Izinto eziyinhloso zokulinganiswa kwe-RPM kumthethoselo wokugcina iquartz

Incazelo nezinhlelo zomshilo zokulinganiswa kwe-RPM

Ukufakela i-RPM kusho ukuthi kufanele isipiniyeli sezimboni sibe nezindiza ngokulinganayo no-rotation per minute (RPM) abalungiswa ngalo ubude bezibhade zediamond. Kungani lokhu kubaluleke? Lokho, lezi zibhade zenzelwe ngokusebenzisa izixwayiso ezithile kanye nendima yezigaba ezenza umsebenzi wabo ngaphandle kwamandla aphakeme. Uma sikhuluma ngaphezu kwebala eliphakeme le-RPM lebhadi, likhazimula kakhulu ikore ye-steel kanye nale zigaba ze-diamond. Kungani lokho kuthola? Izigaba mhlawumbe zingahlaziyeka, ikore ingasinda, noma ekugcineni konke, into yonke ivalelwa. Ngokwesinye isikhathi, uma usebenzisa phansi kwebala elideleke le-RPM, akusayi kwenzeke—ngempela. Izigaba azizange zifinyelele kwi-quartz kahle, ngakho esekela kumsebenzi wokugaya, okwakhiwa kakhulu kumthubi, ukugaya, kanye nokuhlukunyezwa kwezibhadi ngokushesha kunemva kokuba. I-quartz inamathambo amaningi, okuyisandla emhlabeni futhi yinto enqoba kakhulu. Ngakho-ke ukulahlwa kwebala kuthinta kakhulu izixhobo ngemuva kwesikhathi. Ukulungisa i-RPM ayisiyona kuphela ukulandela izici; kunciphisa abasebenzi ngexhumo njengoko kunciphisa isikhathi sokwenza umsebenzi.

Kungani umsindle waphandle (sfpm), engakhethiwe ukuguquka kwegolide ye-spindle, okuchaza iqiniso lekhiye kwesilika

I-Spindle RPM yithatha konke ukuvumelana, kodwa uma kufika ekugcineni kwesiqhamo, okubaluleke ngempela kukhona i-surface feet per minute (sfpm), okusenzo kukhona ukukhathaza ubude bokuchasene kwegilasi nesiqhamo. Ukufundwa lokhu, ukhuluma pi ngaphandle kwe-diameter yegilasi ngaphandle kwe-RPM kwaye wayehlukule ngubudaka. Lokhu kusinika ispeedi esiqobo ngaphandle kwegilasi. I-silica ibalulekile ngokugcwele kwaye yinkimbinkimbi, ngakho ke ukufumana i-sfpm ngendima ibaluleke kakhulu. Abantu anjalo abanjalo abafuna ukuba bahlale phakathi kwe-9,000 ne-11,000 sfpm ukuzivikela kwezinqumula ezincane zikwenzeka okanye ukugcina kwezinto ngokwenza kwezinto. Ngokomdla, igilasi e-14 inches ekrankayo ng-2000 RPM. Lokhu kusinika ngokwengekho 7,300 sfpm, okungaphakade kakhulu ukuba kwenzezwe izinto ezihle. Kodwa ukuba unike i-RPM eyi-3000, sikhona ngendima ye-11,000 sfpm, apho apho ngaphakathi kwezinto ezihle. Khumbula, ngoba i-sfpm ibaluleke kwe-RPM neyobude bwegilasi, wonke umntu ohlaneyo izixhobo kufuneka akwazi ukubala lokhu ngalinye ukuba angafundi ngokuphela ng-RPM ukuba ufuna iziphumo ezilungile kwaye igilasi elide.

Iziphumo zokungabi namandla amaphuremu ekusebenzisweni kwequartz

Ubude bokuphila kwebhledha nobuchwepheshe obutsha besegimenti ngokunzima kakhulu noma okuncane kwesfpm

Isivinini sangaphandle sokudluliswa kwezinto ezikhulayo ngasinye sezinqunywa, esilinganiselwe ngamathimbiti ngosuku oluthile (sfpm), kuyakha konke lokusebenza kwazo ngezintfo zeqoqo. Uma isfpm iphinde iphinde ngaphezu kwalokho okuthulwe, izinto zizodla kakhudlwana. Umphumulo ophakeme kunalezo ezindlini njengezindlela eziphazanyayo kuzophazanya izinto zomkhondo futhi kuzophazanya izinkunkuma ngaphambi kokusasa kubo.
