Lokhu kucaciswa sekuphenduke indinganiso yaseYurophu kanye nendinganiso yamazwe ngamazwe.
Ngokusho kwedatha, izindleko eziqondile zethuluzi zenza kuphela u-2% ~ 4% wezindleko zokukhiqiza, kanti izindleko zokusetshenziswa nokuphathwa kwamathuluzi zingaphezu kuka-12%. Ukuphathwa kwamathuluzi esayensi kungonga umsebenzisi izindleko zamathuluzi futhi kwehlise izindleko zokukhiqiza. Ngakho-ke, ukuthuthukiswa kobuchwepheshe bokuphatha amathuluzi kanye nesofthiwe ehlobene ne-hardware sekuphenduke umkhakha webhizinisi wabakhiqizi bamathuluzi, ohlinzeka abasebenzisi ngezinhlobo ezahlukene zezinsizakalo zokuphatha amathuluzi, kusukela ekuphathweni kwezinto ezilula zamathuluzi kuya ekuhlanganisweni kwenkontileka yawo wonke amabhizinisi amathuluzi, okuhlanganisa ukuthengwa kweThuluzi, ukuhlonza. , isitoreji, isevisi yasendaweni, ukugaywa kabusha kwamathuluzi, ukuthuthukiswa kwenqubo, ukuthuthukiswa kwephrojekthi, njll. Izinkampani zabasebenzisi zingasebenzisa leli thuba lensizakalo yezenhlalakahle ekhethekile, zigcine izinga eliphezulu lokucutshungulwa, futhi zigxile ekuthuthukisweni kobuchwepheshe obuyinhloko, futhi ukuzuza isivuno esiphindwe kabili kwezomnotho nezobuchwepheshe.
Okwesithupha, imodeli yebhizinisi entsha yemboni yamathuluzi.
Ngokuthuthuka kobuchwepheshe bokusika, imboni yamathuluzi yenza izinguquko ezinhlelweni zokusebenza. Njengoba ubhekene nemodeli entsha yokukhiqiza nezinto ezintsha zokusebenza, "amathuluzi" awaseyona imikhiqizo elula. Uma sezithengisiwe, ziyizici zezinqubo ezibalulekile zokuthuthukisa inqubo noma ubuchwepheshe bokucubungula umugqa. Abakhiqizi bamathuluzi kumele bakwazi Ukuhlinzeka abasebenzisi ngobuchwepheshe bokucubungula obuphelele ukuze basize abasebenzisi bafinyelele umgomo wokuthuthukisa ukusebenza kahle kokucubungula, ikhwalithi yomkhiqizo kanye nokunciphisa izindleko zokukhiqiza sekuphenduke isiqondiso nenjongo yebhizinisi yokuthuthukiswa kwebhizinisi labakhiqizi bangaphandle. Njengamanje, abakhiqizi bamathuluzi balethe imboni yamathuluzi esigabeni esiphezulu sokuthuthukiswa ngokusebenzisa izinhlobo ezahlukene zezinsizakalo zebhizinisi ezifana "nokusebenzela abasebenzisi" kanye "nokunikeza izixazululo". Amaqiniso afakazele ukuthi lo mkhuba wabakhiqizi bamathuluzi bakwamanye amazwe uhambisana nokuthuthukiswa kwemboni yokukhiqiza, uletha izinzuzo eziningi kubasebenzisi futhi wamukelwe abasebenzisi.
Sebenzisa ubuchwepheshe bokusika obusezingeni eliphezulu ukusheshisa ukuthuthukiswa kwemboni yokukhiqiza yaseChina
IKhongolose Kazwelonke ye-16 yeQembu LamaKhomanisi laseShayina yabeka phambili umsebenzi wokwakha umphakathi omi kahle ngendlela yawo wonke kanye nokuqaphela ukuthuthuka kwezimboni okusha. Yashaya uphondo lwemashi yaseShayina isuka emandleni okukhiqiza yaya emandleni okukhiqiza. Njengobuchwepheshe obuyisisekelo bokukhiqiza ubuchwepheshe, ithuluzi lokusika liyimishini yenqubo eyisisekelo. Isendaweni yokuqala kule mashi eyingqophamlando. Ubuchwepheshe bokusika obuthuthukisiwe kanye namathuluzi okusika ukuthuthukiswa kweShayina kwemboni yezimoto, imboni ye-aerospace, imboni yamandla kanye nemishini esekelayo. Okudingekayo embonini yesikhunta. Lapho sibhekene naleli thuba elikhulu kangaka, kufanele sisebenzise ngokugcwele ubuchwepheshe bokusika obuthuthukile kanye namathuluzi okusika ukuze sikhonze imboni yokukhiqiza yaseChina.
