5-axis full contouring, 8,000 RPM spindle, 20 HP motor, 20-tool ATC, through-spindle coolant, chip conveyor, spindle chiller, and pneumatic doors.

Because this is a 2005 machine, however, condition should be evaluated carefully. Buyers should inspect the spindle bearings, trunnion bearings, A/C-axis backlash, rotary positioning accuracy, ballscrews, linear guides, tool changer, drawbar, OSP control, coolant system, chip conveyor, and machine geometry.

A test cut and 5-axis accuracy verification are highly recommended before purchase.

HOW MUCH DOES A USED OKUMA MU 400VA – 2005 COST?

The used market for the OKUMA MU 400VA is relatively specialized because it is a 5-axis machine with a trunnion table. A documented 2005 MU-400VA was sold by Great American Equipment and was described as being in very good condition. Its configuration included the OSP E100M-H control, 8,000 RPM spindle, 20-tool ATC, CAT 40 taper, 213 PSI through-spindle coolant, chip conveyor, spindle chiller, and 5-axis full contouring.

Because this particular 2005 machine is marked sold rather than currently listed with a public transaction price, the following should be considered a practical market estimate rather than a verified sale price.

USED OKUMA MU 400VA – 2005 PRICE RANGE	ESTIMATED COST
As-Is / High Hours / Needs Work	$20,000 – $30,000
Functional Used Machine	$30,000 – $40,000
Good Condition / Production Ready	$40,000 – $50,000
Excellent / Well Equipped	$50,000 – $65,000
Low Hours / Exceptional Condition	$65,000+

For a 2005 OKUMA MU 400VA in good working condition, I would estimate approximately $35,000–$50,000 USD.

For your inventory listing, I would use $40,000–$50,000 USD as a practical estimated asking-price range for a clean, operational machine with the OSP E100M-H control, 8,000 RPM spindle, 20-tool ATC, CAT 40 taper, 5-axis trunnion, chip conveyor, spindle chiller, and through-spindle coolant.

A machine with significant A/C-axis backlash, spindle wear, control problems, or poor machine geometry could fall below $30,000. Conversely, a low-hour example with excellent 5-axis accuracy, strong service history, probing, additional tooling, and other production options could command $50,000–$65,000+.

The specifications above are based primarily on a documented 2005 machine, so individual machine options should be verified before publishing exact specifications on an inventory listing.
