Product Description

Fixed Base CNC Milled Part

High-Precision Fixed Base with AL7075-T6 Aluminum Alloy

The fixed base is crafted from high-strength aluminum alloy AL7075-T6 using advanced precision CNC Milling technology. It features a compact, symmetrical U-shaped design for optimal structural integrity and load distribution. A central through-hole enables precise shaft or rod insertion and positioning. The vertical side walls are thick and of uniform height, with the upper edges slightly chamfered to eliminate stress concentration points and enhance assembly safety.

The lower surface is perfectly flat, equipped with threaded bores at both front and rear ends for secure mounting onto equipment substrates or brackets. The overall design is clean and minimalist, with smooth, continuous internal transitions and no unnecessary features—ensuring reliability and ease of integration.

Manufacturing Process

Step 1: Select AL7075-T6 aluminum rod or plate, perform precise cutting to remove excess material, followed by leveling treatment and stress-relief annealing. This step effectively eliminates residual stresses within the material, preventing deformation during processing or in-service use.
Step 2: Initiate CNC milling to rough-machine the blank, rapidly removing most of the excess material. The preliminary shape—including the U-shaped groove, hole contour, and basic geometry—is established. A machining allowance of 0.2–0.3 mm is reserved for subsequent precision operations, along with preliminary drilling of bottom holes to prepare for final accuracy finishing.
Step 3: Utilize high-precision CNC milling with specialized tools and fixtures to complete the final shaping. The U-shaped support arms, through-hole, and installation hole are precisely machined in one operation, achieving dimensional tolerances within ±0.01 mm. Simultaneously, mirror-finish milling is applied to mating surfaces to ensure exceptional flatness and perpendicularity, enabling seamless, uninterrupted alignment with connected equipment components.
Step 4: Manual deburring and chamfering of the finished base, followed by ultrasonic cleaning to thoroughly remove machining debris, aluminum particles, and oil residues—ensuring a pristine surface ready for coating or direct application.
Step 5: Apply natural hard anodizing directly via electrochemical oxidation. This process forms a dense, high-hardness aluminum oxide protective layer that offers excellent wear resistance, corrosion protection, and long-term durability.
Note: All processes are performed under strict quality control, ensuring consistency, repeatability, and compliance with industrial standards.
