Mndandanda: Chifukwa Chake Ma Drill Bits Amalephera | Nkhani 5
Mawu Ofunika: Ubwino wa HSS drill bit, kulemera kwa drill bit, kuuma kwa drill bit, kuchuluka kwa HSS, kuyang'anira khalidwe la drill bit, momwe mungayesere drill bits
Ogula ambiri omwe amayesa ubwino wa chobowola amafunsa funso losavuta: "Kodi kuuma kwake ndi kotani?"
Si funso lolakwika. Kuuma ndi chimodzi mwa zizindikiro zofunika kwambiri za khalidwe la HSS drill bit. Koma "chovuta nthawi zonse chimakhala chabwino" ndi kusamvetsetsana kofala - ndipo ndi kusamvetsetsana komwe kungapangitse ogula kusankha chinthu cholakwika.
Kodi Kuuma Kumakuuzani Chiyani?
Kuuma, komwe nthawi zambiri kumayesedwa pa sikelo ya Rockwell C (HRC), kumasonyeza momwe m'mphepete mwake umagonjetsera kusintha kwa kutentha pambuyo pothandizidwa ndi kutentha. Pa ma HSS drill bits, nambala iyi imagwirizana mwachindunji ndi ngati m'mphepete mwake umakhalabe wakuthwa komanso wosagwirizana ndi kuwonongeka panthawi yodula.
Kuchiza ndi kutentha ndi komwe kumatsimikizira kuuma. Mwachitsanzo, chitsulo chofananacho - M2 kapena M35 - chingathe kukhala ndi kuuma kosiyana kwambiri kutengera momwe chimachitidwira kutentha. Ichi ndichifukwa chake chitsulo chokha sichingakuuzeni mtundu weniweni wa chobowolera chomalizidwa. Zipangizo ndiye poyambira. Kuchiza ndi kutentha ndi sitepe yomwe imasintha kuthekera kumeneko kukhala magwiridwe antchito enieni.
Chifukwa Chake Kuuma Kwambiri Sikuli Bwino Nthawi Zonse
Apa pali gawo lotsutsana: kukankhira kuuma kwambiri kungapangitse kuti chobowola chilephereke mosavuta.
Kuyerekeza kosavuta kumathandiza kufotokoza chifukwa chake. Chofufutira cha rabara ndi chofewa - chimawonongeka chikapanikizika ndipo sichingathe kusunga mawonekedwe ake. Mbale ya ceramic ndi yolimba - koma ilibe mphamvu yolimba, kotero mphamvu imodzi yokha kapena yopindika imatha kuiphwanya nthawi yomweyo. Chobowola cha HSS chiyenera kukhala pakati pa zinthu ziwirizi: cholimba mokwanira kuti chisawonongeke, koma cholimba mokwanira kuti chizimitse kugwedezeka ndi kugwedezeka kwa zinthu zenizeni popanda kusweka ikangokumana ndi malo olimba muzinthuzo.
Ichi ndichifukwa chake cholinga cha kutentha sichikhala "cholimba momwe zingathere." Cholinga chenicheni ndikupeza kulimba koyenera kwa chitsulocho ndikugwiritsa ntchito. Chobowola cholimba kwambiri koma chosakwanira chingalephereke mwachangu kuposa chomwe chili ndi kulimba kochepa komanso kulimba koyenera - ndipo nthawi zambiri chimalephera chifukwa cha kuduladula kapena kusweka, osati chifukwa cha kuwonongeka pang'onopang'ono.
Chifukwa Chake Kuuma Ndi Mtundu, Osati Nambala Yokha
Ogula nthawi zambiri amafuna chiŵerengero chimodzi cholondola cha kuuma — mwachitsanzo “HRC 65.” M'malo mwake, kuuma nthawi zonse kumakhala pamlingo winawake, osati mtengo umodzi wokhazikika.
Izi zili choncho chifukwa kutentha kumakhala ndi njira zosiyanasiyana zachilengedwe. Ngakhale mkati mwa ng'anjo yomweyi komanso kupanga komweko, kuuma kumasiyana pang'ono kuchokera pa chidutswa chimodzi kupita pa chidutswa. Izi ndi zachilendo m'makampani onse — sizili za fakitale imodzi yokha. Ngati wogulitsa akutchula nambala imodzi yeniyeni ndipo akunena kuti chidutswa chilichonse chikugwirizana nayo ndendende, mfundo imeneyo ndiyofunika kuiganizira.
Deta yodalirika komanso yowona mtima yolimba iyenera kuperekedwa ngati mtunda, yothandizidwa ndi muyeso weniweni - osati nambala yokumbukiridwa. Posachedwapa tasintha njira yathu yochizira kutentha, ndipo mtunda wathu woyesedwa wa kulimba ndi pafupifupi HRC 64–67 wa M2 ndi HRC 65–69 wa M35 cobalt. Izi ndi mtunda womwe umasonyeza kusiyana kwabwinobwino kwa batch-to-batch, osati lonjezo lakuti chidutswa chilichonse chimagwera pa chifaniziro chimodzi chenicheni.
Chimachitika ndi Chiyani Ngati Kuuma Kuli Kochepa Kapena Kosafanana?
Ngati chithandizo cha kutentha sichikulamulidwa bwino, zotsatira zake zimakhala monga:
• Kulimba kosakwanira: m'mphepete mwake umafewa msanga panthawi yodula, kuwonongeka kumafulumira, ndipo nthawi yogwiritsira ntchito zida imafupikitsidwa.
• Kulimba kosafanana: mfundo zina pa chobowolera chimodzi zimakhala zofewa kapena zolimba kuposa zina, zomwe zimapangitsa kuti zisawonongeke bwino — kapena zimapangitsa kuti kulimbako kusinthe mwadzidzidzi, zomwe nthawi zambiri zimakhala poyambira kusweka.
• Kusiyanasiyana kwakukulu kwa batch-to-batch: ngakhale kuuma kwapakati kuli kovomerezeka, kusiyana kwakukulu mkati mwa batch kumatanthauza kuti ogula amakumana ndi "batch iyi idagwira ntchito bwino, yotsatira sinagwire ntchito." Kusasinthasintha koteroko nthawi zambiri kumakhala kovuta kuyendetsa pokonzekera kupanga kuposa batch imodzi yokha yomwe ikulephera kukwaniritsa zofunikira.
Palibe chilichonse mwa izi chomwe chimawoneka kuchokera kunja. Mtundu, mawonekedwe ake, ndi momwe zimamvekera sizikutsimikizirani chilichonse chodalirika chokhudza kuuma kwenikweni - mfundo yomweyi yomwe tidakambirana m'nkhani yathu yoyambirira yokhudza chifukwa chake kulemera sikungadziwike mtundu wa HSS. Kuweruza kowoneka bwino komanso kogwira mtima sikoyenera m'malo mwa kuyeza.
Momwe Ogula Angatsimikizire Kuuma
Kuuma ndi chimodzi mwa zizindikiro zochepa za khalidwe zomwe zingayesedwe mwachindunji m'malo moweruzidwa ndi zomwe zachitika zokha. Tikukulimbikitsani ogula:
• Funsani wogulitsa za kuuma kwa chitsulo chomwe chimagwiritsidwa ntchito popanga zinthu zobowolera.
• Pa maoda ofunikira, pemphani wogulitsa kuti ayesere kuuma pamalopo pogwiritsa ntchito choyezera kuuma cha Rockwell panthawi yopanga, kapena gwiritsani ntchito choyezera chanu cha Rockwell kuti muwone zitsanzo zomwe zikubwera - iyi ndi njira yothandiza yotsimikizira yomwe makampani ambiri angakwanitse.
• Samalani osati nambala yolimba yokha, komanso ngati nambalayo yaperekedwa ngati mzere woyezedwa ndi deta yeniyeni kumbuyo kwake, osati chithunzi chogwidwa kuchokera m'maganizo.
Zokhudza mndandanda uwu
Chifukwa Chake Drill Bits Fail ndi mndandanda waukadaulo wolembedwa ndi gulu lathu lopanga. Nkhani iliyonse imayang'ana kwambiri chinthu chimodzi chomwe chimagwira ntchito bwino pa drill bit - kuyambira pazinthu zopangira mpaka kulongedza. Cholinga chake ndi chosavuta: kuthandiza ogula kumvetsetsa zomwe akugula, komanso mafunso oti afunse.
