Collet & Engelhard
The Collet & Engelhard GmbH was a manufacturer of machine tools in Offenbach .
The factory was founded in 1862 with 25 workers by Otto Engelhard and Anton Collet . The two had worked as engineers at Sharpe in England in order to gain experience and get to know each other in the leading industrial country. Foreign trips by German engineers were common at that time and were also supported by the government and viewed as an instrument of economic development . In the first financial year , the company built a total of 37 machines, mainly cutting machines for nuts and bolts based on a Sellers patent, as well as drilling and milling machines . Many other machine tools for machining metal or wood followed later . In the 1870s, other general mechanical engineering products were added, such as riveting presses, rollers or punching. The number of employees was around 100 and the machines were built individually. From around 1890 onwards, series production of around 50–70 pieces was started.
At the last international exhibition in Brussels before the First World War in 1910, Collet & Engelhard gained general interest with their drilling and milling machines, shaping machines and a radiator drilling machine.
During the Second World War, the company built an improved version of the copy milling machine from Keller together with Siemens-Schuckert-Werken .
closure
As a result of the structural change , the company's shareholders' meeting decided to close it in 1971. The remaining 800 employees lost their jobs and the factory equipment was sold.
