Ngemuva kweminyaka eyishumi nanhlanu yokwakha, ukuhlola, nokushintsha izinjini zokuphotha, siye sabona wonke amaphutha encwadini: umuntu othanda ukuzilibazisa owathenga iyunithi yokupholisa umoya engu-24,000 rpm elindele ukusika insimbi, isitolo esasibiza ukuphotha okungu-2.2 kW ngegantry engu-2,000 kg, ifektri eyayisebenzisa ibhere le-S6/7 izinkuni phakathi nezinyanga ezintathu zashisa izikhonkwane ezingu-2. Lokhu kubuyekezwa kwe-spindle motor kukhona ukuze ungaphindi lawo maphutha.
Ngezansi kukhona ama-spindle motors angu-5 aphezulu ebesingawafaka emishinini yethu ngo-2026 - abalwa ngokusebenza komhlaba wangempela, inani, nokusekelwa. Kungakhathaliseki ukuthi uzingela i-spindle motor ehamba phambili yerutha ye-cnc ngesabelomali, imoto yokuphotha ehamba phambili ye-cnc mill yensimbi, noma iyunithi ethule ye-ATC yesitolo esincane sasegaraji, kukhona owinile kulolu hlu lwakho.
Ngaphambi kohlu, indlela yokwenza. Ukuqhathanisa okufanelekile kwe-spindle motor akukwazi ukwenziwa emanzini kuphela. Sishaye iyunithi ngayinye kuma-axes amahlanu:
I-torque yangempela ku-RPM ewusizo - hhayi ukuphakama kwe-nameplate, kodwa i-torque oyitholayo ku-2,000–12,000 rpm.
Ukuzinza kwe-thermal - ingabe ukuphuma kugijima ngemuva kwamahora amane okusika? Amayunithi apholile ngamanzi ngokuvamile aphumelele.
Izinga lomsindo - ngoba injini yokuphotha ethulile iyodwa ozoyigijima usuku lonke ngaphandle kokuvikela indlebe.
Ukuphelela kwekhithi - ingabe ithunyelwa njengekhithi yokuphotha epholile emanzini yangempela noma i-vfd spindle kit , noma ingabe kufanele uthole i-VFD, amakholethi, futhi ukhweze ngokuhlukana?
Iwaranti nokwesekwa — ubani obamba ucingo lapho i-VFD iphonsa ikhodi yephutha ngo-9 ebusuku ngoMgqibelo?
Ukube besingakwazi ukuhambisa insipho eyodwa kuphela iminyaka emihlanu ezayo, bekungaba yilokhu. I-ER20 epholiswe ngamanzi engu-3.7 kW iyindawo emnandi yokusebenza kwe-CNC spindle: i-torque eyanele ukusika i-aluminiyamu ngokungathi sína, ithule ngokwanele ukuba isebenze egaraji, futhi iminyene ngokwanele ukukhwela kuma-router amaningi angu-60×90 cm. Lesi ukukhetha kwethu kwemoto ehamba phambili ye-cnc spindle ngemali ngo-2026.
Amandla wangempela aqhubekayo angu-3.7 kW (S1), hhayi isilinganiso esikhuphukayo se-S6 osibona ezinhlwini ezishibhile.
Ibhantshi lamanzi lihlala lithwala izinga lokushisa phakathi kuka-3 °C phakathi noshintsho lwamahora angu-12 - ukuphuma kwamanzi kuhlala ngaphansi kuka-0.003 mm usuku lonke.
I-ER20 collet yamukela ama-shanks asuka ku-1–13 mm, afaka u-90% wezigayo emakethe.
Igijima cishe ku-68 dB(A) ngo-12,000 rpm kupholile kupholile - eduze nendawo ethulile ye-spindle motor yezitolo zasekhaya.
Izitolo ezincane zendwangu ezisika izindawo ezivalekile ze-aluminium, abenzi besikhunta benza insimbi elula, kanye nabathandi bokuzilibazisa asebekhulile kuneyunithi engu-2.2 kW futhi abafuna itorque yangempela. Futhi iyimoto yethu yokuphotha ehamba phambili enconyiwe ye-aluminium esigabeni esingaphansi kwe-$1,500.
