Introduction
The Cnc Machine Ball Screw is a core transmission component that converts rotational motion into linear motion. Through the cyclic rolling of balls between the screw and nut, it achieves high-precision and low-friction transmission. Our ball screws are forged from high-quality bearing steel (GCr15), processed by vacuum quenching and precision grinding, offering excellent wear resistance and stability. They are widely used in CNC machines, automation equipment, precision instruments, and other fields.
product highlights
1. High Precision Transmission
Equipped with full-process precision control technology, positioning accuracy up to ±0.005mm/m, repeat positioning accuracy ±0.002mm, meeting micron-level precision transmission requirements.
Pitch error ≤0.003mm, lead accuracy complies with ISO 3408-3 Class 1/3 standards.
2. High Efficiency & Low Friction
Optimized ball circulation system, transmission efficiency over 90%, 3 times higher than traditional trapezoidal screws, reducing motor energy consumption and heat generation.
High-strength nylon cage reduces ball collision noise, operating noise ≤65dB (no load).
3. Long Service Life
Screw surface treated with hard chromium plating (thickness ≥15μm) or black oxidation, corrosion resistance increased by 50%, suitable for wet and dusty industrial environments.
Designed according to L10 life standard, rated dynamic load (C) and static load (C0) optimized by FEA analysis, service life 20% longer than industry standard.
4. Customizable Adaptation
Cnc Machine Ball Screw Supports full specification customization for screw diameter 6mm~120mm and lead 2mm~100mm, compatible with flange type, nut type, and other installation methods.
Offers personalized configurations such as preload adjustment, special surface treatment (e.g., Teflon coating), and dust-proof components (e.g., bellows, seals).
