Woo­den win­dows and doors are the busi­ness of Wil­helm GmbH in Wees. In 2009, they purcha­sed a new CNC pro­ces­sing cen­ter. Initi­al­ly only for stair­ca­se pro­duc­tion, but in order to achie­ve bet­ter capa­ci­ty uti­liza­ti­on, front door pro­duc­tion was also trans­fer­red to this machi­ne. To this end, “NC-Hops” was also expan­ded to include a cor­re­spon­ding frie­ze con­s­truc­tion module.
