Sunnen Italia

What Sunnen Italia does

Sunnen Italia S.r.l. is the Italian distribution, applications, and service subsidiary of US-based Sunnen Products Company (founded 1924), operating from Arese (Milan) with 14 employees. It sells and supports precision honing and lapping equipment — horizontal (SH series), vertical (SV series), Single Stroke (VSS-2), hydraulic cylinder (HTA–HTH, HES), and portable honing machines — alongside proprietary tooling (mandrels, diamond-plated and multi-stone tools, MPS modular systems), abrasives (standard, traditional, and superabrasives including diamond and CBN), cutting fluids, and precision measurement instruments (PGE-6000 electronic gauge, PG series, AG automotive series, bore gauges). The company also holds Italian representation for seven additional international brands: Benzinger, Bridgeport, Colchester, Kellenberger, Karl Klink, Osborn, and Supfina.

The business operates a direct enterprise field-sales model with dedicated sales representatives and customer service teams in Italy, supported by an in-house technical center for process development, custom automation solutions, operator training, and on-site maintenance and repair. Equipment sales are complemented by recurring consumables (abrasives, fluids, replacement tooling) and a 3-year/6,000-spindle-hour warranty program; financing and leasing are offered through partner financial institutions to lower the barrier on high-ticket capital equipment.

End markets span automotive (primary), medical, aerospace, hydraulic, diesel engines, energy, tool and mold making, firearms and defense, and small engines — addressing precision bore sizing, surface finishing, and tolerance control for safety- and performance-critical components. Revenue is not publicly disclosed, the entity is privately held with no external institutional investors identified, and the parent remains Sunnen Products Company, a strategic operating parent headquartered in St. Louis, Missouri.
