CNC Screws vs. Traditional Cold Heading / Thread Rolling Screws

1. Ultra-high Precision & Geometric Tolerance Control (Core Competitiveness)

• Dimensional accuracy: Linear tolerance ±0.001–±0.005 mm, thread tolerance up to precision grades 6g/4h.
• Geometric tolerances: Concentricity, perpendicularity, and roundness ≤ 0.005 mm, ideal for high-precision assembly and transmission.
• Surface quality: Ra ≤ 0.4–1.6 μm, free of thread cracks and burrs common in cold heading; no secondary polishing required.

2. Strong Material Adaptability (Full Range of High-end Materials)

• Processable materials:
  • Metals: Stainless steel (304/316/17-4PH), titanium alloy (TC4/TC21), superalloy (Inconel 718), aluminum alloy (6061/7075), copper alloy, high-strength alloy steel.
  • Special materials: Medical alloys, insulating alloys, magnetic / non-magnetic materials.
• Advantage: Capable of machining high-hardness, high-toughness, and brittle materials that cannot be formed by cold heading, breaking through traditional process limits.

3. High Customization & Complex Structure Capability

• Non-standard customization: Arbitrary head shapes (cylindrical / countersunk / pan / special), custom threads (fine pitch / left-hand / multi-start / special forms), and composite structures with steps, slots, or holes.
• Complex machining: 5-axis CNC completes multi-sided, angled holes, curved surfaces, and micro deep holes in one clamping; traditional processes require multiple steps and struggle to guarantee precision.

4. Batch Consistency & Stability

• Digital control: Program-driven, eliminating human error. Dimensional deviation within the same batch ≤ 0.005 mm, yield rate ≥ 99.8%.
• Traceability: Full-process parameter recording, meeting strict quality traceability requirements in aerospace, medical, and other industries.

5. Balanced Efficiency & Cost (Best Value for Mid-to-high-end Applications)

• Small-batch / custom: Compared with mold-based cold heading, CNC requires no tooling and delivers samples within 24 hours, ideal for R&D prototyping and small-batch customization.
• Mass production: Automated CNC lines enable 24-hour continuous production, with monthly capacity reaching hundreds of thousands to millions of pieces; overall cost is superior to multi-step traditional processes.
