Thetha malunga neHSS kunye neCarbide Drill Bits

Njengezona zinto zimbini zisetyenziswa kakhulu kwi-drill bits zezixhobo ezahlukeneyo, i-speed-speed steel drill bits kunye ne-carbide drill bits, zithini iimpawu zazo, ziziphi iingenelo kunye nokungalunganga kwazo, kwaye zeziphi izinto ezingcono xa zithelekiswa.
Isizathu sokuba i-speed-speed drill bits isetyenziswe ngokubanzi kukuba i-high-speed steel material inokumelana okuqinileyo nokushisa okuphezulu kunye nokumelana nokugqoka, kwaye ayiyi kuvelisa i-deformation kunye nemiphumo yokugqoka ngexesha lokusika ukushisa okuphezulu. Ewe kunjalo, iqinisekiswa kancinci ngokusetyenziswa kwexesha. Kuya kubakho ilahleko, kodwa izinto ezenziwa ngexesha ngaphandle kokumosha zixabiseke kakhulu. Okwesibini, ukuqina kwe-speed-speed drills kuphezulu kakhulu kunezinye izinto. I-drilling drills kufuneka ingagcini nje ukugcina uzinzo kunye neemfuno zokuqina. Ikwaphezulu kakhulu. Ngaphandle kokuqina okuhle, i-drill bit ithanda ukutshiphuza, nto leyo ekhokelela kwidayamitha yomngxuma engazinzanga xa i-drill bit igugile.
Inzuzo enkulu ye-carbide drills bubunzima babo obuphezulu. Inzuzo yobulukhuni obuphezulu ivumela i-carbide drills ukuba ijongane nezinye iintsimbi ezinobunzima obuphezulu. Nangona kunjalo, eyona nto ingalunganga kakhulu kwi-carbide drills kukuqina okungahambi kakuhle, okuncinci kakhulu kwaye kulula ukukrazula. Kwimeko yemingxuma enzulu, Ukuba akukho nkqubo ikhethekileyo njengenkxaso ye-carbide drill bit ikude nomphumo we-speed-speed drill bits, ngokuqinisekileyo, ukuqina kwe-speed-speed drill bits kunokumelana nayo.
Ngokubanzi, i-speed-speed steel drill bits kunye ne-carbide drill bits zineempawu ezifanayo, kodwa indawo ebalaseleyo yentsimbi yesantya esiphezulu ilele kubunzima obuhle, ngelixa indawo ebalaseleyo ye-carbide drill bits bubunzima obuphezulu, kunye nokwahlukileyo. izinto ezingeloncedo kukuba ubulukhuni bentsimbi ye-speed drill bits akwanelanga, kwaye i-high-hardness steel icutshungulwa.
Ayisiyi-resistant-resistant, kwaye ukuqina kwe-carbide drills yokucubungula imingxuma enzulu akulungile, ngoko xa ukhetha i-drill, kufuneka ukhethe i-drill ehambelanayo ngokwemeko ethile. Ngokomzekelo, i-speed-speed steel drills ezenziwe ngobhedu, isinyithi kunye ne-aluminium zifanelekile ngakumbi kune-carbide drills. I-DTH high-hardness carbide drill bit iya kuba yomelele ngakumbi kune-speed-speed steel drill bit.
