1. Sarudza zvichienderana nenzvimbo yekushivirira kwepombi
Mapombi emuchina emumba akanyorwa nekodhi yenzvimbo yekutsungirira yedhayamita yepitch: H1, H2, uye H3 zvichiteerana zvinoratidza nzvimbo dzakasiyana dzenzvimbo yekutsungirira, asi kukosha kwekutsungirira kwakafanana. Kodhi yenzvimbo yekutsungirira yemapombi emaoko iH4, kukosha kwekutsungirira, pitch uye angle kukanganisa zvakakura pane mapombi emuchina, uye zvinhu, kurapwa kwekupisa uye maitiro ekugadzira hazvina kunaka semapombi emuchina.
H4 haifanirwe kunyorwa sezvinodiwa. Magiredhi enzvimbo yemukati yekutsungirira tambo anogona kugadziriswa netap pitch tolerance zone ndeaya anotevera: Kodhi yenzvimbo yekutsungirira tap inoshanda kune magiredhi enzvimbo yekutsungirira tambo yemukati H1 4H, 5H; H2 5G, 6H; H3 6G, 7H, 7G; H4 6H, 7H Mamwe makambani anoshandisa mapombi anowanikwa kunze kwenyika anowanzo nyorwa nevagadziri vekuGerman seISO1 4H; ISO2 6H; ISO3 6G (chiyero chepasi rose ISO1-3 chakaenzana nechiyero chenyika H1-3), saka kodhi yenzvimbo yekutsungirira tap uye nzvimbo yekutsungirira tambo yemukati inogona kugadziriswa zvese zviri zviviri.
Kusarudza mwero weshinda Parizvino kune mwero mitatu yakafanana yeshinda dzakajairika: metric, imperial, uye united (inozivikanwawo seAmerican). Sisitimu yemetric ishinda ine kona yeprofile yemazino ye60 degrees mu millimeters.
2. Sarudza zvichienderana nerudzi rwekudzvanya
Zvatinowanzo shandisa ndeizvi: matepi eflute akatwasuka, matepi eflute anotenderera, matepi espiral point, matepi eextrusion, rimwe nerimwe rine zvarinobatsira.
Mapombi eflute akatwasuka ane simba guru rekushandisa, simbi isina ferrous kana simbi yeferrous inogona kugadziriswa, uye mutengo wayo ndiwo wakachipa. Zvisinei, kukosha kwayo kwakadererawo, zvese zvinogona kuitwa, hapana chakanakisa. Chikamu checoni yekucheka chinogona kuva nemazino maviri, mana, uye matanhatu. Koni pfupi inoshandiswa kune maburi asina through, uye koni refu inoshandiswa kune maburi anopinza. Chero bedzi gomba repasi rakadzika zvakakwana, koni yekucheka inofanira kunge yakareba sezvinobvira, kuitira kuti pave nemazino akawanda anogovana mutoro wekucheka uye hupenyu hwebasa hwakareba.
Mapombi emuchina we spiral flute akakodzera kugadzirisa shinda dzisina kupinda mugomba, uye machipisi anoburitswa kumashure panguva yekugadzirisa. Nekuda kwe helix angle, kona chaiyo yekucheka yepombi ichawedzera nekuwedzera kwe helix angle. Ruzivo rwunotiudza: Pakugadzirisa simbi dzesimbi, helix angle inofanira kunge iri diki, kazhinji inenge madhigirii makumi matatu, kuti ive nechokwadi chekuti mazino e spiral akasimba. Pakugadzirisa simbi dzisina feri, helix angle inofanira kunge yakakura, inogona kunge iri madhigirii makumi mana nemashanu, uye kucheka kunofanira kunge kwakapinza.
Chip inoburitswa mberi kana shinda yacho yagadziriswa ne point tap. Magadzirirwo ayo epakati akakura, simba rayo riri nani, uye inogona kutsungirira masimba makuru ekucheka. Mhedzisiro yekugadzirisa simbi dzisina ferrous, simbi isingasvibi, uye simbi dzine ferrous yakanaka kwazvo, uye matepi e screw-point anofanirwa kushandiswa zvakanyanya kune tambo dzine maburi.
Mapombi ekubvisa simbi akakodzera kugadzirisa simbi dzisina ferrous. Kusiyana nepfungwa yekushanda kwemapombi ekucheka ari pamusoro apa, anoburitsa simbi kuti iite kuti ikanganise uye igadzire shinda dzemukati. Fiber yesimbi yemukati inobviswa inoramba iripo, ine simba guru rekukwenya uye kuchekwa, uye kuomarara kwakanaka pamusoro. Zvisinei, zvinodiwa paburi repasi repombi yekubvisa simbi zvakakwirira: zvakakura kwazvo, uye huwandu hwesimbi yepasi hudiki, zvichikonzera kuti mukati. Dhayamita yeshinda yakakura zvakanyanya uye simba harikwani. Kana iri diki zvakanyanya, simbi yakavharwa uye yakaburitswa haina pekuenda, zvichiita kuti pombi iputsike.
