Thread grinding is an accurate way to produce internal threads and is an effective choice for tight-tolerance parts. A wide range of internal threads, grooves, ball tracks and other forms can be ground on one machine. Typical parts ground on an internal thread grinder include thread gages and nuts for roller, lead and ball screws.
