Non Standard Customized H62 H65 Brass Cnc Milling Automotive Medical Metal Parts

 

Product Description

Non-Standard Custom H62/H65 Brass CNC Milled Metal Components for Automotive & Medical Applications are high-precision, engineered parts manufactured to exact customer specifications through advanced multi-axis CNC milling technology . Utilizing two premium brass alloys—H62 (containing 60.5-63.5% copper) and H65 (containing 63.0-68.5% copper)—this service delivers components with exceptional machinability, natural corrosion resistance, and an attractive golden appearance . These brasses offer an optimal balance of strength, plasticity, and cost-effectiveness, making them ideal for both functional and aesthetic applications . From intricate automotive system components to precision medical device parts, each component is meticulously crafted to meet demanding requirements for dimensional accuracy, surface finish, and long-term reliability in critical applications .

Product Processing

  1. Material Selection & Verification: Appropriate brass alloy (H62 or H65) is selected based on application requirements. Certified material stock (bar, rod, plate, or custom shapes) is verified for composition and cut to optimized blank sizes.

  2. Engineering Analysis & Custom Design: Technical review of customer 3D models and 2D drawings to optimize design for manufacturability in brass, considering material characteristics such as chip formation and thermal conductivity . Custom non-standard features are carefully evaluated.

  3. Advanced CAM Programming: Generation of optimized toolpaths using high-end CAM software, with parameters specifically tuned for brass machining—including appropriate cutting speeds, feed rates, and tool engagement strategies for excellent surface finish and chip control .

  4. Precision CNC Milling (Core Process): Execution on advanced 3, 4, or 5-axis CNC machining centers using high-performance machining strategies:

    • Adaptive Roughing: For efficient material removal with controlled chip load

    • High-Speed Finishing: For achieving tight tolerances (down to ±0.005mm) and superior surface finishes

    • Feature Machining: Creating complex 3D contours, pockets, threads, undercuts, precision holes, and custom non-standard geometries

    • Typical Cutting Parameters: Cutting speeds of 60-120 m/min, feed rates of 0.1-0.25 mm/rev, depth of cut of 0.15-0.25 mm

  5. Deburring & Edge Finishing: All edges are meticulously deburred by hand or using automated methods (tumbling, thermal) to ensure safe handling, proper fit, and a clean appearance .

  6. Surface Finishing & Plating: A range of surface treatments can be applied:

    • As-Machined: Brass naturally develops an attractive golden finish without extra treatment

    • Polishing/Buffing: Hand polishing for smooth, shiny surfaces ideal for aesthetic components

    • Plating: Nickel, chromium, gold, or silver plating for enhanced corrosion resistance, appearance, or conductivity

    • Clear Coating: For cosmetic applications exposed to elements, preventing tarnish

    • Passivation: For specialized applications

  7. Cleaning: Intensive ultrasonic cleaning to remove all machining residues and surface contaminants.

  8. Final Inspection & Documentation: Each part undergoes 100% dimensional inspection using CMMs, optical comparators, and precision gauges. Detailed inspection reports and material certifications are provided .
