Inkqubo ye-BTA (Boring & Trepanning Association) yaphuhliswa kakhulu liqela lamazwe ngamazwe labavelisi bezixhobo.Le nkqubo yayiyenye yeenkqubo zokuqala eziyimpumelelo zezixhobo zangaphakathi zokususa itshiphu, kwaye ibandakanya ukubhola, ukukruqula, kunye nentloko ye-trepanning kwaye ithathwa njengeyona nkqubo ilungileyo kumsebenzi wokwenza umngxuma osebenzisa izixhobo zokupholisa uxinzelelo oluphezulu.
Kwinkqubo yokwenziwa komngxuma we-BTA, ulwelo oluphantsi koxinzelelo luqukuqela ukuya kumda wokusetwa ngaphezulu kwe-OD yebhari ekruqulayo kunye nentloko, kunye nokukhupha iitshiphusi nge-ID yebhari ekruqulayo.Ulwelo olucociweyo olucociweyo luhamba rhoqo ngaphandle kwentloko, ngaloo ndlela luthambisa iipadi zesikhokelo ezisebenza njengesixhobo esitshisayo ukuvelisa ukugqiba okugudileyo, kwaye okukwaziyo ukondla izinga eliphezulu.Ubunzulu bomngxuma bufumaneka ukuya kuthi ga kwi-150 yedayamitha okanye ubunzulu.
1. Umgangatho ophezulu kunye nexabiso lokukhuphisana
2. Ukuhanjiswa kwempahla ngexesha
Le ntloko ye-BTA ye-drill yamkele i-indexable blade yokwambathisa, inenzuzo yokusebenza okuphezulu, i-blade yokutshintsha ngokulula, ubomi benkonzo ende, ixabiso eliphantsi lokusebenzisa.Kwaye inokugrumba kwintsimbi yekhabhoni, intsimbi yealloy yamandla aphezulu, intsimbi engenasici njalo njalo.ukuchaneka kwedayamitha yomngxuma IT9-11.Uburhabaxa bomphezulu: Ra6.3-12.5
