Precision Custom CNC Milling for Eccentric Cam Components

Eccentric Cam Made from High-Strength Aluminum Alloy AL7075-T6 via CNC Milling

This component is a precision-engineered eccentric cam crafted from high-strength aluminum alloy AL7075-T6 using advanced CNC milling technology. It features an L-shaped design: one end consists of a cylindrical mounting base with internal threading, designed for secure fastening to trees or structural supports; the opposite end extends into a flat, arm-like cam body with a through-hole at the tip. The bore's center exhibits a clearly defined eccentricity relative to the axis of the mounting base, forming a classic eccentric transmission mechanism essential for precise motion conversion.

Step 1: Precision CNC Milling Process

The manufacturing process begins with the precise cutting and removal of edges and corners from raw AL7075-T6 aluminum alloy stock. A high-precision CNC milling machine then executes fully automated, multi-axis milling operations based on pre-defined digital programs. This single-step operation achieves complex geometries including the eccentric cam profile, mounting openings, and screw fixation holes with exceptional accuracy. The entire process leverages ultra-high-precision CNC technology, ensuring micron-level control over eccentricity and contour tolerance—guaranteeing reliable and repeatable transmission performance within the mechanism.

Step 2: Post-Machining Treatment & Surface Enhancement

After machining, the part undergoes deburring and thorough cleaning to remove any residual debris. It is then subjected to natural anodizing—an electrochemical surface treatment that forms a dense, wear-resistant oxide layer on the aluminum surface. This process preserves the original metallic luster while significantly enhancing surface hardness, corrosion resistance, and durability. Thanks to our mature precision machining system, we ensure not only dimensional accuracy of contours but also optimal dynamic balance—critical for long-term stable operation in automated industrial equipment.
