A long history built on quality performance

Keller Technology Corporation (KTC) was founded in 1918 as the Duplex Buffing Machine Company, which offered custom and standardized buffing machines as well as general machine shop services. The company grew as a general machine job shop servicing the local industries of metropolitan Buffalo, New York, and was renamed J & A Keller Machine Company, Inc.

Over the next 40 years, the company grew both in size and capabilities, providing machine assembly building and manufacturing services to customers located throughout the United States. Upon entering the ’80s, the name was changed to Keller Technology Corporation to reflect the company’s expanding global scope of operations and capabilities.
