Ultimate Machining and Engineering is a 35,000-sq.ft. manufacturing plant on five acres in the Chicago suburbs, but in another, more important way, this machine shop is ‘all over the place.’ It has a number of critical customers — Caterpillar Inc., the U.S. Dept. of Defense, Parker Hannifin, and Volvo, to list a few — and a range of capabilities: five-axis CNC machining, to customer specifications; precision grinding; sub-assembly of machined parts; laser marking; and CAD and CAM process capability.

Ultimate Machining also has developed EDM processes, plating and coating capabilities, heat-treating operations, broaching operations, grinding, honing, and polishing, as well as welding capabilities.

It will take on small-runs, prototype projects, and design-proof or test-part manufacturing. And, having developed a solid business relationship with one CNC machine builder, it has the confidence to take on all manner of challenging assignments.

An important part of this story is the ingenuity of Ultimate Machining’s founder and president, John Kulczuga. The Polish-born, naturalized American citizen arrived in the U.S. in the early 1980s. “I went to Poland’s Warsaw University of Technology and graduated with a degree in mechanical engineering. I was anxious to do something, and America gave me that opportunity,” he recalled.

He workedin several different machine shops, but he believed he had the talent and determination to start his own business. He rented a shop in Mundelein, Ill., and started Ultimate Machining and Engineering in 1994.
