Descriptive Summary

 
Title: Guide to the Keller Mechanical Engineering Corporation Collection, 1916-1962
Dates [inclusive]: 1916-1962
Abstract: The Keller Mechanical Engineering Corporation (KME) was an integral part of the manufacturing industry in the United States in the early twentieth century. Keller machines created in the original factory on the Brooklyn waterfront were purchased by companies in Philadelphia, Upstate New York, Detroit, and England. By 1940, the company merged with Pratt & Whitney and moved to a new state-of-the-art complex in Connecticut. Although KME developed many products, the typical Keller machine was a tracer-controlled, horizontal milling machine, which duplicated molds and dies. The design of the tracer distinguished Keller from other milling machines because it allowed greater precision of patterns and therefore more accurate stamping and forging dies or casting molds. Eventually the automated tracer mechanism gave way to Keller machines with computer numerical control (CNC). Keller machines were essential to the early automotive and aeronautics industries and their design laid the groundwork for modern CAD/CAM (computer aided design/computer aided manufacturing) machines.
