What Shigiya does

Shigiya is a Japanese-founded manufacturer of precision cylindrical grinders and metal machine tools, tracing its origins to 1911 and operating today through its wholly-owned US subsidiary Shigiya (USA) Ltd., established in 1991 and headquartered in a 12,000-square-foot facility in Schaumburg, Illinois. The company exclusively focuses on grinding technology ("All we do is grind") and produces a broad portfolio that includes GPS and GP series straight CNC cylindrical grinders, GAC/GAS/GAE angular cylindrical grinders, GSU universal grinders, GPH ultra-precision grinders, GPC/GPL compact production grinders, plus specialty machines such as the GPES/GPEL eccentric/polygon grinders, GCMH masterless cam grinder, GNW dual-head grinders, and GPD double-drive grinders. All machines are 100% manufactured at the parent Shigiya Machinery Works Ltd. facility in Fukuyama City, Hiroshima, Japan, and incorporate proprietary Shigiya CNC conversational software, hydrodynamic bearing wheel spindle construction, automatic lubrication, and hand-scraped precision surfaces; flagship models such as the GPEL-30.25 eccentric pin grinder achieve 1-micron accuracy.

Shigiya's customer base spans eight primary verticals: automotive (the lead segment), aerospace, medical, electric/electronics, tool and die, job shop, rubber, and other industrial manufacturers, with applications covering engine and transmission components, surgical instruments and implants, electrical components, and rubber processing equipment. The business model is built on three revenue streams: capital equipment sales (the primary stream), an aftermarket of more than $1 million in stocked spare parts, and service/repair/retrofit/rebuild operations that extend machine life, including a dedicated GPS-30 retrofit program.

Go-to-market combines direct enterprise field sales from the Schaumburg headquarters in the US with a network of more than 40 distributors across North America (USA, Canada, Mexico) and regional partners globally, including TECNO.team GmbH across Germany, Austria, Hungary, and the Netherlands; Benson MFI in Australia; and wholly-owned sales offices in China, Thailand, and Korea. Marketing is driven by trade show participation (IMTS, JIMTOF), the company's product website with configurable search by application and specifications, and periodic Open House/Grand Opening events at headquarters. Pricing is quote-based given the custom-engineered nature of industrial grinding equipment, and no public pricing or revenue figures are disclosed.
