Our History

During the Second World War (1940-1945), S.A.M.P. (Società Anonima di Meccanica di Precisione), manufactured gears for the Air Force. Due to difficulties in finding tools on the national market, a division for the manufacturing of shaper cutters was set up.

In 1949 this division split off from S.A.M.P. and started up the independent production of gear cutting tools on a world-wide level. The new company was named Samputensili and the production of shaving cutters, hobs and inserted blade hobs, as well as shaper cutters, was born.

In 1957, market development led Samputensili to setting up a sales branch in Germany.

In 1960, Samputensili began researching a machine for hob inspection, enabling the company to make dramatic progress as regards quality and tool manufacturing know how. Given the success of this first machine, Samputensili went on to develop a range of highly sophisticated checking equipment, aimed at testing leads, tooth to tooth indexing error and eccentricity, camshafts, gear or cluster gear rolling on one or two flanks and gear cutting tools. Contemporarily, Samputensili started constructing and modifying both conventional and special machines for internal tool manufacturing requirements; the same machines were sold to some customers on request.

The 1970's marked the start of significant development in the organization of Samputensili production facilities, both in Italy and abroad. The manufacturing of hobs was launched in a new Samputensili plant in Ortona, Central Italy, in 1971 and, in 1974, SU France and Samputensili do Brasil came into being; the latter was to represent a mile-stone for continuous and important development in America.

The first research to develop a new concept in gear chamfering and deburring operations started in 1974 when some Car Industries began looking around for more effective solutions to this problem. The chamfering solution that was consequently engineered proved an immediate success as it guaranteed high-speed, top-quality, controllable performances. In the autumn of 1975 the first machine prototype was exhibited at the International Exposition in Paris. It proved an immediate success and many machines have since been sold to almost all major Car Industries world-wide. The first machines were engineered to work gears and other machines were later manufactured to ensure the rapid working of both shaft and cluster gears.

In 1977, a Shaving Cutter grinding machine was engineered in order to meet internal needs. This machine was later commercialized and sold on the market and has since undergone a technological evolution that has brought about the creation of a reliable full CNC version.

Growth and development into complementary sectors abroad continued into the 1980's. In 1981 a sales branch was opened in England and, in 1982, Samputensili was the first company in Italy to acquire a P.V.D. unit for re-coating tools, utilizing Japanese and Swiss technology.

1985 marked the start of a period that saw Samputensili busy with the realization of its most important process machines: a CNC diamond dresser was designed and mounted on the shaving cutter grinding machine, making it hence possible to increase speed, accuracy and flexibility. The commercialization of RSB 14 was thus launched.

In 1988, thanks to the know how acquired through the construction of process machines for tool manufacturing, Samputensili launched the development and commercialisation of high-accuracy, full CNC gear and worm grinding machines (respectively RI 370 and RV 3000). The technological level attained was such to enable Samputensili to penetrate all main markets world-wide, thus expanding the range of products sold. In the same year the first Samputensili plant in North America was set-up.

In the 1990's Samputensili strengthened its presence in the Far East by setting up production plants in Japan in 1991 and in Korea in 1995 and by opening a sales office in Peking in 1996. In the context of an increasingly global market, Samputensili aimed at creating production facilities in areas where the main constructors operated, while at the same time further integrating its branches and production facilities.

Being sensitive to the importance of the quality of its products and services, Samputensili implemented a formal Management System for the Tool Division in 1996. Three years later the same was done for the Servicing Division (A Division which came about in 1997 to co-ordinate and optimize re-sharpening and re-coating services), in order to bring them into conformity with the required normative of UNI EN ISO 9001. ISO 9001 certification implies advanced process technology, the constant checking of materials, in and post process quality testing and assistance in tool design with a constant commitment to improving internal organization and the products / services that are offered to the customer.

Aware of the importance of being technologically ahead of the market, Samputensili carries out continuous research to improve its products and to develop new technological solutions to meet the needs of its customers. The most recent results of this intense activity are two new products that were integrated into the Samputensili product range in 1999: CBN electroplated grinding wheels and the chamfer-rolling tool. CBN grinding wheels are the results of collaboration with Ernst Winter & Sohn of Hamburg, a product which ideally complements gear grinding machine manufacturing in that this technology enables Samputensili to supply the customer with optimised technical solutions of machines plus appropriate tools. The chamfer-rolling tool, patented internationally, provides the perfect answer to the tricky problem of gear buffing after chamfering operations.

On April 2000 Samputensili concluded the formal acquisition of Hurth Modul, a medium-sized German company that was founded in 1900 by Hermann Pfauter. Hurth Modul production includes CNC hobbing machines for cylindrical gears; the WF series (piece diameter from 15 to 4000 mm) and CNC hobbing machines for spiral bevel gears; the KF series. This acquisition concludes the process of integration which started, from a sales and marketing point of view, in 1998, when the two companies first targeted the world market together. Through the acquisition of the German company, Samputensili has taken a decisive step towards achieving its objective of supplying a complete range of products and relative customer services for the production of gears.

In 2003 Samputensili and Star Cutter Company of Farmington, MI, merged in a 50/50 partnership, creating a company named Star SU LLC through which both companies conduct business. Information concerning the Star SU merger can be found on the website
