Tight Tolerance Machining: How to Achieve High-Precision CNC Parts What is Tight tolerance machining ? In modern manufacturing, machining tolerance refers to the allowable variation in a part’s physical dimensions, usually expressed as plus or minus values from the nominal size. When components are produced with extremely minimal deviation—often within thousandths of an inch or even microns—they are considered to have tight tolerances. In CNC machining, this level of precision means dimensional variations can be as small as ±0.001 inches (25 microns) or even tighter, depending on the application, material, and part geometry. Achieving tight machining tolerances requires advanced CNC equipment, skilled operators, and strict process control, but the payoff is significant. Precision parts […]
