I-Granite straightedge yi "benchmark engabonakaliyo" yokuqinisekisa ukuchaneka kwimigca yokuvelisa izixhobo zoomatshini.

I-Granite straightedge yi "benchmark engabonakaliyo" yokuqinisekisa ukuchaneka kwimigca yokuvelisa izixhobo zoomatshini. Iingqwalasela eziphambili zichaphazela ngokuthe ngqo ukuzinza komgca wemveliso yonke kunye nezinga lokufaneleka kwemveliso, ezibonakaliswa ikakhulu kule milinganiselo ilandelayo:
"Ukungabinandawo" kwereferensi echanekileyo
Ukufakwa kunye nokugunyaziswa kwezikhokelo zesixhobo somatshini kunye neetafile zokusebenza kumgca wokuvelisa kufuneka zisekelwe ngokuthe ngqo (≤0.01mm / m) kunye ne-parallelism (≤0.02mm / m) ye-granite straightedge. Impahla yayo yendalo ephezulu (3.1g / cm³) inokugcina ukuchaneka ixesha elide, kunye ne-coefficient yokwandisa i-thermal ye-1.5 × 10⁻⁶/℃ kuphela. Kungakhathaliseki ukuba ubukhulu beqondo lokushisa kwi-workshop inkulu kangakanani, ayiyi kubangela ukuba ireferensi itshintshe ngenxa "yokwandiswa kwe-thermal kunye ne-contraction" - oku "kuzinza" abalawuli besinyithi abanako ukufezekisa, ukuphepha ngokuthe ngqo iimpazamo zendibano yezixhobo ezibangelwa izikhombisi ezingachanekanga.
2. I-"Durability Game" ye-Anti-vibration kunye ne-Wear Resistance
Indawo engqongileyo yomgca wemveliso intsonkothile, kwaye iqhelekile ukuba iifayili zokupholisa kunye nentsimbi zitshize. Ukuqina okuphezulu kwegranite (nobulukhuni be-Mohs be-6-7) buyenza ikwazi ukumelana nokukrweleka kwaye ayiyi kuhlwa okanye ibotshwe ziifayili zentsimbi njengerula yentsimbi. Kwangaxeshanye, inokufunxeka okuqinileyo kwendalo. Ngexesha lokulinganisa, kunokunciphisa ukuphazamiseka kwe-vibration okubangelwa ukusebenza kwesixhobo somatshini, ukwenza ukufundwa kwe-vernier caliper kunye nesalathisi sokudayela kuzinzile kwaye siphephe ukuphambuka komlinganiselo obangelwa kukugqoka isixhobo.

lexile Uqhelaniso" ukwenzela iimeko
Imigca yemveliso eyahlukeneyo ineemfuno ezahlukeneyo zobude kunye nebakala elichanekileyo lerula:

Kwiindawo ezincinci zemigca yokuvelisa, khetha irula ye-0-grade enobubanzi be-500-1000mm, elula kwaye ihlangabezana nemigangatho echanekileyo.
Imigca yokuhlanganisa izixhobo zomatshini onzima zifuna i-2000-3000mm 00-grade iirula ezithe tye. Uyilo lomphezulu osebenza kabini lwenza ulungelelwaniso lwangaxeshanye lokuhambelana kweereyile zesikhokelo eziphezulu nezisezantsi.

4. "Ixabiso elifihliweyo" loLawulo lweeNdleko
Umlawuli we-granite ophezulu unokuhlala iminyaka engaphezu kwe-10, eneendleko eziphezulu kwixesha elide kunomlawuli wensimbi (kunye nomjikelezo wokutshintshwa kweminyaka emi-3 ukuya kwemi-5). Okona kubaluleke ngakumbi, kunokunciphisa ixesha lokulungiswa kwezixhobo ngokusebenzisa ulungelelwaniso oluchanekileyo. Umzi-mveliso othile wezixhobo zemoto wabika ukuba emva kokusebenzisa iirula zegranite, ukusebenza kakuhle kotshintsho lwemodeli yokuvelisa kunye nokulungiswa kweempazamo kwanda ngama-40%, kwaye izinga le-scrap lehla ukusuka kwi-3% ukuya kwi-0.5%. Esi sisitshixo "ekugcineni imali kunye nokuphucula ukusebenza kakuhle".

Kwimigca yemveliso, abalawuli begranite abakho nje izixhobo ezilula zokulinganisa kodwa "ngabagcini-masango abachanekileyo". Ukukhetha okulungileyo kuqinisekisa ukuzithemba komgangatho womgca wonke. Zizixhobo ezibalulekileyo zokulinganisa igranite kwimizila yemveliso echanekileyo