Iyunithi engu-2.2 kW iyi-spindle esiyincoma kuwo wonke umuntu othenga okokuqala ngqa i-CNC ofuna ukusika insimbi. Iyinjini yokuphotha engcono kakhulu yama-cnc router hobbyists kuhlaka lwensimbi eshiselwe, futhi ihambisana kahle ne-3 kW VFD. Ngeke ihoge insimbi engu-4140, kodwa izobhekana ne-aluminium, ithusi, nensimbi ethambile yokuqeda impelasonto yonke.
I-torque engu-45% ngaphezu kweyunithi engu-1.5 kW, enesisindo esingu-1 kg kuphela esengeziwe.
Ukupholisa amanzi kusho ukuthi i-drift ihlala eduze kweqanda ngisho nemisebenzi emide yokuqopha izimpawu.
Ithunyelwa njengenketho yekhithi yokuphotha ye-vfd ephelele - i-spindle, i-VFD, amakholothi, ubakaki wokukhweza, nekhebula elingu-5 m ebhokisini elilodwa.
Uma ujwayele ukusika i-aluminium ibe wugqinsi kuno-3 mm, noma usebenzisa amaqoqo ezingxenye ezingu-10+, i-3.7 kW ithola inani layo ngenyanga yokuqala. Inamandla angu-2.2 kW iwucingo olufanele ezitolo zezimpawu zezinkuni kanye namagaraji abonisa ukukhanya.
Kubenzi bezinkuni, abakhi be-PCB, nabenzi bezimpawu be-acrylic, injini yokuphotha engcono kakhulu yokhuni akuyona enkulu kakhulu - iyona ephotha kancane ngokuhlanzekile ngo-24,000 rpm ngaphandle kokulahla amanzi emshinini wakho. Le yunithi epholisa umoya engu-1.5 kW ifana ncamashi: yixhume, yifake, bese uyisebenzise.
Ayikho i-chiller, ayikho imigqa yamanzi, ayikho i-antifreeze ebusika. Ukusetha-futhi-ukhohlwe kwangempela.
24,000 rpm iyindawo emnandi ye-MDF ehlanzekile, engashi namachopho e-acrylic.
Ilula ngokwanele (4.2 kg) ukuze igibele kuma-gantries amancane angakwazi ukuthatha iyunithi epholiswe ngamanzi.
Ipholile emoyeni, ngakho-ke lindela u-~75 dB womsindo wabalandeli — lokho okungaphezulu kweyunithi epholiswe ngamanzi. Uma ugawula izinkuni isikhathi esingaphezu kwehora ngosuku, ukuvikela izindlebe kuyisibopho. Ungaceli ukuthi ukusika insimbi; ngeke kuphele kahle.
Lesi yi-spindle eshintsha irutha ye-CNC yegaraji ibe umshini wokukhiqiza wangempela. I -atc spindle yendawo yezitolo ezincane izikhokhela yona okokuqala ngqa usebenzisa inqwaba yabakaki abangu-20, ngayinye idinga umshini wokubhoboza ophakathi nendawo, isigayo sokugcina esiqinile, isigayo sokuqeda, kanye nokuthepha - ngaphandle kokuma ukuze ushintshanise ama-collet ngesandla.
Ukushintsha kwamathuluzi womoya: Umyalo we-M6 ushintshanisa abanikazi be-BT30 ngemizuzwana engu-2–3.
I-5.5 kW epholiswe ngamanzi, umsebenzi we-S1 - isebenza impelasonto yonke ingagadiwe.
I-BT30 taper ibamba u-0.002 mm runout, engcono kakhulu kunanoma iyiphi i-ER collet ngaphansi komthwalo oseceleni.
Ihambisana nama-racks amathuluzi amaningi eziteshi ezingu-6-16 avela kubalawuli baseShayina nabaseYurophu.
