Okokugaga
Njengamanje, imishini yezindiza ezinkulu zama-cylinder block namakhanda amasilinda ezinjini ngokuvamile isebenzisa ubuchwepheshe bokugaya. Thatha ukugaya kwesilinda se-Iron Scying Centre esikhungweni esisheshayo mashini yokugaya ngesibonelo, usebenzisa i-cubic boron nitride (CBN) ukufakwa, futhi isivinini saso sokusika singafinyelela ku-700-1500m / min.
Ukusebenza kahle kokukhiqizwa kokugaya kwenziwa ngcono kakhulu. Okwezinhloko zama-aluminium alloy ama-cylinder, abasiki bemishini yobuso basetshenziselwa ukusika okusheshayo. Usebenzisa ukufakwa kwe-PCD, ububanzi be-milling cutter buhliswa kancane kancane, kanye nokuthuthukiswa kokusebenza okugcwele okukuhle.
Okokumbaya
Enqubweni yokukhiqiza injini, ingxenye ye-Hole Procution nayo iphakeme kakhulu, ikakhulukazi inani lokucutshungulwa kwembobo amakhanda amasilinda namabhulokhi amasilinda. Phakathi kwazo, ukucubungula ukucubungula ama-akhawunti acishe abe ngu-60%, alandelwa ukucubungula okujabulisayo nokushaya ukucubungula. Ukusetshenziswa kwamathuluzi wokusika wejubane eliphezulu
Umlando wokuthuthukiswa kwemishini ephezulu yemishini umlando wokuthuthuka okuqhubekayo kwezinto zokwakha amathuluzi. Amathuluzi amaningi asetshenziswa yiShenzhen Ruiyang Technology Co, Ltd ekusebenziseni kokuqala kwamathuluzi angeniswa, futhi aqhutshwa enziwe ngokwenziwa kwasendaweni. Manje amathuluzi asetshenziswa kakhulu afaka amathuluzi we-CBN ne-PCD, amathuluzi we-carbide ahlanganisiwe, amathuluzi obuse-ceramic, njll.. Ngaphezu kwalokho, ukuphumelela okukhulu kwenziwe ekwenzeni kwasendaweni kwamathuluzi okubukelayo.
1. Amathuluzi we-CBN ne-PCD
Izinto ezimele zamathuluzi zokusika ngejubane eliphezulu yi-CBN ne-PCD. Lapho usebenzisa amathuluzi we-CBN ukuze acale ubuso, isivinini sokusika singafinyelela ku-5000m / min. Imishini emgodini wangaphakathi we-20CRMO5 Gearl Gear (60hrc) ngethuluzi le-CBN, ubulukhuni bendawo bungafinyelela ku-0.22μm, obuye baba ubuchwepheshe obusha obuthuthukiswe ngumkhakha wezimoto ekhaya nakwamanye amazwe. I-Camshafts kanye ne-crankshafts futhi basebenzisa amasondo okugaya kwe-CBN ngokugaya okusheshayo; Amathuluzi we-PCD asetshenziswa kabanzi ekugayeni kwamabhulokhi amasilinda kanye ne-cylinder ikhanda aluminium alloy izinto zokwakha. Ukubheka ukuthi ukujikeleza okusheshayo okuphezulu kuzokhiqiza amandla amakhulu e-centrifugal, umzimba wamathuluzi usebenzisa amandla aphezulu okwenziwe nge-aluminium alloy impahla.
Isondo lokugaya le-alumina. Ngoba i-alumina base inokuqina okuphezulu kwamakhemikhali kanye nezimpawu ezithandekayo ezishisayo, kucatshangelwa ukusebenza kanye nomnotho, kusetshenziswe ikakhulukazi kwi-main maturey cylindrical grinder enamasondo amakhulu okugaya, bheka umfanekiso 7) Kusetshenziswe ku-crankshaft kuxhuma ama-grinders entamo entanjeni yentamo nge-cylindrical ngezidingo zokulandela eziphakeme.
2. Ithuluzi le-Carbide
Ukusika okuyingxenye kanzima kuyinkambu yesicelo ebalulekile yobuchwepheshe bokusika ngejubane eliphezulu. Okungukuthi, amathuluzi angashadile noma ama-multi-odge asetshenziselwa ukucubungula izingxenye ezilukhuni. Isebenza kangcono ukwedlula ukugaya kwendabuko, futhi yenza lula izindlela zenqubo nezixhumanisi, ezingagcini nje kuphela izindleko, kodwa futhi nezimo ngokwengeziwe.
Ekuhlobiseni nasemaketheni yokugaya, i-carbide eyi-ultra-fined ehlelwe ngocingo ilungele izinhlelo eziningi. Futhi banobunzima obuphakeme nokumelana okuhle kakhulu kokushisa, okungahlanganisa ama-geometrise amahle wokusika ngama-race ama-bacle amakhulu. Futhi i-angle yemvume ihlanganisiwe, ukuboniswa okuqondile kwalezi zici ukunciphisa amandla okusika nokushisa okushisa; Lapho uthinta, ikakhulukazi amazinga okushisa aphezulu aphezulu ngesivinini esiphezulu esisheshayo adinga izinto ezinzima zokuqina ukushisa.
3. Ubuchwepheshe be-Tool coating
Ukuze wenze amathuluzi okusika ngentengo ephansi kanye nokusebenza okuhle kakhulu, okunganciphisa ngempumelelo izindleko zokucubungula, ubuchwepheshe be-coating okwamanje okuyisinqumo sokuqala.
Umsebenzi we-coating yamathuluzi: Kungathuthukisa ukumelana nokugqoka, ukukhulisa impilo yamathuluzi, futhi uthuthukise ukusebenza kokusika; Ukuba khona kwe-coating kunciphisa ukungqubuzana phakathi kwethuluzi ne-chip, ngaleyo ndlela kwandise ukujula kokumba.
Yehlisa amandla okusika; Ukubukeka okukhanyayo okukhanyayo (ophuzi wegolide, obomvu womlilo, njll.), Kulula ukubheka ukugqokwa kwethu; ukuba khona kwe-coating komhlaba kunganciphisa ukusika ukushisa nokunciphisa ukusebenzisana kokushisa phakathi kwethuluzi kanye ne-workpiece (ukwahlukaniswa kokwehlukaniswa) ithuluzi kanye nomsebenzi wokusebenza, vimba ukusabela kwamakhemikhali; Umehluko we-thermal wokuphamba phakathi kokuhlanganiswa nethuluzi kunganciphisa ukunqwabelana kokushisa ethubeni); I-coating esezingeni eliphakeme ingathuthukisa ukusebenza kwethuluzi futhi inciphise ukwakheka kwemiphetho eyakhelwe phansi kanye nama-craters akhona.
Ukuhlaziywa okuphelele komnotho nokusebenza kwama-coati, ama-End Mills asetshenziswa nguShenzhen Ruiyang Technology Co, Ltd for Speed High Speed are aphathwe ubuchwepheshe be-tialn composite obuhlukahlukene, kanye nempilo yokudla okuhlukile ukumboza.
