Mndandanda: Chifukwa Chake Ma Drill Bits Amalephera | Nkhani 11
Mawu Ofunika: kapangidwe ka chitoliro cha drill bit, kuchotsedwa kwa chip, ngodya ya drill bit helix, chitoliro cha parabolic flute bit, makulidwe a ukonde, kulongedza chip, kuboola dzenje lakuya HSS, chitoliro chokhazikika vs chitoliro cha parabolic
Nkhani yomaliza mu mndandanda uno inayang'ana momwe ngodya ya mfundo imagwirizanirana ndi zipangizo zosiyanasiyana - nthawi yomwe m'mphepete mwachitsulo umadula zinthu kuchokera pa workpiece. Iyi imayamba kugwira ntchito nthawi yomweyo: chip ikadulidwa, iyenerabe kuchoka pa dzenjelo. Ngati sichoncho, chilichonse chomwe chili pamwamba - mtundu wa zinthu, kutentha, mawonekedwe a mfundo - chimasiya kugwira ntchito. Kachidutswa kakang'ono kangathe kupangidwa kuchokera ku M35 yeniyeni ndikusenda mpaka ku buku lophunzirira mfundo yogawanika ya 135° ndikulepherabe, ngati chitoliro sichingathe kutulutsa chip mwachangu mokwanira.
Kumene Chip Imapitadi
Chobowolera chopotoka chimachotsa zinthu zomwe zili kumapeto, koma chimachotsa zinthuzo m'mphepete mwa chitoliro — njira yozungulira yomwe imazungulira kuchokera m'mphepete mwa chodulira kubwerera ku shank. Chip sichimatuluka m'dzenje lokha; chimakwera m'mphepete mwa chitolirocho, chikukankhidwa ndi kuzungulira kwa chidutswacho ndi mawonekedwe a khoma la chitoliro. Zinthu zitatu zimasankha momwe ulendowo umayendera bwino: momwe chozunguliracho chilili cholimba (ngodya ya helix), kuchuluka kwa chitsulo cholimba chomwe chili pakati pa chidutswacho (kukhuthala kwa ukonde), ndi kuchuluka kwa malo otseguka omwe chitoliro cha chitoliro chimapereka (mawonekedwe a chitoliro). Palibe chilichonse mwa izi chomwe chingakonzedwe chokha — chimagulitsidwa motsutsana, ndipo kulinganiza koyenera kumadalira zinthuzo ndi kuya kwa dzenjelo, osati pa nambala imodzi "yabwino".
Helix Angle: Liwiro Lothawira Kunja Polimbana ndi Mphamvu Yapakati
Ngodya ya Helix ndi ngodya yozungulira ya chitoliro yomwe imayesedwa motsutsana ndi mzere wa chobowolera. Helix yolimba imakankhira zipsu mwachangu ndikufupikitsa kutalika kwa m'mphepete mwa chobowolera nthawi iliyonse - komanso imawonjezera kugwedezeka kwa axial ndikuchotsa zinthu zambiri kuchokera ku thupi la chobowolera, zomwe zimafooketsa pakati. Helix yocheperako imasunga zitsulo zambiri mkati mwa core ndikuyimirira bwino pansi pa torque, koma zipsu zimatuluka pang'onopang'ono, zomwe zimakhala zoletsa kwambiri dzenje likayamba kuya.
Ichi ndichifukwa chake ngodya ya helix imafanana ndi mtundu wa chip m'malo mokhazikika pa nambala imodzi. Ma chips aatali, opindika - mtundu wopangidwa ndi zinthu zofewa kapena zogwira ntchito kwambiri - amafunikira helix yolimba kuti azisunthire; ma chips afupiafupi, osalimba ochokera kuzinthu zolimba safuna kukankhidwa kofanana ndipo amapindula kwambiri ndi mphamvu yowonjezera ya ngodya yosaya kwambiri. Palibe ngodya ya helix "yabwino kwambiri" padziko lonse lapansi. Pali ngodya yokhayo yomwe ikugwirizana ndi momwe chip imapangikira.
