Machining mwatsatanetsatane zimagwiritsa ntchito kusonyeza fineness wa mankhwala, mongacnc kutembenuza magawondicnc mphero zigawo, ndipo ndi mawu omwe amagwiritsidwa ntchito poyesa magawo a geometric a malo opangidwa ndi makina.Kulondola kwa Machining kumayesedwa ndi kulekerera kalasi.Mtengo wa giredi wocheperako, umakhala wolondola kwambiri.
Pali makalasi 20 olekerera kuchokera ku IT01, IT0, IT1, IT2, IT3 mpaka IT18, pomwe IT01 imayimira kulondola kwambiri kwa gawolo, IT18 imayimira kulondola kwapang'onopang'ono kwa gawolo, makina amigodi wamba ndi a IT7, komanso zaulimi wamba. makina ndi a IT8.Malinga ndi ntchito zosiyanasiyana zamagulu azinthu, kulondola kwa makina ofunikira kuti kukwaniritsidwe ndi kosiyana, ndipo mawonekedwe opangira ndi njira zosankhidwa ndizosiyana.Pepalali likuwonetsa kulondola kwa makina otembenuza, mphero, kupanga, kugaya, kubowola, kubowola ndi mitundu ina yodziwika bwino.
Kutembenuka kwa CNC
Njira yodulira yomwe chogwirira ntchito chimazungulira ndipo chida chotembenuza chimayenda molunjika kapena pamapindikira mu ndege.Kutembenuza nthawi zambiri kumachitika pa lathe, yomwe imagwiritsidwa ntchito pokonza malo amkati ndi akunja a cylindrical, nkhope zomapeto, zowoneka bwino, kupanga mawonekedwe ndi ulusi wazinthu zogwirira ntchito.
Kutembenuka kolondola nthawi zambiri kumakhala IT8-IT7, ndipo kuuma kwapamtunda ndi 1.6-0.8 μ m.
1) Kutembenuza kovutirako kumatengera kuya kwakukulu kodula ndi kuchuluka kwa chakudya kuti apititse patsogolo kusinthasintha popanda kuchepetsa liwiro lodulira, koma kulondola kwa makina kumatha kufika ku IT11 ndipo kuuma kwapamwamba ndi R α 20—10 μ m.
2) Kuthamanga kwakukulu ndi kadyedwe kakang'ono ndi kudula kuya kudzatengedwa momwe kungathekere kwa theka kumaliza kutembenuka ndi kutembenuka.Kulondola kwa makina kumatha kufika IT10-IT7, ndipo kuuma kwapamwamba ndi R α 10-0.16 μ m.
3) Kutembenuza kolondola kwambiri kwa mbali zachitsulo zopanda chitsulo ndi chida chotembenuza cha diamondi chopukutidwa bwino pa lathe yolondola kwambiri kungapangitse kuti makinawo afikire IT7-IT5, ndipo kuuma kwapamwamba ndi R α 0.04—0.01 μ m.Kutembenuka kwamtunduwu kumatchedwa "kutembenuka kwagalasi".
CNC Milling
Kugaya kumatanthawuza kugwiritsa ntchito zida zozungulira zozungulira kuti zidulidwe, yomwe ndi njira yabwino kwambiri yopangira.Ndizoyenera kupanga ndege, poyambira, malo osiyanasiyana opangira (monga spline, zida ndi ulusi) komanso malo apadera akufa.Malingana ndi njira yomweyi kapena yotsutsana ndi liwiro lalikulu la kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka ntchito.
Kulondola kwa makina a mphero nthawi zambiri kumatha kufika IT8~IT7, ndipo kuuma kwapansi ndi 6.3 ~ 1.6 μ m.
1) Kulondola kwa makina panthawi ya mphero ndi IT11 ~ IT13, ndipo kuuma kwapamwamba ndi 5 ~ 20 μ m.
2) Machining kulondola IT8~IT11 ndi pamwamba roughness 2.5~10 mu theka mwatsatanetsatane mphero μ m.
3) Kulondola kwa makina pa mphero yolondola ndi IT16 ~ IT8, ndipo kuuma kwapamwamba ndi 0.63 ~ 5 μ m.
Kukonzekera
Planning ndi njira yodulira yomwe imagwiritsa ntchito planer kuti ipangitse kusuntha kozungulira kozungulira kozungulira pa chogwirira ntchito, chomwe chimagwiritsidwa ntchito kwambiri pokonza magawo.
Kulondola kwa makina a planing kumatha kufika IT9~IT7, ndipo kuuma kwapamtunda ndi Ra6.3 ~ 1.6 μ m.
1) Kulondola kwa makina okhwima kumatha kufikira IT12 ~ IT11, ndipo kuuma kwapamwamba ndi 25 ~ 12.5 μ m.
2) The semi kumaliza Machining molondola akhoza kufika IT10 ~ IT9, ndipo pamwamba roughness ndi 6.2 ~ 3.2 μ m.
3) Kukonzekera bwino kwa kumaliza kumatha kufika IT8~IT7, ndipo kuuma kwapansi ndi 3.2 ~ 1.6 μ m.
kugaya
Kugaya kumatanthauza njira yogwiritsira ntchito zida zowonongeka ndi zowonongeka kuti zidulire zinthu zowonjezera pa workpiece, zomwe zimakhala zomaliza ndipo zimagwiritsidwa ntchito kwambiri pamakampani opanga makina.
Kupera nthawi zambiri kumagwiritsidwa ntchito pomaliza ndi kumaliza, ndi kulondola kwa IT8~IT5 kapena kupitilira apo, ndipo kuuma kwapamwamba kumakhala 1.25~0.16 μ m.
1) Kuuma kwapamtunda kwa mphesa molondola ndi 0.16 ~ 0.04 μ m.
2) Ultra mwatsatanetsatane akupera pamwamba roughness ndi 0.04-0.01 μ m.
3) Kuuma kwapamwamba kwa galasi kugaya kumatha kufika 0.01 μ M pansipa.
Kubowola
Kubowola ndi njira yofunikira yopangira dzenje.Kubowola kumachitika pamakina obowola ndi lathes, kapena pamakina otopetsa kapena makina ophera.
Kulondola kwa makina pakubowola kumakhala kochepa, nthawi zambiri kumafika ku IT10, ndipo kuuma kwa pamwamba kumakhala 12.5 ~ 6.3 μ m.Pambuyo pobowola, kubwezeretsanso ndi kubwezeretsanso nthawi zambiri kumagwiritsidwa ntchito pomaliza ndi kumaliza.
Zotopetsa
Boring ndi mtundu wa njira yodulira m'mimba mwake yomwe imagwiritsa ntchito chida kukulitsa dzenje kapena mizere yozungulira.Magwiritsidwe ake nthawi zambiri amachokera ku semi rough Machining mpaka kumaliza.Chida chomwe chimagwiritsidwa ntchito nthawi zambiri chimakhala chida chotopetsa (chotchedwa boring bar).
1) Kulondola kosasangalatsa kwa zida zachitsulo kumatha kufika IT9 ~ IT7, ndipo kuuma kwapansi ndi 2.5 ~ 0.16 μ m.
2) Kulondola kwa makina otopetsa mwatsatanetsatane kumatha kufika IT7 ~ IT6, ndipo kuuma kwapamwamba ndi 0.63 ~ 0.08 μ m.
