Iimpawu zeMilling Cutters
Ukuzama ukomeleza ukuqina kolu tshintsho phambi kokuba kuqaliswe kuya kuzisa inzuzo kwimveliso yexesha elide kwixesha elizayo. Ayinakwandisa nje ubomi besixhobo, kodwa iphucula umgangatho ongaphezulu we-workpiece kunye nokunciphisa impazamo yomatshini.
Ngokufanayo, ukhetho lomphathi wesixhobo olungafanelekanga luya kunciphisa ubomi besixhobo. Ngokomzekelo, ukuba i-mill end ene-diameter ye-3.175mm ifakwe kwi-cutter holder (endaweni ye-spring chuck), ngenxa yesenzo se-screw yokuqinisa, i-gap edibeneyo phakathi komsiki kunye nomnini we-cutter uthambekele kwelinye. icala, kwaye umbindi womsiki uyaphambuka. Iziko lokujikeleza komphathi wesixhobo kwandisa i-radial runout ye-milling cutter ngexesha lokusebenza, okubangelwa umthwalo ongalinganiyo wokusika kwizinyo ngalinye le-milling cutter. Le meko yokusika ayilunganga isixhobo, ngakumbi xa kugaywa i-nickel-based alloys.
Ngokusebenzisa umnini wesixhobo ophucula ukuchaneka kwesixhobo sokunyuswa kwesixhobo, njenge-hydraulic chuck kunye ne-shrink-fit chuck, isenzo sokusika sinokulinganisela kwaye sizinzile, isixhobo sokugqoka siyancipha, kwaye umgangatho ophezulu uphuculwe. Umgaqo kufuneka ulandelwe xa ukhetha isibambo, oko kukuthi, isibambo kufuneka sibe mfutshane kangangoko kunokwenzeka. Ezi zixhobo zokusebenza kunye neemfuno zokubethelela i-workpiece zisebenza kwi-milling nayiphi na into, kwaye xa ukugaya i-alloys esekelwe kwi-nickel, amava omatshini aphezulu ayafuneka naphi na apho kunokwenzeka.
Ukusetyenziswa kweZixhobo
Kungakhathaliseki ukuba isixhobo senziwe njani, okanye yintoni na into eyenziwa ngayo, umenzi wesixhobo kufuneka anike ixabiso lokuqala lokusika isantya kunye nokutya ngezinyo ngalinye. Ukuba ezi datha azikho, isebe lobugcisa bomenzi kufuneka lidityaniswe. Abavelisi kufuneka bazi ukuba iimveliso zabo zikwazi kangakanani na ukugoba kububanzi obugcweleyo, ukujika, ukugrumba, okanye ukugoqa, kuba uninzi lwabasiki bemihlali bemigangatho bengakwazi ukumelana nale mi sebenzi mininzi. Umzekelo, ukuba i-engile yokusila ayinayo i-engile enkulu ngokwaneleyo yesibini yokucoca, i-engile ye-bevel ye-ramping iyancitshiswa.
Ngokucacileyo, ukuba umthamo womatshini wesixhobo ugqithisiwe, uya kubangela umonakalo kwisixhobo. Kukwanjalo nakwi-plunge milling. Ukuba iitshiphusi azikwazi ukugxothwa ukusuka ezantsi kwi-groove ngexesha, ii-chips ziya kucudiswa kwaye isixhobo siya konakala kamva. Ukuqukumbela, ezi meko ziyingozi kubomi besixhobo xa kusatywa ii-superlloys. Ukuba ubucinga ukuba ukucothisa isantya sesondlo kuya konyusa ubomi besixhobo, kuvele ukuba akulunganga. Umzekelo oqhelekileyo kuxa ukusika kuqala kwenziwa kwaye imathiriyeli ifunyanwe iqinile. Ukuba umxhesho uyancitshiswa (umzekelo, ukutya kwezinyo le-indexable milling cutter kuyancitshiswa ukuya kwi-0.025 ukuya kwi-0.5 mm), umgca wokusika wesixhobo uya kugubha kakhulu i-workpiece, kwaye umphumo uya kuba kukuba isixhobo siya konakala. ngokukhawuleza okanye ngokukhawuleza. I-friction inokubangela ukuqina komsebenzi kumphezulu we-workpiece. Ukuze ugweme ukuqina komsebenzi, umthwalo othile wokusika (0.15-0.2mm / feed ngezinyo) kufuneka ugcinwe xa usika imela yokuqala.
