Uma abantu abaningi bezwa 'ukunemba komshini,' bafanekisa ishidi le-spec elicwebezelayo elinokubekezelela okuqinile njengo-±0.005mm. Leyo yingxenye yakho, impela, kodwa esitolo, isilwane esiphilayo, esiphefumulayo. Igebe phakathi kwalokho okufunwa imodeli ye-CAD kanye nalokho umshini, ithuluzi, impahla, futhi ngokungananazi, ulwazi lomsebenzisi ngalolo Lwesibili ekuseni lungaletha ngempela. Amakhasimende amaningi, ikakhulukazi lawo amasha ezingxenyeni zokuthola usizo, alengiswe kuleyo nombolo ngaphandle kokuqonda i-ecosystem edingekayo ukuze ayifinyelele ngokuqhubekayo. Bazocela ukubekezelelana okuphambene endlini enkulu yensimbi, bengaqapheli amandla okushisa kanye nokukhululeka kwengcindezi engxenyeni ngokwayo kuzokulwa nawe ngaso sonke isikhathi. Kulapho umsebenzi wangempela uqala khona.
Isisekelo: Iqala Ngaphambi Kokuba Umshini Ngisho Uphonswe
Awukwazi ukukhuluma ngokunemba kwemishini ngaphandle kokuthi uqale ukhulume ngalokho okwenzayo. Intaba engizofela kuyona. Ngibone amaphrojekthi amaningi kakhulu eya eceleni ngoba impahla engenayo noma ukusakaza kuthathwe njengokucatshangelwa kamuva. Ngokwesibonelo, sisebenza njalo I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Umlando wabo omude egobolondweni nasekutshalweni kwezimali ubalulekile. Lapho behlinzeka nge-nickel-based alloy investment casting engxenyeni ye-turbine, ukungaguquguquki kwaleyo ngxenye eluhlaza-umsindo wayo wangaphakathi, ingcindezi encane eyinsalela, kanye ne-metallurgy ebikezelwayo - kusetha uphahla ukunemba komshini singazuza kamuva. Uma ukusakaza kunokuqina okufihliwe noma ukujiya kodonga okungahambisani, alikho inani lohlelo lwe-CNC oluphambili oluzokusindisa. Awenzi i-billet ephelele; uzulazula endaweni eyakhiwe ngaphambilini. Ubambiswano, ukwazi inqubo yabo ku https://www.tsingtaocnc.com igxile kulawa ma-alloys akhethekile, kusho ukuthi siqala kwesisekelo esaziwayo, esizinzile. Leyo ingxenye yempi enqotshiwe ngaphambi kokuthi kuklanywe umdlalo wokuqala.
Inkumbulo yezinto ezibonakalayo ingomunye umbulali othule. Thatha insimbi engagqwali. Kudume kabi ngokuhamba ngesikhathi nangemva komshini njengoba izingcindezi zangaphakathi zikhishwa isenzo sokusika. Ungase ubambe ukubekezelelana okungu-±0.01mm ngesikhathi se-op yokuqala, uthole ukuthi ingxenye igxumeke ngaphezu kokuhlengwa ngemva kokuhlala ubusuku bonke. Ukunemba lapha akukhona nje mayelana nokuphindaphinda komshini; imayelana nomklamo wenqubo. Kwesinye isikhathi, kufanele uyikhahlameze, uyiyeke ihlale, ikhulule ingcindezi, bese ubuya uzoqeda. Ihamba kancane, ayibukhazikhazi, futhi awukwazi ukukhokhisa isikhathi sokulinda ngendlela eqondile, kodwa iyona ndlela kuphela yokuthola ukunemba kwangempela, okuzinzile. Ukweqa leso sinyathelo kuwukwakha nje ukwehluleka okuzayo.
I-Fixture design iwubuciko bayo obumnyama. Ngomsebenzi wokunemba okuphezulu, i-fixture ayigcini nje ngokubamba ingxenye; iba yingxenye yochungechunge lwe-kinematic. Ulwa namandla okubamba angahlanekezela izindonga ezincanyana, ukunwetshwa okushisayo kusuka kokubili ingxenye kanye nokokusebenza kokulungisa, nokuqinisekisa ukuphindaphinda kwendawo kuyo yonke inqwaba. Ngikhumbula umsebenzi wokwenza izici eziyinkimbinkimbi ku-cobalt-based alloy seal enikezwe uzakwethu onjenge-QSY. Ingxenye yayiyiphupho elibi ukuyibamba ngaphandle kokuhlanekezela.
