D&F ifite uburambe bwimyaka 17 ya CNC. D&F irashobora guhimba no gutanga ubwoko bwubwoko bwiza bwumuringa wa bisi nkuko bishushanya kubakoresha cyangwa ibisabwa bya tekiniki.
Bisi yumuringa wa bisi, Ni CNC ikozwe mumabati y'umuringa / aluminium cyangwa umuringa / aluminium. Kubirebire birebire bayobora urukiramende rufite igice cyambukiranya urukiramende cyangwa urukiramende (ruzengurutse), mubisanzwe uyikoresha azakoresha imbaho zumuringa zegeranye kugirango yirinde gusohoka. Ifite uruhare rwo gutanga amashanyarazi no guhuza ibikoresho byamashanyarazi mukuzunguruka.
