About us

Saporiti is privately held, and has been building machine tools since 1946. In the early years, the company focused on horizontal and vertical lathes, as well as milling machines. In the 1970’s, driven by their customer’s request for specialized equipment, Saporiti started to build machine tools to meet specific product demands. Today, they are a world leader in three main markets –processing of balls/seats for the valve industry, long shaft milling and whirling, and fixed-part deep hole drilling of large parts such as injection molding machines.
