About Althoff Drehteile
Althoff Drehteile is a family-run, owner-managed company in its fourth generation, based in Königswinter-Oberdollendorf since 1921, and manufactures precision turned parts with diameters from 0.5 to 20 mm in all machinable materials. Production encompasses short turned parts (CNC and conventional), CNC long turning, and multi-spindle automatic lathe production for extremely high volumes. In addition to machining, the company coordinates further processing steps such as deburring, washing, grinding, hardening and surface finishing – parts are delivered ready for installation. Customers include, among others, household and consumer electronics, industrial switchgear technology, and the lock and security industry; turned parts from Althoff production can be found worldwide in everyday electrical appliances and in industrial electrical systems. The company is certified to DIN ISO 9001 and 14001 and was awarded the PHILIPS World Class Supplier Award in Silver and Gold.
