Prince Mfg. Corp., North Sioux City, S.D., makes a variety of components essential to hydraulic systems: pumps, valves, and cylinders—especially cylinders. Prince’s welded hydraulic cylinders are manufactured in four locations, and its Lewis & Clark facility, Yankton, S.D., is a 40,000 ft plant that typically produces as many as 400 cylinders per day in small-batch runs.
As you would expect, Prince is always looking for ways to increase productivity without sacrificing quality. Plant officials at Lewis & Clark identified an opportunity to improve production of a manual skiving-roller burnishing process that required frequent setups and multiple part programs. Discussions with Sunnen Products, St. Louis—well-known for its honing equipment—led to the development of a new automatic skiving and roller burnishing system, the SHD.
