Kutsiva Machined Bar Stock ne Investment Castings muHand Surgical Instruments

1. Iyo "yakagadzirwa-kubva-kubha" tsika mumaoko-zviridzwa

Maoko ekuvhiya zviridzwa akachekwa kubva 17-4 PH, 440C uye AISI 316 bar stock kubvira kare kusati kwaitwa mari yekukanda yaive yakakomba kugadzirwa kwezvikamu zvekurapa. Tsika yacho inoenderera nekuti:

• Bar stock ine inozivikanwa mechanical zvivakwa izvo mainjiniya anogadzika kutsanangura.
• 5-axis CNC michina inobata undercuts uye radii iyo ruoko-chiridzwa geometry inowanzoda.
• Bhara rimwe chete resimbi rinogona kuburitsa zvikamu zvakawanda pajeti ine ipfupi set-up.
• Zvipatara uye zvikwata zvekutenga zvinochengetedza nezvekugadzira-maitiro shanduko yezviridzwa zvinopinda mumuviri.

Tsika iyoyo zvino yave pasi pedzvinyiriro chaiyo. Iyo bar-stock nzira inorasa 60-80 % yezvinhu zvakatengwa semachipisi, inoda maminetsi makumi maviri kusvika makumi mana enguva yekutenderera pachikamu pamushini we5-axis, uye inogadzira maficha - senge akabatanidzwa grip nyere, mukati mechirimo rece, akawanda-axis claw maumbirwo - izvo zvinogoneka nemichina asi zvichirwadza muhupfumi. Sezvo vatengi vanotarisa kuderedzwa-mutengo weyuniti pamberi peiyo yepamusoro yeEuropean / US yevashandi nemitengo yesimba, nyaya yekushandura kuita yekuisa mari iri kuwedzera kujeka.

2. Iko kukanda mari kunohwina - mienzaniso mishanu yakajairika

3. Mitemo yekugadzira - chii chinoita kuti chiridzwa chikandwe

Iyo yekudyara-kukanda maitiro ine mitemo. Kana kudhirowa kwako kukavatyora, unovabhadharira muhupenyu hweforoma, mune zvakakandwa, kana mushure mekugadzira nguva inodzima kutenderera-nguva yekuchengetedza. Izvo zvinonyanya kukosha pazviridzwa zvemaoko:

• Ukobvu hwemadziro : chinangwa che 1.2 - 3.0 mm mayunifomu madziro. Pazasi 1.0 mm iwe unoisa pangozi misruns; pamusoro pe 4 mm iwe unobhadhara yakawedzera munguva yekukanda uye ungangoda kutonhora kwenguva refu kudzivirira shrinkage porosity.
• Radii : 1.0 mm zvishoma pamakona emukati. Makona akapinza anogadzira kunetsekana mune zvese kukanda uye chikamu chekupedzisira - ivo zvakare vanogadzira kushushikana kweiyo wax pateni uye kupfupisa mold hupenyu.
• Draft angles : 0.5–1.0° pazviso zvekudhirowa. Wakisi inofanira kubuda yakachena kubva mudhishi; kushivirira kwakasimba pakudhirowa ne zero dhizaini zvinoreva midziyo inodhura kana zvimedu.
• Texture : as-cast surfaces anotsvedzerera zvakakwana kune akawanda asiri ekubata maficha, asi kana dhizaini ichida knurling, inofanirwa kutsanangurwa seyakakandirwa-mukati mameseji, kwete post-machine knurl (zvikasadaro knurl inopera mu autoclave).
• Under-cuts : inogoneka mukukandira mari asi ivo vanosundira kuoma kwe mold uye per-piece wax inodhura. Usawedzera under-cuts kunze kwekunge dhizaini ichida ivo.
• Joint / Bearing bores : siya 0.4 - 0.6 mm machining allowance pane chero nzvimbo inoda kubatana kune imwe chikamu. Kukandira hakusi kutsiva kupedzisa-kubhowa pane chaiyo-inobereka nzvimbo.

Mutemo unoshanda wechigunwe kutumira kudhirowa kune yekutanga sezvaunokwanisa , kunyangwe dhizaini yako yemukati isati yaoma. Iyo DFM yemhinduro chikamu ndiyo yakachipa nzvimbo yekuwana shanduko diki dzinoshandura muganhu wakakandirwa kuita purofiti.

4. Kana KWETE kutendeutsa chikamu kune investimendi kukanda

Mamiriro mashoma apo shanduko yekukanda iri isiriyo kufamba:

• Vhoriyamu iri pazasi ~ 500 zvidimbu/gore : mutengo wemari yemidziyo haushande, uye maturusi ewakisi akadhindwa e3D anowanzo kudhura pachimedu pane machining bar pavhoriyamu iyoyo.
• Zvikamu zvidiki zvakasimba (pasi ~ 10 g) apo mitemo yemadziro-yakaoma zvakaoma kuteerera : mutyairi wetsono muviri, imwe-chidimbu scalpel blade. Machining bar anokunda pano.
• Single-axis rotational parts : a forceps screw pin, dental-scaler tip, reamer. Aya mabasa ekushandura; hapana chinowanikwa nekuwedzera danho rekukanda.
• Zvishandiso zvisina musoro kukanda muchitoro chedu : pure titanium implantable-giredhi, mamwe zirconia ceramics. Tinovanzvenga.
• Mutengi asingakwanisi kugamuchira "se-cast surfaces yakajairika" : kana mufananidzo wako uchitsanangura Ra 0.4 µm pachiso chega chega, haudi kukanda - unoda chikamu chakagadzirwa nemachini chaiwo. Zvikamu zvakakandwa zvinoda chirongwa chepamusoro chekurapa.

