Impembelelo yokusika ubushushu
Xa ukugaya i-alloys esekelwe kwi-nickel, ubungakanani obukhulu bokusika ubushushu buveliswa. Ngoko ke, xa umatshini, sebenzisa i-coolant eyaneleyo yokuntywilisela indawo yokusika, ekulula ukuyifezekisa kubasiki be-milling-diameter encinci, kodwa kwizixhobo zobubanzi obukhulu (ezifana ne-face milling cutters), akunakwenzeka ukucwiliswa ngokupheleleyo ngexesha lokusika, kwaye Isipholisi sinokucinywa kuphela , kusetyenziswa ukungqusha okomileyo.
Xa i-cutter yokugaya ayinakugqunywa yi-coolant, ukushisa kudluliselwa ngokukhawuleza kwaye kufakwe kwi-insert, okubangela ukuba kubekho iintanda ezininzi ezincinci kwi-cutting edge, kunye nokuqhekeka kwanda ngokuthe ngcembe, ekugqibeleni kubangela ukuba i-carbide ene-cemented iphule. Kwezinye iimeko, i-cutter encinci yokusila ingasetyenziswa, kwaye akukho nto yokupholisa efunekayo ekwenzeni imishini. Ukuba isixhobo sisika ngokuqhelekileyo kwaye ubomi besixhobo buphuculwe, oko kuthetha ukuba ukugaya okomileyo okusebenzayo nako kunokwenziwa.
Ngenxa yokuba iinxalenye kwimizi-mveliso yezonyango kunye ne-aerospace zihlala zenziwe ngama-alloys asekelwe kwi-nickel, le nto idla ngokuhamba kunye namaxwebhu esatifikethi, apho i-chemical structure yale nto ikhethekileyo inikwe, ukuze sikwazi ukwazi xa ukugaya . yintoni impahla. Yintoni ekufuneka ihlawulwe ingqalelo yindlela yokukhetha iiparitha ezifanelekileyo zokusika kunye neendlela zokusika ngokumalunga nokubunjwa kwezinto ezinjalo.
Njengoko bekutshiwo ngaphambili, izinto ezimbini eziphambili zeli qela lesinyithi ziyi-nickel kunye ne-chromium. Xa i-smelter yesinyithi ilungisa umxholo wepesenti yetsimbi nganye, iimpawu zayo ezifana nokuchasana nokubola, amandla, ubunzima, njl.
Ukuyila isixhobo sokusika i-workpieces enzima okanye enzima akunzima, kodwa ukuyila i-nickel-based alloy tool eyenza zombini akunjalo. Unokuba nelakho igama lezi ngxubevange, kodwa okoko usazi ukubunjwa kwazo kwaye usebenzise isixhobo esifanelekileyo, unokusila izinto ezifana neCor20, Rene41, kunye neHaynes242 ngaphandle kokubetha.
