Izici zeMilling Cutters
Ukuzama ukuqinisa ukuqina kwesakhiwo ngaphambi kokuthi kuqale ukucutshungulwa kuzoletha izinzuzo ekukhiqizeni isikhathi eside esikhathini esizayo. Akugcini nje ukwandisa impilo yethuluzi, kodwa futhi kuthuthukisa izinga eliphezulu le-workpiece futhi kunciphisa iphutha lomshini.
Ngokufanayo, ukukhetha okungalungile komphathi wamathuluzi kuzofinyeza impilo yamathuluzi. Isibonelo, uma isigayo sokugcina esinobubanzi obungu-3.175mm sifakwe kusibambi sokusika (esikhundleni se-spring chuck), ngenxa yesenzo sesikulufu esiqinisayo, igebe elifanelekile phakathi komsiki kanye nesibambi sokusika lichemekile kokukodwa. ohlangothini, futhi isikhungo somsiki sichezukile. Isikhungo sokuzungezisa somphathi wamathuluzi sinyusa ukuphuma kwe-radial kwesisiki sokugaya ngesikhathi sokusebenza, okuholela kumthwalo wokusika ongalinganiseli kuzinyo ngalinye lesisiki sokugaya. Lesi simo sokusika asilungile ethuluzini, ikakhulukazi uma kugaywa ama-alloys asekelwe ku-nickel.
Ngokusebenzisa isibambi samathuluzi esithuthukisa ukunemba kokukhwezwa kwamathuluzi, okufana ne-hydraulic chuck kanye ne-shrink-fit chuck, isenzo sokusika singabhalansisisa futhi sizinze, ukuguga kwethuluzi kuyehliswa, futhi nekhwalithi yangaphezulu iyathuthukiswa. Kufanele kulandelwe isimiso lapho kukhethwa isibambo, okungukuthi, isibambo kufanele sibe mfushane ngangokunokwenzeka. Lezi zidingo zokuhlanganisa amathuluzi nezingcezu zokusebenza zisebenza ekugayeni noma iyiphi into, futhi lapho kugaya ama-alloys asekelwe ku-nickel, isipiliyoni somshini esithuthukisiwe siyadingeka lapho kunokwenzeka khona.
Ukusetshenziswa Kwamathuluzi
Kungakhathaliseki ukuthi ithuluzi liklanywe kanjani, noma ukuthi lenziwe ngaziphi izinto, umenzi wamathuluzi kufanele anikeze amanani okuqala okusika isivinini kanye nokudla kwezinyo ngalinye. Uma le datha ingatholakali, umnyango wezobuchwepheshe womkhiqizi kufanele uthintwe. Abakhiqizi kufanele bazi ukuthi imikhiqizo yabo ikwazi kangakanani ukugoqa ngobubanzi obugcwele, ukukhonta, ukuphonseka, noma ukugoqa, njengoba iningi labasiki begayo abajwayelekile abakwazi ukuphatha le misebenzi eminingi. Isibonelo, uma isisiki sokugaya singenayo i-engeli enkulu ngokwanele yesibili yokususa, i-engeli ye-bevel ye-ramping iyancishiswa.
Ngokusobala, uma umthamo womshini wethuluzi weqiwe, uzodala umonakalo ethuluzini. Kungokufanayo nakuma-plunge milling. Uma ama-chips engakwazi ukuxoshwa kusukela phansi kwe-groove ngesikhathi, ama-chips azocindezelwa futhi ithuluzi lizolimala kamuva. Sengiphetha, lezi zimo ziyingozi empilweni yamathuluzi lapho kugaywa ama-superalloy. Uma ubucabanga ukuthi ukwehlisa izinga lokuphakelayo kuzonyusa impilo yamathuluzi, kuvele ukuthi akulungile. Isibonelo esijwayelekile yilapho ukusika kuqala kwenziwa futhi impahla itholakala iqinile. Uma okuphakelayo kuncishisiwe (isibonelo, okuphakelayo kwezinyo ngalinye le-indexable cutter cutter yehliswa ibe ngu-0.025 kuya ku-0.5 mm), umkhawulo wokusika wethuluzi uzowuhlikihla kakhulu ucezu lokusebenza, futhi umphumela uzoba ukuthi ithuluzi lizolimala. ngokushesha noma ngokushesha. I-Friction ingabangela ukuqina komsebenzi phezu kwendawo yokusebenza. Ukuze ugweme ukuqina komsebenzi, umthwalo othile wokusika (0.15-0.2mm/feed ngezinyo ngalinye) kufanele ugcinwe lapho usika ummese wokuqala.