Kukhuthala kwa intaneti: Kulimba motsutsana ndi Chip Room
Ukonde ndi pakati pa chitsulo cholimba chomwe chikuyenda pakati pa chitsulocho, pakati pa zitoliro ziwiri. Chimapatsa chitsulocho mphamvu yozungulira — mphamvu yolimbana ndi kupotoka kapena kusweka pansi pa torque yodula. Kukhuthala kwa ukonde sikofanana motsatira chitsulocho; chimachepetsedwa mwadala, chimakhala chocheperako kumapeto komanso chokulirapo kupita ku shank, kotero chitsulocho chimakhala cholimba pomwe torque yosonkhanitsidwa ili yayikulu.
Kusinthana kumeneku ndi kwachindunji: ukonde wambiri umatanthauza mphamvu zambiri, koma malo ochepa mu chitoliro kuti ma chips akhalepo akamatuluka. Kankhirani ukonde kwambiri ndipo ubalewo umatha - ukonde ukadutsa pafupifupi 40% ya kukula kwa chitoliro, njira yotsala ya chitoliro imakhala yopapatiza kwambiri kuti ma chips achotsedwe bwino, ndipo chiopsezo chimasintha kuchoka pa "chidutswacho chimatha" kupita ku "kusweka kwa ma bit." Tsatanetsatane uwu nthawi zambiri sungawonekere pa pepala la spec, koma ndi chimodzi mwa zifukwa zomwe zimadziwika kwambiri kuti chitoliro chimasweka mkati mwa dzenje m'malo mofooka kumapeto.
Chitoliro Chokhazikika ndi Chitoliro Chamatsenga: Mayankho Awiri a Vuto Lomwelo
Timapanga mitundu yonse iwiri ya chitoliro, ndipo si mtundu "woyambira" komanso "wosinthidwa" wa chitoliro chomwecho - amapangidwa kuti agwire ntchito zosiyanasiyana.
Chitoliro chokhazikika chimasunga njira yopapatiza komanso ukonde wopepuka, zomwe zimakwanira kuboola zinthu zambiri: kuya kwa dzenje losaya kwambiri mpaka pakati, ntchito yokhazikika yogwira ntchito, ndi zipangizo zomwe sizipanga tchipisi tatali komanso tosatheka kusamalidwa. Kuboola kwa tsiku ndi tsiku kumagwera m'gulu ili, ndipo palibe phindu lochita zinthu mopitirira muyeso kupatula pamenepo.
Chitoliro cha parabolic chimatsegula ngalandeyo. Khoma la chitoliro limaphwanyidwa kukhala malo okulirapo, opindika omwe amapatsa tchipisi malo ambiri komanso njira yosalala yotulukira, pamodzi ndi chozungulira chofulumira chomwe chimawasuntha mwamphamvu kwambiri. Njira yayikulu imatanthauza kuti ukonde womwe uli pansi pake ukhozanso kukulitsidwa - pafupifupi 25-50% ya mulifupi wa kubowola, poyerekeza ndi pafupifupi 12-25% pa chitoliro chokhazikika - kotero chidutswacho chimapeza mphamvu ya chip ndi mphamvu yapakati nthawi yomweyo, m'malo mosinthana chimodzi ndi china. Kuphatikiza kumeneko ndiko komwe kumalola chitoliro cha parabolic kugwira m'mabowo akuya komanso m'zinthu zomwe zimapanga tchipisi tatali komanso topitirira, kuphatikiza chitsulo chosapanga dzimbiri, mkuwa, ndi aluminiyamu, popanda kufunikira kubowola dzenje nthawi zambiri.
