During the Second World War SAMP (S.A.M.P.) supplies, the Italian air force with precision gears, but the demanding quality requirements forces the Company to produce his own high-precision tools. During these years, the manufacture of shaven and ground cylindrical gears as well as lapped bevel gears continues to expand to support the growing market demand of wire drawing machines. The request for precision and reliability is high, therefore S.A.M.P. decides to start developing its own tool grinding machinery and checking instruments, manufacturing equipment that set the standard at those times. In 1949, S.A.M.P. establishes Samputensili, an ad hoc structure and trademark through which to trade these products.
