Customer Challenge: Manufacturing High-Tolerance & Durable-Appearance Connectors
An industrial equipment manufacturer requires custom 6063 aluminum alloy connectors for its new-generation automated equipment. This part must simultaneously fulfill structural support and connection functions, thus imposing strict requirements on dimensional accuracy, internal structure, and surface durability.
The main challenges faced by the customer include:
- Complex geometry & high precision: The part features a unique L-shaped structure, including multiple precision holes, threaded holes, and complex internal cavities. Its positional and concentricity tolerances are strict, requiring control within 0.05mm.
- Material selection & processing: The customer has specified 6063 aluminum alloy. This material is renowned for its excellent corrosion resistance and ease of extrusion molding, but precise control is required during precision milling to ensure surface quality.
- Surface treatment: To withstand harsh industrial environments, the part needs blackening treatment to enhance its wear resistance, corrosion resistance, and achieve a professional, aesthetic matte black appearance.
RPS Solution: Multi-Axis CNC Milling & Professional Blackening Surface Treatment
As an expert with 20 years of experience in precision parts manufacturing, RPS has provided a perfect one-stop solution for the customer, leveraging its profound technical accumulation in CNC milling and aluminum alloy surface treatment.
We have taken the following key steps:
- Process planning & fixture design: Our engineering team conducted an in-depth analysis of the part’s 3D model. To address the processing of the L-shaped structure and multiple precision holes, we designed customized processing fixtures and planned the optimal processing path. Through multi-step precision milling, we ensured that all complex internal structures were processed under micrometer-level tolerance control.
- High-precision CNC milling: We used high-performance 3-axis and 5-axis CNC milling machines. Especially for deep holes and threaded holes, we adopted high-precision cutting tools and optimized cutting parameters to reduce the impact of cutting force on the parts, ensuring the final dimensional accuracy and surface finish.
- Strict dimensional measurement & quality control: After processing, our quality inspection team used advanced Coordinate Measuring Machines (CMM) to conduct comprehensive measurements of every key dimension and positional tolerance of the parts. We strictly adhere to the ISO9001 and IATF16949 quality management systems to ensure all parts meet the customer’s strict requirements.
- Blackening surface treatment: After processing, we applied chemical blackening treatment (typically black anodization). This surface treatment not only provides a wear-resistant and corrosion-resistant protective layer for the parts but also gives them a deep, professional matte black appearance, meeting the customer’s dual needs for product aesthetics and durability.