Ukonde wokhuthala umenewo umakweza mphamvu ya axial, ndichifukwa chake ma parabolic flute drills nthawi zambiri amagwirizanitsidwa ndi malo ogawanika - mawonekedwe omwewo a 135° omwe afotokozedwa mu Nkhani 9 - kuti abweretse mphamvuyo pamlingo wosavuta kugwiritsa ntchito.
Mu mzere wathu wa parabolic, timaperekanso mipata iwiri yolumikizira. V-groove yayikulu imakulitsa chipinda cha chip ndi liwiro lothawirako, zomwe zimagwirizana ndi zipangizo zovuta kugwiritsa ntchito makina koma zimabwera ndi chitsulo chochepa kumbuyo kwake. V-groove yaying'ono imasunga chitsulo chochuluka m'thupi kuti chigwire ntchito pomwe kulimba ndikofunikira kuposa kuchuluka kwa flute. Choti mugwiritse ntchito chimadalira ngati kulimba kwa chinthucho kapena workpiece ndiye chinthu choletsa - osati chomwe chikumveka chotsogola kwambiri.
Kodi Chimachitika N'chiyani Chitoliro Chikataya Mkangano?
Ngati mawonekedwe a chitoliro sakugwirizana ndi zinthu kapena kuya kwa dzenje, chitolirocho chimasiya kuyenda chisanafike pamwamba pa chitoliro. Chimalowa mu ngalande m'malo motuluka. Kuchokera pamenepo, kulephera kumakhala kofanana: zitoliro zopakidwa zimawonjezera kukangana motsutsana ndi khoma la chitoliro ndi khoma la dzenje, kukangana kumapanga kutentha mwachangu kuposa momwe kungathere, ndipo m'mphepete mwachitsulocho mumayamba kudulanso zinthu zomwe zachotsedwa kale m'malo mwa zatsopano. Zotsatira zake zomwe zimawoneka ndi bore yolimba kapena yayikulu, kukwera mwadzidzidzi kwa torque, ndipo - ngati kulongedza kuli kokwanira - pang'ono komwe kumayima ndikugwa mkati mwa dzenjelo.
Umu ndi momwe mndandanda uwu umabwereranso: wogula sakugula kwenikweni chobowolera, akugula luso lopanga mabowo nthawi zonse. Kapangidwe ka chitoliro ndi malo olephera omwe ndi osavuta kunyalanyaza chifukwa chitoliro chokhazikika ndi chitoliro cha parabolic zimafanana pachithunzi. Kusiyanako kumawonekera kokha dzenje likazama mokwanira, kapena zinthuzo zimapanga zidutswa zazitali kwambiri kuti ngalande yopapatiza isagwire.
Kodi Izi Zikutanthauza Chiyani Poyerekeza Ogulitsa?
Palibe chilichonse mwa izi chomwe chikunena za chitoliro chomwe chili "chabwino." Ndi za chitoliro chomwe chapangidwira ntchito yomwe ili patsogolo panu. Poyesa chobowolera pogwiritsa ntchito chida chanu chenicheni, ndikofunikira kufunsa kuti:
•Kodi dzenje lomwe mukufuna kuliika ndi lotani, ndipo kodi chitolirocho chili ndi njira yokwanira yotsegulira kuti chichotse ming'alu pa kuya kumeneko popanda kugogoda pafupipafupi?
•Kodi makulidwe a ukonde amafanana ndi zinthuzo — mphamvu yokwanira yapakati popanda kudzaza njira ya chip?
•Ngati wogulitsayo akupereka chitoliro cha parabolic, kodi chimagwirizanitsidwa ndi malo ogawanika kuti azitha kuyendetsa bwino mphamvu yowonjezera, kapena kodi tsatanetsataneyo unasiyidwa?
Mafunso awa ndi omwe amakuuzani ngati chitoliro chinapangidwira zinthu zanu ndi kuya kwa dzenje, kapena chinangolembedwa kuti chigwiritsidwe ntchito.
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.
