CNC Machined 6061-T6 Aluminum Alloy Power System End Cover with 5-axis Milling and ±0.01mm Tolerance
CNC Machined Aluminum Alloy Power System End Cover
High-precision CNC machined end cover designed for demanding power transmission applications in new energy vehicles and industrial systems.
Application & Purpose
Used in new energy vehicle motors, industrial reducers, and power transmission systems as a sealing end cover and structural support for core power components. Provides sealing protection and precise positioning for internal transmission parts, adapts to high-speed and high-vibration working conditions, and ensures long-term stable operation of the power system.
Material Specifications
Material 6061-T6 Aluminum Alloy
Tensile Strength ≥310MPa
Yield Strength ≥276MPa
Key Properties Excellent fatigue resistance, thermal conductivity, lightweight construction, and good corrosion resistance
Environmental Compliance RoHS and REACH standards
Manufacturing Process
Core Processing: 5-axis CNC milling for complex ribs and sealing cavities, high-precision drilling, tapping, and spigot processing
Auxiliary Processing: Contour chamfering, deburring, and brushing
Production Capability: Full CNC programming ensures sealing surface accuracy and geometric tolerances, suitable for medium-batch high-precision production
Technical Specifications
Dimensional Tolerance ±0.01mm
Hole Position Accuracy ≤0.02mm
Sealing Surface Flatness ≤0.03mm
Surface Roughness Ra ≤1.6μm
Operating Temperature Range -40℃ to 120℃
Performance Requirements No leakage on sealing surface, withstands high-speed centrifugal force and vibration loads, no deformation or cracking after long-term use
Heat Treatment
Process: Solution treatment + artificial aging (T6 condition)
Purpose: Improves material strength and toughness, enhances fatigue and deformation resistance, and ensures structural stability of the power system under high-speed operating conditions
Surface Finish
Finish: Brushed finish (natural color)
Advantages: Retains metallic texture, enhances surface wear and scratch resistance, facilitates sealing fit and visual inspection during assembly, complies with environmental requirements
Quality Assurance
Full-process quality control implemented, including:
  • Incoming material composition testing
  • In-process sealing surface and hole position inspection
  • Final finished product testing (appearance, sealing performance, strength test)
  • Traceable inspection reports provided for each batch
  • Compliance with ISO9001 quality system certification
