Assembly of Sophisticated Mechanical Engineering Components

EMAG Production assembles mechanical, mechatronic, and function-critical assemblies for the mechanical engineering industry – from spindles and turrets to ready-to-install drive units.

Our standard is clear: Every assembly must be dimensionally accurate, easy to install, testable, and process-reliable. To achieve this, we combine precision manufacturing, experienced assembly teams, structured pre-assembly, and documented quality assurance at a high-performance production site.

Subassembly assembly with a high degree of vertical integration

EMAG Production has an exceptionally broad value chain. Many components are manufactured in-house – from precision mechanical parts to spindles, turrets, and slides, all the way to electrical cabinets, base frames, and sheet-metal enclosures. This high level of vertical integration reduces interfaces, improves coordination between manufacturing and assembly, and streamlines the process for technical clarifications.

For customers, this means they receive not just an assembly service, but an industrial partner that combines manufacturing expertise, assembly experience, and quality inspection.

Spindle Assembly: Motorized spindles and high-speed spindles

The spindle is one of the most sensitive assemblies in machine tool manufacturing. Even the slightest deviations in bearing alignment, preload, concentricity, or assembly sequence can affect machining quality, service life, and process reliability.

Our spindle assembly services include the professional assembly of motor spindles, high-speed spindles, and other spindle variants. Depending on your requirements, we handle assembly, testing, bearing replacement, and repairs. Our focus is on precision fits, defined assembly processes, and the precise coordination of all functionally relevant components.

Turret assembly for precision switching and positioning functions

Turrets must deliver tools quickly, accurately, and with consistent repeatability. In turret assembly, we assemble complex mechanical assemblies with high requirements for positioning accuracy, load-bearing capacity, and operational reliability.

Assembly is carried out according to technical specifications, coordinated inspection criteria, and clearly defined work steps. This results in turrets that can be reliably integrated into existing machine and manufacturing concepts.

Drive unit assembly: Coordinated mechanics for reliable motion

Drive units combine power transmission, bearings, guidance, and interfaces into a fully functional unit. In assembly, we therefore focus not only on the individual parts but also on the interaction of the entire assembly.

We assemble drive units for demanding mechanical engineering applications where precision, robust design, and clean interfaces are critical. The result are pre-assembled units that reduce assembly effort for the customer and speed up commissioning.

Clamping device assembly: Chucks, clamping systems, and clamping jaws

Chucks are directly responsible for securely holding workpieces. Precision chuck assembly ensures that chucks, clamping systems, and clamping jaws operate reliably and support the required machining quality.

Our assembly process takes into account mechanical function, repeatability, and the requirements of the future manufacturing environment. This results in ready-to-install clamping assemblies for stable processes in machining operations.

Assemblies & Service installations: Retrofits, pre-assembly, series production, and small-batch production

In addition to new installations, we handle assembly and service installations for projects of various sizes. This includes retrofit projects, pre-assembly, replacement assemblies, as well as mass and small-batch production.

Technical understanding of existing systems is particularly important for retrofit projects. We provide support in the refurbishment, adaptation, and assembly of subassemblies so that machines and systems can continue to operate cost-effectively. For mass and small-batch production, customers benefit from repeatable processes, documented quality, and flexible capacity.

Quality assurance as an integral part of assembly

The assembly of components does not end with the assembly itself. Every functionally relevant subassembly must be inspected, documented, and technically traceable. EMAG Production utilizes modern measurement technology, incoming inspection procedures, measurement reports, and defined quality processes.

Functionally relevant dimensions, supplied components, and critical assemblies are systematically inspected. This ensures consistently high quality – irrespective of whether the project involves individual assemblies, small-batch production, or recurring series assembly.
