Umbhobho we-drill we-HDD ukhethwa yimathiriyeli yombhobho we-drill, imilo yecandelo elinqamlezayo, ubungakanani bejometri, kunye nobude benkcazo.Ikhethwa ngokobukhulu bomsebenzi wempembelelo ye-rock drill, iqondo lokuthamba kunye nokuqina kwelitye, ububanzi bentloko yoqheliso, ubunzulu bomngxuma wamatye, iimfuno zokudityaniswa kwelitye elisetyenziselwa i-drill tail shank, kunye nendlela yokutya ye-rock drill.
Ngokuqhelekileyo phantsi kwesiseko sokuhlangabezana neemfuno zokugaya, iibhobho zokubhobhoza kunye ne-moderate cross-section, ubunzima bokukhanya, ubude obufutshane, ukuqina okulungileyo kunye nobomi obude kufuneka kukhethwe kangangoko kunokwenzeka. Uqhagamshelo lwe taper kunye namacandelo anqamlezayo anehexagonal akhethwa ngokubanzi.Ubungakanani bomsila we-drill yi-108mm x H22 kwaye i-material yi-55SiMnMo, 95CrMo, njl njl. Kwi-flat-layini yokwembiwa kunye nokugrumba amatye, i-H25, i-H28, i-H32, kunye ne-H35 i-hexagonal cross-section threaded connections with the diameter efanayo, ukunciphisa ububanzi. kunye neentonga zokubhola ezikhawulezayo zikhethwa ngokubanzi.Ukwenzela imveliso yokomba amatye (imigodi engaphantsi komhlaba kunye nemingxuma evulekileyo), i-D35, D38, D45, D51, D60, D65, D76, kunye ne-D87 i-cross-sections cross-sections, i-threaded connections of the ubukhulu obufanayo, ukucutha ubukhulu, kunye neentonga zokubhola ezitshintsha ngokukhawuleza kunye nemibhobho yokubhobhoza zikhethwa ngokubanzi.
Umgaqo wokukhetha ubude benkcazo kukuba: kunqunywe ngokweemfuno zobunzulu bokomba, ngokubanzi kwi-0.3-7.3 Ngaphakathi koluhlu lwe-mm.
