Truline C.N.C., Inc. (originally called Truline Products) was started in 1919
by William Schneider. In a machine shop on Milwaukee's west side they produced, among other things, accessories for the Ford Model T, saw sharpening machines and products for the meat packing industry.

Mr. Schneider was a prolific inventor who's initial invention, the variable pitch fan blade, became the basis for the aircraft industries design of the propeller blade.

In 1978, Truline Products moved to it's present location in Brookfield and changed it's name to Truline C.N.C., Inc. with the purchase of it's first CNC machinery. Since then the business has grown and evolved in to a diverse machine shop using state-of-the-art equipment and highly experienced employees to produce a wide variety of parts and accessories for a broad range of industries.
