Mukamva 'special alloy insert', chithunzi chomwe chilipo nthawi zambiri chimakhala chonyezimira, chosawonongeka cha zida zolimba. Izi sizolakwika, koma ndi poyambira zomwe zimasokoneza zisankho zenizeni, zopanda pake. Chowonadi ndi chakuti, kusankha ndi kugwiritsa ntchito zoyika izi ndizochepa pa kusankha njira 'yovuta kwambiri' komanso zambiri zokhudzana ndi kuyendetsa malonda ovuta pakati pa kukana kuvala, kulimba, kukhazikika kwa kutentha, ndi khalidwe lachindunji, lomwe nthawi zambiri silingadziwike, la workpiece. Ndawonapo mapulojekiti ambiri akuyimitsidwa chifukwa wina adangoyitanitsa choyikapo chokwera mtengo kwambiri cha cobalt, poganiza kuti chinali chipolopolo chamatsenga, ndikungoyang'anizana ndi kugunda kowopsa pakudulidwa koyamba komwe kunasokonezedwa pakuponyedwa kwa nickel-based alloy. Sayansi yakuthupi ndiyofunikira, koma kugwiritsa ntchito bwino ndi komwe chidziwitso chenicheni chimakhala.
Kupitilira Kabukuko: Kufananiza Zinthu Ndi Chilichonse
Tiyeni tikambirane za aloyi okha. Kugwira ntchito ndi poyambira ndi makina ogulitsa ngati QSY, mumapeza mpando wakutsogolo kwa moyo wonse. Sitimangopanga makina apadera a aloyi; timawaponya. Kachitidwe kameneka—kaya ndi nkhungu ya chipolopolo kapena kuyika ndalama—imapereka makhalidwe enaake mu zinthuzo. Aloyi yopangidwa ndi nickel ngati Inconel 718 molunjika kuchokera ku njira yopangira ndalama imatha kukhala ndi chimanga chosiyana ndi mbiri yotsalira yotsalira poyerekeza ndi katundu wopangidwa. Kusiyanasiyana kumeneku ndikofunikira kwambiri pakusankha zoyika.
Vuto lodziwika bwino ndikusamalira ma aloyi onse opangidwa ndi faifi tambala ngati chipika cha monolithic. Choyikapo chokhala ndi nsonga yakuthwa ndi zokutira zopyapyala za PVD zitha kugwira ntchito bwino pakuwumbidwa kosasintha, kosalala bwino kwa gawo la vavu. Yesaninso choyikapo chomwechi pamakina akulu, ovuta kuyika makoma amitundu yosiyanasiyana komanso kuthekera kokhala ndi mawanga olimba kapena ophatikizika, ndipo mukhala mukusintha m'mphepete mphindi khumi zilizonse. Choyikapo chiyenera kuyamwa kugwedezeka, osati kungokana kuphulika. Nthawi zina, giredi 'yofewa' pang'ono koma yolimba kwambiri yokhala ndi chipbreaker geometry yolimba imapambana njira yolimba kwambiri, yosasinthika yomwe bukhu lingafotokozere.
Apa ndipamene zaka 30 zakumbuyo pamalo ngati QSY zimawonekera. Sikuti ali ndi makina CNC; ndi chidziwitso chozikika m'mene mapangidwe awo amachitira pansi pa chida. Awona kuti ndi magulu ati a aloyi omwe amapangidwa ndi cobalt omwe amawotcha kwambiri, kapena ndi magulu ati azitsulo zosapanga dzimbiri kuchokera pamaziko awo omwe ali ndi mgwirizano wina womanga. Chidziwitso chamkati chamkati pakati pa kuponyera ndi makina chimadziwitsa kusankha koyika m'njira yomwe palibe kalozera wothandizira.
Geometry ndi Coating Dance
Chabwino, ndiye kuti mwafananiza gawo la gawolo ndi umunthu wa chogwiriracho. Kenako pakubwera geometry. Ndikukumbukira ntchito yokonza njira zingapo zakuya, zopapatiza mu nyumba yapampopi yachitsulo chosapanga dzimbiri. Tinali ndi giredi yoyenera — carbide yolimba yoyenerera zosapanga dzimbiri. Koma mawonekedwe a diamondi a digirii 80 anali kuchititsa kugwedezeka koyipa komanso kusamuka bwino kwa chip. Mbaliyo inali kudziguguda mpaka kufa.
