Hlala nabazanyiwe nabayiqiniso? Noma hamba nento entsha?

Izitolo eziningi zemisebenzi zibambelela ezinhlelweni zamathuluzi ezivamile, ezingabizi. Amafulethi e-ER namafulethi aseWeldon ayazanywa futhi ayiqiniso; ziyasebenza futhi ziqinisekisiwe. Ngesikhathi esifanayo, ubuchwepheshe bemishini obusha, obuthuthukisiwe, obufana nemishini ye-multi-axis, bungase busebenze kangcono uma izibambi zamathuluzi ezintsha, ezithuthukile (nazibiza kakhulu) zisetshenziswa.

Ngenxa yalokho, izitolo zemisebenzi zibhekana nokukhetha okwengeziwe futhi kudingeka ukuhlaziya okwengeziwe.

"Izindlela ezimbili ezibalulekile zokwahlulela ikhwalithi yesistimu yokubamba amathuluzi ukuphela nokuphindaphindeka," kusho u-Luke Pollock, umphathi womkhiqizo we-Walter USA LLC, Waukesha, Wis. "Ngokwalo mbono, abanikazi bama-shrink-fit and hydraulic holders bayingxenye 'engcono kakhulu'. Bobabili bathintana ngokuphephile ne-cylindrical ground cylindrical systems futhi banikeze amasistimu wokuphinda aphindwe kabili. Isigaba 'sokungcono'

UPollock uthe amandla okubamba angenye into ecatshangelwayo. “Ukwenza isinqumo ngalo mbono kushintsha ukuthi yibaphi abanikazi esibabheka 'abangcono kakhulu,'” esho. "Isimeli se-Weldon shank sisebenzisa uxhumano olwenza kungenzeki ukuthi ithuluzi lishelele noma liphume. Ngakho-ke, ngalesi simeli, singaphusha uhlelo lomshini kanzima kakhulu, kuze kufike kumkhawulo wohlelo lokusebenza. Izibambi ze-Shrink-fit kanye ne-hydraulic nazo zinikeza amandla okuhle kakhulu okubamba. Kodwa-ke, ezimeni ezithile ezingase zihlanganise amazinga aphezulu okususwa kwempahla noma ukuxhumana okukhulu phakathi kwethuluzi nokudonsa okuthile noma ukuphuma kwe-lip kungenzeka kube khona."

Okuningi kuncike ekutheni yiziphi izinhlelo zokusebenza ezihilelekile. U-Drew Strauchen, iphini likamongameli omkhulu we-GWS Tool Group, i-Tavares, Fla., Wathi "ngokuvamile" isigaba esihle sihlanganisa abanikazi bomshini wokugcina kanye nama-collets; kangcono kufaka phakathi ama-collet chucks anembe kakhulu nama-mill chucks; futhi okuhle kakhulu kufaka phakathi i-shrink-fit, i-hydraulic, kanye ne-press-fit.

"Izisekelo eziyisisekelo zomphathi omkhulu ukuqina, amandla okubamba, ukunemba kokuphuma kanye nokulinganisela," esho. "Njengoba izinhlelo zokusebenza zisukela ekuqineni kuye ekuqedeni, ukukhiqizwa okuphansi kuye ekukhiqizeni okuphezulu, kanye nokubekezelela okuphansi kuya kokuphezulu, ukubaluleka komnikazi kanye nezimfanelo zakhe ngazinye ziba bucayi kakhulu."

Ukulawula Ukhiye We-Runout to Tool Life, Ukunemba

U-Edwin Tonne, uchwepheshe wokuqeqeshwa nensizakalo wezobuchwepheshe we-Horn USA Inc., uFranklin, Tenn., ucaphune izibonelo zezicelo zezigaba ezahlukene.

Ama-hydraulic holders, uthe, angcono kakhulu ekufakeni izicelo zokumba, ukuqeda ngesivinini esikhulu kanye nokuphinda kwenziwe kabusha. I-Shrink-fit ifaneleka kakhulu ukugaya okungalungile, ukugaya, ukubhoboza kanye nokwenza kabusha; kanye nezinhlelo ze-collet ezisebenza kahle kakhulu zilungele ukugaya, ukugaya, ukubhoboza kanye nokwenza kabusha.

U-Tonne uphinde wachaza okucatshangelwayo lapho ekhetha izinketho zokubamba amathuluzi. Ngamathuluzi okumba noma okuvuselela kabusha, uthe, ukuphuma "kubalulekile empilweni yamathuluzi ezomnotho kanye nokunemba kobukhulu." Ngokugaywa okungalungile, ukuphuma nakho kubalulekile “kanye namandla okubamba i-shank. Njengoba isidingo setorque kusiphathi samathuluzi siphezulu, ingozi yokudonsa inkulu.”

Wathi u-Walter's Pollock, "Kubalulekile ukufanisa uhlobo olulungile lwesiphathi samathuluzi nesicelo. Indlela engcono yokusibheka iwukucabangela ukuthi yisiphi isici somphathi wamathuluzi esibaluleke kakhulu kuhlelo lokusebenza. Izinhlelo zokusebenza ezinzima zizohlomula kakhulu kumphathi wamathuluzi onamandla amakhulu okubamba. Ekuqedeni imisebenzi, lapho ukubekezelelana okunembile kanye nokuqedwa okuhle kuwumgomo, abanikazi bamathuluzi kanye nokuphinda okumbalwa kufanele kube ukuphindaphinda okuncane kokuqala."

Isibalo sezitolo zemisebenzi singahluka. U-Dan Doiron, umphathi womkhiqizo we-Emuge Corp., e-West Boylston, Mass., uchaze okucatshangwayo lapho ekhetha izinketho zokubamba amathuluzi ezinhlobo ezahlukene zamathuluzi okusika.

“Uma ngibona ithuluzi elinefulethi lase-Weldon, lokho ngokuvamile kubonisa ukuthi leli thuluzi lenzelwe ukugaya okunolaka,” esho. "Lokho akusho ukuthi awukwazi ukusebenzisa ithuluzi ukuze uqedele, kodwa iflethi lase-Weldon lingezwe ethuluzini lokuvimbela ukuphuma. Ukuze uqine, ikholethi yokukhiya iphinikhodi iyisinqumo esihle. Ngomshini wezindawo ze-3D ze-mold core noma i-cavity, isiphathi samathuluzi somkhiqizo we-Emuge FPC sizoletha izinga eliphezulu lokunemba ngaphandle kwebhokisi elinobungane elikhushuliwe. umnikazi.”

Ukuba Namathuluzi Okuvame Ukunganakwa

Ezitolo zemisebenzi, umbuzo manje uthi ungaqhubeka kanjani. Isibonelo, izitolo zemisebenzi kufanele zikhethe nini ukutshala izinsiza futhi ziqhubekele phambili?

“Ukuba namathuluzi kuvame ukunganakwa, ikakhulukazi uma kuthengwa umshini omusha,” kusho uDoiron. "Kodwa-ke, izitolo kufanele zicabangele ukuthuthukisa isu lazo lokubamba amathuluzi uma umshini uthengwe ukuze kwandiswe umkhiqizo futhi usebenze ngezinga eliphezulu lokunemba. Isibonelo, ukusebenzisa izibambi ze-side-lock ezindala nokulindela ukuthi izinga lokusebenza lithuthuke kuzogcina kudumaza. Umnikazi usalokhu engalungile kungakhathaliseki ukuthi usemshinini omdala noma emshinini wokuphotha omusha."

Okunye ukucatshangelwa kuncike kusayizi wezitolo zemisebenzi. "Isenzo esikhulu sokulinganisa siphakathi kokuguquguquka nokusebenza," kusho u-Alan Miller, umphathi wobunjiniyela kanye nomphathi womkhiqizo weBIG Kaiser Precision Tooling Inc., Hoffman Estates, Illinois. "Uma uhlelo lunokuvumelana nezimo okwengeziwe, ukusebenza okuncane okungenzeka luzokunikeza kuzinhlelo zokusebenza ezithile. Ezindaweni zokukhiqiza okuphezulu, ufuna ukugxila esixazululweni esisebenza kahle kakhulu. Lapho singena ebangeni lemisebenzi emincane kakhulu, ukuba nokuguquguquka kwesistimu yomnikazi wamathuluzi kungase kuphazamise ukuthola ukusebenza okuphezulu kumathuluzi okusika."

Uma kukhulunywa ngokutshala imali kwezobuchwepheshe obusha, “Kulula ukwenza ngezitolo ezinkulu,” kusho yena. “Kunzima ukuthi isitolo esincane siyeke ukuguquguquka.”

Noma kunjalo, izitolo zemisebenzi ziyahlola ukuthi ukutshala imali kubuchwepheshe obusha kuzifanele yini izindleko ezincishisiwe ezilahliwe nempilo ende yamathuluzi.

Inzuzo Enkulu Ye-Holemaking

"Izisekelo eziyisisekelo zomphathi omkhulu ukuqina, amandla okubamba, ukunemba kokuphuma kanye nokulinganisela," kusho u-GWS' Strauchen. "Amathuluzi okwenza ama-holemaking ahlomula ikakhulukazi kubaphathi abanamadigri aphezulu okunemba kokuphuma kanye nebhalansi. Izigayo zokuphela zizuza okufanayo kodwa ngokuvamile zidinga abanikazi abanokuqina okwengeziwe namandla okubambelela ukuze baphathe kangcono imithwalo yeradial namandla okudonsa adalwe kusetshenziswa izigayo zokuphela kwe-helical. Ngezinye izikhathi, amandla okukhipha aba ngendlela yokuthi isistimu yokulingana yemishini efana ne-side-lock noma isistimu yokukhiya ngokuphephile iyadingeka."

Abaphathi bathi noma nini lapho isitolo sitshala imali entsha yamathuluzi, ukugcinwa kwamathuluzi kufanele kuhlolwe. “Uma isitolo sitshala imali ezikhungweni zemishini emisha, kubalulekile ukuthi siphinde siqedele ukuthenga ngokuphatha amathuluzi amasha,” kusho uTonne wakwaHorn USA. "Akuwenzi umqondo wezomnotho ukuzuza izinzuzo zokukhiqiza, ake sithi, isikhathi esisheshayo se-chip-to-chip uma sichithwa ekushintsheni kwamathuluzi ngenxa yempilo embi yamathuluzi."

UStrauchen uveze umbono ofanayo. Lapho ebuzwa ukuthi isitolo kufanele sicabangele ukuthuthukisa ukubamba kwamathuluzi, waphendula: “Ngaphandle kwempendulo esobala yokuthi ‘njalo,’ impendulo enengqondo kakhulu yilapho bethenga ithuluzi lomshini elisha. Ngaphandle kwezinhlelo zokusebenza zomshini ngokwazo nokusebenza, amasistimu wokubamba amathuluzi ekhwalithi ephezulu ngokuvamile anezimfanelo ezingcono zokulinganisela futhi agcina elingana kangcono—ngokwesibonelo, amatheyipu e-V-flange anembe kakhudlwana, azokwandisa ukuphila kwemoto yakho endala, noma abophe imoto yakho entsha. kufanele ufake izinto zokuphotha esezike zasetshenziswa endaweni entsha yokuphotha.”

Enye ingxenye yokuhlola iwukuthi uhlelo olusha lokubamba amathuluzi luyoba nalo kumathuluzi amasha. Impilo yamathuluzi ethuthukisiwe iyisizathu esikhulu sokwenza ushintsho.

"Mhlawumbe indawo elula yokubona i-ROI ekuthuthukiseni ikhwalithi yesistimu yokubamba amathuluzi ukusebenza kwethuluzi," kusho u-Walter's Pollock. "Impilo yamathuluzi yinto iningi lethu elikwaziyo ukuyigada. Ukuthola impilo yamathuluzi engeziwe ethuluzini elilodwa kusho izingxenye ezengeziwe zezindleko zokukhiqiza ezifanayo. Lokhu kusho ukuthi kufinyelelwa izindleko eziphansi ngengxenye ngayinye."

Futhi, wathi, amazinga aphezulu okukhiqiza angase azuzwe. "Uma kubalwa izinga lomthwalo womshini kanye no-opharetha, izikhathi zomjikelezo omfushane zinomthelela omkhulu ekwehliseni izindleko ngengxenye ngayinye," kusho u-Pollock. "Izindleko eziphelele ngengxenye ngayinye ziyindlela eqinile yokubala inzuzo yomnikazi wamathuluzi othuthukisiwe."