Kuze kube manje, imboni yamathuluzi yaseShayina isheshisa ukuhlanganiswa kwayo nemboni yamathuluzi yomhlaba wonke, yethula imishini yenqubo ethuthukisiwe nobuchwepheshe ngoguquko lwezobuchwepheshe, nokuthuthukisa nokukhiqiza imikhiqizo yamathuluzi esezingeni lokuqala. Imboni yamathuluzi yaseChinaabahamba phambili ababili - I-Zhuzhou Cemented Carbide Group kanye ne-Shanghai Tool Factory Co., Ltd. bahole ekwenzeni uguquko lwezobuchwepheshe olunesiqalo esiphakeme kanye nokutshalwa kwezimali okukhulu, okwenze ubuchwepheshe bokukhiqiza izinto ezifakwayo ezifakwayo neziqinile ze-carbide e-China bavala. Izinga eliphezulu emhlabeni. Ngesikhathi esifanayo, izinkampani zangaphandle zamathuluzi zibhekene nentuthuko esheshayo yemboni yokukhiqiza yaseShayina kanye nethuba lokuthuthuka ngokushesha, ukusheshisa ijubane lokukhiqiza noma isevisi yendawo eShayina, ukuze kuncishiswe izindleko zokukhiqiza, ukuthuthukisa amakhono esevisi, kanye nokunciphisa umthofu. izikhathi. Kuthiwa ukungena kwezinkampani zamathuluzi angaphandle emakethe yaseShayina kunikeza izimo ezikahle kakhulu zokuthi sisebenzise amathuluzi athuthukile ukuze siguqule ukukhiqizwa kwendabuko. Kufanele sibambe leli thuba elihle futhi sisebenzise amathuluzi okusika athuthukile ukuze sihlangabezane nezinselele zokuhwebelana kwezomnotho ukuze sithuthukise ubuchwepheshe bokucubungula namandla okuncintisana ezinkampani.
Lapho amabhizinisi esheshisa ukusetshenziswa kobuchwepheshe bokusika obuphambili, isimo sebhizinisi ngalinye sihlukile, futhi izinqubo ezithile zihlukile, kepha amaphuzu alandelayo angasetshenziswa njengombono ojwayelekile:
Amathuluzi enziwe ngezinto zamathuluzi ezisebenza kahle kakhulu, okuhlanganisa amathuluzi aqinile e-carbide, amathuluzi e-silicon nitride ceramic, amathuluzi e-CBN nawe-PCD, amathuluzi ensimbi asebenza ngesivinini esiphezulu, njll., uhlobo olulodwa lwesingeniso sesimo esithile sokukhiqiza, isinyathelo ngesinyathelo. Push, uzothola imiphumela emihle; okwamanje abakhiqizi bamathuluzi asekhaya nabo banganikezela ngale mikhiqizo yamathuluzi.
Sebenzisa kakhulu amathuluzi ahlanganisiwe. Ingxenye yemimese eboshwe e-China iphansi kakhulu, futhi kunesikhala esikhulu sokuphromotha. Ibanga elifanele lokugqoka kufanele likhethwe ngokuvumelana nezimo zokucubungula futhi lidinga ukufeza imiphumela oyifunayo.
Ukusetshenziswa kwamathuluzi ezinkomba kusetshenziswa kakhulu. Amathuluzi anenkomba aye akhuthazwa e-China iminyaka eminingi, kodwa inqubekelaphambili ayizange isheshe ngokwanele ngenxa yezizathu ezihlukahlukene.
