Kusankha Njere Zabwino Kwambiri Zonyezimira ndi Zopaka |makono makina msonkhano

Mawonekedwe a particles a superabrasive ndi mapangidwe a ❖ kuyanika amathandizira kwambiri pakuyenera kwa mawilo akupera kwa ntchito zosiyanasiyana.
Kufananiza pulogalamuyo ndi gudumu labwino kwambiri la superabrasive kungapindule ndikuwongolera gawo limodzi ndi zokolola, kupanga chidziwitso chozama cha grit, ma bond ndi zokutira zofunika kwambiri kwa ogwiritsa ntchito chopukusira.Chithunzi mwachilolezo cha Wanyu Abrasives.

Kusankha koyenera kwa mawilo apamwamba kwambiri opera ndikofunika kuti pakhale njira yabwino yopera.Gudumu lakumanja limatha kukhathamiritsa magawo pa ola limodzi, kuchepetsa kusintha kwa zida, kukulitsa nthawi yamakina, kukonza zinthu zabwino ndikuchepetsa ndalama zogwirira ntchito.Komabe, kupeza gudumu lotere kumafuna kuphunzira mosamalitsa mawonekedwe ambewu ndi zokutira za superabrasive, pakati pamikhalidwe ina.
Superabrasive mawilo akupera ntchito pansi mikhalidwe akupera kwambiri ndipo ayenera kukhala angapo katundu, kuphatikizapo kuuma pa kutentha, mkulu matenthedwe madutsidwe kuchotsa kutentha m'mphepete, kukhazikika zikuchokera, kuvala kukana, lubricity ndi kukana mapindikidwe pulasitiki.
Mayendedwe a gudumu lopukutira la superabrasive makamaka amatsimikiziridwa ndi gawo lapansi lomangika, komanso mawonekedwe achilengedwe komanso mtundu wanjere yopumira ya gudumu, kaya diamondi kapena kiyubiki boron nitride (CBN).Tinthu tating'onoting'ono ndi zokutira zimapereka mphamvu zosiyanasiyana ndipo motero ndizoyenera kugwiritsa ntchito zosiyanasiyana.Kudziwa kuti ndi tinthu ting'onoting'ono ndi zokutira zomwe zili zabwino kwambiri pazogwiritsa ntchito zitha kupulumutsa opanga ndalama pakapita nthawi.
Kutengera ndi kagwiritsidwe ntchito kapena kagayidwe kake, chimanga chamtengo wapatali kapena chimanga chokwera mtengo chingakhale chopanda ndalama zambiri pantchitoyo.Momwemonso, mawilo okwera mtengo kwambiri a diamondi kapena CBN sangakhale oyenera kugwiritsa ntchito.Chofunika si mtengo, koma mawonekedwe a njere za superabrasive ndi mtundu wa zokutira zomwe zimagwiritsidwa ntchito pa gudumu.
Kulimba kumatanthawuza khalidwe la njere yopweteka pansi pa kupsinjika kwa makina, ndiko kuti, mphamvu yake yokana kusweka, kuswa, ndi kuthyoka.Kukhwinyata kumatanthawuza kutha kwa njere kuswa ndi kudzinola.
Njere zolimba zolimba kwambiri zimakhala zolimba ndipo zimasunga mawonekedwe ake bwino kuposa momwe zimachotsera zinthu.Tinthu tating'onoting'ono timakhala tikuthwa nthawi ndi nthawi, mawonekedwe awo aang'ono amachotsa zinthu zambiri ndikudutsa kulikonse.Ntchito zosiyanasiyana zimafunikira mbewu pamalo osiyanasiyana pamitundu iwiriyi.
Pankhani ya mawonekedwe, pali magulu awiri a polar: blocky ndi angular.The kwambiri agglomerated kapena kuzungulira abrasive particles, sagwira ntchito kudula, koma bwino mawonekedwe anapitiriza.Tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono timakhala tolimba ndipo timalimbana ndi mphamvu zowononga kwambiri musanathyole.
Mosiyana ndi izi, mawonekedwe aang'ono amakhala aukali komanso amaloŵa bwino ndikuchotsa zinthu.Komabe, mbewu za angular zimawonongeka ndi khama lochepa.
Momwemo, payenera kukhala tinthu tating'onoting'ono tomwe timalinganiza mawonekedwe awiriwa, kulola kuti likhale lolimba, kulola kuti liwonongeke mwachibadwa, kuwulula nsonga yatsopano, yakuthwa.Popanda kutha kusweka, njerezo zimaziziritsa ndikuzipaka pa workpiece m'malo modula, zomwe zimapangitsa kuti pakhale mphamvu yogaya komanso mavuto akulu pa gudumu ndi workpiece.
Kupaka ndi njira yophikira kwathunthu komanso mofananamo mbewu za superabrasive ndi wosanjikiza wa zinthu zina.Izi zimawonjezera kukula kwa tirigu ndi kulemera kwake, zomwe nthawi zambiri zimagwiritsidwa ntchito kupititsa patsogolo makhalidwe monga mphamvu ndi kulimba pakupera.
Mphamvu ya matrix omangika kuti igwire njere yonyezimira imatsimikizira kugwira ntchito kwa gudumu lopera.Ubwino waukulu wa zokutira ndikuti amatha kupanga tinthu tating'ono ta diamondi kapena CBN kuti azitsatira bwino gudumu, kaya ndi utomoni, vitreous, chitsulo, wosakanizidwa kapena zina.Kusungidwa bwino kwamakina ndi mankhwala a dongosolo lolumikizirana kumawonjezera kukhulupirika kwa magudumu.
Kupulumutsa mtengo ndi zokolola zambiri zomwe zimabwera ndi kusankha gudumu logaya loyenera zitha kukhala mwayi wampikisano ngati msonkhanowo umasewera makhadi ake moyenera.
Nickel, zokutira zamkuwa ndi siliva ndizovala zodziwika bwino kwambiri.Kuyika kwa nickel kumakhala kofala pamawilo opangidwa ndi utomoni.Zovala izi zimakweza moyo wama gudumu, kutha kwa pamwamba, kutayika kwa kutentha komanso kumamatira kumakina kumalo omangirira kuti mugwire bwino ntchito.
Zophimba zamkuwa ndizomwe zimapangidwira pogaya zowuma chifukwa cha kuthekera kwa mkuwa kuchititsa kutentha kutali ndi malo okupera ndikuwongolera kusungidwa kwa tinthu tating'onoting'ono zamakina ndi mankhwala mu dongosolo lomangika.

