The Atlas Press Company bought the Clausing Manufacturing Company in 1950. About 1969, Atlas renamed itself Clausing Industrial. The Clausing Service Center was set up in Goshen, Indiana, in 1974. Although the last of the Atlas lathes was discontinued circa 1981, parts are still handled by the Clausing Service Center, although their Web presence is not as strong as it might be. However, Clausing does maintain an Atlas Old Products page, with old specifications, manufacturing data, and service bulletins. It is presently Under Construction but should eventually be quite useful.
