Ungakhetha njani phakathi kwesarha esiqhelekileyo sokusika isinyithi kunye nesarha ebandayo ejikelezayo?

Kwiivenkile ezininzi zokusebenza ngentsimbi, xa usika isinyithi, ukukhetha i-saw blade kunokuba nefuthe elikhulu ekusebenzeni kakuhle nasekusemgangathweni. Ukwenza ukhetho olungalunganga kuyayonakalisa imveliso yakho yexesha elifutshane. Ekugqibeleni, kunokunciphisa amathuba akho okufumana abathengi abafuna ukusika okuthile kwizinto ezithile.

Ukuze ukwazi ukwenza ukhetho olufanelekileyo, kufuneka wazi iingenelo kunye nokungalungi kweeblade zesarha ebandayo kunye neeblade zesarha ezisikiweyo rhoqo.

Yintoni isarha ebandayo

Iisarha ezibandayo zisebenzisa i-blade yesarha esijikelezayo ukusika iintlobo ngeentlobo zeentsimbi eziquka i-sheet metal. Njengoko igama lisitsho, i-cold saw yenza umsebenzi wayo ngempumelelo, ngelixa ithintela zombini i-blade kunye ne-metal ukuba zingatshi kakhulu. Iisarha ezibandayo zihlala zingoomatshini abazimeleyo kwaye azizo iintlobo eziphathwayo.

Ngumatshini wokusika osetyenziselwa ukusika isinyithi ngesantya esiphezulu ngaphandle kokudala ubushushu obugqithisileyo, iintlantsi okanye uthuli. Ukusarha okubandayo kusebenzisa iblade ejikelezayo ukususa izinto ngelixa udlulisela ubushushu obuvelisiweyo kwiitships ezenziwe yiblade yesarha. Ubushushu obuveliswa ngexesha lokusikwa ngesarha ebandayo budluliselwa kwi-burrs ezenziwe endaweni yezinto ezisikiweyo, ngaloo ndlela umsebenzi uhlala ubanda.

Isarha ebandayo isebenzisa ibhlede yentsimbi eqinileyo enesantya esiphezulu (HSS) okanye ibhlede ye-tungsten carbide-tipped (TCT) ejika ngesantya esiphantsi se-RPM.

Ngokuchasene negama, iiblayidi ze-HSS azisetyenziswa rhoqo ngesantya esiphezulu kakhulu. Endaweni yoko, uphawu lwazo oluphambili bubulukhuni, obuzinika ukumelana nobushushu nokuguguleka, ukumelana nokuguguleka kwangaphambi kwexesha okunokuchaphazela ukugqitywa kweendawo ezisikiweyo. Iiblayidi ze-TCT zibiza kakhulu kodwa ziqinile kakhulu kwaye ziyakwazi ukusebenza kumaqondo obushushu aphezulu kune-HSS. Oku kuvumela iiblayidi zesarha ze-TCT ukuba zisebenze ngokukhawuleza kuneeblayidi ze-HSS, nto leyo enciphisa kakhulu ixesha lokusikwa.

Iingenelo Zokusebenzisa I-Cold Saw

Iisarha ezibandayo zingasetyenziselwa ukusika iimilo ezahlukeneyo, kuquka iintonga, iityhubhu, kunye nee-extrusions. Iisarha ezibandayo ezijikelezayo nezizenzekelayo zisebenza kakuhle kwimisebenzi yemveliso kunye neeprojekthi eziphindaphindayo apho ukunyamezelana nokugqitywa kubalulekile. Ezi matshini zibonelela ngesantya esiguquguqukayo seeblade kunye namazinga okutya ahlengahlengiswayo kwimveliso ekhawulezayo kunye nokusika okuchanekileyo okungenazo ii-burr.

Iisarha ezibandayo, ngeencakuba zazo ezinamazinyo, zenza iziqwenga ezicocekileyo ngaphandle kwemiphetho eqhekekileyo. Nangona iincakuba ezirhabaxa zihlala zihambahamba, nokuba zinqumle ngokuthe tye, iincakuba ezinamazinyo zithembeke ngakumbi kwiziqwenga ezithe tye okanye ezigobileyo. Ngencakuba elungileyo nebukhali, isarha ebandayo ejikelezayo ekhawulezayo ineengenelo zokuphelisa phantse iincakuba kwaye ingavelisi sparks, discolor, okanye dust. Ke, le ndlela ngokubanzi inika ukugqitywa komgangatho ophezulu kunye nemiphetho yokwenyani. Kwakhona azingcolisi kangako ngaphandle kothuli olurhabaxa olungena kuyo yonke into ekwindawo yayo.

Inkqubo yokusarha okubandayo iyakwazi ukukhupha amandla aphezulu kwiintsimbi ezinkulu nezinzima — kwiimeko ezithile, nokuba ziqine njenge ±0.005” (0.127 mm). Iintsimbi ezibandayo zingasetyenziselwa ukunqumla iintsimbi zentsimbi nezingeyontsimbi, kunye nokusika okuthe tye nokugobileyo. Umzekelo, iintlobo eziqhelekileyo zentsimbi zivumela ukusarha okubandayo, kwaye zinokusikwa ngokukhawuleza ngaphandle kokudala ubushushu obuninzi kunye nokungqubana.

Ungonga imali ngesarha ebandayo

Nangona ixabiso lokuqala le-cold saw blade linokuba phezulu kune-abrasive disc, ungayilola kwakhona i-carbide-tip blade izihlandlo ezininzi, nto leyo eyenza ukuba wonge kakhulu. I-cold saws ikwagcina ixesha nemali ngokwenza ukusika okuchanekileyo.

