Indlela Inkqubo nganye eSebenza ngayo
Isitampu sesinyithi: Ukuguqulwa kwePlastiki phantsi koMmandla
Isitampu sesinyithi sisebenzisa umatshini wokushicilela kunye neseti yesiko lokufa ukuguqula isinyithi kwimilo ekujoliswe kuyo. Izinto eziphathekayo azisuswa-zifumana i- ngokutsha. I-hydraulic okanye umatshini wokushicilela usebenzisa i-5-1,000+ yeetoni zamandla ngokusebenzisa i-punch kwaye ifa ukuze igobe, ingenanto, ingqekembe, i-emboss, okanye i-deep-workpiece ye-workpiece nge-stroke enye okanye kwisikhululo sokufa esiqhubekayo.
Ukufa kwesitampu okuqhubekayo kunokuthwala izikhululo ezi-5-25 kwisixhobo esinye. Isitokhwe se-strip sondla ngokuzenzekelayo, kwaye isikhululo ngasinye senza umsebenzi omnye wokwenza. Inxalenye egqityiweyo inqunyulwa simahla kwisikhululo sokugqibela. Amaxesha okujikeleza nge-stroke: 0.5-2 imizuzwana. Oko kuthetha ukuba umshicileli omnye osebenza kwi-SPM ye-60 (i-strokes ngomzuzu) unokukhupha i-3,600 iinxalenye ezigqityiweyo ngeyure.
Iimpawu eziphambili:
-Inkqubo yokwenza-izinto eziphathekayo zeplastiki, azisuswanga.
- Izixhobo: intsimbi yesiko iyafa (isixhobo esinzima, i-D2, i-carbide inserts)
- Iindleko zesixhobo esiqhelekileyo: $ 5,000- $ 150,000 kuxhomekeke kubunzima
- Ixesha lomjikelo kwinxalenye nganye: 0.5-2 imizuzwana

I-CNC Machining: I-Subtractive Ukwenza
CNC machining iqala ngebhloko eqinileyo okanye ibha yentsimbi kwaye isuse izinto usebenzisa izixhobo zokusika ezijikelezayo. Isixhobo sokusila esilawulwa yikhompyutha okanye i-lathe ilandela indlela yesixhobo ecwangcisiweyo ukusika isitokhwe esingaphezulu, ukwenza ijometri egqityiweyo ngokulandelelana kokurhabaxa kunye nokugqiba.
Inxalenye nganye ifuna umjikelo opheleleyo womatshini-isixhobo sokusondela, ukusikwa, ukurhoxiswa, utshintsho lwesixhobo. Indawo yesibiyeli eqhelekileyo inokufuna iiseti ezi-3 ukuya kwezi-6, iinguqu ezisi-8–15 zesixhobo, kunye nemizuzu emi-3–8 yexesha lokusika iqhekeza ngalinye. Ukusetyenziswa kwezinto eziphathekayo kwi-CNC i-avareji ye-30-60% (ezinye ziba ziitshiphusi), ngelixa isitampu sifezekisa ukusetyenziswa kwe-70-90%.
Iimpawu eziphambili:
– Inkqubo yokuthabatha — imathiriyeli iyasikwa ukuze iveze imilo yokugqibela
- Izixhobo: i-standard end Mills, i-drills, ifaka (akukho siko sifa)
– Iindleko zesixhobo esiqhelekileyo: $0–$500 (inkqubo + yokulungisa)
- Ixesha lomjikelo kwinxalenye nganye: imizuzu eyi-1-30 ngokuxhomekeke kubunzima
-Ixesha lokuseta: 30–120 imizuzu kumdlalo ngamnye

I-crossover echanekileyo ixhomekeke kwinxalenye yejometri, iindleko zempahla, kunye nexesha elithile lokujikeleza kwe-CNC. Yibale ngokwahlula ixabiso lesixhobo sokutywina ngokomahluko weendleko zeyunithi nganye phakathi kwezi nkqubo zimbini.
Ngaba unokudibanisa isitampu sesinyithi kunye ne-CNC machining kwindawo enye?
