4-Axis CNC Milling Services for Complex Precision Components
PRECI5 delivers high-efficiency 4-axis CNC machining services engineered for parts requiring machining on multiple faces without manual re-fixturing. Utilizing an auxiliary rotary axis (A-axis) integrated with standard X, Y, and Z motion, we machine intricate circumferential and peripheral features in a single clamping cycle.
Designed for housings, structural brackets, electrical connectors, and specialized mechanical housings where feature-to-feature positional tolerances are critical.
Technical Infrastructure for 4-Axis Machining
Our precision facility in Shenzhen operates an extensive fleet of Mazak machining centers. With 41 dedicated 4-axis units, we provide the scalability needed to handle fast-turn prototyping through large-volume production runs with process stability.
| Machine Model | Quantity | Machining Travel (X×Y×Z) | Rotation | Max. Spindle Speed | Tool Capacity | Listed Machine Precision |
|---|---|---|---|---|---|---|
| Mazak VCN-430AL | 39 units | 560 × 430 × 510 mm | 360° Continuous | 12,000 rpm | T30 | 0.003 mm |
| Mazak HCN5000 | 2 units | 560 × 430 × 510 mm | 360° Continuous | 12,000 rpm | T60 | 0.003 mm |
*Note: The listed machine precision refers to the manufacturer's positioning/machining specifications. Achievable tolerances on finished parts depend on material characteristics, geometry, thermal conditions, and specific inspection methods.
Benefits of 4-Axis CNC Machining
Selecting 4-axis CNC milling offers substantial cost control and technical advantages over standard 3-axis processes for components with multi-planar requirements.
Reduced Setups
Rotate the workpiece around the A-axis to access four distinct sides in a single clamping cycle, cutting labor handling time and eliminating fixture stacking errors.
Positional Accuracy
Features across multiple surfaces reference identical original datums within one setup, ensuring tighter true position, perpendicularity, and parallelism across planes.
Production Scalability
A dedicated fleet of 41 high-performance Mazak machining centers guarantees high machine uptime, throughput, and cross-batch consistency for volume production.
Circumferential Geometry
Execute continuous helical paths, peripheral drilling, multi-faced tapping, and curved slots on cylindrical surfaces without custom indexers.
Choosing the Right Process: 4-Axis vs. 5-Axis
Aligning your component design with the appropriate machining method avoids over-engineering and keeps piece-part costs low while maintaining design intent.
| Process Attribute | 4-Axis CNC Milling | 5-Axis CNC Machining |
|---|---|---|
| Axis Motion | Indexed or continuous 4th rotary axis (A-axis) | Simultaneous 5-axis dynamic spatial motion |
| Primary Application | Multi-sided housings, brackets, rotated shaft slots | Turbine blades, complex impellers, organic organic profiles |
| Cost Efficiency | Higher for standard multi-plane parts (Lower tooling/CAM cost) | Economical only when extreme contours demand 5-axis |
| Setup Configuration | Minimal (Single or dual setup handles multi-surface) | Ultra-low setups, specialized workholding required |
| Best Fit For | Repeatable, rigid industrial & electronics components | Deep undercuts, medical implants, high-curvature aero components |
Quality Control & Metrology Inspection
Repeatable precision across multi-sided parts requires strict in-process monitoring and end-of-line verification. PRECI5 embeds rigorous QA standards across all 4-axis production lines, utilizing high-precision metrology labs to certify dimensional fidelity before dispatch.
Coordinate Measuring Machines (CMM)
ZEISS and Sirius multi-axis CMMs to verify complex geometric dimensions, true positions, and runout tolerances.
Surface Roughness & Texture Measurement
Precise tactile testers ensuring seal surfaces and sliding interfaces comply with designated Ra and Rz thresholds.
Optical & 2.5D Video Measuring Systems
High-resolution non-contact optical inspection for sensitive edges, small apertures, and intricate peripheral features.
Material & Hardness Verification
XRF spectrometer material composition verification alongside Rockwell and Vickers testing to ensure raw stock integrity.
