Overview
The Okuma MU-8000V Laser EX is a groundbreaking hybrid multi-tasking machining center that integrates 5-axis CNC milling with high-power laser metal deposition (LMD) additive manufacturing in a single platform. This unique combination allows operators to build up near-net-shape features with the laser head and immediately machine them to final precision dimensions without moving the workpiece.
Designed for large, complex workpieces up to 1,900 mm in diameter, the MU-8000V Laser EX excels at repair, refurbishment, and net-shape feature addition on high-value components such as turbine blades, aerospace structural parts, and industrial tooling. The ability to add material and remove it in the same setup eliminates the handling, repositioning, and re-qualification errors that plague conventional repair workflows.
The laser deposition head is fully integrated into the machine's automatic tool changer, allowing seamless transitions between additive deposition and precision 5-axis milling. The high-power fiber laser deposits metal powder layer by layer under an inert gas shield, producing near-wrought material properties compatible with aerospace and medical material specifications.
Okuma's OSP-P300S control manages both the CNC machining and the laser deposition parameters, with Collision Avoidance System protection active during all operations. This is a key enabling technology for aerospace MRO, defense, and energy sectors where conventional replacement of large, expensive components is cost-prohibitive.

Frequently Asked Questions
01
LMD is a directed energy deposition (DED) additive process where a high-power fiber laser melts metallic powder as it is fed through a nozzle, building up material layer by layer. On the MU-8000V, the LMD head is stored in the ATC and called like any other tool, allowing additive deposition and precision 5-axis machining in the same program without removing the workpiece.
02
The MU-8000V Laser EX can deposit a range of metallic powders including titanium alloys (Ti-6Al-4V), nickel superalloys (Inconel 625, 718), stainless steels, tool steels, and cobalt-chrome alloys, covering the most demanding aerospace and energy repair applications.
03
Yes. The laser deposition head is simply one of many tools in the ATC. The machine functions as a full 5-axis machining center and can be used exclusively for subtractive operations when additive capability is not needed.
04
The MU-8000V Laser EX accommodates workpieces up to 1,900 mm (74.8 in) in diameter and 1,582 mm (62.3 in) in height, making it one of the largest hybrid additive machining platforms available.
05
Yes. The laser deposition system requires an inert gas supply (typically argon) for the deposition shield, metallic powder handling and storage equipment, safety enclosures meeting laser Class 4 standards, and specialized ventilation for metal powder fumes. Full site planning with Okuma's applications team is essential.