Intuthuko ayilingani. Kodwa-ke, phakathi nalesi sikhathi, ubuchwepheshe bamathuluzi e-indexable buye benza inqubekelaphambili entsha, izinhlobonhlobo zanda ngokushesha, futhi ziye zathuthuka ngendlela ephumelelayo futhi esebenzayo. Kwakhiwe izindwani zokusika zokugaya ezigobile, izinsimbi eziphendukayo ezinama-wiper blades kanye nenjongo evamile. Imikhiqizo enama-blade ayindilinga amahle nama-octagonal blades inamandla amakhulu okusetshenziswa. Ukukhuthaza amathuluzi anezinkomba ngokukhuthele kufanele kube iphrojekthi ebalulekile yokuguqulwa kwezobuchwepheshe kwamabhizinisi. Umfanekiso wesi-7 wumshini wokusika ogobile ofakwe onqenqemeni owenziwe ngabakwaHunan Diamond Cutting Tool Co., Ltd.
Olayini abakhulu bokukhiqiza, kufanele sifunde kokuhlangenwe nakho kwamanye amazwe, sithuthukise izinqubo ezintsha namathuluzi akhethekile, sithuthukise ukusebenza kahle futhi sinciphise izindleko, noma sithuthukise izinqubo zokugxilisa amathuluzi ahlanganisiwe ukuze kuthuthukiswe ukusebenza kahle nokunciphisa ukutshalwa kwezimali. Umsebenzi onjalo kufanele uhlanganiswe nabakhi bamathuluzi omshini kanye nabakhiqizi bamathuluzi ukuze kuzuzwe imiphumela. Lona umkhuba ovuthiwe emazweni anezimboni.
Ezinkampanini ezinemodi yokukhiqiza yenqwaba encane yesiqephu esisodwa, amathuluzi amasha asebenzayo afana nezinsimbi zokupholisa zangaphakathi kanye nezigayo zokuphela kobuso be-rake kufanele zisetshenziswe. Okwesibili, ama-multi-function cutter universal angasetshenziswa, anganciphisa isikhathi sokushintsha kwamathuluzi. Kuyadingeka futhi ukwephula imikhawulo yenqubo yendabuko yokumba, ukugaya, ukugaya, njll., kanye nokufeza imiphumela emisha yokucubungula ngenqubo yokugaya, ukugaya, ukugaya, ukugaya, ukugaya, nokugaya. Ngaphezu kwalokho, qinisa ukuphathwa kwamathuluzi, wehlise i-inventory futhi unciphise izindleko zamathuluzi.
Lapho besebenzisa amathuluzi okusika athuthukile nobuchwepheshe obusha, amabhizinisi kufanele athembele emandleni obuchwepheshe abakhiqizi nabasabalalisi bamathuluzi ukuze balandele indlela yokuxhumana nabantu. Esimeni samanje sezinto ezintsha zokusebenza, izinto zamathuluzi kanye namamaki okuhlanganisa, kunezinkulungwanekwezinhlobo zamathuluzi. Ngosizo lwabachwepheshe babo kuphela ongakhetha ithuluzi elifanele futhi ufinyelele umgomo oyifunayo. Lona futhi ukukhiqizwa kwamathuluzi angaphandle kwamanje. Ifilosofi yebhizinisi "yokunikezwa kwesistimu" kanye "nokunikeza izixazululo" ekhuthazwa kakhulu yinkampani. Okwesibili, kuyadingeka ukwephula umqondo ongalungile wezindleko zethuluzi--ucabanga ukuthi ithuluzi elihle libiza kakhulu ukulisebenzisa. Yilo mbono osekuyisikhathi eside uthinta inqubekelaphambili yobuchwepheshe bokusika eShayina kanye nokuthuthukiswa kwemboni yamathuluzi kazwelonke. Ithuluzi "liyabiza" futhi libiza kuphela u-2% ~ 4% wezindleko zokukhiqiza (ngaphansi kuka-2% kumabhizinisi amaningi e-China). Kuphela ngokusebenzisa ummese "obizayo", ukusebenza kahle kungancishiswa kakhulu ukunciphisa kakhulu izindleko zesiqephu esisodwa. Izinzuzo zebhizinisi ekugcineni zizofinyelela umphumela wokutshalwa kwezimali okuncane kanye nomphumela omningi. Ngezibonelo ezithile zokucubungula, kungafakazelwa ukuthi izindleko zethuluzi azikho ngaphezu komkhiqizo ngamunye.
Okokugcina, ngithemba ukuthi ngemizamo yawo wonke umuntu, ubuchwepheshe bokusika balolu phiko buzohlanganiswa ukuze bufake isandla ekuthuthukisweni kobuchwepheshe bokukhiqiza nokukhiqiza baseShayina.
