Competitive Manufacturing with CNC Milling Machines
DMG MORI has over 100 years of experience with CNC milling machines and comprehensive industry expertise. As a result, the machine tool manufacturer repeatedly sets standards developing versatile and high-performance machining centers. Affordable 3-axis models are just as much a part of the portfolio as universal milling machines for 5-axis simultaneous machining, with which even complex components can be milled efficiently in one clamping.

From 3-axis milling to 5-axis simultaneous machining
Milling machines are designed for 3-axis machining in their simplest form: The tool moves over the workpiece in the X, Y and Z directions. For example, A rotary axis in the headstock or table expands the machining spectrum because components can also be placed at an angle. However, this is only a preliminary stage for 5-axis milling, which machine tool manufacturers implement via a second rotary axis. This allows almost any orientation of the workpiece, so that it can be machined from five sides in one clamping operation. Components made of metal can also be manufactured in complex geometries. Only the machining of the sixth side requires further clamping.
The supreme discipline of milling has developed out of 5-axis technology: 5-axis simultaneous machining. All axes are interpolated, which gives the milling machine maximum versatility. The kinematics of the CNC machine are usually housed in a swivel rotary table, which continuously moves the component while the milling tool removes material. An alternative is head kinematics. Here, the milling head has two round axes to move freely around a workpiece. The 5-axis simultaneous milling enables the production of so-called free-form surfaces, which are common in mold construction, for example.
Overview
CNC milling machines: the most important things to know, in brief
What is CNC milling?
In CNC milling, a milling tool with geometrically determined cutting edges rotates at high speed about its own axis. By advancing the tool or a workpiece in different axial directions, material is removed and a geometric shape is produced. The movement is computer-controlled during CNC milling, i.e., CNC programs define the milling movements.
Where are CNC milling machines used?
CNC milling is one of the basic manufacturing technologies of the metalworking industry. Milling machines can be used to produce, for example, medical implants, automotive components or components for energy generation. There is also the processing of tools and molds, which in turn are required in other production areas, for example injection molds for the production of plastic components.
What is vertical milling?
During vertical milling, the milling tool is guided from above onto a workpiece to be machined. The vertical construction is a very common design of milling machines, because it offers a clearly visible working area.
What is horizontal milling?
If a workpiece is machined horizontally from the side, this is called horizontal milling. The horizontal position of the spindle creates additional room in the workspace, so that larger components or clamping towers with several workpieces can be accommodated. Having chips fall vertically is also a decisive advantage in precision machining and in applications with a high cutting volume.
What is 5-axis milling?
5-axis milling allows almost any desired movement of the workpiece or the milling head, enabling even complex geometries to be achieved in one clamping. On the one hand, this reduces the throughput times, and, on the other hand, increases the accuracy, because deviations due to re-clamping processes are excluded.

More productivity through automated manufacturing solutions and process integration
With a wide range of innovative automation solutions, DMG MORI supports its customers so that they can remain competitive in the global market for the long term. The available products range from standard automation such as PH 150 pallet handling or WH 3 Cell workpiece handling, to Robo2Go Milling as a flexible robot solution, to large round pallet storage systems (RPS) and linear pallet pools (LPP). In addition, driverless transport systems of the AGV series autonomously transport workpieces, pallets or tools from A to B. With its automation expertise, DMG MORI finds a holistic solution for every application.
At DMG MORI, the concept of holistic solutions also includes process integration. In it, the machine tool manufacturer combines different machining processes in one workspace so that complex workpieces can be completely manufactured. In this way, milling machines rotate, interlock and grind components – process steps for which separate machines are used in the traditional way. The result of manufacturing in a single fixture is that the component quality increases significantly and throughput times are drastically reduced.
