Okuma has just introduced the MU-8000V Laser EX multitasking CNC machine, which combines subtractive manufacturing with laser additive manufacturing technology. The machine uses Laser Metal Deposition (LMD), enabling it to 3D print entirely new items and add material to existing parts for repair or cladding. It can even print with multiple materials in a single build. By integrating LMD with CNC machining, this machine allows for cutting parts into various shapes, adding material, and trimming with precision.

The MU-8000V Laser EX also offers mid-process inspection and repair during production. Efficiency and resolution are enhanced through infinitely variable laser spot diameters, ranging from 0.4 mm to 8.5 mm. Unlike Laser Metal Fusion, LMD technology supports mid-process part inspections, material exchanges, and coolant use within the work envelope. These features result in a faster and more flexible process.

Okuma plans to expand its Laser EX line with additional features in the future. For example, laser hardening will be introduced for carbon steel materials. This process involves heating via laser emission and self-cooling, which reduces warping compared to high-frequency or flame hardening. The machines will also offer case hardening, enabling uniform hardening with less distortion.

A significant advancement will include process-intensive capabilities such as turn hardening and grinding. These processes will allow cutting and grinding on a single CNC machine without requiring a setup change.

Additionally, uniform-width turn hardening will be achieved with a high-output, stable laser. Case hardening on cylindrical surfaces will ensure minimal warping and consistent results.

Finally, the company will offer resin mold repairs, from crack removal to finishing, on a single machine. This feature will accommodate hard-to-cut and high-hardness materials.
