Precision manufacturing refers to the process of producing parts and products to very exact tolerances and specifications. It emphasizes accuracy, repeatability, and high-quality results so that parts fit and function exactly as intended.

In precision manufacturing, the allowable variation (tolerance) is extremely small — often measured in micrometers (µm) or thousandths of an inch.

Precision manufacturing is essential when even tiny differences in size or shape can affect performance, reliability, or safety. Examples include:
