5-Axis CNC Machining Parts Control
ZH Precision leverages 5-axis CNC machining to perform multi-face machining in a single setup, minimizing clamping errors and ensuring tight dimensional tolerances. Our process control focuses on surface contour, straightness, coaxiality, total runout, positional accuracy, and dynamic balancing. By carefully managing internal stresses, material hardness, and surface treatments, we ensure every part achieves consistent precision, mechanical performance, and readiness for demanding industrial, aerospace, automotive, and medical applications.
Aluminum Impeller 5-Axis Machining
Control Focus:
ZH Precision ensures tight control of outer contours, shaft centerline runout, and assembly fit, with high requirements for dynamic balancing and centrifugal forces. This guarantees bearing life, smooth operation, minimal noise, and optimal rotational performance.
Process Technology:
We combine CNC turning and 5-axis milling to produce high-precision aluminum impellers. Blanks are turned with finishing allowances, then 5-axis milled to achieve tight roundness and exact blade geometry. All machining uses a single coordinate system for the shaft and outer surfaces, ensuring consistent accuracy, minimal stress, and superior aerodynamic performance.
High-Temperature Alloy Impeller 5-Axis CNC Machining
Control Focus:
ZH Precision specializes in 5-axis CNC machining of high-temperature alloys such as Invar. These materials are tough, have low thermal conductivity, and are prone to hardening and deformation during cutting. We carefully control shaft runout, blade geometry, and critical dimensions, using ultra-durable coated tools and low-temperature cutting fluids to minimize heat and maintain precision. Electron beam welding, stress relief, and precision grinding further ensure structural integrity and reliable performance.
Process Technology:
Impellers are machined from CNC-turned blanks and finished with 5-axis milling. For larger production, casting blanks are recommended to optimize material usage, roughing efficiency, and tool life. This workflow ensures tight tolerances, smooth surfaces, and consistent quality for high-temperature alloy impellers used in aerospace, energy, and industrial applications.

What is 5-Axis CNC machining?
5-axis CNC machining combines three linear axes (X, Y, Z) with two rotary axes (A/B or C), allowing the tool or workpiece to move in five directions simultaneously. This advanced configuration enables the machining of complex geometries in a single setup, greatly improving accuracy and efficiency.
By continuously tilting and rotating the part, 5-axis machining minimizes repositioning errors and ensures optimal tool angles for smooth 3D surfaces — ideal for manufacturing impellers, turbine blades, medical implants, and aerospace components.
The result is superior surface finish (up to Ra 0.1 μm), tight tolerances, and shorter lead times, making it the preferred solution for multi-sided, precision-critical parts.
Difference Between Simultaneous 5-Axis and 3+2-Axis CNC Machining
Motion Principle：
- 5-Axis Machining:
All five axes (X, Y, Z plus two rotary axes) move simultaneously and continuously, allowing real-time multi-directional toolpath control. The cutting tool can approach the workpiece from any orientation, making it ideal for machining complex free-form surfaces such as turbine blades, impellers, and medical implants.
- 3+2-Axis Machining:
Also known as positional 5-axis machining, it uses three linear axes for cutting while the two rotary axes lock the workpiece at fixed angles (e.g., a 30° tilt) before machining begins. During cutting, the rotary axes remain stationary, providing excellent accuracy and rigidity for multi-face machining with fewer setups.
Advantages of 5-Axis CNC Machining
1. Complex Geometries – Precisely machine intricate shapes and free-form surfaces from any angle, ideal for aerospace components, automotive parts, and medical implants, reducing multiple setups and simplifying production.
2. Enhanced Accuracy – Minimizes repositioning errors to achieve tight tolerances, ensuring dimensional stability for high-precision industrial, aerospace, and medical applications.
3. Superior Surface Finish – Optimized tool orientation maintains ideal cutting angles, delivering smooth finishes (Ra ≤0.8μm) and reducing secondary finishing for precision automotive, aerospace, and electronic components.
4. Optimized Tool Use – Shorter cutting tools minimize deflection and vibration, producing precise cuts and extending tool life, critical for high-performance metals like titanium, aluminum alloys, and superalloys.
5. Increased Productivity – Combines multiple machining operations into a single setup, reducing lead times and boosting throughput for low- to high-volume production across industrial, automotive, and medical sectors.
6. Material Efficiency – Advanced toolpaths and precise control reduce material waste, essential when working with high-value metals for aerospace, automotive, or energy industry parts.