Izitolo ezincane zemisebenzi ezisebenzisa amaqoqo okukhiqiza, izimboni zefenisha ezenza i-CNC enezidleke ngamathuluzi amaningi, nanoma ubani osekhathele ukumisa umshini izikhathi ezingu-15 ingxenye ngayinye. Akuyona iyunithi ye-hobbyist — inani kanye nemfuneko ye-airline ikubeka 'endaweni yebhizinisi langempela'. Kodwa uma usuyisebenzisile i-ATC, awusoze wabuyela emuva.
Lapho impahla iyinsimbi, udinga isigaba esihlukile sokuphotha. I-7.5 kW BT40 iwukukhetha kwethu injini yokuphotha ehamba phambili yabathengi be-cnc mill asebekhulile irutha yabo futhi bafuna ukusikeka kwangempela ngensimbi ethambile futhi engagqwali. Akuyona i-spindle yokukhiqiza eyigiya elingu-30 kW, kodwa ohlakeni olufanele lokugaya izozibambela mathupha ngokumelene namathuluzi omshini abiza imali ephindwe kathathu.
I-BT40 taper - iqinile ngokwanele ukusikeka kwehlombe okujule okungu-6 mm ngo-1018.
Ijakhethi lamanzi + ukugcotshwa kukawoyela ongakhetha kukho kugcina izinga lokushisa lizinzile ekugijimeni kwensimbi okude.
Ilinganiselwe i-S1 emsebenzini ongu-100 % - yakhelwe ukukhiqizwa, hhayi umsebenzi wokuzilibazisa.
Abakhi bemishini bahlanganisa ezikhungweni zokumaka eziqondile, izitolo ezincane zesikhunta, nanoma ubani othuthukayo ukusuka ku-BT30 router spindle ukuya ekususeni insimbi yangempela. Uma ifremu yomshini wakho ingakwazi ukushwiba ikhala le-BT40 (~85 mm ububanzi), namathela #4 BT30 ATC.
Lesi sigaba sifinyeza konke esikufundile kube umhlahlandlela osebenzayo wokuthenga wemoto yokuphotha ongawusebenzisa kunoma yiluphi uhlu, hhayi olwethu kuphela.
Uma uhlu luthi ikhithi yokupholisa amanzi epholile , bhekisisa. Uhlu olushibhe kakhulu lukudayisela i-spindle yedwa. Ikhithi yangempela kufanele ifake:
I-spindle motor ngokwayo (ene-shaft, ikhala, ne-collet nut).
I-VFD enosayizi ongu-20–30 % ngaphezu kwe-spindle current (lena uhhafu wekhithi yokuphotha ye-vfd ).
I-spindle Mount flange (80 mm noma 100 mm ID).
Isethi ye-collet (ER11/ER20/ER32, ngokuvamile izingcezu eziyi-8).
Okwamayunithi apholise ngamanzi: amapayipi, okokufakwayo, nesincomo sokupholisa (i-chiller ivamise ukuthengiswa ngokuhlukana).
Uma ukufakwa kuhlu kungakhulumi nge-VFD, bhajethela u-$200–$400 owengeziwe. I-spindle engu-$200 ngaphandle kwe-VFD efanisiwe iyisivalo somnyango.
Umsindo ubaluleke kakhulu kunalokho abathengi abaningi abakuvumayo. Iphinifa elingu-75 dB(A) elipholile emoyeni eduze kwedeski lakho amahora angu-4 lizokunika ikhanda elibuhlungu. Ama-spindle apholile ngamanzi agijima ku-65–70 dB(A) ngoba okuwukuphela umoya onyakazayo usuka kufeni elipholile, hhayi ikheji le-squirrel elingu-24,000 rpm.
Ukupholisa umoya 1.5–2.2 kW: 72–78 dB(A) — uhlelo lokuvikela indlebe.
Ukupholisa amanzi 2.2–5.5 kW: 65–70 dB(A) — ileveli yengxoxo uma i-chiller ingaphandle kwedokodo.
I-BT30/BT40 spindle enefeni ehlanganisiwe: 70–75 dB(A) — idokodo elivaliwe liyanconywa.
Ividiyo engezansi idlula ekufakweni kwangempela kwekhithi yokuphotha epholiswe ngamanzi, okuhlanganisa izintambo ze-VFD, izinguquko zekholethi, nezinga lomsindo elilinganiswa imitha elingu-1.
