Umshini wokulungisa i-CNC wenethi yokuphepha kanye nenethi yocingo
Inethi yokuphepha, eyaziwa nangokuthi inethi yokuvikela, isetshenziswa kakhulu kwi-helipad ukuvimbela ukuwa kwezinto ezivela endaweni ephakeme nokuvikela ukuphepha kwabasebenzi. Imodi yomshini: Imishini ye-CNC (Computer Numerical Control) iyindlela yomshini enembile nephumelelayo, engasetshenziswa ukusika, ukubhoboza, ukugaya nezinye izinqubo, futhi ifaneleka kakhulu ekwenziweni kwezingxenye zenethi yokuphepha. Uhlobo: inethi yokuphepha ye-helipad ingahlukaniswa ngezinhlobo ezihambayo nezihleliwe. Imishini ye-CNC ingenza ngezifiso izingxenye zenethi yokuphepha ezinezimo nobukhulu obuhlukene ngokuya ngezidingo ezithile. Izidingo zobuchwepheshe: Inethi yokuphepha kufanele ibe nomthamo othile wokuthwala (okungenani u-122kg/㎡) kanye nezidingo zokuphakama (hhayi ngaphansi kuka-150cm), futhi imishini ye-CNC ingaqinisekisa ukunemba namandla ezingxenye ukuze ihlangabezane nalezi zidingo.