Ezi zicucu zingenasiphako azifuni msebenzi wesibini wokugqiba, nto leyo esindisa umsebenzi ongakumbi kwiimeko ezininzi. Izicucu ezichanekileyo zisengenye inzuzo njengoko iisarha ezisikiweyo zinokubamba ukunyamezelana okusondeleyo, kwakhona zisusa umsebenzi obizayo wobukhulu besibini.

Ngaba isarha ebandayo yindlela efanelekileyo yokusebenzisa intsimbi yakho yokusika?

Ngaphambi kokuba ukhethe ukusarha okubandayo ukuze unqumle inxalenye yesinyithi, kubalulekile ukuqonda iingenelo kunye nokungalungi kwenkqubo. Ngale ndlela, unokuvavanya kwaye ugqibe ukuba ingaba - okanye nayiphi na enye indlela yokusika isinyithi echanekileyo onokuyicinga - iya kuhlangabezana neemfuno zakho kunye nezinto eziza kuqala kuwe.

Iingxaki Zokusebenzisa I-Cold Saw

Nangona kunjalo, ukusarha ngokubandayo akulunganga kubude obungaphantsi kwe-0.125” (3.175 mm). Ukongeza, le ndlela inokuvelisa ii-burrs ezinzima. Ngokukodwa, yingxaki apho une-ODs ezingaphantsi kwe-0.125” (3.175 mm) nakwii-IDs ezincinci kakhulu, apho ityhubhu iya kuvalwa yi-burr eveliswe yi-cold saw.

Enye ingxaki ngee-cold saws kukuba ubulukhuni benza ii-saw blades zibe buthathaka kwaye zibe sengozini. Naluphi na ungcangcazelo — umzekelo, ngenxa yokungabambeki ngokwaneleyo kwenxalenye okanye izinga lokutya elingalunganga — lunokonakalisa amazinyo e-saws ngokulula. Ukongeza, ii-cold saws zihlala zibangela ilahleko enkulu ye-kerf, nto leyo ethetha ukulahlekelwa yimveliso kunye neendleko eziphezulu.

Nangona ukusarha okubandayo kungasetyenziswa ekusikeni uninzi lwee-alloys ze-ferrous kunye ne-non-ferrous, akukhuthazwa kwiintsimbi eziqinileyo kakhulu - ngakumbi ezo zinzima kunesarha ngokwayo. Kwaye nangona ii-cold saws zinokwenza ukusika okuhlanganisiweyo, zinokukwenza kuphela ngeenxalenye ezincinci kakhulu zobubanzi kwaye kufuneka i-fixturing ekhethekileyo.

Iibhleyidi zesarha zesinyithi eziqhelekileyo:

1. Indlela yokusika: Iiblayidi zesarha zentsimbi ezisetyenziswa rhoqo, kwelinye icala, zihlala zisebenzisa amazinyo entsimbi arhabaxa okanye akhawulezayo ukusika isinyithi. Ezi blayidi zivelisa ubushushu obuninzi ngexesha lenkqubo yokusika, nto leyo enokubangela ukubola kunye nokuguquguquka kobushushu besixhobo somsebenzi.

2. Ukuhambelana kwezinto: Iiblade zesarha zentsimbi ezisetyenziswa rhoqo zifanelekile ekusikeni iintsimbi ezithambileyo ezifana nentsimbi ethambileyo, isinyithi esityhidiweyo kunye nezinye izinto ezifanayo. Ezi blade zihlala zisetyenziswa kwimveliso ngokubanzi kunye nezicelo zokwakha apho ukusika ngokuchanekileyo kungengombandela uphambili.

3. Ubomi beblade: Iiblade zesarha ezisikwa rhoqo zentsimbi zinokuguguleka ngokukhawuleza ngenxa yobushushu obuphezulu obuveliswa ngexesha lenkqubo yokusika. Ke ngoko, zinokufuna ukutshintshwa rhoqo, ingakumbi xa zisetyenziselwa imisebenzi enzima yokusika.

4. Isantya sokusika kunye nokusebenza kakuhle: Iiblade zesarha zokusika zentsimbi eziqhelekileyo zaziwa ngesantya sazo sokusika esiphezulu, nto leyo ezenza zifaneleke ukunqunyulwa okukhawulezayo, okurhabaxa kwiintsimbi zentsimbi. Nangona kunjalo, ubushushu obuveliswa ngexesha lenkqubo yokusika bunokuchaphazela umgangatho wokunqunyulwa kwaye kunokufuneka ukugqitywa okongezelelweyo ukuze kufezekiswe isiphumo esifunekayo.

ukuququmbela:

Ngamafutshane, ukhetho phakathi kweeblayidi zesarha ezibandayo kunye neeblayidi zesarha zentsimbi eziqhelekileyo luxhomekeke kwiimfuno ezithile zokusetyenziswa kokusika isinyithi. Iiblayidi zesarha ezibandayo zilungele ukunqumla iintsimbi ezingezizo ezentsimbi ngokuchanekileyo, zibonelela ngokusika okucocekileyo, okungenazimbombo kwaye zandise ubomi beblayidi. Iiblayidi zesarha zentsimbi eziqhelekileyo, kwelinye icala, zilungele ukunqumla okukhawulezayo, okurhabaxa kwiintsimbi zentsimbi, nangona zinokufuna iinkqubo ezongezelelweyo zokugqiba. Ukuqonda umahluko phakathi kwezi ntlobo zimbini zeeblayidi zesarha kubalulekile ekukhetheni ukhetho olufanelekileyo kumsebenzi othile wokusika isinyithi.

Khangela isarha ebandayo ejikelezayo ukuba umsebenzi wakho:

• Usika izinto ezingezizo ezinkulu kakhulu