5. Mutengo / inotungamira-nguva masvomhu - maitiro ekufunga nezvazvo

Yakajairika ruoko-chiridzwa chekushandura chinotaridzika seizvi muna 2026:

• Tooling amortization yeSLA / 3D-yakadhindwa wakisi master uye aruminiyamu inofa: USD 5,000 - 15,000 pamusoro pe5,000-chidimbu-chipenga hupenyu. Kufa kwesimbi yakaoma (kazhinji ≥ 50,000-chidimbu vhoriyamu): USD 25,000 - 80,000.
• Chinyorwa chekutanga + FAIR : 6 - 9 mavhiki kubva kuPO.
• Serial piece price (mushure me5,000-piece run) : kazhinji yakaderera 30–50 % pane yakaenzana 5-axis machined-from-bar cost on the same feature set.
• Nguva yekutungamira pabatch (mushure mechinyorwa chekutanga) : 4 - 6 mavhiki e5,000-chidimbu batch, yakaderera pane-chidimbu pane bhari rakagadzirwa.

Nhamba idzi dzinochinja zvakanyanya nemutengo we-raw-material. Kana 17-4 PH bar ikadhura zvisingaite, nyaya yekukanda inosimba.

6. FAQ

Mubvunzo: Kukandira kwekudyara kunoshandura hunhu hwesimbi ye17-4 PH yakabatana kana ichienzaniswa nebhawa stock? A: Ehe - uye kazhinji munzira yaunoda. Investment-cast 17-4 PH ine yakatsetseka, yakawanda yunifomu tsanga pane hombe-diameter bar, iyo inovandudza kuneta kuita uye inopa kuomarara kusingachinji mushure mekupisa kurapwa. Kemisitiri haichinji; iyo microstructure inoita.

Mubvunzo: Ndinogona kuchengeta dhirowa rangu uye kungowana chikamu chakafanana chakakandwa? A: Dzimwe nguva hongu, asi kazhinji kwete. Investment castings inobatsirwa kubva kudiki kudhirowa zvigadziriso (radii, dhizaini, ukobvu hwemadziro) kuchengetedza maturusi mutengo unonzwisisika uye chirairo mwero wakaderera. Wongororo yeDFM chikamu chechikamu chega chega chatinokora.

Mubvunzo: Kukandira kunoshanda kune mabheti madiki (taura zviridzwa mazana maviri)? A: Kune prototypes, hongu - 3D-yakadhindwa wakisi chishandiso inoita kuti itengeke. Kuti urambe uchigadzira, kukanda kunowanzoda ≥ 500-1,000 zvidimbu / gore kuti ubvise chishandiso.

Mubvunzo: Zvakadini nezve hypo-tubing uye mamwe akanyanya-chaiyo akatetepa-madziro asina tsvina zvikamu? A: Investment casting kazhinji haisi iyo nzira yakakodzera kune dzakatetepa-madziro chubhu-sezvikamu; laser welding, hydro-forming kana machining kubva chubhu kazhinji zviri nani. Tichakuudza kana chikamu chisina kukodzera kukanda panguva yekuongorora kweDFM.

Mubvunzo: Kupera kwepamusoro kuchave kwakasiyana kubva kumachine bar stock? A: Hongu - nzvimbo yekukanda ine hunhu hwakatsetseka-zviyo magadzirirwo. Kune nzvimbo dzinoshanda (dzinotakura zvigaro, zviso zveshaya) isu tinogadzira izvo zvimiro zvakadaro. Kune aesthetic nzvimbo isu tinopa electropolishing uye passivation inounza pasi pasi kuRa ≤ 0.4 µm.

7. Mhedziso

Kutsiva michini yebhaa stock nekukandwa kwekudyara idanho rakangwara reakaomesesa ruoko-chiridzwa geometri mune batch saizi kubva 1,000 zvidimbu zvichikwira - inocheka nguva yekutenderera, mbishi-chigadzirwa mutengo uye chishandiso-kuchinja pamusoro munhanho imwe. Kune akareruka kutenderera zvikamu kana sub-500-chidimbu mavhoriyamu epagore, bhaa yemuchina ichiri mhinduro chaiyo, uye yakakomba foundry ichakuudza izvozvo. KuNingbo Ruican tinomhanya 17+ makore ekudzidzira pakurapa 17-4 PH uye AISI 316L castings, ne-mu-house kupisa kurapwa uye CNC kupedza.
