Linsinger Maschinenbau is an Austrian company with headquarters in Steyrermühl, municipality of Laakirchen , Upper Austria . The company's business areas are sawing technology, milling technology, rail technology and tool technology. The company is the global market leader in the rail milling sector. Besides Europe , the most important sales markets are primarily Russia and Asia . The export quota is 99 percent.
history
In 1939 the foundation stone of the Linsinger company was laid in Vienna. Dr. Ernst Linsinger bought the company HW Adler Cie and dealt with the production of small parts. In 1946 Ernst Linsinger (1899–1980) moved his company to Steyrermühl and also changed the company name. Internationally, Ernst Linsinger first drew attention to himself at the beginning of the 1950s with the development and patenting of various whirling devices (called “peeling” by Linsinger) for the production of twisted profiles in rotating bodies.
In 1953 Linsinger patented the first attachments on lathes for thread milling.
In 1957, the first special milling unit followed for trimming strip edges in spiral pipe production. Ernst Linsinger started with the development of "Rapid Milling" (English: Fast Milling). In the mid-1960s, the further development of this process brought about the international breakthrough.
In the mid-1970s, besides the edge milling machines, the construction of thread whirling machines began. The development of pipe cutting according to the vortex principle by means of radially arranged cutting tools with an eccentric movement also falls within this period.
In 1983, the engineers in Steyrermühl developed the first high-speed band trimming machine, with which the “SHF milling process” (conical milling) patented by Linsinger was used.
In 1986 the further development of existing and partly patented machining processes began.
In 1989 the "turbo milling" process was patented. With this method, circular-arc-shaped cutting edges are arranged on the cutter head, which enable a pulling cut. The fast milling speed means a low load on the cutting edges and enables a long service life.
In 1990 the Linsinger company was taken over by the Weingärtner family and the "sawing technology" product range was also introduced: Linsinger began building high-performance cold circular sawing machines for pipes, pipe layers, bolts, rails and non-ferrous metal slabs.
The rail head milling train, first developed and built in 1993, is still in use today.
In 1996, the Wagner company in Reutlingen , Germany was partially taken over . At that time, Wagner was the world's largest manufacturer of circular sawing machines .
In 2001 Linsinger opened a further division with "Tool Technology".
After Linsinger had already developed and built stationary rail head milling systems in 1999, the company acquired the technology for the independent construction of special rail vehicles in 2002. In this context, Linsinger opened a new business area in the area of “independent construction of special rail vehicles”. Since 2004 Linsinger has been building and selling various rail milling and rail processing trains for different areas of application, such as for metros and local rail transport.
In 2005 Linsinger completed the world's largest sheet metal milling machine. The machine is over 100 meters long and 24 meters wide in the area of its two milling units.
Linsinger has been developing and building its own gearboxes since 2008.
In 2011 Linsinger sold the world's largest carbide circular saw machine to Korea . The machine can cut through steel billets with a diameter of up to 800 millimeters. In addition to the DPD (Double Power Drive) transmission patented by Linsinger, the LINCUT system developed by the company is also used in the machine. Here, hard metal cutting inserts are screwed onto the saw blade base. The individual saw teeth can be exchanged.
In 2012, Linsinger carried out the first rail service. Subsequently, the "Rail Services" department was outsourced to the newly founded LINMAG GmbH .
In the same year Linsinger sold the 1000th machine.
Linsinger Maschinenbau Ges.mbH and LINMAG GmbH are organizationally subordinate to Mate GmbH, based in Kirchham .