Zovala za siliva ndizokwera mtengo kwambiri koma zimapereka kutentha kwapamwamba kwambiri kwa mitundu itatu yokutira, komanso kusungidwa bwino kwa tinthu ndi mafuta owonjezera.Siliva ndiye kumaliza komwe kumakonda kwambiri ngati mafuta abwino amagwiritsidwa ntchito ngati choziziritsa.
Kuchuluka kwa zokutira pa njere za abrasive kungakhale kuchokera ku 30% mpaka 70% ya kulemera konse kwa njere zokutira.Zovala pa tinthu ta diamondi nthawi zambiri zimakhala 50% mpaka 56% polemera, pomwe tinthu tating'onoting'ono ta CBN nthawi zambiri amagwiritsidwa ntchito popaka 60% kulemera kwake.Ma superabrasives okutidwa amakhala okwera mtengo kuposa ma abrasives osakutidwa chifukwa cha magwiridwe antchito apamwamba komanso njira zowonjezera zopangira zomwe zimafunikira kuti apange.
Ngakhale kusintha kwazing'ono kwa abrasive mu gudumu lopera kungakhale kosintha masewera anu akupera ndi ndondomeko.Kupulumutsa mtengo ndi zopindulitsa posankha gudumu logaya loyenera zitha kukhala mwayi wampikisano ngati msonkhanowo umasewera bwino makhadi ake.
Pogwiritsa ntchito njira zotsogola, zapamwamba kwambiri za mphero mu pulogalamu yopangira makina, ukadaulo wa SolidCAM iMachining ukhoza kuchepetsa nthawi yozungulira ndikuwonjezera kwambiri moyo wa zida poyerekeza ndi mphero yachikhalidwe.
Mphamvu zomwe zimakhudzidwa ndi mphero zimatha kuwerengedwa, kulola zida zamasamu kuti zigwiritsidwe ntchito kulosera ndikuwongolera mphamvuzi.Mafomu olondola owerengera mphamvuzi amakupatsani mwayi wowongolera bwino ntchito yamphero.