Ewe. Indlela ye-hybrid-isitampu sejiyometri yobuninzi kunye nomatshini we-CNC-impawu zokunyamezela ezibalulekileyo-ziqhelekileyo kwiimoto, i-aerospace, kunye nokuveliswa kwezonyango. Oku kukunika inzuzo yeendleko zokutsibela kwi-80% yenxalenye ngelixa ubetha ± 0.001″ ukunyamezela ukuthwala iibhore, iigrooves zokutywina, okanye umphezulu onyukayo. Umsebenzi we-CNC wesibini ngokuqhelekileyo wongeza i-$ 1.50- $ 4.00 inxalenye nganye.
Yeyiphi inkqubo evelisa iindawo ezomeleleyo?
Akukho nkqubo inamandla ngokwemvelo-amandla axhomekeke ekukhethweni kwezinto kunye nonyango lokushisa. Nangona kunjalo, isiphumo sokusebenza kwesitampu sinokunyusa amandla esivuno kwiindawo ezenziweyo nge-10-30% xa kuthelekiswa nesitokhwe esifakiweyo. I-CNC machining isusa izinto ngaphandle kokutshintsha i-metallurgy eninzi. Kumalungu abalulekileyo okudinwa, iindawo ezinesitampu zinokuba luncedo ngenxa yokuqina komsebenzi, kodwa ugxininiso loxinzelelo kwi-bend radii kufuneka lubalwe kuyilo.
Ukunyamezelana kuthelekisa njani phakathi kwesitampu kunye ne-CNC machining? I-
CNC Machining ibamba unyamezelo ±0.001″ (±0.025 mm) ngokwesiqhelo kunye ±0.0005″ (±0.013 mm) ngokulungiswa ngononophelo. Isitampu esisemgangathweni sibamba i-±0.005″ (±0.13 mm), kunye nesitampu esichanekileyo esifumana ±0.002″ (±0.05 mm) kusetyenziswa i-ground dies kunye ne-in-die gauging. Ukuba inxalenye yakho ifuna unyamezelo olungqongqo kune ± 0.002 ″ kwiimpawu ezininzi, umatshini weCNC lolona khetho lungcono. Ukuba ±0.005″ kwamkelekile, isitampu sihambisa olo nyamezelo ngeqhezu lexabiso leyunithi nganye.
Ngowuphi ubungakanani obuncinane bomyalelo wokugximfizwa kwentsimbi ukwenza ingqiqo kwezoqoqosho?
Akukho MOQ ezinzileyo, kodwa uqoqosho luthanda ukunyathela ngaphezulu kwe-500–1,000 yeeyunithi kumalungu alula nangaphezulu kwe-2,000–5,000 yeeyunithi zeendawo ezintsonkothileyo zokufa. Ngaphantsi kwale miqulu, iindleko zezixhobo azinakuncitshiswa ngokwaneleyo. Ngobungakanani beprototype (i-1-50 iinxalenye), i-CNC machining okanye i-laser cutting + ukwenza ukhetho oluchanekileyo. Uninzi lwababoneleli besitampu, kubandakanywa Izahlulo zeMetal isitampu, inikezela ngemveliso yebhulorho kunye ne-laser-cut kunye neendawo ezibunjiweyo ngelixa i-ufa oqhubekayo tooling isenziwa.
Ukuqukumbela
Isitampu sesinyithi vs. Isigqibo somatshini weCNC sihla kwiinguqu ezintathu: umthamo, geometry, kunye iimfuno zonyamezelo. Ngaphezulu kwe-500-1,000 yeeyunithi ezinejometri eyenziwe yi-2D kunye nokunyamezela kwe-±0.005 ″ okanye i-looser, isitampu sinikezela nge-50-75% yokonga iindleko kwi-CNC kunye nemveliso ekhawulezayo yokuphuma. Ngaphantsi kwaloo volumu, okanye nge-3D yejometri entsonkothileyo efuna ±0.001″ ukunyamezela, i-CNC ngumnxeba ochanekileyo. Kwiindawo ezinomthamo ophezulu kunye neempawu ezimbalwa ezichanekileyo, indlela ye-hybrid-stampu umzimba, umatshini weempawu ezibalulekileyo-ukunika ezona zinto zibalaseleyo zehlabathi.
Ukuba uvavanya inxalenye yemveliso kwaye ufuna uthelekiso lweendleko phakathi kwesitampu kunye neCNC machining, Qhagamshelana neqela lethu lobunjineli kuhlalutyo lwasimahla lweDFM kunye nokucaphula. Siya kuqhuba amanani kwiimfuno zakho zejometri kunye nomthamo.
