Emishinini yokulawula izinombolo ye-CNC, nakuba igwadule isiphenduke into ebalulekile ngenxa yezakhiwo zayo ezihlukile, izithiyo zayo ezingokwemvelo zingase zibe nomthelela othile ekusebenzeni kwemishini, ukusebenza kahle kokucubungula kanye nezindleko zokuwulungisa. Okulandelayo ukuhlaziya imithelela ethile elethwa ukushiyeka kwegwadle kusuka kubukhulu obuningi:
Okokuqala, i-material i-brittle kakhulu futhi ijwayele ukuphuka nokulimala
I-drawback eyinhloko: I-Granite iyitshe lemvelo futhi empeleni iyimpahla ephukayo enokuqina okungekuhle komthelela (inani lokuqina komthelela licishe libe ngu-1-3J/cm², eliphansi kakhulu kuno-20-100J/cm² wezinto zensimbi).
Umthelela kumishini ye-CNC:
Izingozi zokufaka nezokuthutha: Ngesikhathi sokuhlanganiswa noma ukuphathwa kwezinto zokusebenza, uma zishayisana noma zehla, izingxenye zegwadle (njengezisekelo namalayili okuqondisa) zijwayele ukuqhekeka noma amakhona aqhephukile, okuholela ekuhlulekeni kokunemba. Isibonelo, uma iplatifomu yegwadle yomshini wokulinganisa wezixhumanisi ezintathu iqala ukuqhekeka okufihliwe ngenxa yokusebenza okungafanele ngesikhathi sokufakwa, kungase kuholele ekuwohlokeni kancane kancane kokucaba ngokusetshenziswa kwesikhathi eside, kuthinte imiphumela yokulinganisa.
Izingozi ezifihliwe enqubweni yokucubungula: Uma okokusebenza kwe-CNC kuhlangabezana nokugcwala okuzumayo (okufana nethuluzi elishayisana nengxenye yokusebenza), amarayili omhlahlandlela wegwadle noma amatafula okusebenza angase aphuke ngenxa yokungakwazi ukumelana namandla omthelela osheshayo, okubangela ukuthi okokusebenza kuvaleke ukuze kulungiswe, futhi kubangele ngisho nokwehluleka ukunemba kwechungechunge.
Okwesibili, ubunzima bokucubungula okuphezulu bukhawulela ukuklama kwezakhiwo eziyinkimbinkimbi
Izithiyo eziwumgogodla: I-Granite inobunzima obuphezulu (6-7 esikalini se-Mohs), futhi idinga ukugaywa futhi icutshungulwe ngamathuluzi akhethekile njengamasondo okugaya idayimane, okuholela ekusebenzeni kahle kokucubungula (ukusebenza kahle kokugaya kungu-1/5 kuya ku-1/3 kuphela wezinto zensimbi), futhi izindleko zokucubungula izindawo eziyinkimbinkimbi ezigobile ziphezulu.
Umthelela kumishini ye-CNC:
Imikhawulo yokuklama kwesakhiwo: Ukuze ugweme ubunzima bokucubungula, izingxenye ze-granite zivame ukuklanywa ngendlela elula yejiyomethri (njengamapuleti, ama-rectangular guide rails), okwenza kube nzima ukufeza imigodi yangaphakathi eyinkimbinkimbi, amapuleti aqinile angasindi kanye nezinye izakhiwo ezingafezwa ngokuphonsa / ukusika ngezinto zensimbi. Lokhu kuholela eqinisweni lokuthi isisindo sesisekelo se-granite sivame ukuba sikhulu kakhulu (i-10% -20% inzima kune-cast iron yevolumu efanayo), okungase kwandise umthwalo ophelele wemishini futhi kuthinte ukusebenza kokuphendula okuguquguqukayo ngesikhathi sokunyakaza kwesivinini esikhulu.
Izindleko eziphezulu zokulungisa nokushintsha: Uma ukuguga kwendawo noma ukulimala kwenzeka ezingxenyeni zegwadle, kuba nzima ukuzilungisa ngokusebenzisa izindlela ezifana nokushisela noma ukusika. Ngokuvamile, yonke ingxenye idinga ukushintshwa, futhi izingxenye ezintsha zidinga ukugaywa kabusha futhi zilinganiswe ngokunemba, okuholela ekunciphiseni isikhathi eside (ukushintsha okukodwa kungathatha amaviki angu-2-3), kanye nokwenyuka okukhulu kwezindleko zokunakekela.
Iii. Ukungaqiniseki Kokwakheka Kwemvelo kanye Nokukhubazeka Kwangaphakathi
I-drawback eyinhloko: Njengemaminerali yemvelo, i-granite inemifantu yangaphakathi engalawuleki, ama-pores noma ukungcola kwamaminerali, futhi ukufana kwezinto ezibonakalayo kwemithambo ehlukene kuyahluka kakhulu (ukushintshashintsha komthamo kungafinyelela ku-±5%, ukuguquguquka kwe-elastic modulus ± 8%).
Umthelela kumishini ye-CNC:
Ingozi yokuzinza ngokunemba: Uma indawo yokucubungula yengxenye kwenzeka ukuthi iqukethe ukuqhekeka kwangaphakathi, ngesikhathi sokusetshenziswa isikhathi eside, ukuqhekeka kungase kunwebe ngenxa yokucindezeleka, okubangela ukuguqulwa kwendawo futhi kuthinte ukunemba kwemishini. Isibonelo, uma ama-rail omhlahlandlela we-granite womshini wokugaya we-CNC enezimbobo zomoya ezifihlekile, angase awe kancane kancane ngaphansi kokudlidliza kwe-high-frequency, okuholela ephutheni eliqondile lokuqondisa kwamareyili angumhlahlandlela.
Umehluko wokusebenza kweqoqo: Izinto ze-granite ezivela kumaqoqwana ahlukene zingase zibe nokuguquguquka kwezinkomba ezibalulekile ezifana ne-coefficient yokwanda okushisayo nokusebenza kokudambisa ngenxa yomehluko ekubunjweni kwamaminerali, okuthinta ukuvumelana kokukhiqizwa kwenqwaba ngamathuluzi. Ngemigqa yokukhiqiza ezenzakalelayo edinga ukusebenzisana kwamadivayisi amaningi, umehluko onjalo ungaholela ekwenyukeni kokusatshalaliswa kokunemba kokucubungula.
Okwesine, kuyasinda, okuthinta ukusebenza okuguquguqukayo kwemishini
I-Core drawback: I-Granite inokuminyana okuphezulu (2.6-3.0g/cm³), futhi isisindo sayo cishe siphindwe izikhathi ezingu-1.2 kunesansimbi ewuketshezi kanye nezikhathi ezingu-2.5 kune-alloy ye-aluminium ngaphansi kwevolumu efanayo.
Umthelela kumishini ye-CNC:
I-Motion response Lag: Ezikhungweni zemishini yesivinini esikhulu noma emishinini ye-axis emihlanu, isisindo esikhulu sesisekelo se-granite sizokwandisa inertia yomthwalo we-linear motor / isikulufu somthofu, okuholela ekubambezelekeni kokuphendula okuguquguqukayo ngesikhathi sokusheshisa/ukunciphisa (okungase kwandise isikhathi sokuqala-sokumisa ngo-5% kuya ku-10%), okuthinta ukusebenza kahle kokucubungula.
Ukwenyuka kokusetshenziswa kwamandla: Ukushayela izingxenye zegwadle esindayo kudinga ama-servo motors anamandla, aphakamisa ukusetshenziswa kwamandla okuphelele kwemishini (izilinganiso zangempela zibonisa ukuthi ngaphansi kwezimo ezifanayo zokusebenza, ukusetshenziswa kwamandla kwemishini ye-granite base ku-8% -12% ephakeme kunaleyo yemishini yensimbi ekhonjiwe). Ukusetshenziswa isikhathi eside kuzonyusa izindleko zokukhiqiza.
Okwesihlanu, ikhono lokumelana nokushaqeka okushisayo lilinganiselwe
I-Core Drawback: Nakuba i-granite ine-coefficient ephansi yokunwetshwa kwe-thermal, ukuqhutshwa kwayo kwe-thermal kubi (ngokusebenza okushisayo okungu-1.5-3.0W/(m · K kuphela), cishe u-1/10 we-cast iron), kanye nokushintsha kwezinga lokushisa kwendawo okungazelelwe kujwayele ukukhiqiza ukucindezeleka okushisayo.
Umthelela kumishini ye-CNC:
Inkinga yomehluko wezinga lokushisa endaweni yokucubungula: Uma uketshezi olusikiwe luguguleka ngokugxilile indawo yasendaweni yetafula lokusebenza legwadle, lungabangela ukuthambeka kwezinga lokushisa (njengomehluko wezinga lokushisa ongu-5-10℃) phakathi kwale ndawo nendawo ezungezile, okuholela ekuwohlokeni okuncane kokushisa (inani lokuguquguquka lingafinyelela ku-1-3μm), okuthinta ukunemba kokucubungula kwegiya le-micro-stelency consinding
Ingozi yesikhathi eside yokukhathala okushisayo: Ezindaweni zeshabhu lapho kuqalwa khona futhi kuvalwe khona njalo noma umehluko omkhulu wokushisa phakathi kwemini nobusuku, izingxenye zegwadle zingase zibe nama-microcracks ngenxa yokunwetshwa okuphindaphindiwe nokufinyela okushisayo, kancane kancane kwenze buthakathaka ukuqina kwesakhiwo.
