Machining bronze rings and plain bearing flange bushings involves precision techniques to ensure dimensional accuracy, surface finish, and performance in applications like bearings or mechanical assemblies. Bronze, typically alloys like phosphor bronze (e.g., C51000) or aluminum bronze (e.g., C95400), is chosen for its wear resistance, corrosion resistance, and low friction in bearing applications. Below is a concise guide to machining these components:
1. Material Considerations
  • Bronze Alloys: Common choices include:
    • Phosphor Bronze: High strength, good for bushings, wear-resistant.
    • Aluminum Bronze: High corrosion resistance, suitable for harsh environments.
    • Leaded Bronze: Easier to machine due to lead content, good for low-speed bearings.
  • Properties: Bronze is relatively soft but can work-harden. Use sharp tools to avoid surface damage.
  • Lubrication: Bronze bushings often operate with oil or grease, so machined surfaces may need grooves or reservoirs.
2. Machining Bronze Rings
Purpose: Bronze rings can serve as seals, spacers, or bearing surfaces in assemblies.
Tools and Setup
  • Lathe: Preferred for cylindrical parts like rings.
  • Cutting Tools: Carbide inserts (K10/K20 grades) or HSS with positive rake angles for clean cuts.
  • Coolant: Use water-based coolant or cutting oil to reduce heat and improve surface finish.
Process
  1. Stock Preparation:
    • Start with bronze rod or tube stock slightly oversized for the final ring dimensions.
    • Face both ends to ensure flatness.
  2. Turning:
    • Rough turn the outer diameter (OD) and inner diameter (ID) to within 0.5 mm of final dimensions.
    • Finish turn with a fine feed rate (0.05–0.1 mm/rev) for smooth surface finish (Ra 0.8–1.6 µm).
  3. Parting Off:
    • Use a parting tool to cut the ring from the stock.
    • Support the workpiece to prevent deformation during parting.
  4. Deburring:
    • Remove sharp edges with a deburring tool or fine abrasive pad.
  5. Inspection:
    • Check OD, ID, and thickness with calipers or micrometers.
    • Ensure tolerances (e.g., ±0.02 mm for precision applications).
Tips
  • Maintain moderate spindle speeds (500–1000 RPM, depending on diameter) to avoid work hardening.
  • Use light cuts to prevent tool chatter and ensure concentricity.
3. Machining Plain Bearing Flange Bushings
Purpose: Flange bushings provide radial and axial support in rotating assemblies, often used in pumps, motors, or gearboxes.
Tools and Setup
  • Lathe or CNC: For turning OD, ID, and flange face.
  • Drills/Reamers: For precise ID boring.
  • Milling (optional): For oil grooves or keyways.
  • Tooling: Similar to rings—carbide or HSS with positive rake.
Process
  1. Stock Preparation:
    • Use bronze bar or pre-cast bushing stock.
    • Face one end and turn the OD to form the flange diameter.
  2. Flange Machining:
    • Turn the flange OD to size, ensuring a flat face for axial load support.
    • Chamfer edges for ease of assembly.
  3. Bore ID:
    • Drill or bore the ID slightly undersized.
    • Finish with a reamer or boring bar for tight tolerances (e.g., H7 fit, ±0.01 mm).
  4. Oil Grooves (if needed):
    • Mill or turn internal grooves (e.g., spiral or cross-hatch patterns) for lubricant retention.
    • Typical groove depth: 0.5–1 mm.
  5. Finish Turning:
    • Polish the ID and flange face to achieve a smooth finish (Ra 0.4–0.8 µm) for low friction.
  6. Inspection:
    • Verify ID, OD, flange thickness, and concentricity.
    • Check for proper fit with mating shaft (e.g., clearance of 0.02–0.05 mm for oil-lubricated bearings).
Tips
  • Use low feed rates for boring to avoid tool deflection in the ID.
  • For high-precision bushings, consider honing the ID after boring.
  • Ensure the flange face is perpendicular to the ID to prevent misalignment.

  • Lubrication: Pre-lubricate bushings with appropriate oil/grease before assembly.
  • Quality Control:
    • Measure critical dimensions with CMM or precision gauges.
    • Test fit with mating parts to ensure proper clearance and alignment.
6. Challenges and Solutions
  • Work Hardening: Use sharp tools and avoid excessive pressure to prevent surface hardening.
  • Tool Wear: Bronze can be abrasive; use coated carbide tools for longer life.
  • Tolerances: For bearing bushings, maintain tight ID tolerances to ensure proper fit and lubrication film formation.
  • Chatter: Reduce speed or increase rigidity (e.g., use steady rests) to minimize vibration.
7. Additional Notes
  • Standards: Refer to ASTM B505 for bronze alloy specs or ISO 4379 for plain bearing tolerances.
  • Sustainability: Recycle bronze chips to reduce waste.
  • Safety: Wear PPE (gloves, glasses) and ensure proper ventilation when using coolant.
