Bukuli limafanizira zida 25 zomwe zimagwiritsidwa ntchito kwambiri pamakina a CNC ndikukuthandizani kusankha yoyenera pakugwiritsa ntchito.
CNC Machining akhoza kupanga mbali pafupifupi zitsulo kapena pulasitiki.Izi zili choncho, pali zida zambiri zomwe zimapezeka pazinthu zopangidwa kudzera pa CNC mphero ndi kutembenuka.Kusankha yoyenera pa pulogalamu yanu kungakhale kovuta, ndipo kumvetsetsa ubwino ndi kugwiritsa ntchito bwino kwa chinthu chilichonse chomwe chilipo kungakhale kofunikira.
M'nkhaniyi, tikufanizira zida zodziwika bwino za CNC, malinga ndi makina ndi matenthedwe, mtengo wake komanso magwiridwe antchito (komanso momwe angagwiritsire ntchito).
Kodi mumasankha bwanji zida za CNC zoyenera?
Mukamapanga gawo kuti likhale lopangidwa ndi CNC, kusankha zinthu zoyenera ndikofunikira.Nawa njira zoyambira zomwe timalimbikitsa kutsatira kuti musankhe zida zoyenera pazokonda zanu.
Tanthauzirani zofunikira zakuthupi: Izi zitha kuphatikiza zofunikira zamakina, kutentha kapena zinthu zina, komanso mtengo ndi kutha kwa pamwamba.Ganizirani momwe mudzagwiritsire ntchito mbali zanu komanso malo omwe zidzakhalemo.
Dziwani zida zomwe mukufuna: Lembani zida zingapo zomwe zimakwaniritsa zonse (kapena zambiri) zomwe mukufuna kupanga.
Sankhani zinthu zoyenera kwambiri: Kuyang'ana nthawi zambiri kumafunika pano pakati pa ziwiri kapena zingapo zomwe zimafunikira pamapangidwe (mwachitsanzo, makina ogwiritsira ntchito ndi mtengo).
M’nkhaniyi, tiona kwambiri sitepe yachiwiri.Pogwiritsa ntchito zomwe zili pansipa, mutha kuzindikira zida zomwe zili zoyenera kwambiri pakugwiritsa ntchito kwanu, ndikusunga pulojekiti yanu pa bajeti.
Kodi malangizo a Hubs posankha zida za CNC ndi ziti?
M'magome omwe ali pansipa, tikufotokozera mwachidule zazinthu zomwe zimagwiritsidwa ntchito kwambiri pa CNC, zomwe zimasonkhanitsidwa poyang'ana ma sheets operekedwa ndi opanga zinthu.Timagawa zitsulo ndi mapulasitiki m'magulu awiri osiyana.
Zitsulo zimagwiritsidwa ntchito makamaka pazochita zomwe zimafuna mphamvu zambiri, kuuma komanso kukana kutentha.Pulasitiki ndi zida zopepuka zokhala ndi mawonekedwe osiyanasiyana, omwe nthawi zambiri amagwiritsidwa ntchito pakukana kwawo kwamankhwala komanso mphamvu zamagetsi zamagetsi.
Poyerekeza ndi zida za CNC, timayang'ana mphamvu zamakina (zomwe zimawonetsedwa ngati mphamvu zokolola), machinability (kusavuta kwa makina kumakhudza mitengo ya CNC), mtengo, kuuma (makamaka zitsulo) ndi kukana kutentha (makamaka mapulasitiki).
Nayi infographic yomwe mungagwiritse ntchito ngati chiwongolero chachangu kuti muzindikire mwachangu zida za CNC zomwe zimagwirizana ndi zofunikira zaukadaulo:
