Balekane ba bararo ba fane ka phihlelo ea bona e fapaneng ea tlhahiso le ts'ebetso le li-initials tsa bona tsa ho qetela ho fumana SPR Machine ka 2002. Lebenkele lena la mochine oa Hamilton, Ohio le hōlile ho tloha ho 2,500 maoto a lisekoere ho ea ho 78,000 maoto a lisekoere, le 14 mill e koahelang fatše, hammoho le lathes, lisebelisoa tsa ho tjheseletsa le ho hlahloba, kaofela li etselitsoe ho sebeletsa liindasteri tsa sefofane le tsa bongaka.likheo tsa boleng ho tloha lisenthimithara tse 60 ho isa ho tse 0.0005.
Talenta ena kaofela, boiphihlelo le matla a khoebo li etsa SPR Machine lebenkele le bulehileng le amohelang mathata a macha a kholo ka cheseho.SPR e ile ea qhoma monyetla oo ha e 'ngoe ea liqholotso tsa ho fetola tšepe ho lisebelisoa tsa karolo ea koporo e ne e hlaha' me e hloka ho bona hore na nako ea potoloho ea SPR e ka boloka nako e kae ka machining a lebelo le phahameng.
Sena se ile sa qetella se lebisitse workshop ho lisebelisoa tse ncha, intuition, mangolo a basebetsi le tlhompho e nchafalitsoeng bakeng sa ho feto-fetoha ha maemo le machinability ea koporo.
Monyetla o ile oa tla ha mothehi-'moho Scott Pater e ne e le motho ea chesehelang likoloi tsa RC, 'me a kopanya litakatso tseo le metsoalle ho matha likoloi tsa RC tse sa tsamaeeng tseleng.
Ha motsoalle enoa a theha karolo e nchafalitsoeng ea karolo ea RC 'me a qala ho fana ka eona mabenkeleng a ho itlosa bolutu, Pater o ile a mo bontša hore SPR e tla ba morekisi ea molemo ho feta mofani oa thepa oa Chaena, haholo-holo kaha ho odara mose ho maoatle ho bolela likhoeli tsa ho emela ho fumana likarolo.
Moqapi oa pele o ne o sebelisa tšepe ea 12L14, e ileng ea senyeha le ho atolosa, e leng ho etsang hore ho be thata ho e tlosa ka mor'a tšebeliso.
Aluminium e rarolla bothata ba ho bola, empa ha e na matla le boima ba ho fana ka botsitso ka koloing e nyenyane e nang le setsi se tlaase sa matla a khoheli.
Brass e kopanya ka bobeli le ponahalo e khahlehang e etsang hore sengoathoana se ipiletse ho bareki le ho matlafatsa mokhoa o shebaneng le boleng ba SPR.Hape, koporo ha e hlahise lithōle tsa sehlaha sa nonyana ea SPR e telele le e khomarelang joaloka litšepe tse ling, haholo-holo likarolong tse ka bang 4 ″ tse telele tse chekiloeng.
"Brass e sebetsa kapele, lichifi li tsoa hantle, 'me bareki ba rata seo ba se bonang karolong e felileng," ho boletse Pater.
Bakeng sa mosebetsi ona, Pater o ile a tsetela ho lathe ea bobeli ea k'hamphani ea CNC, mochini oa Switzerland oa Ganesh Cyclone GEN TURN 32-CS o nang le li-spindle tse peli tsa 6,000 RPM, lisebelisoa tse 27, litataiso tsa mela, le mochini oa khatiso oa 12-foot static bar feed..
"Qalong re ile ra kenya karolo ena ea konkreite ka mochine oa SL10 lathe.Re ile ra tlameha ho cheka lehlakore le le leng, re nke karolo ebe re e phethola ho qetela ka morao, ”ho bolela Pete."Ganesha, karolo e felile ka ho feletseng hang ha e tsoa ka mochine."Kaha ba na le mochini o mocha, SPR e ne e hloka ho fumana batho ba nepahetseng ho utloisisa hantle tsela eo e ithutang ka eona.
Opereishene David Burton, eo pele e neng e le oa lefapha la ho lefa la SPR, o amohetse phephetso ena.Likhoeli tse 'maloa hamorao, o ile a ithuta block coding le G-code bakeng sa mochine oa li-axis tse peli' me a ngola khoutu ea mohloli bakeng sa karolo eo.
Tšebelisano ea SPR le feme ea boeletsi ea machinability e thehiloeng Cincinnati TechSolve e file lebenkele monyetla o ikhethang oa ho ntlafatsa karolo ena ka tšebelisano 'moho le Copper Development Association (CDA), e emelang baetsi le basebelisi ba koporo, boronse le koporo..
E le phapanyetsano bakeng sa TechSolve e tsamaisang liparamente tsa tlhahiso ho SPR, mokatong oa lebenkele o tla fumana litekanyo tsa ho qetela tse ntlafalitsoeng ho tsoa ho mochini le litsebi tsa thepa.
Ntle le ho phethoha, qalong karolo e ne e hloka ho siloa ha bolo, ho phunya masoba a mangata a tebileng, le ho phunya libaka tse behang ka hare bophara.
Li-spindle tse 'maloa tsa Ganesh le lilepe li bolokile nako ea tlhahiso, empa kemiso ea pele ea tlhahiso ea Burton e ile ea fella ka karolo ea potoloho ea metsotso e 6 metsotsoana e 17, ho bolelang hore ho ne ho etsoa li-unit tse 76 ka nako e 'ngoe le e 'ngoe ea lihora tse 8.
Kamora hore SPR e kenye tšebetsong likhothaletso tsa TechSolve, nako ea potoloho e ile ea fokotsoa ho ba metsotso e 2 metsotsoana e 20 mme palo ea likarolo ka nako e 'ngoe e nyolohetse ho 191.
Ho fihlela ntlafatso ena, TechSolve e khethile libaka tse 'maloa moo SPR e ka fokotsang linako tsa potoloho.
SPR e ka nka sebaka sa ho sila ka bolo ka broaching, likarolo tse kopanyang le ho lokisa li-slots tse hlano ka nako, tseo ho ka etsahalang hore li ke ke tsa sebetsa ha ho etsoa tšepe e sa hloekang kapa likarolo tsa tšepe.
SPR e boloka nako e ngata le ho feta ka liboro tse tiileng tsa carbide bakeng sa ho cheka, lijo tse mabifi le botebo bo nang le lihokelo tse fokolang le botebo bo boholo ba ho seha bakeng sa ho khoasolla.Ho leka-lekanya mojaro oa mosebetsi pakeng tsa li-spindle tse peli ho bolela hore ha ho motho ea emelang e mong hore a phethe mosebetsi, ho eketsa tlhahiso.
Qetellong, machinability e feletseng ea koporo e bolela hore ts'ebetso e ka etsoa ka lebelo le phahameng le ho fepa ka tlhaloso.
SPR e lumella TechSolve ho fokotsa ts'ebetso e le hore lebenkele le bone melemo ea ho sebelisa koporo likarolong tse ling tsa tlhahiso.
Morero oa pele oa tlhahiso ea Burton o fane ka qalo, 'me lintlafatso tsa SPR li fokolitse linako tsa potoloho le ho feta.
Empa ho khona ho bona ts'ebetso eohle ho tloha ho tlhahlobo ho isa ho ntlafatso ea tlhahiso ke monyetla o ikhethang, joalo ka tšebeliso ea koporo ka boeona.
Joalokaha SPR e hlokometse, koporo e fana ka melemo e mengata, e meng ea eona e hlahelletseng morerong ona.
Ka machining a lebelo le phahameng a koporo, o ka phunya masoba a tebileng ka potlako, oa boloka ho nepahala le ho eketsa bophelo ba lisebelisoa nakong ea lichifi tse telele.
Kaha koporo e hloka matla a fokolang a ho sebetsa ho feta tšepe, ho roala ha mochini ho boetse ho fokotsehile 'me lebelo le phahameng le etsa hore ho be le tšitiso e fokolang.Ka koporo e fihlang ho 90%, SPR e khona ho etsa phaello ho tsoa ho lichifi tsa mochini ka mananeo a ho e sebelisa hape.
Joalo ka ha Pate a re, "Brass e fana ka phaello e kholo ea tlhahiso.Thepa ea hau ke eona e u fokotsang ntle le haeba u na le lisebelisoa tse tsoetseng pele tse ka etsang machining ka lebelo le holimo.Ka ho ntlafatsa mechini ea hau, u ka notlolla bokhoni ba 'nete ba koporo. ”
SPR's Lathe Division e sebetsa ka koporo ho feta eng kapa eng, leha lebenkele lohle le boetse le sebetsana le aluminium, tšepe e sa hloekang le lisebelisoa tse ikhethang ho kenyeletsoa le polasetiki e kang PEEK.Joalo ka boholo ba mosebetsi oo SPR e o qapang, baenjiniere le ho o etsa, likarolo tsa eona tsa koporo li phetha karolo ea bohlokoa ho hlahlobisiseng sebaka, telemetry ea sesole, lisebelisoa tsa bongaka le lits'ebetso tse ling tseo hangata li kenyelletsang litumellano tsa ho se senole le manane a bareki, bao bongata ba bona e leng bareki.Liphetho tsa SPR ha lia lumelloa.ho bitsoe.Mofuta oa mosebetsi oo workshop e o etsang o bolela hore mamello e arola tšebetso ea SPR hoo e ka bang halofo ea likete tse tharo le tse ling kaofela ka karolo ea boraro-boshome.
Adam Estel, Mookameli oa Libara le Libara oa CDA, o itse: “Ho sebelisa koporo bakeng sa mochini o potlakileng haholo ho thusa limilo ho lokafatsa matsete a thepa e ncha kaha e eketsa lekeno le tlhahiso le ho bula khoebo e ncha.Re thabile haholo ka seo SPR e se finyeletseng, se lokelang ho susumetsa mabenkele a mang hore a be mabifi le ho feta ka koporo. "
George Adinamis, Moenjiniere e Moholo oa TechSolve, o rorisitse SPR ka ho buleha, a re, "Ke thoriso e kholo hore SPR e arolelana tlhahisoleseling le ho re tšepa, mme ts'ebetso eohle ke ea tšebelisano e felletseng."
Ha e le hantle, bareki ba bang ba SPR ba itšetlehile ka Scott Pater bakeng sa thuso ka karolo ea ntlafatso, karolo ea moralo, le keletso ea lintho tse bonahalang, kahoo SPR e ka sebelisa koporo mererong e meng le ho bona bareki ba bona ba latela keletso ea hae.
Ntle le ho rala le ho etsa likarolo tsa bareki ba bang, e ile ea e-ba morekisi ka boeena, a etsa lejoe la lebitla le lumellang li-lathe le li-mill tse nang le li-axis tse 'nè ho pota-pota le li-workpieces tse bataletseng le li-castings.
"Moqapi oa rona o re fa ts'ebetso e phahameng 'me o bobebe ka boima, leha ho le joalo o matla haholo hoo motho a ka o kenyang mochine," ho boletse Pater.
Boiphihlelo bo tsoetseng pele ba SPR bo khothaletsa boqapi ba projeke, tšebelisano 'moho le mokhoa oa ho atleha, ka koporo e bapala karolo ea bohlokoa le ho feta tšebetsong ea hae.
Ka phihlelo ena e kopantsoeng e totobatsang melemo ea ho sebetsa ka koporo, SPR Machine e tla sheba menyetla e meng ea ho fetola likarolo ho ntlafatsa katleho le phaello.
