Uhlelo lwe-BTA (Boring & Trepanning Association) lwasungulwa kakhulu iqembu lamazwe ngamazwe labakhiqizi bamathuluzi.Lolu hlelo lwalungezinye zezinhlelo zokuqala eziyimpumelelo zamathuluzi okukhipha ama-chip angaphakathi, futhi luhlanganisa ukubhoboza, ukucikeka, kanye nekhanda elicijile futhi libhekwa njengohlelo olungcono kakhulu lomsebenzi wokwenza imigodi olusebenzisa amathuluzi okupholisa ngomfutho ophezulu.
Enqubweni yokwenza imbobo yesistimu ye-BTA, uketshezi olungaphansi kwengcindezi lugeleza luye onqenqemeni lokusetha phezu kwe-OD yebha eyisicefe nekhanda, futhi kuphelelwa amandla ngama-chips nge-ID yebha eyisicefe.Uketshezi oluhlungiwe oluhlanzekile lugeleza njalo ngaphandle kwekhanda, ngaleyo ndlela lugcoba amaphedi omhlahlandlela asebenza njengethuluzi elishisayo ukuze akhiqize isiphetho esibushelelezi, futhi akwazi izinga eliphezulu lokuphakela.Ukujula kwembobo kutholakala okungamadayamitha angu-150 noma ngaphansi.
1. Ikhwalithi ephezulu kanye nentengo yokuncintisana
2. Ukulethwa kwezimpahla ngesikhathi
Leli khanda lokubhoboza le-BTA lithatha i-indexable coating blade engenisiwe, linenzuzo yokusebenza kahle okuphezulu, i-blade yokushintsha kalula, impilo ende yesevisi, izindleko eziphansi zokusebenzisa.Futhi ingabhoboza nge-carbon steel, i-alloy steel enamandla amakhulu, insimbi engagqwali nokunye.ukunemba kobubanzi bomgodi IT9-11.Ubulukhuni bobuso: Ra6.3-12.5
