CNC Production & Processing Features
- Focus on miniaturization and lightweight design
- Process micro precision nuts with internal threads from M1 to M3; some watch nuts reach M0.5
- CNC ensures high coaxiality between internal threads and outer contours
- Accurate special-shaped profiles (square, oval, etc.) with slot tolerance ≤ ±0.01 mm
- Smooth, clean surfaces with optional treatments: anodizing, black chrome plating, zinc plating
- Suitable for compact assembly requirements of 3C products, mostly thin and countersunk nuts
- Exquisite appearance and delicate, premium touch matching high-end 3C products
- Internal threads fit tightly with micro bolts for smooth assembly and disassembly
- Ideal for frequent disassembly (e.g., mobile phone repair)
- High precision maintained after long-term use without loosening or thread stripping
Common CNC Machining Challenges & Solutions
Micro Internal Thread Issues: Incomplete thread profile, pitch deviation, and tap breakage. Solution: Use high-precision micro taps with controlled speed and feed rate. Inspect with micro go/no-go gauges.
Surface Treatment Defects: Color difference and coating peeling, especially on edges and corners. Solution: Ensure scratch-free surfaces before processing and strictly control process parameters.
Countersunk Machining Problems: Uneven depth and unsmooth conical surfaces. Solution: Control CNC milling depth, use special countersink tools, and inspect angle and depth.
Batch Processing Efficiency: Balance precision and efficiency for high-volume 3C nut production. Solution: Optimize tapping parameters, use batch fixtures, and regularly check tap wear.
