The story

Mori Seiki was founded in 1948 by the three Mori brothers. It originally produced textile machinery, but in 1958, the company entered the machine tool manufacturing industry, and by 1968, it began manufacturing numerical control (NC) lathes.

In 2001, grinding machine manufacturer Taiyo Koki joined the DMG Mori Group and in 2002, DMG Mori Co., Ltd. acquired business assets of Hitachi Seiki in Japan. In November 2009, the U.S. headquarters were inaugurated during a four-day event.

In the same year, Mori Seiki Co., Ltd. entered into a strategic partnership with Germany's Gildemeister AG, which controlled the brand DMG. As a result, the US operations of both companies were merged into one unit on April 1, 2010. This partnership with Gildemeister AG led to the renaming of the two entities with the same name of DMG Mori in 2013. In 2016, the Japanese company acquired majority shares of the German company. DMG Mori AG, at their AGM of the same year, approved a corporate transfer of the AG's assets to a wholly owned subsidiary of DMG Mori Co., Ltd., provisionally DMG Mori GmbH.

In June 2018, the Tokyo Digital Innovation Center (DIC) was established, along with the opening of a new plant in Pleszew, Poland the same year.

In 2019, DMG Mori Seiki Co. and Tulip Interfaces formed a partnership to integrate Tulip's software into DMG MORI's equipment.
