Hettner radial drilling machine on the B 51 in the urban area of ​​Bad Münstereifel. Height about 4 m

The Hettner drilling machine factory was one of the largest employers in the Euskirchen region at the beginning of the 20th century . The company had an armature winding shop and a carpenter's shop.

history

The company was founded in Bad Münstereifel in 1901 by Erich Hettner , a son of Hermann Hettner . 1000 drilling machines were produced by 1913. These particularly large and powerful machines were well known and sold worldwide.

From 1933 the company took part increasingly in rearmament.

After Erich Hettner's death, Else Doering and Grete Hettner took over management, and from 1940 the company was a limited partnership . Up to 35 forced laborers had to work at Hettner during the war . After the war ended in 1945, part of the factory was expropriated and dismantled.

After the death of Grete Hettner 1968 Felix was liver owner of the company, which then Hettner drill factory F. Liver & Co. said. On May 26, 1970, the company ceased to exist in the commercial register.

Because of its historical importance, one of the large radial drilling machines was erected in the middle of a roundabout on the B 51 near Bad Münstereifel as an industrial monument .

Products

The company held the following industrial patents:

  • Patent No. 143040 Tapping Apparatus
  • DE000000718199A Locking and braking device for the rotary casing of a radial drilling machine (registration September 1, 1937)
  • DE000000732451A Device for absorbing the load and stopping the spindle rotation when the thread of the spindle nut is worn (registration March 6, 1940)
  • Radial drilling machine Hettner HR80 E: drilling capacity 80 mm in steel.

The company's product range included drilling machines that were among the largest in the world. For example, they were delivered to South America. Some of these machines are still in operation today. Some of them had an exceptionally high drilling capacity, which enabled large drilling diameters to be drilled in steel. These machines were also used in university research, one example was in the laboratory of the Eindhoven University of Technology .

Insufficient use of the numerical control and a lack of product expansion from the drilling machine to the more modern milling machine could have led to the decline of the company. Production was discontinued in 1965.

Location development

In 1841, under Prussian rule, the Provincial Road Cologne-Trier was expanded, whereupon a grinding mill was built in Iversheim as part of industrialization , and later a cloth factory. This Weber cloth factory burned down on February 1, 1880. In 1890 Münstereifel received a railway connection to Euskirchen with the Erft Valley Railway. In 1900 the area on the railway line was used by the engineer Hettner to build up the company. From 1913 to 1993 the site had its own siding on the Euskirchen - Bad Münstereifel line.

The now listed production hall is located on the B 51 Cologne-Trier just before Bad Münstereifel and is currently used as a horse stable for a leisure center.

Hettner burial site

A listed private cemetery is located near the cemetery near Münstereifel-Iversheim. The first person to be buried there was Anna Unger born in 1918. Glade, the mother of Grete Hettner. The Catholic and Jewish communities had denied the Protestant Ms. Unger burial in their respective cemeteries. The French military administration gave permission for their own burial site. Since 1985, urn burials have only been allowed for family members of the Hettners and families by marriage (Unger, Schaefer, Ubbelohde).
