Mastering Micro-Tolerances in High-Precision CNC Turning for Automotive Parts: Lessons from a 0.002mm Battle
In high-precision CNC turning for automotive parts, the difference between a part that fits and one that fails can be less than the width of a human hair. This article dives into a real-world case study where we achieved 0.002mm tolerances on a critical transmission component, sharing the process, tooling strategies, and data-driven adjustments that turned a scrap rate of 18% into a consistent yield of 99.2%.
