In CNC machining, "tolerance" refers to the allowable deviation from a specified dimension. Tight tolerances, also known as high tolerances or close tolerances, refer to a narrow range of allowable deviation from the specified dimension. In other words, parts and components that are machined with tight tolerances must be very precise and accurate, with minimal variation from the intended size or shape.
Tight tolerances are often required for parts that need to fit together or work in conjunction with other components, or for parts that are subject to high levels of stress or wear. Achieving tight tolerances requires precise control of the machining process, as well as the use of high-quality raw materials and cutting tools.
In general, the more precise and accurate the final product needs to be, the tighter the tolerances will be. CNC machining is well-suited for producing parts with tight tolerances, as the technology allows for precise control of the machining process and the ability to produce consistent, repeatable results.
