DMG Mori

What is DMG Mori?

DMG Mori is an international machine tool manufacturer whose machines are widely used in machine shops and machining facilities for CNC machining. The company is especially known for its CNC lathes, machining centers, and turning-milling combination machines (multi-tasking lathe). Its background is a merger of the German DMG tradition and the Japanese Mori Seiki development paths under one brand.

The History of DMG Mori: From DMG and Gildemeister Roots

DMG Mori’s German lineage ties back to Gildemeister, which grew over its long industrial history into a significant machine tool manufacturer. In the 1990s, the machine shop industry went through a major structural change when Friedrich Deckel and Maho merged, and this entity was eventually acquired by Gildemeister. This created the Deckel Maho Gildemeister group, with “DMG” becoming the established abbreviation. This explains why many well-known “Deckel/Maho/Gildemeister” names are still associated with DMG Mori, especially within the European machine tool sector.

The History of DMG Mori: From Mori Seiki to DMG MORI Brand
The Japanese manufacturer Mori Seiki developed along its own timeline, first making machine tools for the metalworking industry and later focusing on NC and CNC technologies. In the 2000s, Mori Seiki expanded its operations and service capabilities through acquisitions and international structures. As the cooperation between Germany’s DMG and Japan’s Mori Seiki deepened, their market presence gradually merged, eventually forming the unified global DMG MORI brand.

DMG Mori’s Merger and Name Changes in Practice

The current structure of DMG Mori was established in stages: first with collaboration and shared sales and service networks, then by standardizing names and uniting everything under the “DMG MORI” brand. In practice, this was seen, for instance, when the German company moved from the Gildemeister name to DMG MORI in the mid-2010s, and the Japanese company also adopted the DMG Mori name. For the machine shop, this change typically resulted in the unification of product lines and documentation: machine names, user interfaces, and service processes were aligned with a consistent logic regardless of region.

DMG Mori in the Machine Shop: Machines and Processes from DMG Mori’s Perspective
DMG Mori’s machine lineup is typically found in the core processes of a machine shop: turning, milling, drilling, and combination machining. In practice, this includes CNC lathes for shaft parts, vertical and horizontal machining centers for prismatic parts, as well as 5-axis machining centers for complex shapes and single-setup operations. The idea of multi-tasking machines (turn-mill) is to combine multiple processes on a single machine, which can reduce setups, improve repeatability, and simplify quality management in the shop.

DMG Mori and Automation in the Machining Shop

In DMG Mori’s solutions, automation is typically related to material handling, palletizing (pallet), robotic cells, and practices for unmanned operation. In the shop, this directly links to throughput times and capacity utilization: when part changeover, fixturing, and process flows are standardized, CAM programming, setups, and production can be tied to a more predictable schedule. Alongside automation, focus is also placed on fixturing solutions and process standardization, especially when aiming for repeatable CNC machining across multiple machines of the same series.

DMG Mori and Digitalization: CELOS, Data Transfer, and Production Transparency

Discussions of DMG Mori’s digitalization often center around the CELOS suite, which serves as the machine’s user interface and application platform. In daily shop operations, this typically involves job management, setup information, maintenance visibility, as well as IoT-enabled data collection and production tracking. The goal isn’t just a “slick control panel,” but rather to ensure the machine’s status, programs, job queues, and maintenance needs are more effectively managed—especially important when machining takes place across multiple cells or factories.

DMG Mori as a Production and Service Network in the Machine Tool Industry

The lifecycle of machine tools in a machine shop is long, so for a company like DMG Mori, after-sales service, spare parts, modernization, and training are just as important as production itself. The practical benefit for a machining facility comes from the machine’s uptime (availability), unified control environments, and accessible services that support production continuity—even when parts, materials, and cutting tools change frequently.

Summary

DMG Mori is a global machine tool manufacturer whose current structure is built on a combination of the German DMG tradition (Deckel–Maho–Gildemeister) and the Japanese Mori Seiki development paths. In the machine shop environment, DMG Mori is particularly associated with CNC lathes, machining centers, 5-axis machining, multi-tasking machines, automation, and CELOS-driven digitalization. The company’s history also explains why various traditional machine brands and product lines, now merged under a single brand and service structure, can still be found under the DMG MORI name.
