Kwizixhobo zokulawula amanani ze-CNC, nangona i-granite iye yaba yinto ebalulekileyo ngenxa yeempawu zayo ezizodwa, iingxaki zayo ezisisiseko zinokuba nefuthe elithile ekusebenzeni kwezixhobo, ukusebenza kakuhle kokucubungula kunye neendleko zokulungisa. Oku kulandelayo luhlalutyo lweempembelelo ezithile ezibangelwa ziintsilelo ze-granite ezivela kwiinkalo ezahlukeneyo:
Okokuqala, izinto ezisetyenzisiweyo zibuthathaka kakhulu kwaye zinokwaphuka kwaye zonakale
Isiphene esingundoqo: I-Granite lilitye lendalo kwaye ngokusisiseko lilitye elibuthathaka kwaye linobunzima obuphantsi bokuchaphazeleka (ixabiso lokuqina kokuchaphazela limalunga ne-1-3J/cm², eliphantsi kakhulu kune-20-100J/cm² yezinto zesinyithi).
Impembelelo kwizixhobo ze-CNC:
Iingozi zokufakelwa kunye nezokuthutha: Ngexesha lokuhlanganiswa okanye ukuphathwa kwezixhobo, ukuba zichaphazeleka okanye ziwiswe, izinto zegranite (ezifana neziseko kunye neereyile ezikhokelayo) zinokuba neentanda okanye iikona eziqhekekileyo, nto leyo ekhokelela ekungachaneki kokuchaneka. Umzekelo, ukuba iqonga legranite lomatshini wokulinganisa onamakhonkco amathathu livelisa iintanda ezifihlakeleyo ngenxa yokusebenza okungafanelekanga ngexesha lokufakelwa, kunokukhokelela ekuwohlokeni kancinci kancinci kokusila xa kusetyenziswa ixesha elide, okuchaphazela iziphumo zokulinganisa.
Iingozi ezifihlakeleyo kwinkqubo yokucubungula: Xa izixhobo ze-CNC zidibana nomthwalo omninzi ngequbuliso (njengokungqubana kwesixhobo nomsebenzi), iireyile zesikhokelo segranite okanye iitafile zokusebenza zinokuphuka ngenxa yokungakwazi ukumelana namandla okuchaphazeleka ngoko nangoko, okubangela ukuba izixhobo zivalwe ukuze zilungiswe, kwaye zide zibangele uthotho lokusilela kokuchaneka.
Okwesibini, ubunzima obukhulu bokucubungula buthintela uyilo lwezakhiwo ezintsonkothileyo
Iingxaki eziphambili: I-Granite inobunzima obuphezulu (6-7 kwisikali se-Mohs), kwaye kufuneka igutywe kwaye icutshungulwe ngezixhobo ezikhethekileyo ezifana namavili okugaya idayimani, nto leyo ebangela ukuba ukusebenza kwayo kube kuphantsi (ukusebenza kakuhle kokugaywa yi-1/5 ukuya kwi-1/3 kuphela yezinto zesinyithi), kwaye iindleko zokucubungula iindawo ezigobileyo ezintsonkothileyo ziphezulu.
Impembelelo kwizixhobo ze-CNC:
Imida yoyilo lwesakhiwo: Ukuze kuthintelwe ubunzima bokucubungula, izinto zegranite zihlala ziyilwe ngeemilo zejiyometri ezilula (ezifana neepleyiti, iireyile zesikhokelo eziziingxande), okwenza kube nzima ukufikelela kwimingxuma yangaphakathi enzima, iipleyiti eziqinileyo ezikhaphukhaphu kunye nezinye izakhiwo ezinokufezwa ngokuphosa/ukusika ngezinto zesinyithi. Oku kukhokelela kwinto yokuba ubunzima besiseko segranite budla ngokuba bukhulu kakhulu (10%-20% bubunzima kunesinyithi esityhidiweyo kwivolumu efanayo), nto leyo enokunyusa umthwalo wonke wezixhobo kwaye ichaphazele ukusebenza kwempendulo eguquguqukayo ngexesha lokuhamba ngesantya esiphezulu.
Iindleko eziphezulu zokugcinwa nokutshintshwa: Xa kusenzeka umonakalo okanye ukuguguleka kweendawo zegranite, kunzima ukuzilungisa ngeendlela ezifana nokuwelda okanye ukusika. Ngokwesiqhelo, yonke into kufuneka itshintshwe, kwaye izinto ezintsha kufuneka ziphinde zigaywe kwaye zilinganiswe ukuze zichaneke, nto leyo ebangela ukuba ixesha elide lokungasebenzi (ukutshintshwa kube kanye kungathatha iiveki ezi-2-3), kunye nokunyuka okukhulu kweendleko zokugcinwa.
Iii. Ukungaqiniseki koBume beNdalo kunye neziphene zangaphakathi
Isiphene esingundoqo: Njengeminerali yendalo, igranite ineemingxunya zangaphakathi ezingalawulekiyo, iimbobo okanye ukungcola kweeminerali, kwaye ukufana kwezinto zemithambo eyahlukeneyo kuyahluka kakhulu (ukuguquguquka koxinano kunokufikelela kwi-±5%, ukuguquguquka kwe-elastic modulus ±8%).
