About Linsinger Maschinenbau
Linsinger Maschinenbau GmbH is an Austrian manufacturer of special machines headquartered in Steyrermühl (municipality of Laakirchen, Upper Austria). The family-owned company develops and manufactures milling plants for edge milling of sheet metal plates and steel strips, high-performance cold circular sawing lines for slabs, tubes and profiles, tools for its own machines, as well as mobile and stationary rail processing systems including rail milling machines and special rail vehicles. Well-known in-house developments include the patented SHF milling process (cone milling) and Turbo milling, as well as the DPD dual-drive gearbox with the LINCUT tool system. Steel and non-ferrous metals are machined; carbide cutting inserts are used in the sawing plants. Customer industries include rail processing, offshore wind towers, tube and pipe mills, shipbuilding, the forging industry and automotive. With an export share of 98 percent, the most important sales markets are Europe, Russia and Asia.