Tinasinthira ku chozungulira cholowetsa. Kugawa kwa mphamvu yodula kunasintha kwathunthu. Palibenso kukweza mfundo imodzi, kudula kosavuta. Kusinthanitsa? Kuyika kozungulira sikungathe kuchita ngodya zakuthwa. Tinayenera kukonzanso njira yachida cha radii, ndikuwonjezera gawo lowonjezera la mphero pamakona. Kunali kugonja, koma kunathandiza. The takeaway: mawonekedwe a chophatikizira chapadera cha alloy sikutanthauza kudulidwa kokha, koma mwina njira yonse yopangira makina komanso kulekerera kwa gawo.
Ndiye pali zokutira. TiAlN, AlTiN, carbon ngati diamondi... ndi msuzi wa zilembo. Ulamuliro wa chala chachikulu ndikuti zokutira ngati AlTiN kumapereka kuuma kotentha kwambiri, komwe kumakhala koyenera kutentha kwambiri komwe kumapangidwa potembenuza kapena mphero ma aloyi a nickel. Koma ngati njira yanu siyili yokhazikika, ngati muli ndi kusokoneza koziziritsa kapena chakudya chosagwirizana, zokutira zomwezi zitha kung'ambika pang'onopang'ono panjinga yotentha. Pakudulira kwina kosokonekera pamagawo oyikapo ndalama okhala ndi zipata kapena zokwera zokwera, carbide yosakutidwa koma yolimba kwambiri ingakhale kubetcha kotetezeka, kodziwikiratu, ngakhale moyo wake wakuvalira utakhala wotsika. Mukuika patsogolo kudalirika kwazinthu kuposa moyo wa zida.
Zolephera Zenizeni Zapadziko Lonse ndi Zosintha
Ndigawana zolephera zomwe zidandiphunzitsa kupambana kopitilira khumi ndi awiri. Tinkawononga chipika chachikulu cha Monel (chopangidwa ndi nickel-copper alloy) kuti tigwiritse ntchito panyanja. Kujambula kuchokera ku maziko athu kunali komveka, koma kwakukulu. Tinkagwiritsa ntchito chodula chapamwamba kwambiri, choduliridwa ndi chitoliro chodzipatulira chophatikizira chapadera cha alloys adapangidwira ma alloys otentha kwambiri. Chiphunzitsocho chinali changwiro: kuchepetsa mphamvu yodula, kuchepetsa kutentha kwa gawolo.
Izo zinalephera. Osati modabwitsa, koma mobisa. Zoyikapo sizinaphwanyike kapena kusweka. Iwo anangowonongeka, mofanana ndi mofulumira, pa nkhope ya m'mbali. Vutolo? Ma geometry abwino kwambiri, pomwe amachepetsa mphamvu, adapanganso mphero yocheperako, yocheperako. The Monel, ndi chizolowezi chake chowumitsa ntchito komanso tchipisi ta zingwe, inali kuphwanya mbali yake mwachangu kwambiri. Tinali kupanga tchipisi zokongola, zonyezimira koma kupha chida.
Kukonzekera kunali kotsutsa. Tinapita kumalo osalowerera ndale, amphamvu oyikapo ma geometry ndi kukonzekera kolemera m'mphepete (m'mphepete mwabwino, osati lakuthwa). Izi zidawonjezera mphamvu yodulira pang'ono, koma idathandizira kudulidwa bwino kwambiri motsutsana ndi abrasion. Chipcho chinali chokhuthala, chopanda zingwe, ndipo chimanyamula kutentha bwino. Chida moyo wawirikiza katatu. Phunziro: mu ma aloyi a nickel apamwamba, nthawi zina mumayenera kutsamira pa odulidwawo ndi m'mphepete mwamphamvu, osayesa kutsetsereka ndi wosakhwima.
Zozizira: Bwenzi Kapena Mdani mu Special Alloy Machining?
Izi ndi zotsutsana. Langizo lachikale la makina a titaniyamu ndi ma aloyi a nickel ndi ozizira madzi osefukira, nthawi zonse. Ndipo pamachitidwe ambiri, ndikolondola - imayang'anira kutentha kwina ndikuthandizira kuchotsa chip. Koma ndi izi chophatikizira chapadera cha alloys, makamaka omwe ali ndi magiredi ena a ceramic kapena CBN (cubic boron nitride), kugwedezeka kwamafuta ndikupha kwenikweni.
