5 Axis CNC Machining Services for Complex, High-Precision Parts
IATF 16949:2016 certified 5 axis CNC machining for metals and plastics. Machine up to five sides in a single setup, from prototype to full production.
What Is 5 Axis CNC Machining?
5 axis CNC machining is a manufacturing process where a cutting tool moves across five different directions at the same time. In addition to the standard left-right (X), forward-back (Y), and up-down (Z) movements, the machine also rotates the tool or the part along two extra axes (A and B). This means the cutter can reach almost any angle on the workpiece without stopping to reposition it.
The result is that complex shapes like curved surfaces, deep pockets, undercuts, and angled holes can all be cut in a single setup. There is no need to unclamp the part, flip it over, and re-align it. This "done in one" approach saves time, removes the chance of alignment mistakes between setups, and produces tighter tolerances of up to ±0.005 mm.
5 axis machining is one of several precision processes Meco performs as part of our custom CNC machining services. We also offer 3 axis CNC for simpler flat parts and 4 axis CNC for multi-sided components. All work runs under our IATF 16949:2016 quality system with full material traceability from start to finish.
Why 5 Axis CNC Machining for Your Parts
5 axis machining is the go-to process for parts that are too complex for standard machines. It handles curved surfaces, compound angles, and deep cavities that would normally need multiple setups on a 3 axis machine. It is the standard choice for aerospace, medical, and high-performance automotive components.

Ultra-Precision: ±0.005 mm
Simultaneous 5 axis motion holds tolerances that 3 axis machines simply cannot reach. CMM inspection to ±0.002 mm confirms every critical dimension.
Vertically Integrated
Machining, surface finishing, heat treatment, and assembly under one roof. One PO, one quality system, shorter lead times.
Any Material, Any Volume
Aluminum, titanium, stainless steel, carbon steel, brass, copper, plus Nylon, Delrin, and PEEK. From 10 pieces to 10 million+. No minimum order.
DFM Before Cutting
Our engineers review your CAD files for tool access, wall thickness, and tolerance stacking before production starts. This catches issues early and saves 15-30% on part cost.
Our 5 Axis CNC Machining Capabilities
Both simultaneous and positional (3+2) machining modes to match your part complexity and budget.
Simultaneous 5 Axis
All five axes move at the same time during cutting. This is required for sculpting organic shapes like turbine blades, impellers, and medical implants where the tool must continuously change angle along a curved path.
- Organic contours and freeform surfaces
- ±0.005 mm ultra-precision
3+2 Positional Machining
The two rotary axes lock at a fixed angle, then the machine cuts using 3 axes. Think of it as tilting the part to a specific position and holding it there while the tool works. Great for angled holes, flat surfaces at compound angles, and multi-face parts.
- Angled holes and flat pockets
- Lower cost than full simultaneous
Superior Surface Finishes
By keeping the cutting tool at the best angle relative to the surface, 5 axis machining produces smoother results with less vibration. This means less secondary polishing or grinding, saving both time and money on finishing steps.
- Ra 0.4 microns achievable
- Reduces post-machining finishing

5 Axis CNC Machining FAQ
What is 5 axis CNC machining?
5 axis CNC machining is a process where a cutting tool and workpiece move across five directions at the same time (X, Y, Z plus two rotary axes). This lets the tool reach almost any angle on the part, so complex shapes like curved surfaces, undercuts, and deep pockets can all be cut in a single setup without stopping to reposition.
What is the difference between 3+2 and simultaneous 5 axis?
3+2 (positional) locks the two rotary axes at a fixed angle, then cuts using three axes. It is best for angled holes and flat features at compound angles. Simultaneous 5 axis moves all five axes at the same time during cutting. It is required for sculpting organic shapes like turbine blades, impellers, and medical implants.
What materials can be 5 axis machined?
Most metals and engineering plastics work well: aluminum, stainless steel, carbon steel, titanium, brass, bronze, copper, plus Nylon, Delrin (POM), PTFE, and acrylic (PMMA). The key is matching the right cutting tools and speeds to each material for the best surface finish and tool life.
What tolerances can 5 axis CNC achieve?
Standard 5 axis machining holds ±0.01 mm. For ultra-precision work (aerospace, medical implants), we achieve ±0.005 mm. CMM inspection to ±0.002 mm is available for verification of critical dimensions.
Is 5 axis machining more expensive than 3 axis?
The hourly machine rate is higher, but 5 axis often costs less per part overall. Because the part is machined in one setup instead of three or four, you save on fixture costs, setup time, and labor. For complex parts, the total project cost is frequently lower than running multiple setups on a 3 axis machine.
What industries need 5 axis machined parts?
Aerospace (turbine blades, structural brackets), medical (implants, surgical tools), automotive (turbo housings, EV components), defense, energy/turbine, and any application where complex geometry and tight tolerances are required. Meco serves 10+ industries from our IATF 16949:2016 certified facilities.
