Othandizana nawo atatuwa adathandizira zochitika zawo zosiyanasiyana zopanga ndi kukonza komanso zoyambira zawo zomaliza kuti apeze SPR Machine mu 2002. Malo ogulitsira makinawa a Hamilton, Ohio akula kuchokera ku 2,500 square feet kufika pa 78,000 square feet, ndi 14 mphero zophimba pansi, komanso lathes, zida zowotcherera ndi zowunikira, zonse zidapangidwa makamaka kuti zizigwira ntchito muzamlengalenga ndi mafakitale azachipatala.Zosowa zamtundu kuchokera pa mainchesi 60 mpaka mainchesi 0.0005.
Luso lonseli, luso komanso mphamvu zamabizinesi zimapangitsa SPR Machine kukhala sitolo yotseguka yomwe imakumbatira zovuta zatsopano zakukula mwachangu.SPR idalumphira pamwayi pomwe imodzi mwazovuta zosinthira zitsulo kukhala zida zamkuwa zidawuka ndipo zimayenera kuwona kuchuluka kwa nthawi yozungulira SPR ingapulumutse ndi makina othamanga kwambiri.
Izi pamapeto pake zidapangitsa kuti msonkhanowu ukhale ndi zida zatsopano, chidziwitso, ziyeneretso za ogwira ntchito komanso kulemekezanso kusinthasintha komanso kusinthika kwa mkuwa.
Mwayi udabwera pomwe woyambitsa mnzake Scott Pater anali wokonda kwambiri magalimoto a RC, ndipo adaphatikiza zilakolakozo ndi abwenzi kuti athamangitse magalimoto a RC.
Mnzakeyu atapanga gawo lokonzedwanso la gawo la RC ndikuyamba kugulitsa m'masitolo ogulitsa, Pater adamuwonetsa kuti SPR ingakhale yogulitsa bwino kuposa ya China, makamaka popeza kuyitanitsa kunja kumatanthauza miyezi yodikirira kuti alandire magawo.
Chojambula choyambiriracho chinagwiritsa ntchito chitsulo cha 12L14, chomwe chinawononga ndi kukulitsa, zomwe zimapangitsa kuti zikhale zovuta kuchotsa pambuyo pa ntchito.
Aluminiyamu amathetsa vuto la dzimbiri, koma alibe mphamvu ndi kulemera kupereka bata mu galimoto yaing'ono ndi otsika likulu yokoka.
Brass imaphatikiza zonse ndi mawonekedwe owoneka bwino omwe amapangitsa chidutswacho kukhala chosangalatsa kwa makasitomala ndikulimbitsa njira yolunjika ya SPR.Komanso, mkuwa sutulutsa zinyalala zazitali komanso zomata za mbalame za SPR monga zitsulo zina, makamaka pafupifupi 4 ″ zobowoledwa zazitali.
"Brass imagwira ntchito mwachangu, tchipisi timatuluka bwino, ndipo makasitomala amakonda zomwe akuwona m'gawo lomalizidwa," adatero Pater.
Pantchitoyi, Pater adayika ndalama pakampani yachiwiri ya CNC lathe, Ganesh Cyclone GEN TURN 32-CS yamitundu isanu ndi iwiri yokhala ndi masipiko awiri a 6,000 RPM, zida 27, mizere mizere, ndi makina osindikizira a 12-foot static bar feed..
"Poyambirira tidapanga gawo la konkriti pa lathe ya SL10.Tidayenera kuyika mbali imodzi, kutenga gawo ndikulitembenuza kuti titsirize kumbuyo, "akutero Pete."Pa Ganesha, gawoli latha kwathunthu likangotuluka pamakina."Ndi makina atsopano omwe ali nawo, SPR inkafunika kupeza anthu oyenera kuti amvetse bwino momwe amaphunzirira.
Othandizira David Burton, yemwe kale anali dipatimenti yochotsa ndalama ku SPR, adavomereza vutoli.Miyezi ingapo pambuyo pake, adaphunzira khodi ya block ndi G-code yamakina aaxis awiri ndikulemba gwero la gawolo.
Mgwirizano wa SPR ndi kampani ya Cincinnati-based machinability consulting firm TechSolve inapatsa sitoloyo mwayi wapadera wokonza gawoli mogwirizana ndi Copper Development Association (CDA), yomwe ikuyimira opanga mkuwa, bronze ndi mkuwa ndi ogwiritsa ntchito..
Posinthana ndi TechSolve yowongolera magawo opanga ku SPR, malo ogulitsira alandila magawo omaliza opangidwa kuchokera kumakina ndi akatswiri azinthu.
Kuwonjezera pa kutembenuza, mbaliyo poyamba inkafunika mphero, kuboola mabowo ambiri akuya, ndi kubowola malo okhala mkati mwake.
Ma spindles angapo a Ganesh ndi nkhwangwa zinasunga nthawi yopangira, koma dongosolo loyambirira la Burton lidapangitsa kuti pakhale kuzungulira kwa mphindi 6 masekondi 17, kutanthauza kuti mayunitsi 76 amapangidwa maola 8 aliwonse.
SPR itakhazikitsa malingaliro a TechSolve, nthawi yozungulira idachepetsedwa kukhala mphindi 2 masekondi 20 ndipo kuchuluka kwa magawo pakusintha kunakwera mpaka 191.
Kuti mukwaniritse izi, TechSolve yazindikira madera angapo omwe SPR ingachepetse nthawi yozungulira.
