[0002] Precision shafts, sometimes also called precision cores, are shaft components that require high accuracy, such as roundness and runout. These are often non-standard parts, custom-made according to customer samples or drawings. Precision shafts are used in a wide range of applications, including automotive parts, office automation components, home appliance parts, and power tool parts.
