Indima ebalulekileyo ye-Chamfered Edges kwi-Precision Granite Platforms

Kwihlabathi le-metrology kunye nokudityaniswa okuchanekileyo, eyona nto iphambili ekugxilwe kuyo, ngokufanelekileyo, kukuthambeka kwendawo yokusebenza yeqonga legraniti. Nangona kunjalo, ukwenza ipleyiti yomgangatho ophezulu ngokwenene, ehlala ixesha elide, kunye nekhuselekileyo kufuna ingqalelo emaphethelweni-ngokukodwa, umkhuba wokuwajikeleza okanye ukuwajikeleza.

Ngelixa ingachaphazeli ngokuthe ngqo i-sub-micron yokuchaneka kwenqwelomoya esebenzayo, umphetho we-chamfered luphawu oluyimfuneko oluphucula ngokubonakalayo ubude bepleyiti, ikhusela izixhobo zokulinganisa ezixabisekileyo, kwaye iqinisekisa ukhuseleko lwegcisa. Yinto ebalulekileyo yokwenziwa kwegranite yanamhlanje, yobuchwephesha.

Imfuneko Yokwaphula Umda

Kutheni abavelisi besusa ngabom ikona ebukhali, 90∘ apho umphezulu wokusebenza udibana nobuso obusecaleni be slab ye granite? Ifikelela kwizizathu ezithathu ezingundoqo: ukuqina, ukhuseleko, kunye nokusebenza.

1. Ukuthintela iChipping kunye nomonakalo

Igranite inzima ngendlela emangalisayo, kodwa obu bunzima benza ukuba umphetho obukhali, ongaxhaswanga ube brittle kwaye ube sengozini yokuqhekeka. Kwilebhu exakekileyo yokuvelisa okanye yokulinganisa, intshukumo ayitshintshi. Ukuba igeyiji enzima, into enye, okanye isixhobo singqubeka ngengozi kwikona ebukhali, engalungiswanga, impembelelo inokubangela ukuba itshiphu yophuke lula.

• Ukukhusela uTyalo-mali: Umphetho ojikelezileyo (okanye ongqukuva/ojikelezisiweyo) udala indawo eyomeleleyo, ethambekileyo yesithinteli. Lo "mphetho owaphukileyo" usasaza ngempumelelo iimpembelelo zengozi kwindawo enkulu yomphezulu, inciphisa ngokumangalisayo ukuxinana koxinzelelo kunye nomngcipheko wokuqhekeka. Ukukhusela umda kuthetha ukukhusela ingqibelelo yesakhiwo kunye nexabiso lobuhle beplate yonke.
• Ukuthintela iiBurrs: Ngokungafaniyo nentsimbi, i-granite ayiphuhlisi i-burrs, kodwa i-chip okanye i-nick inokudala indawo engalinganiyo enokuthi idibanise amalaphu okucoca okanye ibe yingozi. Umphetho ongqukuva unciphisa le migca yempazamo enokwenzeka.

2. Ukuphucula uKhuseleko loMsebenzisi

Ubunzima obuninzi kunye nokubukhali, imiphetho yendalo ye-slab enkulu yegranite ibeka ingozi enkulu. Ukuphatha, ukuthuthwa, kunye nokusebenza ecaleni kwepleyiti engafakwanga i-chamfered kuyingozi.

• Ukuthintela Ukwenzakala: Umphetho obukhali, ogqitywe kakuhle wegranite unokusika okanye ukukrwela igcisa. Ukuqhekeka komphetho kukuqala kunye nokuphambili kumlinganiselo wokhuseleko, ukususa amandla okulimala ngexesha lokumisela, ukulinganisa, kunye nokusetyenziswa kwansuku zonke.

3. Ukuphucula ubomi obude bokusebenza

I-Chamfering inceda ekusetyenzisweni ngokubanzi kunye nokugcinwa kwepleyiti. Iququzelela ukunyakaza okugudileyo kwezikhuselo kunye nezixhobo kunye nokwenza lula ukusetyenziswa kweengubo zokukhusela okanye i-edge tape. Umphetho ococekileyo, ogqityiweyo luphawu lwesixhobo semetrology yodidi lobungcali.

Ukukhetha iNgcaciso eLungileyo: R-Radius vs. Chamfer

Xa uchaza unyango olusemaphethelweni, abavelisi basebenzisa igama leradiyasi, elifana ne-R2 okanye i-R3 (apho 'R' imele iRadius, kwaye inani liyimilinganiselo yeemilimitha). I-chamfer, okanye "i-bevel," ngokobuchwepheshe i-flat, i-angled cut, kodwa amagama asetyenziswa ngokungafaniyo ukubhekisela kuwo nawuphi na umgca ophukileyo. Kwigranite echanekileyo, iradiyasi engqukuva idla ngokukhethwa kuxhathiso oluphezulu lwetshiphu.

Ukuqonda i-R2 kunye ne-R3

Ukhetho lweenkcukacha, olufana nerediyasi ye-R2 okanye i-R3, ngokuyintloko ngumbandela wesikali, ubuhle, nokuphatha.

• I-R2 (I-Radius 2 mm): Le yiradiyasi eqhelekileyo, efihlakeleyo, kunye nesebenzayo, ehlala isetyenziswa kwiipleyiti zokuhlola ezincinci, ezichane kakhulu. Inika ukhuseleko olwaneleyo kunye nokukhuselwa kwetshiphu ngaphandle kokulawula ngokubonakalayo.
• I-R3 (iRadiyosi 3 mm): Iradiyasi enkulu kancinane, i-R3 inika ukhuseleko olongeziweyo kwiimpembelelo ezinzima. Ihlala icaciswa kwiitheyibhile ezinkulu zomphezulu, ezifana nezo zisetyenziswa ngaphantsi koomatshini bokulinganisa i-Coordinate (CMMs) okanye ezinye izixhobo ezinzima, apho umngcipheko wempembelelo yecala ngengozi uphezulu.

Iradiyasi ayilandeli umgangatho woshishino olungqongqo (njengamabakala amcaba e-ASME) kodwa ikhethwa ngumvelisi ukuze ilungelelane nobungakanani bepleyiti ngokubanzi kunye nendawo yokusebenza ecetywayo. Kwigranite echanekileyo yomgangatho omkhulu, ukuqinisekisa ukuba umphetho we-R3 ongaguquguqukiyo, omenyezeliswe kakuhle lutyalo-mali ekuzinzeni kwexesha elide kunye nokhuseleko lomgangatho weevenkile.

Ekugqibeleni, iinkcukacha ezincinci zomphetho werediyasi ye-R luphawu olunamandla lokuzibophelela komenzi kumgangatho odlulela ngaphaya komphezulu wokusebenza osicaba, eqinisekisa ukuba iqonga lilonke liyomelele, likhuselekile, kwaye lakhiwe ukuba lihlale.
