Common CNC Machining Problems & Key Points

• Micro internal thread issues: Incomplete thread profile, pitch deviation, and easy tap breakage often occur. High-precision micro taps must be used, with controlled tapping speed and feed rate. Micro go/no-go gauges are used for inspection after processing to avoid mismatching with bolts.
   
• Surface treatment defects: Color difference and coating peeling easily occur after anodizing and black chrome plating, especially at the edges and corners of special-shaped nuts. Ensure scratch‑free and burr‑free surfaces before processing, and strictly control process parameters to avoid uneven oxidation.
   
• Countersunk machining problems: Uneven countersink depth and unsmooth conical surfaces often lead to protrusion or depression after assembly. Control CNC milling depth, use special countersink tools, and inspect countersink angle and depth after processing to ensure tight fitting with components.
   
• Batch processing efficiency issues: Given the high demand for 3C nuts, balance precision and efficiency. Optimize tapping parameters, use batch fixtures to avoid dimensional deviation from frequent clamping. Regularly check tap wear and replace worn taps promptly to prevent thread defects.