Tangoganizani kuti mukuyika choyikapo cha ceramic pazitsulo zowuma. Choyikacho chimagwira ntchito m'dera la kutentha kwambiri pamphepete; umo ndi momwe zimakhalira kuuma kwake. Ngati jeti ya choziziritsira m'chipinda chozizira igunda m'mphepete mofiyira pang'onopang'ono, mukupempha ming'alu yaying'ono. Zikatero, mutha kusankha kuphulika kwa mpweya, kapena bwinoko, makina othamanga kwambiri omwe amapereka kuziziritsa ndi kutulutsa chip popanda kusiyana kwakukulu kwa kutentha kwa madzi ozizira.
Pazoyika zodziwika bwino za carbide zokhala ndi zokutira za PVD pa cobalt kapena ma aloyi opangidwa ndi faifi, zoziziritsa kukhosi zodutsa pazida nthawi zambiri zimakhala mfumu. Sikuti kuziziritsa kokha; ndi za kutulutsa tchipisi taukali, zonyansa kuchokera pamalo odulidwa nthawi yomweyo. Chip recut ndi kulephera kuyika kotsimikizika. Pamalo awo opangira makina a CNC, kupeza zoziziritsa kukhosi zodalirika kwambiri pamalo odulidwa enieni ndi njira yokhazikitsira yosakanizika kuti igwire bwino ntchito ya alloy yapadera.
Supply Chain ndi Practical Sourcing
Nazi zina zomwe simungazipeze mu pepala laukadaulo: zenizeni zenizeni. Zoyika izi ndizokwera mtengo. Kusunga zinthu zonse zomwe zingatheke ndikugwira ntchito ndi gawo lalikulu la malo ogulitsa ntchito. Ubale ndi wogulitsa amene amamvetsetsa kusakaniza kwanu kwa ntchito-monga chitsulo choponyedwa, chosapanga dzimbiri, ndi ma aloyi apadera omwe QSY imagwira-ndiwovuta.
Sizokhudza kukhala ndi mitundu yambiri, koma kukhala ndi mizere yodalirika yocheperako komwe mumamvetsetsa bwino envulopu yantchito. Mukumva kuti Gulu la XXX kuchokera kwa omwe akukugulirani ndizomwe mungapiteko pa 90% ya ntchito yanu yosapanga dzimbiri ya 17-4PH kuchokera pamzere wopangira ndalama, ndipo Gulu la YYY lasungidwira mabala omwe asokonekera kwambiri pamatupi akuluakulu a Inconel 625. Mumamanga laibulale yamalingaliro - kenako laibulale yakuthupi - zomwe zimathandizira zovuta zomwe shopu yanu imakumana nazo.
Apanso ndipamene ntchito yophatikizika yokhazikika imawonetsa mphamvu zake. Chifukwa chakuti amawongolera njira yoponyera, nthawi zina amatha kusintha chithandizo cha kutentha kapena ngakhale kupanga mapangidwe (kuwonjezera utali wochepa, kusintha makulidwe a khoma) kuti gawolo likhale lopangidwa ndi makina ovomerezeka, odalirika omwe ali nawo kale. Kuti mgwirizano wamkati pakati pa foundry ndi shopu yamakina kuti muwongolere pakupanga ndi mwayi waukulu, womwe nthawi zambiri umabisika, womwe umakhudza mwachindunji kugwiritsa ntchito zida zodulira mwatsatanetsatane.
Kotero, nthawi ina mukamatchula a chophatikizira chapadera cha alloy, yang'anani kupyola pa datasheet. Ganizirani mbiri ya gawolo (lopangidwa kapena lopangidwa?), geometry yake (yodulidwa yoduliridwa kapena mosalekeza?), Kulimba kwa makina anu, ndi njira yanu yozizira. Ndi dongosolo, ndipo choyikapo ndi gawo limodzi lofunikira. Kuwongolera kumamveka ngati sayansi komanso ngati luso laukadaulo, luso lopangidwa chifukwa cha zolephera zomwe mwawona, kusintha kosawoneka bwino, komanso kulemekeza kwambiri zinthu zomwe mukuyesera kuziwongolera.
