5-Axis CNC Machining Capabilities
Our CNC machining services are built around core processes that cover most functional and production-grade requirements, from simple precision parts to complex multi-axis components.
Multi-Surface Machining
Machine angled faces, side features, pockets, and compound geometries with fewer setups.
Complex Contour Machining
Produce curved profiles, transitions, recessed areas, and continuously changing surfaces.
Multi-Directional Feature Alignment
Control bores, interfaces, and mounting features relative to shared datums across multiple orientations.
Integrated Machining and Finishing
Coordinate precision machining with polishing, passivation, anodizing, plating, and painting.
Typical Parts for Five-Axis Machining
Five-axis machining is commonly selected when conventional three-axis setups cannot efficiently reach all features or maintain the required positional relationships between multiple faces.

Complex Housings and Multi-Port Valve Bodies
These parts feature deep cavities, intersecting passages, side openings, angled interfaces, and mounting surfaces distributed across multiple directions. Five-axis machining can complete more features in one setup, improving positional accuracy between bores, sealing surfaces, and internal channels while reducing repeated clamping.
Impellers, Rotors, and Complex Curved Components
This category includes impellers, turbine-style components, rotors, conical parts, and other components with continuously changing curved surfaces. Simultaneous five-axis machining allows the cutting tool to maintain a suitable angle to the surface, supporting smoother finishes, improved blade consistency, and better access to recessed areas.
Multi-Angle Brackets and Spatial Connecting Parts
These components have arms, bosses, inclined holes, curved transitions, and mounting features positioned at different angles. Five-axis or 3+2 machining reduces repositioning, improves alignment between multiple faces, and makes it easier to machine difficult-to-access areas and compound-angle features.
Materials for Five-Axis Machining
We machine aluminum, stainless steel, steel, titanium, brass, copper, zinc alloy, and selected engineering plastics. Material selection is evaluated according to machinability, rigidity, thermal stability, surface-finish requirements, and component application.

Tolerance Control in Five-Axis Machining
Five-axis tolerances are assigned according to part function, datum relationships, material stability, feature accessibility, and inspection requirements. Critical bores, mating surfaces, and multi-directional features may receive tighter tolerances, while non-functional surfaces use practical manufacturing tolerances.
Datum Strategy
Establish shared datums for features machined from different orientations.
Critical Feature Control
Apply tighter tolerances to bores, mating surfaces, and locating features.
Geometry Evaluation
Consider thin walls, deep pockets, tool reach, and component rigidity.
Material Stability
Account for thermal expansion, residual stress, and deformation during machining.
| Category | Standard | Precision Option | Design Guidance |
| General Five-Axis Features | ±0.05 mm | ±0.02 mm | Use standard tolerances for non-critical surfaces and cosmetic features |
| Angled Faces and Multi-Surface Features | ±0.03–0.05 mm | ±0.01–0.02 mm | Define a clear datum system for features machined from different orientations |
| Bores, Bosses, and Mating Interfaces | ±0.02 mm | Up to ±0.01 mm | Apply tighter tolerances where components locate, align, or assemble |
| Complex Contours and Curved Surfaces | ±0.05 mm | ±0.02 mm | Use profile tolerances instead of over-dimensioning individual points |
| Aluminum and Steel Components | ±0.02–0.05 mm | ±0.01 mm for selected features | Stable metals generally support tighter feature-based tolerances |
| Engineering Plastics | ±0.05–0.10 mm | Approximately ±0.03 mm | Consider thermal expansion, deformation, and residual stress |
| Thin Walls and Deep Pockets | Case-dependent | Defined during DFM review | Rigidity, tool reach, vibration, and clamping influence final accuracy |
| Long-Reach or Restricted-Access Features | Case-dependent | Defined during process planning | Tool length and cutting angle must be evaluated before tolerance confirmation |
Actual five-axis machining tolerances are confirmed during DFM review based on material, geometry, datum strategy, feature accessibility, and inspection requirements.
- Single-setup machining can improve alignment between features on multiple faces.
- Deep pockets and long-reach features may require wider tolerances because of tool deflection.
- Metals typically provide more stable dimensional control than engineering plastics.
- Critical bores, mating surfaces, and positional relationships should be identified clearly on the drawing.
Surface Finishing Options for CNC Parts
Surface finishes are selected based on functional needs, appearance requirements, and part usage — not just aesthetics.
