Uthini Umahluko phakathi kwe-SDS kunye ne-HSS Drill Bits?

Kukho izikolo ezibini zokucinga malunga nokuba imele ntoni na i-SDS - mhlawumbi yinkqubo yokuqhuba i-slotted drive, okanye isuka kwi-German 'stecken - drehen - sichern' - eguqulelwe njenge-'insert - twist - secure'.

Nantoni na echanekileyo - kwaye ingaba zombini, i-SDS ibhekisela kwindlela i-drill bit eqhotyoshelwe ngayo kwi-drill. Ligama elisetyenziselwa ukuchaza i-shank ye-drill bit - i-shank ibhekisela kwinxalenye ye-drill bit ekhuselwe kwisiqwenga sakho sesixhobo. Kukho iintlobo ezine ze-SDS drill bits esiza kuzichaza ngakumbi kamva.

I-HSS imele intsimbi enesantya esiphezulu, nto leyo esetyenziswa ukwenza amasuntswana okomba. I-HSS drill bits nayo inemilo ye-shanks emine eyahlukeneyo - ethe tye, ecuthiweyo, ecolekileyo, kunye ne-morse taper.

YINTONI UMAHLUKO PHAKATHI KWE-HDD NE-SDS?
Umahluko phakathi kwe-HSS kunye ne-SDS drill bits ibhekiselele kwindlela i-drill bit etyunjwa ngayo okanye ifakwe ngaphakathi kwe-drill.

HSS drill bits iyahambelana nayiphi na ichuck eqhelekileyo. I-HSS drill ineshanki ejikelezayo efakwe kwi-drill kwaye igcinwe kwindawo yayo yimihlathi emithathu eqinisa i-shank.

I-advanteji ye-HSS drill bits kukuba ifumaneka ngokubanzi kwaye inokusetyenziswa kwiindidi ezibanzi kakhulu zezicelo. Eyona nto ingalunganga kukuba i-drill bit ithanda ukukhululeka. Ngexesha lokusetyenziswa, i-vibration ikhulula i-chuck ethetha ukuba umqhubi kufuneka anqumame kwaye ajonge ukuqiniswa, okunokuba neempembelelo kumaxesha okugqiba umsebenzi.

I-SDS drill bit ayifuni kuqiniswa. Inokufakwa ngokulula nangokutyibilikayo kwindawo echongiweyo ye-SDS hammer drill. Ngexesha lokusetyenziswa, inkqubo ye-slot ikhusela kuyo nayiphi na i-vibration ukugcina ingqibelelo yokulungisa.

ZEZIPHI Ezona IINTLOBO EZQHUBEKAYO ZE-SDS DRILL BITS?
Ezona ndidi zixhaphakileyo zeSDS zezi:

I-SDS - i-SDS yoqobo enamanqina afakiweyo.
I-SDS-Plus - eguquguqukayo kunye ne-SDS drill bits rhoqo, inika uxhulumaniso olulula oluphuculweyo. Inamanqina ayi-10 mm aneendawo zokubeka ezine eziyibamba ngokukhuselekileyo.
I-SDS-MAX - I-SDS Max ine-shank enkulu ye-18mm eneendawo zokubeka ezintlanu ezisetyenziselwa imingxuma emikhulu. Ayitshintshi i-SDS kunye ne-SDS PLUS drill bit.
I-Spline – Ineshanki enkulu eyi-19mm kunye ne-splines ebamba amasuntswana aqine ngakumbi.
Izixhobo zikaRennie zinoluhlu olupheleleyo lwee-SDS drill bits ezinikezela ukusebenza okuphezulu. Umzekelo, i-SDS Pus i-masonry masonry drill drill bits yenziwa kusetyenziswa ingcebiso echasene noqhankqalazo eyenziwe nge-sintered carbide. Zikulungele ukubhobhoza ikhonkrithi, ibhloko, ilitye lendalo, kunye nezitena eziqinileyo okanye ezinemingxuma. Ukusetyenziswa kukhawuleza kwaye kukulungele - i-shank ingena kwi-chuck elula elayishwe entwasahlobo ngaphandle kwesidingo sokuqiniswa, evumela ukuba isilayidi ngasemva nangaphandle njengepiston ngexesha lokugaya. I-non-circular shank cross-section inqanda i-drill bit ekujikelezeni ngexesha lokusebenza. Ihamile ye-drill isebenza ukukhawulezisa kuphela i-drill bit ngokwayo, kwaye kungekhona ubunzima obukhulu be-chuck, eyenza i-SDS shank dill ibe nemveliso ngakumbi kunezinye iindidi ze-shank.

I-SDS Max Hammer Drill bit yinto eqiniswa ngokupheleleyo yehamile, inika enye yezona zinto zisebenza kakuhle ezikhoyo kwintengiso. I-drill bit igqitywe ngencam ye-tungsten ye-carbide yesiphambano sokugqibela ngokuchaneka kunye namandla. Ngenxa yokuba le SDS drill bit iya kungena kuphela koomatshini bokomba abane-SDS max chuck, sisixhobo esikhethekileyo sokuqhuba usetyenziso olunzima kwigranite, ikhonkrithi, kunye nokwakha.

EYONA IZICELO ZOKUGQIBELA I-HSS
I-HSS drill bits iyatshintsheka ngakumbi kuluhlu olubanzi lwezicelo. Ukusebenza okuphuculweyo kunye nomgangatho kufezekiswa ngokongezwa kweekhompawundi ezahlukeneyo ukunika ukusebenza okuphezulu. Ngokomzekelo, i-Rennie Tools HSS Cobalt Jobber Drill Bits yenziwe kwi-M35 edibeneyo ye-HSS yentsimbi kunye ne-5% ye-Cobalt umxholo, okwenza kube nzima kunye nokumelana nokunxiba. Zibonelela ngokufunxa ukothuka kwaye zinokusetyenziswa kwizixhobo zombane eziphathwa ngesandla.

Ezinye ii-HSS Jobber Drills zigqityezelwa ngomaleko we-oxide emnyama ngenxa yokuvutha komphunga. Oku kunceda ukutshabalalisa ubushushu, kunye nokuhamba kwetshiphu kwaye kubonelele ngepropathi yokupholisa kumphezulu wokomba. Le HSS drill bit yemihla ngemihla ibonelela ngowona msebenzi uphezulu womgangatho wokusetyenziswa kwemihla ngemihla ngamaplanga, isinyithi, kunye neplastiki.
