I-Komatsu yinkampani ekhiqiza amakhemikhali esindayo ezinze eJapan. Le nkampani ikleliswe kuqala phakathi kwabakhiqizi bemishini yamakhemikhali esindayo eJapan futhi ingeyesibili emhlabeni. Imikhiqizo eyinhloko kaKomatsu ihlanganisa ama-cranes, ama-bulldozer kanye nama-excavators
Isethulo senqubo eyinhloko
(1) Intamo yokuphotha ye-Crankshaft kanye nentamo yenduku yokuxhuma ukugaya kwangaphandle
Ekucutshungulweni kwezingxenye ze-crankshaft, ngenxa yethonya lesakhiwo se-disc milling cutter ngokwayo, i-blade ne-workpiece zihlala zithintana ngezikhathi ezithile futhi zinomthelela. Ngakho-ke, isixhumanisi segebe silawulwa kulo lonke uhlelo lokusika lwethuluzi lomshini, okunciphisa ukudlidliza okubangelwa igebe lokunyakaza ngesikhathi senqubo yomshini, ngaleyo ndlela kuthuthukiswe ukunemba kwemishini kanye nempilo yesevisi yethuluzi.

(2) Intamo yokuphotha i-crankshaft kanye nokugaya intamo yenduku
Indlela yokugaya yokulandelela ithatha umugqa omaphakathi wentamo ye-shaft enkulu njengesikhungo sokujikeleza, futhi iqedela ukugaya intamo yenduku ye-crankshaft ngokushintshana ngokucindezela okukodwa (ingasetshenziswa futhi ekugayeni intamo ye-shaft enkulu). Ijenali ye-shaft ye-grinding rod yenziwa ngokulawulwa kwe-CNC kokuphakelayo kwesondo lokugaya kanye nokuzungezisa isiqeshana sokusebenza ukuze kuqedelwe okuphakelayo komshini we-crankshaft. Indlela yokugaya yokulandelela isebenzisa i-clamping eyodwa, ukugaya i-crankshaft spindle kanye nokuxhuma intamo yenduku ngokulandelana emshinini wokugaya we-CNC, onganciphisa ngempumelelo izindleko zemishini, unciphise izindleko zokucubungula, futhi uthuthukise ukunemba kokucubungula nokusebenza kahle kokukhiqiza.

(3) intamo yokuphotha i-crankshaft, umshini wokugoqa ekhoneni eliyindilinga oxhumayo
Umshini wokugoqa usetshenziselwa ukuthuthukisa amandla okukhathala kwe-crankshaft. Ngokwezibalo, impilo ye-crankshaft ye-nodular cast iron crankshaft inganyuswa ngo-120% ~ 230% ngemva kokugoqa okuyindilinga; Impilo ye-crankshaft yensimbi eyenziwe ngomgunyathi ingakhuphuka ngo-70% ~ 130% ngemuva kokugingqika okuyindilinga. Amandla ajikelezayo okugoqa avela ekujikelezeni kwe-crankshaft, okushayela i-roller ekhanda eligoqayo ukuze ijikeleze, futhi ukucindezela kwe-roller kwenziwa yisilinda.
