What Materials Can Be Machined Using Multi Axis CNC Milling?
Versatility Across Metals, Plastics, and Ceramics
Multi Axis CNC milling—particularly 4 and 5 axis systems—is engineered to handle a wide variety of materials with precision. Its dynamic tool orientation and continuous movement allow for complex features, tight tolerances, and exceptional surface finishes on everything from aerospace metals to engineered plastics and technical ceramics.
Commonly Machined Materials by Category
Aluminum Alloys
Aluminum is ideal for high-speed multi axis machining due to its excellent chip control and thermal conductivity. Common grades include:
Aluminum 6061 – General-purpose structural parts
Aluminum 7075 – Aerospace components with high strength
ADC12 (A380) – Precision housings and cast structures
Multi axis milling enables deep cavity machining, compound angles, and thin-wall features without deformation.
Titanium Alloys
Used in aerospace, medical, and nuclear industries, titanium offers excellent strength-to-weight ratio and biocompatibility. Key grades:
Ti-6Al-4V (TC4) – Common in aerospace frames and implants
Ti-5Al-2.5Sn – Fatigue-critical rotating parts
Multi axis machining reduces tool wear and improves dimensional control during angled or radial cuts.
Stainless Steels
Stainless steel is used in components requiring corrosion resistance, durability, and thermal stability. Popular grades:
SUS304 – Food-grade and structural parts
SUS316L – Medical implants and marine components
SUS630 (17-4PH) – Aerospace fittings and tooling
Multi axis systems support contouring, hole patterns, and intersecting features in stainless steel with fewer setups.
Superalloys
High-performance alloys such as Inconel 718, Hastelloy C-276, and Rene 41 are used in:
Nuclear pressure vessels
High-temperature valves
Multi axis CNC enables smooth engagement, precision finishing, and efficient chip evacuation for these difficult-to-machine materials.
Copper and Brass Alloys
These are widely used for electrical and plumbing components. Common options include:
Copper C110 – High-conductivity busbars
Brass C360 – Precision fittings and valves
Bronze C63000 – Bearings and marine hardware
Multi axis control allows radial hole drilling and high-precision surface finishing on complex geometries.
Engineering Plastics
Plastics machined with multi axis systems offer excellent strength-to-weight ratio, chemical resistance, and electrical insulation. Common types:
PEEK – Aerospace and medical parts requiring biocompatibility
Acetal (POM) – Low-friction gears and bushings
Polycarbonate – Transparent enclosures and safety components
5 axis milling minimizes thermal warping and enables smooth transitions on curved or contoured surfaces.
Technical Ceramics
For high-wear, high-heat, and insulating applications, multi axis CNC milling supports materials such as:
Zirconia (ZrO₂) – Surgical blades and thermal insulators
Alumina (Al₂O₃) – Electronic substrates
Silicon Carbide (SiC) – Abrasion-resistant parts
Multi axis systems reduce tool chatter and allow high-precision finishing passes with controlled engagement angles.
