History

On February 7, 1894, 25-year-old Herman Heller founded the company Hermann Heller Handelsgeschäft und Produktion von geschützten Artikeln und Uhrmacherwerkzeug“ – which traded and manufactured patented products and watchmaker's tools. With a staff initially consisting of seven craftsmen and three apprentices, the company produced machinist vices, chimney cowls, fans and spiral stairs.
In 1898, Heller entered the machine building industry by producing cold circular metal sawing machines and saw blade skiving machines as well as thread cutting machines. In 1900, the original company was superseded by Gebr. Heller Maschinenfabrik GmbH founded by the brothers Ernst and Hermann Heller.
In 1940, the firm produced the first milling machines for the machining of crankshafts. After establishing subsidiaries in the UK and Brazil in 1970, Heller opened production facilities in Chicago, IL, USA in 1982.
In the year 2000, the company was awarded certification to ISO 9001, QS 9000, TES and VDA 6.4 standards. In the same year, HELLER doubled the production capacity of the company's production plant in the US and introduced a new internal milling machine for the machining of crankshafts.
In 2007, HELLER introduced the ModuleLine manufacturing system and presented the H series of machining centres at EMO in Hanover. In 2009, the company launched the F series for simultaneous 5-axis machining and in 2010 presented bevel gear machining on 5-axis machining centres from the MCH-C and F series. In 2013, HELLER together with Daimler AG was awarded with the German Innovation Award for Climate and Environment for their arc spraying technology for the coating of cylinder surfaces in automobile engines.
On January 28, 2026, DN Solutions completed the acquisition of Heller's shares. Heller is now a wholly owned subsidiary of DN Solutions.
