1. Isiko elithi "omshini-kusuka-kwibha" kumathuluzi esandla
Amathuluzi okuhlinza ngesandla anqanyuliwe kusuka ku-17-4 PH, 440C kanye nesitoko sebha se-AISI 316 kusukela kudala ngaphambi kokutshala imali kube inqubo ebucayi yokukhiqiza izingxenye zezokwelapha. Isiko liyaqhubeka ngoba:
- Isitoko sebha sinezakhiwo ezaziwayo zemishini onjiniyela abakhululekile ukuzicacisa.
- Imishini ye-CNC ye-axis engu-5 iphatha ama-undercuts nama-radii ijiyomethri yesisetshenziswa sesandla esivame ukuyidinga.
- Ibha eyodwa yensimbi ingakhiqiza izingxenye eziningi kwilotho ngayinye ngokusetha okufushane.
- Izibhedlela namathimba okuthengwa kwempahla ayacophelela mayelana nezinguquko zenqubo yokukhiqiza yamathuluzi angena emzimbeni.
Lelo siko manje selingaphansi kwengcindezi yangempela. Indlela ye-bar-stock imosha u-60-80 % wezinto ezithengiwe njengama-chips, idinga imizuzu engu-20-40 yesikhathi sokujikeleza ingxenye ngayinye emshinini wama-axis angu-5, futhi ikhiqiza izici - njengemitshingo yokubamba ebalulekile, amakhefu angaphakathi entwasahlobo, ukubunjwa kwe-claw ye-multi-axis - okungenzeka ngokomshini kodwa okubuhlungu ngokwezomnotho. Njengoba abathengi bebheka ukwehliswa kwezindleko zeyunithi lapho bebhekene nezindleko eziphezulu zabasebenzi kanye namandla e-Europe/US, icala lokuguqulela ekutshalweni kwezimali liya licaca.

3. Imithetho yedizayini — yini eyenza insimbi isebenze
Inqubo yokutshala imali inemithetho. Uma umdwebo wakho uziphula, uzikhokhela empilweni yesikhunta, nge-cast scrap, noma ngesikhathi sangemuva komshini esisula ukonga kwesikhathi somjikelezo. Okubaluleke kakhulu kumathuluzi esandla:
- Ukujiya kodonga : hlose ukuba nezindonga ezifanayo eziyi-1.2 – 3.0 mm. Ngaphansi kuka-1.0 mm uzibeka engcupheni yokungahambi kahle; ngaphezu kuka-4 mm ukhokha imali eyengeziwe ngesikhathi sokuphonsa futhi ungase udinge ukupholisa isikhathi eside ukuze ugweme ukushwabana kwe-porosity.
- I-Radii : 1.0 mm ubuncane emakhoneni angaphakathi. Amakhona acijile adala ukugxila kwengcindezi kukho kokubili ukusakaza kanye nengxenye yokugcina - futhi adala ukugxila kwengcindezi kuphethini ye-wax futhi afinyeze impilo yesikhunta.
- Ama-engeli asalungiswa : 0.5–1.0° ebusweni bokudonsa. I-wax kufanele iphume ihlanzekile efashini; ukubekezelela okuqinile emdwebeni ongasalungiswanga ziro kusho amathuluzi abizayo noma izilahlwa.
- Ukuthungwa : izindawo ezisakazwayo zibushelelezi ngokwanele ezicini eziningi ezingezona izibambi, kodwa uma idizayini idinga ukugoqa, kufanele icaciswe njengokuthungwa kwe-cast-in, hhayi i-post-machined knurl (ngaphandle kwalokho i-knurl iyaguga ku-autoclave).
- I-under-cuts : iyenzeka ekufakweni kwe-investimenti kodwa icindezela ubunkimbinkimbi besikhunta kanye nocezu ngalunye lwe-wax kubiza. Ungangezi ama-under-cut ngaphandle uma idizayini iwadinga.
- Izibhobo ezihlangene / ezithwalayo : shiya isibonelelo sika-0.4 – 0.6 mm somshini kunoma iyiphi indawo edinga ukuhlangana kwenye ingxenye. Ukusakaza akuthathi indawo yokuqeda isicefe endaweni ephethe ukunemba.
Umthetho osebenzayo wesithupha uwukuthumela umdwebo endaweni yokusungula ngokushesha ngangokunokwenzeka , nangaphambi kokuba umklamo wakho wangaphakathi uqine. Iseshini yempendulo ye-DFM iyindawo eshibhe kakhulu yokuthola izinguquko ezincane ezishintsha ukukhishwa kwe-marginal kube okunenzuzo.
4. Lapho AKUFANELE uguqule ingxenye ibe ukusakaza kokutshalwa kwezimali
Izimo ezimbalwa lapho ukuguqulwa kokusakaza kuyisinyathelo esingalungile:
- Ivolumu engezansi ~izingcezu ezingu-500/ngonyaka : ukuncishiswa kwezindleko zamathuluzi akusebenzi, futhi amathuluzi we-wax aphrintiwe nge-3D ngokuvamile abiza kakhulu ucezu ngalunye kunebha yokwenza imishini kuleyo volumu.
- Izingxenye eziqinile ezincane (ngaphansi kuka-~10 g) lapho imithetho yokuqina kodonga okunzima ukuyilalela : umzimba oshayelwa inaliti, i-scalpel blade yesiqephu esisodwa. Ibha yomshini iyawina lapha.
- Izingxenye ezijikelezayo ze-axis eyodwa : iphinikhodi yesikulufu se-forceps, ithiphu yesikali samazinyo, i-reamer. Lena yimisebenzi eshintshayo; akukho lutho oluzuzwayo ngokwengeza isinyathelo sokuphonsa.
- Izinto ezingenangqondo zokusakaza esitolo sethu : Ibanga elihlanzekile le-titanium elifakekayo, izitsha ezithile zobumba ze-zirconia. Siyabagwema.
- Umthengi ongakwazi ukwamukela "indawo esakazwayo ijwayelekile" : uma umdwebo wakho ucacisa u-Ra 0.4 µm kubo bonke ubuso, awufuni ukusakaza — ufuna ingxenye eyenziwe ngomshini onembile. Izingxenye zabalingisi zidinga uhlelo lokwelapha phezulu.
5. Izindleko / i-lead-time izibalo - indlela yokucabanga ngayo
Ukuguqulwa okujwayelekile kwensimbi yesandla kubonakala kanje ngo-2026:
- I-amortization yamathuluzi ye-SLA / 3D-printed wax master kanye ne-aluminium die: USD 5,000 – 15,000 phezu kwempilo yamathuluzi yezingcezu ezingu-5,000. Okokufa kwensimbi eqinile (imvamisa engu-≥ 50,000-piece volume): USD 25,000 - 80,000.
- Isihloko sokuqala + FAIR : 6 – 9 amaviki ukusuka ku-PO.
- Intengo ye-serial piece (ngemuva kokugijima kweziqephu ezingu-5,000) : ngokuvamile ingaphansi ngo-30–50 % kunezindleko ezilinganayo zama-axis angu-5 omshini-kusuka kubha kusethi yesici esifanayo.
- Isikhathi sokuhola ngeqeqebana ngalinye (ngemuva kwesihloko sokuqala) : Amaviki angu-4 – 6 ngenqwaba yeziqephu ezingu-5,000, aphansi ngocezu ngalunye kunebha emshinini.
Lezi zinombolo zishintsha kakhulu ngezindleko zezinto ezingavuthiwe. Uma ibha engu-17-4 PH ibiza ngokungavamile, ikesi lokusakaza liba namandla.
