Hababka daaweynta dusha sare ee qaybaha mashiinka CNC

Warshadaha wax soo saarka prototyping ee degdega ah, daawaynta dusha kala duwan ayaa la isticmaalaa. Daawaynta dusha sare waxa loola jeedaa samaynta lakab leh hal ama in ka badan oo sifo gaar ah ku leh dusha shay iyada oo loo marayo hab jidheed ama kiimiko. Daaweynta dusha sare waxay hagaajin kartaa muuqaalka, xirashada caabbinta, caabbinta daxalka, adkaanta, xoogga iyo sifooyinka kale ee alaabta.

1. Dusha mashiinada caadiga ah

Sagxadaha la farsameeyay ayaa ah daawaynta dusha caadiga ah. Dusha sare ee qaybta la sameeyay ka dib marka la dhammeeyo mashiinnada CNC waxay yeelan doontaa khadadka wax-qabadka ee cad, iyo qiimaha qallafsanaanta dusha sare waa Ra0.2-Ra3.2. Caadi ahaan waxaa jira daawayn dusha sare ah sida ka saarista cidhifyada iyo cidhifyada fiiqan. Dushani waxay ku habboon tahay dhammaan alaabta.

2. Ciid-qarxinta

Habka nadiifinta iyo qallafsanaanta dusha sare ee substrate iyadoo la adeegsanayo saameynta socodka ciid-xawaaraha sare wuxuu u ogolaanayaa dusha sare ee workpiece si uu u helo shahaado gaar ah oo nadiif ah iyo qallafsanaan kala duwan, taas oo hagaajinaysa sifooyinka farsamada ee dusha sare ee workpiece, taas oo hagaajinaysa caabbinta daalka ee workpiece iyo kordhinta adhesion u dhexeeya iyada iyo daahan ayaa kordhiya cimri dhererka filimka daahan iyo sidoo kale faa'iido u leh dahaarka heerka.

2. Daalid

Habka korantada kiimikaad wuxuu nadiifiyaa qaybaha birta isagoo ka dhigaya birta dhalaalaysa si loo yareeyo daxalka iyo hagaajinta muuqaalka. Waxay saartaa qiyaastii 0.0001"-0.0025" birta ah. U hoggaansan ASTM B912-02.

4. anodizing caadiga ah

Si looga gudbo cilladaha ku jira engegnaanta dusha aluminium aluminium iyo xidhashada caabbinta, ballaarinta baaxadda codsiga, iyo kordhinta nolosha adeegga, tignoolajiyada anodizing waa tan ugu ballaaran ee loo isticmaalo oo lagu guuleysto. Cad, madow, casaan iyo dahab ayaa ah midabada ugu caansan, oo inta badan la xidhiidha aluminium. (Fiiro gaar ah: Waxaa jiri doona farqi midab gaar ah oo u dhexeeya midabka dhabta ah ka dib anodization iyo midabka sawirka.)

5. Adag anodized

Dhumucda oksaydheynta adag ayaa ka dhumuc weyn kan oksaydhka caadiga ah. Guud ahaan, dhumucda filimka caadiga ah ee oksaydhka waa 8-12UM, dhumucda filimka adag ee oksaydhka guud ahaan waa 40-70UM. Adag: oksaydhaynta caadiga ah guud ahaan HV250--350

Oxysaydhka adag guud ahaan waa HV350--550. Kordhinta dahaarka, adkaysiga xidhashada oo kordhay, iska caabinta daxalka oo kordhay, iwm. Laakiin qiimuhu sidoo kale wuu kordhin doonaa.

6. Buufi rinjiyeynta

Dahaarka loo isticmaalo dusha sare ee biraha workpieces si ay u qurxiyaan oo loo ilaaliyo biraha dusha. Waxay si gaar ah ugu habboon tahay qalabka birta ah ee cufan sida aluminium, alloys, iyo birta aan lahayn. Waxa si weyn loogu isticmaalaa sidii varnish-ka-ku-samaynta dusha sare ee qalabka qalabka korontada ku shaqeeya sida laambadaha, qalabka guriga, sagxadaha birta, iyo farsamada biraha. Waxa kale oo loo isticmaali karaa sidii rinjiga qurxinta ee ilaalinta baabuurta, qalabka mootooyinka, haamaha shidaalka, iwm.

7.Matt

Isticmaal qaybo ciid ah oo xoqan si aad ugu xoqdo dusha sare ee alaabta si aad u soo saarto milicsi fidsan iyo saameyn aan toos ahayn. Noocyada kala duwan ee jajabka ah ayaa lagu dhejiyaa dhabarka warqadda daboolka ah ama kartoonada, iyo cabbirrada kala duwan ee hadhuudhka ayaa lagu kala saari karaa iyada oo loo eegayo cabbirkooda: xajmiga weyn ee hadhuudhka, miraha jilicsan ee jilicsan, iyo saameynta dusha sare ee wanaagsan.

8.Dareenka

Habka loo beddelo dusha birta oo loo beddelo xaalad aan u nuglayn oksaydhisku oo hoos u dhigaya heerka daxalka ee birta.

9.Galvanized

Dahaarka zinc galvanized ee birta ama birta si looga hortago miridhku. Habka ugu badan ee la isticmaalo ayaa ah galvanized-kuleyl, oo qaybo gelinaya jeexdin zinc kulul ee dhalaalaysa.
