Mndandanda: Chifukwa Chake Ma Drill Bits Amalephera | Nkhani 10
Mawu Ofunika: ngodya ya drill bit point, 118 vs 135 drill bit, split point drill bit, HSS drill bit, drill bit select guide
Ngati mufufuza mafunso okwanira okhudza kubowola, mumaona kalembedwe. Ogula amafunsa kuti ndi ngodya iti ya "point" yomwe "ili bwino" - 118° kapena 135° - ngati kuti imodzi ndi yokwera kuposa inzake. Sizili choncho. Ngodya iliyonse imathetsa vuto lina, ndipo chisokonezo nthawi zambiri chimachokera ku kopi ya malonda yomwe imawona mfundo yogawanika ya 135° ngati njira yosinthira m'malo mwa chida china cha ntchito inayake.
Timapanga zonse ziwiri, mochuluka, kwa makasitomala omwe amazigwiritsa ntchito m'njira zosiyanasiyana. Apa ndi pomwe zimatsimikiza kuti ndi iti yoyenera mu bokosi la zida la wogula - ndi chifukwa chake.
Kodi Angle ya Point Imasinthadi?
Ngodya ya mfundo ndi ngodya yomwe imapangidwa pakati pa milomo iwiri yodula yomwe ili kumapeto kwa chobowolera. Nthawi zambiri imafotokozedwa kuti "118° ndi yakuthwa, 135° ndi yosalala," zomwe ndi zolondola koma zosakwanira. Zomwe ngodya imeneyo imalamulira ndi zinthu zitatu:
• Kufunika kwa kupondaponda kotani kwa axial kuti muyambe kudula.Mfundo yakuthwa imalimbitsa mphamvu pamalo ang'onoang'ono, kotero imaluma popanda kukankhira pang'ono. Mfundo yosalala imafalitsa katunduyo m'mphepete mwakutali.
• Momwe m'mphepete mwa chisel umagwirira ntchito.Mphepete mwa chisel — gawo lalifupi lomwe lili pakati pa nsonga, pomwe zitoliro ziwiri zimakumana — silidula. Limakankhira zinthu pambali. Ili ndiye gwero lalikulu kwambiri la kukangana ndi kutentha kumayambiriro kwa dzenje, ndipo limachita mosiyana kutengera ngodya ya mfundo.
• Kupanga kwa chips.Pa 118°, makulidwe a chip amasiyana kwambiri m'mphepete mwa njira yosinthira - chokhuthala pakona yakunja, chopyapyala pafupi ndi pakati. Pa 135°, makulidwe a chip ndi ofanana kwambiri, zomwe ndizofunikira pa zipangizo zomwe zimapanga chips zazitali komanso zonga zingwe.
Palibe chilichonse mwa izi chomwe chili maganizo. Ichi ndichifukwa chake pali ma angles awiriwa, ndipo chifukwa chake imodzi si "mtundu wabwino" wa inayo.
Chifukwa Chake 135° Nthawi Zonse Imabwera Ndi Gawo Logawanika
Izi ziyenera kufotokozedwa bwino, chifukwa ndi gawo lomwe malangizo ambiri opezera zinthu amalakwitsa kapena kuphonya kwathunthu.
Mphepete mwa chisel sidula - imatulutsa zinthu. Ngodya yomwe imachita izi (ngodya yake yogwira ntchito ya rake) imakhala yoipa kwambiri pamene ngodya ya mfundo ikukhala yosalala. Mwachidule: mfundo ikasalala, gawo lapakati limakhala lolimba kwambiri m'malo modula. Mfundo ya 135°, ngati siigwiritsidwa ntchito, imakhala ndi vuto lalikulu la m'mphepete mwa chisel kuposa mfundo ya 118° - osati yocheperako.
Zimenezo n’zosiyana ndi zimene ogula ambiri amaganiza. Mfundo yake ndi yakuti: "135° ndi yosalala, flatter iyenera kutanthauza yofatsa, yofatsa iyenera kutanthauza yosavuta kuyamba." Ndipotu, mfundo yosagawanika ya 135° imapita patsogolo kuposa mfundo yokhazikika ya 118°, chifukwa mawonekedwe omwe akuyenera kuti apangitse kuti ikhale yokhazikika m'mphepete mwakunja amachititsa kuti pakati pakhale poyipa kwambiri.
Ma geometry a ma point split point alipo makamaka kuti akonze izi. Amaphwanya m'mbali ziwiri zowonjezera zodulira m'mphepete mwa chisel, ndikusandutsa gawo lapakati losadulira kukhala malo enieni odulira. Ndicho chimene chimapangitsa kuti 135° split point ikhale yodziyimira payokha komanso kuti iyambe pansi - osati ngodya ya mfundo yokha.
