Iyo injeniyeri n'abaguzi bagennye imyitozo yo hagati ya DIN 333, kimwe mu bibazo dukunze guhura nabyo ni iki: "Ni irihe tandukaniro riri hagati y'ubwoko bwa A n'ubwoko bwa B - kandi ni irihe nkeneye mu by'ukuri?"
Ni ikibazo cyumvikana. Ubwo bwoko bwombi bufite inguni imwe ya chamfer ya 60°, bukurikiza urugero rumwe rwa DIN 333, kandi buboneka mu bikoresho bimwe. Ariko hari itandukaniro rikomeye hagati yabyo - rigira ingaruka ku buryo umwobo wo hagati ugumana neza mu gihe cyo gukora imashini.
Iyi mfashanyigisho isobanura neza itandukaniro, hamwe n'imbonerahamwe za DIN 333 ku bwoko bwombi.
DIN 333 Center Drill ni iki?
Imashini yo gucukura hagati - yitwa kandi imashini ivanze n'imashini icukura hagati - ikoreshwa mu gukora umwobo ufite imiterere ya dogere 60 ku mpera y'igikoresho mbere yo guhindukira hagati y'aho ukorera hakoreshejwe imashini. Umwobo wo hagati utanga ahantu hahamye ho kwicara hagati y'imashini, bigatuma igice cyo hagati gifata neza kandi gitunganye mu gihe cyose cyo gucura, gusya, cyangwa gusya.
DIN 333 ni igipimo cy’Abadage (Deutsches Institut für Normung) kigenga imiterere, ingano, n’ubushobozi bwo kwihanganira imyitozo yo hagati ya 60°. Gisobanura ubwoko butatu: Ubwoko bwa A, Ubwoko bwa B, n’ubwoko bwa R. Iyi ngingo yibanda ku bwoko bubiri bukunze kugaragazwa: A na B.

Amahitamo y'ibikoresho: M2 vs. M35
Imyitozo yo hagati yo mu bwoko bwa A na B iboneka mu byiciro bibiri bya HSS. Amahitamo y'ibikoresho ntaho ahuriye n'ubwoko bwabyo - biterwa n'ibikoresho byo gukora n'ingano y'umusaruro.
M2 HSS — Icyiciro Gisanzwe
M2 (HS6-5-2) ni yo mashini ya HSS ikoreshwa cyane ku isi. Itanga ubukomere bwiza, idashobora kwangirika neza, kandi ikora neza mu bikoresho bitandukanye - icyuma cyoroshye, aluminiyumu, icyuma gishongeshejwe, umuringa, n'ibindi byuma byinshi bidakoresha feri. Imashini zo hagati za M2 ni zo zikoreshwa cyane mu gutunganya ibyuma.
M35 HSS-Co — Igipimo cya Cobalt ku busabe busaba akazi kenshi
M35 (HS6-5-2-5, izwi kandi nka HSSCo5) yongera 5% bya kobalti ku rufatiro rwa M2. Ibi byongera ubushobozi bwo kwirinda ubushyuhe kuri dogere selisiyusi 630–650 kandi byongera ubukana bwa dogere selisiyusi 63–66. M35 ni yo ikoreshwa cyane iyo ishyizwe hagati mu byuma bitagira umugese, ibyuma bikozwe mu cyuma, cyangwa ibindi bikoresho bigoye gukoresha, cyangwa mu gukora ibikoresho byinshi aho igihe cyo gukoresha ibikoresho ari cyo cy'ingenzi.
Amahitamo yo kurangiza ubuso
Uburyo bwo guhitamo: Inzira yo gufata ibyemezo ifatika
Niba urimo gushyira hagati ku gikoresho kizahita gihindurwa muri gahunda imwe, Ubwoko bwa A ni bwo buryo bwiza. Byoroshye, ni bugufi gato, kandi bukoresha inyinshi mu porogaramu zisanzwe zo gushyira hagati ku cyuma.
Niba inzira yawe ikubiyemo kimwe muri ibi bikurikira, garagaza ubwoko bwa B:
• Igikoresho kigenda hagati y'imashini cyangwa kigenda gihinduka hagati y'ibikorwa
• Ibice bibikwa cyangwa bigafatwa nyuma yo kubishyiraho hagati na mbere yo kubihindura burundu
• Ubushobozi bwawe bwo kwihanganira ibintu busaba imiterere ihoraho kandi isubiramo y'umwobo wo hagati mu gihe cyose cyo gukora
• Urimo gukorana n'imirongo ikora neza aho amazi ava mu mwobo wo hagati yangiritse atemerewe
Iyo ushidikanya, ubwoko bwa B ni bwo buryo bwizewe bwo kwirinda. Ingufu z'inyongera zo kurinda ntabwo zongerera ubukana akazi ko gucukura ubwabyo - zituma gusa intebe ziguma uko zari zimeze.
Ibyo Jiacheng Tools itanga
Muri Jiacheng Tools, dukora imyitozo yo hagati ya DIN 333 mu bwoko bwa A na B, iboneka mu bikoresho bya M2 na M35 bifite irangi rya TiN cyangwa TiN. Imyitozo yose yo hagati yuzuye 100% uhereye ku gikoresho gikomeye, ifite ubushobozi bwo kwihanganira umubiri h7, mu murambararo w’umupilote kuva kuri 1.00mm kugeza 12.50mm (Ubwoko bwa A) na 1.00mm kugeza 6.30mm (Ubwoko bwa B).
Isosiyete y'ubucuruzi bw'ibicuruzwa n'ibirango byigenga birahari. Dukorana n'abacuruza ibicuruzwa ku isi hose mu bijyanye n'imodoka, iby'indege, ubwubatsi rusange, n'ibikoresho. Niba ukeneye kwemeza ibisobanuro, gusaba icyitegererezo, cyangwa kuganira ku ngano yihariye, hamagara itsinda ryacu kurijoeyzhu@jiachengtoolsco.comcyangwa gusurawww.jiachengtoolsco.com.
