Meiraku Corporation acquires LAMDA2000 from NIDEC

Meiraku Corporation, a Japanese provider of metal machining and machine tool assembly solutions, has acquired a LAMDA2000 hybrid additive/subtractive 3D system from NIDEC MACHINE TOOL, formerly known as Nippon Densan Corporation, a Japanese manufacturer and distributor of electric motors. The installation of the advanced manufacturing system is scheduled for completion in February 2025.

The LAMDA2000 is expected to empower Meiraku Corporation with enhanced capabilities for producing complex components with intricate surfaces. This system seamlessly integrates additive and subtractive processes – enabling the 3D printing of metals, including reactive materials, without the need for an inert chamber.

With a build envelope of 2,000mm x 1,500mm x 1,000mm, the LAMDA2000 opens doors to the manufacturing of previously unachievable components. Equipped with full five-axis subtractive machining and 3D metal printing capabilities, the system incorporates a unique local shield nozzle and advanced monitoring feedback functions to ensure high-quality and stable metal printing.

Some key features of the LAMDA2000 hybrid system include: monitoring and feedback to control the melt pool in real-time – improving metallurgical results and geometric accuracy; local shielding for reactive materials ensures oxygen exclusion and allows for the printing of reactive materials such as titanium and aluminum without an inert chamber; five-axis control enables additive fabrication and subtractive machining at any angle with rotary table and trunnion; and a compact head design provides easy access to the nozzle and workpiece.

The LAMDA Series, continuously evolving since its introduction in 2019, has seen significant advancements. These include the development of a second-generation shield nozzle, the launch of the LAMDA500 five-axis additive machine, the introduction of the LAMDA5000 with a gantry-type direct-action mechanism, and the integration of an AI-based printing layer status-checking function. Recently, NIDEC delivered a LAMDA system with 5m of X-axis travel – demonstrating its commitment to large-scale additive manufacturing and component repair solutions.
