6061 / 7075 Cnc Machine Metal Parts Aluminum Stator Assembly Components 0.005mm Machining Accuracy

Our precision aluminum stator housings are manufactured on German Hermle 5-axis machining centers, engineered for electric motor applications that demand complex geometric structures, tight dimensional tolerances and excellent thermal performance. The integrated finned stator ring design combines structural rigidity with optimized heat dissipation, making it ideal for high-performance drive motors and precision motion systems.

By completing all multi-surface milling, drilling, tapping and contour machining in a single clamping setup, we eliminate cumulative positioning errors from secondary fixturing, ensuring perfect concentricity, perpendicularity and positional accuracy across every feature. We support full customization from prototype validation to high-volume production, serving new energy automotive, industrial automation and aerospace clients worldwide.

Each stator housing is fully machined on a Hermle 5-axis machine in a single setup, producing complex radial fin structures, angled mounting faces, precision bore surfaces and distributed threaded holes in one continuous process. This one-clamp approach guarantees perfect alignment between the inner stator bore, mounting flange and cooling fin arrays, a level of geometric integrity that cannot be reliably achieved with conventional 3-axis machining and multiple re-fixturing.

The integrated finned structure is designed to maximize surface area for passive heat dissipation, drawing heat away from the stator winding and maintaining stable operating temperatures for extended motor life. High-grade aluminum alloy delivers an excellent strength-to-weight ratio, reducing overall motor mass while maintaining structural rigidity under dynamic operating loads.

All mounting holes are precision drilled and tapped with consistent thread depth and pitch accuracy, ensuring uniform clamping force and reliable assembly. All edges and corners receive light deburring to remove sharp burrs and break edges, with no cosmetic brushing applied to functional surfaces to preserve critical dimensional accuracy. Our engineering team provides DFM feedback tailored to stator housing design, helping optimize wall thickness, fin geometry and hole placement for improved manufacturability and performance.
