Kwinkqubo yokugaya, indlela yokukhetha efanelekileyoI-CARBIDE END MILLkwaye ugwebe ukunxiba komsiki wokusila ngexesha alinako nje ukuphucula ngokufanelekileyo ukusebenza kakuhle, kodwa nokunciphisa iindleko zokusetyenzwa.
IiMfuno eziSisiseko zeMathiriyeli ye-End Mill:
1. Ubunzima obuphezulu kunye nokuxhatshazwa kokugqoka
Kwiqondo lokushisa eliqhelekileyo, inxalenye yokusika yezinto kufuneka ibe nobunzima obaneleyo bokusika kwi-workpiece;ngokuchasa okuphezulu, isixhobo asiyi kunxiba kwaye sandise ubomi benkonzo.
2. Ukumelana nobushushu obuhle
Isixhobo siya kuvelisa ubushushu obuninzi ngexesha lokusika, ngakumbi xa isantya sokusika siphezulu, iqondo lokushisa liya kuba liphezulu kakhulu.
Ngoko ke, izixhobo zesixhobo kufuneka zibe nokumelana nokushisa okulungileyo, okunokugcina ubunzima obuphezulu nakwiqondo lokushisa eliphezulu, kwaye inokumelana nokushisa okulungileyo.Ukukwazi ukuqhubeka nokusika, le propati enobunzima obuphezulu beqondo lokushisa, eyaziwa ngokuba yi-hot hardness okanye i-red hardness.
3. Amandla aphezulu kunye nokuqina okulungileyo
Kwinkqubo yokusika, isixhobo kufuneka sithwale impembelelo enkulu, ngoko ke isixhobo kufuneka sibe namandla aphezulu, ngaphandle koko kulula ukuphuka kunye nokulimala.Ukususela kwiumsiki wokugayaixhomekeke kwimpembelelo kunye nokungcangcazela, izinto ze-milling cutter kufuneka zibe nobunzima obuhle, ukwenzela ukuba kungabikho lula ukukrazula kunye nokuphuka.
Iimbangela zokunxiba komsiki wokuguba
Izizathu zokunxitywa kweisiphelo sokusilazintsonkothe ngakumbi, kodwa zinokwahlulwa ngokurhabaxa okanye ikakhulu zibe ngamacandelo amabini:
1. Ukunxiba oomatshini
Ukunxitywa okubangelwa kukungqubana okukhulu phakathi kwetshiphu kunye neraki yobuso besixhobo, i-elastic deformation yomphezulu womatshini womsebenzi kunye neflank yesixhobo ibizwa ngokuba yi-mechanical wear.Xa ubushushu bokusika bungekho phezulu kakhulu, i-abrasion mechanical ebangelwa yile friction iyona nto ibangela ukugqoka izixhobo.
2. Ukunxiba kwe-thermal
Ngexesha lokusika, ngenxa ye-deformation yeplastiki enzima yentsimbi kunye nokushisa okusika okwenziwa yi-friction, ukugqoka okubangelwa ukunciphisa ubunzima be-blade kunye nokulahlekelwa kwentsebenzo yokusika kubizwa ngokuba yi-thermal wear.
Ukongeza kwezi ntlobo zimbini zokunxiba, kukho ezi ndidi zilandelayo zokunxiba:
Ngaphantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu, kuya kubakho into edibeneyo phakathi kwesixhobo kunye nesixhobo sokusebenza, kwaye inxalenye yesixhobo iya kuthathwa yi-chips, ebangela ukuba isixhobo siboshwe kwaye sigqoke.
Kwiqondo lokushisa eliphezulu, ezinye izinto kwisixhobo sesixhobo (ezifana ne-tungsten, i-cobalt, i-titanium, njl.njl.) ziya kusasazeka kwizinto zokusebenza, ngaloo ndlela zitshintsha ukubunjwa kweekhemikhali zomgangatho ophezulu wecandelo lokusika isixhobo, kunye nokunciphisa amandla. kunye nokunxiba ukuchasana kwesixhobo, ukuze isixhobo sivelise ukunxiba kwe-diffusion.
