Machining and secondary operations
How is burr and edge quality controlled?
Answer
Industries Served HVAC & Refrigeration Electronics Engineering & Quality Considerations Copper's softness requires tuned die clearance to control burr and maintain edge quality. Conductivity-critical dimensions are held to drawing requirements and verified with inspection. Forming behaviour is managed to avoid work hardening and cracking in tight bends.

What an engineer still needs from you
- material and material condition (grade, temper)
- material thickness, plus the key diameter, height and wall thickness
- tolerances, burr direction and the visual acceptance standard
- annual volume - it decides whether tooling is single-hit, progressive or transfer
- surface finish, and any secondary machining, annealing or plating
Next step. Send the drawing for a manufacturability review, or send the part data for a process and cost route.
