Ogula akatifunsa za HSS drill bits, funso limodzi lodziwika bwino ndi lakuti: "Kodi pali kusiyana kotani pakati pa M42, M35, M2 — ndipo bwanji za 4341?
Ndi funso labwino. Zonsezi ndi zipangizo zachitsulo champhamvu kwambiri (HSS), ndipo pamwamba pake, zikuwoneka zofanana kwambiri. Koma mtundu womwe mwasankha umakhudza kwambiri nthawi yomwe drill yanu imatenga, momwe imagwirira ntchito ikatenthedwa, komanso ngati ndi yoyenera zinthu zomwe mukudula.
Nayi njira yosavuta yofotokozera.
Kodi HSS ndi chiyani, ndipo nchifukwa chiyani giredi ndi yofunika?
HSS imayimira High-Speed Steel — chida chopangidwa ndi chitsulo chopangidwa kuti chidulire chitsulo pa liwiro lalikulu popanda kutaya kuuma kwake. Mosiyana ndi chitsulo cha kaboni, HSS imasungabe mphamvu yake yopangira zinthu ngakhale ikatentha kwambiri pobowola.
Koma si HSS yonse yomwe ili yofanana. Giredi — M42, M35, M2, 4341, ndi zina — imatanthauza kapangidwe kake ka alloy. Kusiyana pang'ono kwa zinthu monga tungsten, molybdenum, vanadium, ndi cobalt kumabweretsa kusiyana kwakukulu pakugwira ntchito.
Zindikirani: M42 imagwiritsa ntchito njira yosiyana ndi M35 — imagwiritsa ntchito kuchuluka kwa molybdenum m'malo mwa tungsten yolemera, zomwe zimapangitsa kuti ikhale yolimba kwambiri pamtengo wochepa wa aloyi.
HRC yapamwamba imatanthauza kuti singawonongeke bwino — komanso kuti ikhale yopyapyala pang'ono. M42 ndi yovuta kwambiri, koma imafunika kukhazikika komanso kolimba kuti isagwe. 4341 ndi yofewa komanso yolimba kwambiri, zomwe zimapangitsa kuti ikhale yolekerera nthawi zonse.
M42 — Kalasi Yabwino Kwambiri ya Ma Alloys Ovuta
M42 ili pamwamba pa HSS. Ndi 8% cobalt ndi kuchuluka kwa molybdenum (HS2-9-1-8, yomwe imadziwikanso kuti HSSCo8, SKH59, P2M9K8, kapena S500), idapangidwira zinthu zomwe zingawononge mwachangu chobowolera cha HSS chokhazikika.
Tikukamba za ma aloyi a nickel, titaniyamu, zitsulo zolimba, ma superalloy osatentha — zinthu zomwe ndege, chitetezo, ndi mafakitale apamwamba amadalira. M42 imagwirira ntchito izi chifukwa imatha kupirira kutentha kopitilira 680°C pamene ikusunga m'mphepete mwake wabwino komanso wakuthwa.
Vuto ndilakuti M42 ndi yofooka kwambiri kuposa magiredi omwe ali pansi pake. Imagwira ntchito bwino kwambiri m'malo olimba komanso olamulidwa komwe kugwedezeka kumachepetsedwa. Komanso imakhala ndi mtengo wokwera - koma kuti igwiritsidwe ntchito moyenera, nthawi yayitali ya chidacho imatsimikizira kuti ndi yolondola.
M35 — Mukakumba Zinthu Zolimba
M35 imawonjezera 5% ya cobalt ku maziko a M2 (ndiye chifukwa chake dzina lina ndi HSSCo5 kapena HS6-5-2-5). Kuchuluka kwa cobalt kumeneku kumawonjezera kukana kutentha kwa chobowoleracho — mpaka pafupifupi 630–650°C — ndipo kumakankhira kuuma kufika pa 63–66 HRC.
Kwa ogulitsa omwe amapereka ku mafakitale monga magalimoto, HVAC, kapena opanga zinthu zopepuka — komwe ntchito yachitsulo chosapanga dzimbiri ndi yofala — M35 ndi yosinthika mwanzeru kuposa M2. Ndi yovuta, yosatha, ndipo imapereka moyo wautali wa zida m'mikhalidwe yovuta popanda kufooka kwa M42.
Ganizirani za M35 ngati malo abwino: abwino kwambiri kuposa HSS wamba, koma akadali othandiza komanso odalirika m'malo osiyanasiyana ochitira misonkhano.
M2 — Muyezo Womwe Umagwira Ntchito Zambiri
M2 ndiye mtundu wa HSS womwe umagwiritsidwa ntchito kwambiri padziko lonse lapansi. Dzina lake lonse ndi HS6-5-2 (yomwe imadziwikanso kuti SKH51 kapena P6M5), zomwe zimasonyeza kapangidwe kake: 6% tungsten, 5% molybdenum, 2% vanadium — yopanda cobalt.
Ndi chinthu chofunika kwambiri pobowola zitsulo zosiyanasiyana — chitsulo chofewa, aluminiyamu, mkuwa, chitsulo chosungunuka, ndi zina zambiri. Mabowola a M2 ndi opukutidwa bwino, ogwirizana, komanso otsika mtengo. Pa malo ambiri ogwirira ntchito ndi kupanga, M2 ndiye chomwe mukufuna.
Ngati wogula satchula giredi, M2 nthawi zambiri ndiye yomwe akupeza - ndipo pazinthu zambiri, ndizoyenera.
4341 — Njira Yolimba Komanso Yosiyanasiyana Yolowera Pamlingo Woyenera
4341 (yolembedwanso kuti W4Mo3Cr4VSi) ndi mtundu wa tungsten-molybdenum HSS womwe uli pansi pa M2 pakugwira ntchito, koma umapereka kulimba kwabwino komanso kukana kugwedezeka. Ndi wotchuka kwambiri m'misika komwe kugwiritsa ntchito bwino ndalama ndikofunikira kwambiri.
Poyerekeza ndi M2, 4341 ili ndi kuuma kochepa komanso kuuma kotentha kochepa - zomwe zikutanthauza kuti siigwira bwino kutentha kwambiri. Koma pobowola zitsulo zofewa kapena m'malo omwe ma drill nthawi zambiri amasinthidwa m'malo mokonzedwa, imagwira ntchito moyenera komanso mopanda ndalama.
4341 ndi njira yodziwika bwino yogwiritsira ntchito ma bit drill bit omwe amagulitsidwa kudzera m'masitolo ogulitsa ndi zida zamagetsi, komwe mtengo wake ndi wofunika kwambiri kuposa magwiridwe antchito apamwamba. Si chida chabwino kwambiri cha ma alloys olimba — koma pa ntchito yopepuka ya tsiku ndi tsiku, imapeza malo ake.

Zimene Timapereka ku Jiacheng Tools
Ku Jiacheng Tools, timapanga ma drill bits m'ma grade onse anayi — M42, M35, M2, ndi 4341. Zonsezi zimapezeka ngati zinthu zopangidwa ndi OEM/private label, ndipo timagwira ntchito ndi ogulitsa padziko lonse lapansi kuti tigwirizane ndi grade yoyenera pamsika wawo.
Ngati simukudziwa kuti ndi giredi iti yoyenera ogula anu, gulu lathu limasangalala kukupatsani upangiri kutengera pulogalamu yomaliza. Nthawi zambiri, kukambirana mwachidule za zinthu zomwe makasitomala anu akufufuza kungapangitse kusiyana kwakukulu pakugwira ntchito kwa malonda - komanso m'maoda obwerezabwereza.
