What is High Tolerance Machining?

High tolerance machining (HTM) refers to the process of manufacturing components to extremely precise specifications. Tolerances indicate the permissible limits of variation in a part’s dimension, and high tolerance machining ensures these deviations are minimal. Typical tolerances can range from ±0.01 mm to even ±0.001 mm, depending on the application.