Lona umnyombo wanoma yisiphi isiqhathaniso se-spindle motor : fanisa i-spindle nento eyinhloko, hhayi iphrojekthi yephupho.
I-RPM ephezulu (18k–24k), i-torque ephansi, i-air-cooled ilungile. Isabelomali 1.5–2.2 kW. Ungachithi ngokweqile ekupholiseni amanzi - umthwalo wokushisa ekusikeni izinkuni unesizotha.
Ibhendi epholile ngamanzi engu-2.2–5.5 kW, ER20/ER32, 8k–18k rpm. Udinga i-torque ebangeni eliphakathi, futhi udinga ukuzinza okushisayo ukuze ubambe ukubekezelelana. Lesi yi- #1 noma # 2 spindle ohlwini lwethu.
Usendaweni ye-BT30/BT40, ubuncane obungu-5.5 kW. Yeqa amarutha e-ER ngokuphelele. Lesi yi-#4 noma #5 yokuphotha.
Uma ukhumbula into eyodwa kuphela, khumbula lokhu:
Ukhuni / uphawu / PCB shop → #3 Holry 1.5 kW air-ipholile.
Umuntu wokuzilibazisa ofuna ukusika i-aluminium → #2 Holry 2.2 kW epholiswe ngamanzi.
Isitolo esincane sendwangu, ehamba phambili yonke into → #1 Holry 3.7 kW i-ER20 epholiswe ngamanzi.
Amaqoqo okukhiqiza, izingxenye zamathuluzi amaningi → #4 Holry 5.5 kW BT30 ATC.
Insimbi nemishini yangempela → #5 Holry 7.5 kW BT40.
akuwona Ama-spindle motors angcono kakhulu lawo ane-nameplate enkulu kakhulu. Yilabo ijika letorque, ukupholisa, kanye ne-taper ehambisana nalokho uhlaka lomshini wakho olungakusebenzisa. Ubukhulu be-spindle futhi uchitha imali bese udlidliza uhlaka. Ngaphansi kwayo futhi uzothenga futhi ezinyangeni eziyisithupha. Uma ungabaza, sithumelele ukuhamba komshini wakho, okokusebenza kohlaka, kanye nesigayo esivame kakhulu - sizokutshela ngokweqiniso ukuthi yimuphi usayizi okufanele uthenge, noma ngabe mncane kunalokho obukuthembile.
Indlela yokufaka engezansi iphinda inqubo yokuqala - ukugqekeza, ukushuna okuzenzakalelayo kwe-VFD, nokusika kokuqala - ukuze ungapheki i-spindle entsha ngosuku lokuqala.
Ikhithi ye-ER20 epholile engu-2.2 kW. Uzoyithola ebangeni lika-$350–$500 eline-VFD nama-collets. Gwema ama-sub-$200 'ama-spindles' - angamamotho enziwe kabusha anezilinganiso ze-nameplate ezingamanga.
Ngokupholisa okufanele, ukugcotshwa, kanye nokugqekezwa, i-spindle epholiswe ngamanzi igijima amahora angu-15,000-25,000. Amayunithi apholile emoyeni ahlala amahora angu-8,000–15,000 emsebenzini wokhuni. Amabhereyi ayimpahla egqokwayo - lindela ukupakisha kabusha noma ukukushintsha endaweni yamahora ayi-10,000.
Kufanele usebenzise i-VFD. Ama-spindle e-CNC asebenza ngamandla wezinga eliphezulu wezigaba ezintathu (200–400 Hz), hhayi amandla odonga angu-50/60 Hz. I-VFD ayizikhetheli — iyisilawuli semoto. Ikhithi ehambisanayo ye-VFD ihlala ishibhe kunokuthenga i-spindle ne-VFD ngokuhlukana.
Kuphela uma izingxenye zakho zidinga izinguquko zamathuluzi angu-3+. Ngomdwebo wethuluzi elilodwa noma ama-prototypes aphuma kanye, i-ER collet spindle ilula futhi ishibhile. Ngamaqoqo okukhiqiza, i-ATC izikhokhela yona enyangeni yokuqala.
