H62 H65 Brass Purple Copper Cnc Milling Automotive Medical Metal Parts
Product Description
H62/H65 Brass and Pure Copper (Red Copper) CNC Milled Automotive & Medical Metal Components are high-performance, precision-engineered parts manufactured through advanced multi-axis CNC milling technology. Utilizing two distinct material families—H62 and H65 brass (copper-zinc alloys) and pure copper (also known as red or purple copper)—this service delivers components with exceptional electrical and thermal conductivity, natural corrosion resistance, and excellent machinability. H62 and H65 brasses offer a balance of strength, plasticity, and cost-effectiveness, while pure copper provides superior conductivity for specialized applications. From complex automotive system parts to precision medical device components, each part is meticulously crafted to meet exacting specifications, ensuring reliability and performance in critical applications.
Product Processing
Material Selection & Verification: Appropriate copper alloy (H62 brass, H65 brass, or pure copper) is selected based on application requirements (conductivity, strength, corrosion resistance). Certified material stock is verified and cut to optimized blank sizes.
Engineering Analysis & DFM: Technical review of 3D models and drawings to optimize design for manufacturability in copper alloys, considering material-specific characteristics such as chip formation and thermal conductivity.
Advanced CAM Programming: Generation of optimized toolpaths using high-end CAM software, with full simulation to prevent collisions and ensure efficient material removal. Parameters are tuned specifically for brass and copper machining .
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 excellent surface finishes
Feature Machining: Creating complex 3D contours, pockets, threads, and precision holes
Cutting Parameters: Typical cutting speeds of 60-120 m/min, feed rates of 0.1-0.25 mm/rev, and depth of cut of 0.15-0.25 mm
Deburring & Edge Finishing: All edges are meticulously deburred by hand or using automated methods (tumbling, thermal) to ensure safe handling and proper fit.
Surface Finishing & Plating: A range of surface treatments can be applied:
As-Machined: Brass and copper naturally develop attractive finishes even 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
Passivation: For pure copper components
Cleaning: Intensive ultrasonic cleaning to remove all machining residues and surface contaminants.
Final Inspection & Documentation: Each part undergoes final dimensional inspection using CMMs, optical comparators, and gauges. Detailed inspection reports and material certifications are provided.