Ichi ndichifukwa chake ziwirizi nthawi zambiri zimagulitsidwa pamodzi. Mfundo ya 135° yopanda mfundo yogawanika imagwira ntchito bwino kwambiri mu ntchito zomwezo 135° imasankhidwa chifukwa cha — mabowo olondola muzinthu zolimba, ntchito ya CNC yopanda kuponda pakati, kuboola pamalo opindika kapena oterera. Palibe chokwera chomwe chimatsala mukadumpha sitepe ya mfundo yogawanika, kotero opanga ochepa kwambiri amavutika kupereka kuphatikiza kumeneko. Si lamulo lovuta la majimu. Ndi kuti 135° yopanda mfundo yogawanika imawononga cholinga chake.
Lingaliro lolakwika lofala lomwe liyenera kukonzedwa mwachindunji: mfundo yogawanika si yokhazikika pa 135° yokha.Malo ogawanika a 118° alipo ndipo amagwiritsidwa ntchito — makamaka pamene wogula akufuna mphamvu yotsika komanso kusinthasintha kwa ntchito yonse ya 118°, komanso amafunika malo abwino pakati kuposa malo okhazikika a 118°, popanda kusuntha kupita ku malo osalala komanso osawonongeka a 135°. Sizachilendo kwenikweni chifukwa mapulogalamu ambiri a 118° safuna kulondola kwa malo pakati poyamba, koma ndi kasinthidwe kwenikweni, kopangidwa — osati chidwi chapadera.
Ngodya ya Mfundo Si Nkhani Yonse — Khalidwe la Zinthu Zachilengedwe Limasiyana
Kuona ngodya ya mfundo ngati chinthu chimodzi chomwe chimatsimikizira kupambana kwa kubowola kumachepetsa vutoli. Zitsanzo zingapo pomwe lamulo la "zinthu zovuta, ngodya yosalala" silikugwira ntchito:
•Aluminiyamu:Ngodya ya mfundo si yofunika kwambiri pano kuposa ngodya ya helix ndi milomo yopumira. Chobowola chokhala ndi ngodya ya helix yayitali (34°–38°) komanso chopumira cha milomo chochuluka chimachotsa zipsera mwachangu mokwanira kuti chiteteze m'mphepete mwake — njira yeniyeni yolephera mu aluminiyamu — mosasamala kanthu kuti mfundoyo ndi 118° kapena 135°.
•Chitsulo chopangidwa ndi pulasitiki:Amapanga ma chips afupiafupi, osapanga ma granular osati aatali, kotero ubwino wochotsa ma chips a 135° ndi wofunika kwambiri pano kuposa zipangizo zomwe zimapanga ma chips osalekeza. Masitolo ambiri amagwiritsa ntchito 118° pa chitsulo chopangidwa popanda vuto.
•Chitsulo chosapanga dzimbiri:Apa ndi pomwe malo ogawanika a 135° amatchuka. Ntchito yosapanga dzimbiri imalimba ikakanikizidwa, ndipo ntchito yolima ya m'mphepete mwa chisel kumayambiriro kwa dzenje ndiyo imayambitsa kuuma kumeneko. Kuchepetsa kukangana kumeneko pogwiritsa ntchito mawonekedwe ogawanika sikofunikira ngati mukufuna kuti dzenje likhale labwino nthawi zonse.
•Mapulasitiki ndi zinthu zophatikizika:Mfundo zake zimasinthasintha kwathunthu. Zipangizozi zimafunika chopingasa, osati chakuthwa kwambiri, kuti zisasweke kapena kusweka pamene chobowola chikutuluka mu chinthucho. Chitsogozo cha ngodya ya malo obowola zitsulo sichigwira ntchito.
Kachitidwe kameneka kakugwirizana ndi zomwe tawona pa njira iliyonse yolephera mu mndandanda uno: nambala imodzi ya pepala lofotokozera nthawi zambiri simafotokoza nkhani yonse. Ngodya ya mfundo imagwirizana ndi ngodya ya helix, kupumula kwa milomo, ndi makulidwe a ukonde. Kuiona ngati chisankho chokha ndi momwe ogula amathera ndi chobowola chomwe chili cholondola papepala ndi cholakwika pantchitoyo.
Kodi Izi Zikutanthauza Chiyani pa Kupeza Ndalama?
Ngati mukufuna kugwiritsa ntchito zinthu zobowola m'sitolo yopangira zinthu zosiyanasiyana, 118° yogwiritsidwa ntchito nthawi zonse imaphimba ntchito zambiri za tsiku ndi tsiku pamtengo wotsika. Ngati ntchito yanu ikugwiritsidwa ntchito pogwiritsa ntchito chitsulo chosapanga dzimbiri, chitsulo chosungunuka, kapena zinthu zolimba — kapena ngati njira yanu siyilola kuti pakhale sitepe yopunthira pakati — 135° si njira yabwino yopezera, ndikofunika kuti nthawi yozungulira ikhale yofanana.
Ngodya yosindikizidwa pa pepala lofotokozera imakhala yothandiza pokhapokha mutadziwa vuto lomwe likuthetsa. Chidutswa chobowola chomwe chimayenda, kutsetsereka, kapena kutha msanga sikutanthauza kuti ndi chobowola choipa - mwina ndi ngodya yolakwika poyerekeza ndi zomwe mwapemphedwa kuchita.
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.
