Key Factors for CNC Machining Copper Parts: Comprehensive Analysis from Tool Selection to Machining Accuracy
Copper material has good conductivity, thermal conductivity, and toughness, so it is important to pay attention to the following aspects when machining high-precision and highly corrosion-resistant parts↓↓↓
- Tool selection
Copper material requires certain demands on tools due to its good toughness, and the cutting angle is generally recommended to be between 45 degrees and 60 degrees.