SPR imatha m'malo mwa mphero ya mpira ndi broaching, kujowina magawo ndi kukonza mipata isanu panthawi, zomwe sizingagwire ntchito popanga zitsulo zosapanga dzimbiri kapena zitsulo.
SPR imapulumutsa nthawi yochulukirapo ndi kubowola kolimba kwa carbide pobowola, ma feed ankhanza kwambiri komanso kuya kocheperako komanso kutsika kokulirapo kwa kudula.Kulinganiza kuchuluka kwa ntchito pakati pa zopota ziwirizi kumatanthauza kuti palibe amene amadikirira winayo kuti amalize ntchito, ndikuwonjezera zotuluka.
Pomaliza, machinability mtheradi wa mkuwa zikutanthauza kuti ndondomeko akhoza kuchitidwa pa liwiro lapamwamba ndi amadyetsa ndi tanthauzo.
SPR imalola TechSolve kuwongolera ndondomekoyi kuti sitoloyo ione ubwino wogwiritsa ntchito mkuwa muzinthu zina zopangira.
Dongosolo loyambirira lopanga la Burton lidapereka poyambira, ndipo kukhathamiritsa kwake kwa SPR kumachepetsa nthawi zozungulira kwambiri.
Koma kutha kuwona njira yonse kuchokera kusanthula mpaka kukhathamiritsa kwa kupanga ndi mwayi wapadera, monganso kugwiritsa ntchito mkuwa wokha.
Monga SPR idazindikira, mkuwa umapereka maubwino ambiri, ena omwe amawonekera kwambiri pantchitoyi.
Ndi makina othamanga kwambiri amkuwa, mutha kubowola mwachangu mabowo akuya, kukhalabe olondola ndikuwonjezera moyo wa zida nthawi yayitali.
Popeza kuti mkuwa umafunikira mphamvu yocheperako kuposa chitsulo, kuvala kwa makina kumachepetsedwanso ndipo kuthamanga kwambiri kumapangitsa kuti pakhale kusokonezeka pang'ono.Pokhala ndi 90% zotsalira zamkuwa, SPR imatha kupindula ndi tchipisi ta makina kudzera pamapulogalamu obwezeretsanso.
Monga Pate akunena, "Brass imapereka zopindulitsa zazikulu.Zida zanu ndizomwe zimakulepheretsani pokhapokha mutakhala ndi zida zapamwamba zomwe zimatha kupanga makina othamanga kwambiri.Mwa kukweza makina anu, mutha kutsegula kuthekera kwenikweni kwa mkuwa. ”
SPR's Lathe Division imapanga zamkuwa kuposa china chilichonse, ngakhale shopu yonse imagwiritsanso ntchito aluminiyamu, chitsulo chosapanga dzimbiri ndi zida zapadera kuphatikiza mapulasitiki monga PEEK.Mofanana ndi ntchito zambiri zomwe SPR imapanga, akatswiri ndi kupanga, zigawo zake zamkuwa zimagwira ntchito yofunika kwambiri pofufuza malo, telemetry ya asilikali, zida zachipatala ndi ntchito zina zomwe nthawi zambiri zimaphatikizapo mapangano osagwirizana ndi mndandanda wa makasitomala, ambiri omwe ndi makasitomala.Zotsatira za SPR ndizosaloledwa.kutchulidwa.Mtundu wa ntchito zomwe msonkhano umachita zikutanthauza kuti kulolerana kumagawaniza kayendedwe ka SPR mu theka la magawo zikwi zitatu ndi zina zonse mu magawo atatu mwa magawo khumi.
Adam Estel, Director of Bars and Bars wa CDA, anati: “Kugwiritsa ntchito mkuwa popanga makina othamanga kwambiri kumathandiza kuti mphero zizilungamitsa kugulitsa zida zatsopano chifukwa zimachulukitsa ndalama komanso zokolola komanso kuyambitsa bizinesi yatsopano.Ndife okondwa kwambiri ndi zomwe SPR yapeza, zomwe zikuyenera kulimbikitsa masitolo ena kuti azikhala aukali ndi mkuwa. "
George Adinamis, Senior Engineer ku TechSolve, adayamika SPR chifukwa chokhala omasuka, nati, "Ndichiyamikiro chachikulu kuti SPR imagawana zambiri komanso kutikhulupirira, ndipo ntchito yonseyi ndi imodzi yogwirizana kwathunthu."
M'malo mwake, makasitomala ena a SPR amadalira Scott Pater kuti athandizidwe ndi chitukuko cha gawo, kapangidwe kagawo, ndi upangiri wazinthu, kotero SPR imatha kugwiritsa ntchito mkuwa pazinthu zina ndikuwona makasitomala awo amatsatira malangizo ake.
Kuphatikiza pa kupanga ndi kupanga zida za makasitomala ena, adakhala wogulitsa yekha, ndikupanga mwala wamanda womwe umalola ma lathe ndi mphero zopangira makina ozungulira ndi lathyathyathya ndi ma castings.
"Mapangidwe athu amatipatsa magwiridwe antchito apamwamba komanso opepuka kulemera, komabe amphamvu kwambiri kotero kuti munthu amatha kuyiyika pamakina," adatero Pater.
Zokumana nazo zapamwamba za SPR zimalimbikitsa ukadaulo wa projekiti, mgwirizano, komanso njira yopambana, mkuwa umagwira ntchito yofunika kwambiri pamayendedwe ake.
Ndichidziwitso chophatikizika ichi chowunikira zabwino zogwira ntchito ndi mkuwa, SPR Machine imayang'ana magawo ena osinthika kuti apititse patsogolo kuchita bwino komanso kupindula.
