| Passivation | 1. Cleaning: Remove contaminants from the surface 2. Chemical Treatment: Submerge in passivation solution (e.g., citric acid) 3. Rinsing & Drying: Thorough rinse and drying to prevent residue | Used for components exposed to moisture or harsh environments |
What are the Key Processes for CNC Machining Brass?
CNC Turning of Brass
CNC turning is ideal for creating cylindrical components like bushings, shafts, and connectors. Here are the key technical requirements for brass turning:
- Tool Selection: Use carbide or high-speed steel tools with sharp cutting edges to maintain precision and prevent burrs.
- Cutting Speed: Brass allows for higher cutting speeds (up to 200-300 meters/min) due to its excellent machinability.
- Feed Rate: A moderate feed rate (0.1-0.3 mm/rev) ensures smooth surfaces without compromising tool life.
- Coolant Usage: Brass machining does not require heavy coolant since the material dissipates heat effectively, but light lubrication can improve surface finish.
- Chip Control: Brass produces small, easy-to-handle chips, reducing downtime for chip removal.
Applications: CNC turned brass parts include bushings, electrical connectors, valve bodies, fasteners, and pump parts.
CNC Milling of Brass
CNC milling is used to create complex shapes, pockets, and features with high precision. Here are the technical aspects to ensure optimal brass milling:
- Cutting Tools: Carbide end mills with sharp cutting edges provide excellent results. For high precision, smaller-diameter tools may be used for intricate features.
- Spindle Speed: High spindle speeds (8,000–12,000 RPM) improve cutting efficiency and surface finish when milling brass.
- Feed Rate and Depth of Cut: A balanced feed rate (0.1–0.2 mm per tooth) and a moderate depth of cut help prevent tool deflection and ensure smooth machining.
- Workholding: Brass parts require secure clamping to prevent movement and maintain tight tolerances during machining.
- Surface Finish Optimization: Light finishing passes are often used to achieve smooth surfaces, minimizing the need for post-processing.
Applications: CNC milled brass parts include heat sinks, manifolds, gears, housings, and decorative components.
