CNC Screws vs. Traditional Cold Heading / Thread Rolling Screws
CNC screws differ from traditional cold heading and thread rolling screws, with their core advantage lying in CNC cutting + multi-axis linkage, providing irreplaceable benefits in precision, material adaptability, customization, and consistency.
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
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
