Precision Tolerance Control in CNC Machining: How to Achieve 0.002mm Accuracy

Tolerance accuracy is the core standard to measure CNC machining quality. Ordinary mechanical factories can only guarantee ±0.05mm tolerance, while professional high-precision factories can stably control accuracy within 0.002mm, which is critical for precision assembly equipment, hydraulic systems, optical instruments and medical devices.

Key Factors Affecting Machining Tolerance

Machine tool accuracy, tool wear, material deformation, temperature change and fixture positioning accuracy will all affect final dimensional tolerance.

Professional precision manufacturers adopt temperature control workshops, high-precision CNC equipment, imported tools and strict process arrangements to eliminate errors.

Ultra-Precision Processing Technology

Rough machining reserves deformation allowance, finish machining adopts low-speed stable cutting, key precision surfaces adopt grinding and lapping processes to ensure roundness, flatness and dimensional stability.

Wanda CNC provides ultra-tight tolerance CNC machining services, providing complete dimension inspection reports for each batch of precision parts.
