Aerospace Aluminium Machining
Requirements for CNC milling solutions for aluminum machining in the aerospace industry
Aerospace Aluminium Machining imposes the highest demands on machine concepts, process stability, and machining strategies. Aluminium alloys are used for load-bearing structural components such as frames, ribs, stringers, and panels, and must provide maximum strength and dimensional accuracy at minimal weight.
Especially large, thin-walled aluminium structures require highly rigid 5-axis milling machines with excellent vibration damping, high dynamics, and precise axis control. In combination with high-speed cutting strategies, material stresses, thermal effects, and part distortions can be effectively minimized.
Only through stable, reproducible processes can surface quality, tight tolerances, and the required airworthiness of aluminium components be consistently ensured, while maintaining high machine availability and cost-efficient production.
Challenges in Aerospace Aluminium Machining

Comprehensive Chip and Media Management
for Maximum Process Reliability
In aerospace aluminium machining, large quantities of chips are generated, placing special demands on machines, tools, and processes. Chips can accumulate on the workpiece, fixtures, or machine bed, causing potential issues. Without effective chip management, deposits on machine components can significantly compromise precision and repeatability. At the same time, tools may overheat, wear faster, or damage the surface quality of components.
The greatest challenge is to reliably remove chips while maintaining high levels of machining speed, cooling, and process stability. Our integrated chip management and extraction systems ensure that chips are immediately evacuated and the machining area remains clean. This guarantees reproducible surface quality, minimal tool wear, and process-secure production—even for large, thin-walled, or complex aluminium structural components.
Chip Management
Continuous Chip Removal Without Process Interruptions
In aerospace aluminium machining, large volumes of chips are generated. A high-performance chip conveyor ensures their continuous and reliable removal directly at the source.
This keeps the work area, guides, and machine components clean, prevents chip accumulation, and maintains process reliability—even during long production runs and with large components. Controlled chip flow forms the foundation for stable, reproducible manufacturing of high-quality aluminium structural parts.
Milling Head-Chip-, and Ambient Air Extraction
The milling head extraction system with suction hood captures aluminium chips directly at the source, preventing accumulation on the workpiece or in the machining area. This keeps machining zones residue-free, protects tools, and ensures consistently high surface quality of components.
Minimal amounts of aerosols and oil mist are reliably removed from the surrounding air by a powerful ambient air extraction system. This effectively protects employees, improves air quality, and creates a safe and comfortable working environment. At the same time, the machine stays clean, visibility in the work area is optimized, and a stable, process-secure manufacturing environment is maintained.
Efficient Chip Processing and Resource Utilization
In aerospace manufacturing, aluminium chips are generated that represent a valuable raw material. Through briquetting, chips are compacted, residual coolant is removed, and volume is significantly reduced. This simplifies handling, storage, and recycling, lowers disposal costs, increases the value of the chips, and contributes to cost-efficient and sustainable aerospace aluminium machining.
Coolant Temperature Control
Coolant Tempering – Crucial for Stable Processes
Stable process control and consistent quality are essential for sophisticated aerospace components. The tempering of the coolant plays a central role in ensuring dimensional accuracy and reproducibility in aluminum machining.
Constant media temperatures prevent thermally induced dimensional deviations in both parts and machines. Especially for large structural components and long machining times, controlled tempering ensures stable process conditions and high manufacturing precision, a decisive advantage in the production of aerospace components.
Part-Specific Clamping Technology
Ensuring Process-Secure Aluminium Machining
Stable and repeatable clamping technology is crucial in aluminium machining. Aluminium structural components are often thin-walled, large, or complex in shape and can be sensitive to improper clamping forces.
Our turnkey clamping solutions enable precise fixation—whether stress-free or intentionally in a forced position—without compromising part geometry or dimensional accuracy. This ensures that form, surface quality, and good parts are maintained even for demanding aluminium structural components.
Hardtooling
Stability for Series Production
In hard tooling, stress-free clamping is not the primary focus; instead, components are intentionally positioned in a fixed orientation. Custom clamping fixtures (negative molds) combine stability and flexibility and are precisely tailored to your aluminium structural components. Robust base structures and reference elements ensure repeatability and process stability. The fixture also allows selective freeing of specific areas so that they can be machined collision-free. Part holders can be flexibly extended or retracted as needed. This ensures aluminium components are reliably and accurately fixed—even for large, thin-walled, or complex structural parts. As a result, scrap is minimized, dimensional accuracy and surface quality are improved, and production efficiency is significantly increased.
Combined Clamping
For Aluminium Components in Aerospace
Combined clamping systems integrate mechanical clamping methods with controlled pressure and vacuum techniques. This ensures that loads are evenly distributed, allowing even thin-walled or large aluminium structural components to be fixed precisely and stably.
The fixtures incorporate various approaches, from hardtooling and actuator systems to contour-adapted elements, and adapt flexibly to different part shapes and sizes.
Custom Clamping Fixtures
Tailored for Your Aluminium Components
Custom clamping fixtures combine stability and flexibility and are precisely tailored to your aluminium structural components. Robust base structures ensure repeatability and process stability, while contour pieces or part-specific adaptations allow the fixture to accommodate different component shapes.
This ensures that aluminium components are reliably and accurately fixed—even for large, thin-walled, or complex structural parts. As a result, scrap is minimized, dimensional accuracy and surface quality are improved, and overall production efficiency is increased.
Universal Clamping Systems with Actuators
Flexibility for Variant-Rich Aluminium Components
For changing component geometries or small series, actuator systems provide versatile, precise, and controlled clamping forces.
The fixture is designed for a wide range of components and can be flexibly adapted to different shapes, dimensions, and variants—ideal for diverse applications in the aerospace aluminium machining industry.
High-Performance Milling Spindles
for Aerospace Aluminium Machining
For highly productive aluminium machining in the aerospace industry, a high-performance milling spindle with HSK-A63 and up to 30,000 rpm is used. It delivers the necessary spindle power and torque to reliably perform both dynamic roughing and high-precision finishing of complex aluminium structural components.
Optionally, the spindle can be equipped with a D80 for HSK-A63 faceplate, which primarily increases interface rigidity. This allows stable and precise machining even on large components and provides additional machining options without compromising process stability.
The high spindle speeds also enable the use of PCD tools in high-speed applications, which are often required in aerospace for complex contours and fine surface finishes. For the customer, this means shorter machining times, reproducible dimensional accuracy and surface quality, and efficient production—even for complex or large aluminium components: decisive advantages in the production of high-quality aerospace parts.