Kwizixhobo zetsimbi ezikhawulezayo, kwiqondo lokushisa eliphezulu lokusika, isakhiwo se-metallographic sobuso besixhobo siya kutshintsha, ukunciphisa ubunzima kunye nokuxhatshazwa kokugqoka, kunye nokuguqulwa kwesigaba kuya kwenzeka.Izinyo ngalinye le-milling cutter yi-periodic intermittent cut.Ubushushu bezinyo buhluka kakhulu ukusuka kwi-stroke engasebenziyo ukuya ekusikeni.Kunokuthiwa ixesha ngalinye lingena kwi-cut, liphantsi kokutshatyalaliswa kwe-thermal.Izixhobo zeCarbide, phantsi kokutshatyalaliswa kwe-thermal, ziya kuvelisa uxinzelelo oluninzi ngaphakathi kwe-blade, kwaye kubangele ukuqhekeka, okubangelwa ukuchithwa kwe-thermal kunye nokugqoka isixhobo.Ekubeni i-cutter yokugaya inqumla ngokuphindaphindiweyo, iqondo lobushushu lokusika alikho phezulu njengalo ekujikeni, kwaye unobangela oyintloko wokunxitywa kwesixhobo ngokuqhelekileyo unxitywa ngoomatshini obangelwa kukungqubana komatshini.
Ukuqonda njani ukunxitywa kwesixhobo?
1. Okokuqala, gweba ukuba igugile okanye ayikho ngexesha lokucubungula.Ngokukodwa kwinkqubo yokusika, mamela isandi.Ngokukhawuleza, isandi sesixhobo ngexesha lokucubungula asikho ukusika okuqhelekileyo.Kakade ke, oku kufuna ukuqokelela amava.
2. Jonga inkqubo.Ukuba kukho iintlantsi eziphazamisayo eziphazamisayo ngexesha lokucutshungulwa, oko kuthetha ukuba isixhobo sigugile, kwaye isixhobo sinokutshintshwa ngexesha ngokwe-avareji yobomi besixhobo.
3. Jonga umbala weefayili zentsimbi.Umbala weefayili zetsimbi uyatshintsha, obonisa ukuba izinga lokushisa lokucubungula litshintshile, elinokuthi libe sisixhobo sokugqoka.
4. Ukujonga imilo yeefayili zentsimbi, kukho iimilo ezinqamlekileyo kumacala omabini eefayili zetsimbi, iifayili zentsimbi zigobile ngokungaqhelekanga, kwaye iifayili zentsimbi ziba ngcono, ngokucacileyo akuyiyo imvakalelo yokusika eqhelekileyo, ebonisa ukuba. isixhobo sinxitywe.
5. Ukujonga umphezulu womsebenzi, kukho iimpawu eziqaqambileyo, kodwa uburhalarhume kunye nobukhulu abuzange butshintshe kakhulu, eyona nto isetyenziswe isixhobo.
6. Ukuphulaphula isandi, i-vibration yomatshini iyancipha, kwaye isixhobo siya kuvelisa ingxolo engaqhelekanga xa isixhobo singakhawulezi.Ngeli xesha, kufuneka sinikele ingqalelo ukuphepha "ukunamathela kwemela", okuya kubangela ukuba i-workpiece ikhutshwe.
7. Qwalasela umthwalo wesixhobo somatshini.Ukuba kukho utshintsho oluphawulekayo olongezelelweyo, isixhobo sinokunxitywa.
8. Xa isixhobo sinqunyulwa, i-workpiece inee-burrs ezinzulu, uburhabaxa buncitshisiwe, ubungakanani bokutshintsha kwe-workpiece kunye nezinye izinto ezicacileyo nazo ziyimilinganiselo yokumisela ukunxiba kwesixhobo.
Ngamafutshane, ukubona, ukuva, kunye nokuchukumisa, ukuba nje unokushwankathela inqaku elinye, unokugweba ukuba isixhobo sinxibile okanye hayi.