Impembelelo kwizixhobo ze-CNC:
Umngcipheko wokuzinza ngokuchanekileyo: Ukuba indawo yokucubungula yecandelo iqulethe iimfanta zangaphakathi, ngexesha lokusetyenziswa ixesha elide, iimfanta zinokwanda ngenxa yoxinzelelo, nto leyo ebangela ukuguquka kwendawo kwaye ichaphazele ukuchaneka kwezixhobo. Umzekelo, ukuba iireli zesikhokelo segranite zomatshini wokusila we-CNC zinemingxuma yomoya efihliweyo, zinokuwa kancinci kancinci phantsi kokungcangcazela okuphezulu, nto leyo ekhokelela kwimpazamo enkulu yokuthe tye kweereli zesikhokelo.
Umahluko ekusebenzeni kweqela: Izinto zegranite ezivela kwiibhetshi ezahlukeneyo zinokufumana utshintsho kwizalathisi eziphambili ezifana ne-coefficient of thermal expansion kunye nokusebenza kwe-damping ngenxa yomahluko kulwakhiwo lweeminerali, oluchaphazela ukuhambelana kokuveliswa kweqela ngezixhobo. Kwimigca yemveliso ezenzekelayo efuna ukusebenzisana kwezixhobo ezininzi, umahluko onjalo unokukhokelela ekwandeni kokusasazeka kokuchaneka kokucubungula.
Okwesine, inzima, nto leyo echaphazela ukusebenza okuguquguqukayo kwezixhobo
Ingxaki engundoqo: I-Granite inobunzima obuphezulu (2.6-3.0g/cm³), kwaye ubunzima bayo buphindwe kayi-1.2 kunobentsimbi ephoswe ngesinyithi kunye nobunzima obuphindwe kayi-2.5 kunobe-aluminium alloy phantsi komthamo ofanayo.
Impembelelo kwizixhobo ze-CNC:
Ukulibaziseka kwempendulo yokunyakaza: Kwiziko zoomatshini abasebenza ngesantya esiphezulu okanye koomatshini abane-axis ezintlanu, ubunzima obukhulu besiseko segranite buya kwandisa i-inertia yomthwalo we-linear motor/lead screw, nto leyo ekhokelela ekulibazisekeni kwempendulo eguquguqukayo ngexesha lokukhawulezisa/ukunciphisa isantya (okunokunyusa ixesha lokuqalisa nge-5% ukuya kwi-10%), okuchaphazela ukusebenza kakuhle kokucubungula.
Ukusetyenziswa kwamandla okongeziweyo: Ukuqhuba izinto zegranite ezinzima kufuna ii-servo motors ezinamandla ngakumbi, nto leyo enyusa ukusetyenziswa kwamandla ngokubanzi kwezixhobo (imilinganiselo yokwenyani ibonisa ukuba phantsi kweemeko ezifanayo zokusebenza, ukusetyenziswa kwamandla kwezixhobo zesiseko segranite kuphezulu nge-8%-12% kunezixhobo zesinyithi esityhidiweyo). Ukusetyenziswa kwexesha elide kuya kunyusa iindleko zemveliso.
Okwesihlanu, amandla okumelana noxinzelelo lobushushu anqongophele
Isiphene esingundoqo: Nangona i-granite inomlinganiselo ophantsi wokwanda kobushushu, ukuhanjiswa kwayo kobushushu kuphantsi (ngomlinganiselo wobushushu we-1.5-3.0W/(m · K) kuphela, malunga ne-1/10 yentsimbi ephosiweyo), kwaye utshintsho olukhawulezileyo lobushushu lwendawo lunokubangela uxinzelelo lobushushu.
Impembelelo kwizixhobo ze-CNC:
Ingxaki yokwahluka kobushushu kwindawo yokucubungula: Ukuba ulwelo lokusika lutshabalalisa indawo yendawo yetafile yokusebenza yegranite, lunokubangela i-gradient yobushushu (njengokwahluka kobushushu obuyi-5-10℃) phakathi kwale ndawo nendawo ejikelezileyo, nto leyo ekhokelela ekuguqukeni kobushushu okuncinci (ubungakanani bokuguquguquka bunokufikelela kwi-1-3μm), nto leyo echaphazela ukuchaneka kokucutshungulwa ngokuchanekileyo (njengokugrinda kwegiya kwinqanaba le-micron).
Umngcipheko wokudinwa bubushushu bexesha elide: Kwiindawo zokusebenzela apho ii-startups zihlala zivaliwe okanye umahluko omkhulu kubushushu phakathi kwemini nobusuku, izinto zegranite zinokuba nemifantu emincinci ngenxa yokwanda nokuncipha kobushushu okuphindaphindiweyo, nto leyo ebangela ukuba ubulukhuni besakhiwo bube buthathaka kancinci kancinci.
