Core Material: 6061-T6 Aluminum Alloy (industry-standard high-cost-performance precision machining aluminum alloy, adapting to the structural strength and lightweight requirements of this part)

Key Performance:

• Tensile strength ≥310MPa, yield strength ≥276MPa, with excellent bending resistance, impact resistance and fatigue resistance
• Density is only 2.7g/cm³, greatly reducing the inertial load of the moving end of the equipment while ensuring structural rigidity
• Natural corrosion resistance, can adapt to complex environments such as outdoor and humidity without additional coating, fully complying with RoHS and REACH environmental protection standards
• Extremely strong dimensional stability, no creep or deformation during long-term use, ensuring the lasting consistency of assembly accuracy

This part adopts 5-axis linkage CNC high-speed precision milling process, integrally cutting and forming from a solid aluminum bar, completely avoiding the hidden danger of structural strength caused by welding/splicing.

• Core processes: large-area cavity hollow milling, complex surface contour processing, high-precision drilling/tapping, precision boring of circular bearing holes
• Auxiliary processes: high-gloss contour chamfering, deburring, surface brushing treatment, ensuring zero interference and no sharp edges on the assembly surface
• Full CNC programming realizes one-time clamping forming of complex special-shaped structures, ensuring the consistency of geometric tolerances of each cavity and hole position

Machining Accuracy:

• Dimensional tolerance: ±0.015mm, strictly matching assembly clearance requirements
• Geometric tolerance: flatness of key load-bearing surfaces ≤0.03mm, coaxiality of multi-hole positions ≤0.02mm
• Surface roughness: Ra≤1.6μm, improving the friction and stability of the assembly contact surface

Usage Requirements:

• Adapt to a wide temperature working environment of -40℃~85℃, can withstand static load ≥1500N and high-frequency reciprocating impact
• No deformation or loosening during long-term use, ensuring the motion accuracy and structural safety of the equipment
• The assembly surface needs to be kept clean to avoid impurities affecting positioning accuracy and bearing capacity

With heat treatment, adopting solution treatment + artificial aging (T6 state) process.

• Core purpose: greatly improve material strength and hardness, enhance fatigue and deformation resistance, eliminate processing internal stress, avoid creep of parts under high load conditions, and ensure long-term stability of structural accuracy.

Natural color brushing treatment, retaining the original metallic texture of aluminum alloy.

• Process advantages: improve surface wear resistance and scratch resistance, enhance the anti-slip property of the assembly contact surface, optimize the appearance texture, facilitate visual inspection and assembly positioning inside the equipment, fully meet environmental protection requirements, and can be used directly without additional coating.

Implement a full-process closed-loop quality control system, strictly complying with ISO9001 quality standards:

• Raw material incoming: spectral material inspection to ensure alloy composition and mechanical performance meet standards
• Processing process: 100% geometric tolerance inspection, real-time monitoring of dimensional accuracy and flatness
• Final product inspection: appearance defect inspection, load strength test, full dimensional inspection, traceable inspection report for each batch
• Pre-delivery: cleanliness inspection to ensure no iron chips and impurities in the cavity and hole position, meeting precision assembly requirements
