Bullard Machine Tool Company
The Bullard Machine Tool Company was a large American machine tool builder. It specialized in vertical boring mills and was largely responsible for the development of the modern form of that class of machine tools.[2]
History
The firm was founded in 1894 by Edward Payson Bullard Sr. (born April 18, 1841, in Uxbridge, Massachusetts, US; died December 22, 1906, in Bridgeport, Connecticut, US[3]). He received formative experience at Colt's Manufacturing Company and Pratt & Whitney Measurement Systems,[3] which were influential development centers for generations of toolmakers.[4] Bullard Sr is believed to have developed the first small boring machine designed to do the accurate work previously performed on the faceplate of a lathe.[5] Roe (1916) says that "Up to that time boring machines were relied on only for large and rough work."[5]
Bullard Sr.'s son, Edward Payson Bullard Jr. (1872–1953), continued the family machine tool business and brought the turret principle to the vertical boring mill, making it a vertical turret lathe.[6] For a while in America during the 20th century, the name "Bullard" on the shop floor was something of a genericized trademark for vertical turret-head boring mills.[7] E.P. Bullard Jr led the development of the company's multiple-spindle Template:Visible anchor brand machine that became an important automatic lathe in the mass production of parts for the automotive industry.[1][6] Bullard Jr was president of the company for 40 years, through World War I, the interwar period, and World War II, a period during which the Bullard company was the largest machine tool builder in the U.S.,[6] and vast volumes of military matériel were produced by countless companies running Bullard machines. Bullard is now owned by Bourn & Koch, based in Rockford, Illinois. Bourn & Koch continues to provide OEM parts, service and support for their machines.
