Reishauer looks back on a 200-year long, eventful but successful history. It began in 1788 with hand tools and, in 1930, moved over into building machine tools. In 1945, the cornerstone of today's success was laid with the launch of the first continuous generating gear grinding machine, incidentally one of Reishauer's many inventions.
The Hisey Machine Works was in business by 1899—they would later claim "Established 1896". For their first few years they made a small horizontal milling machine. At the beginning of 1902 they introduced a novel new electric grinder that could be held in a lathe's lantern tool post.

The first coffee mill, made specifically to grind coffee beans, was invented by Englishman Nicholas Book in the late 17th century. Coffee was placed in the top of the lever device and was grinded into a bottom drawer. Thanks to its success, many other inventors and companies put out their own manual devices throughout the 18th century.

With that in mind, Fields designed the GRIND Machine with a 12-foot net around the rim, which forces players to put more of an arch on their shot. That translates into a higher percentage of made shots and muscle memory. "All of the players in the conversation for the best on the planet can shoot the ball," Fields said.

The machine made sure that folks who had to grind up enormous amounts of meat did not get tired from all of the grindings they had to do by hand. To grind meat faster, more comfortable, and more accurately the metal plates that were used to force meat into smaller pieces became blades which electric meat grinders used to grind the meat up.
