Iibhithi ze-HSSCO zokubhola iNyathelo zokubhola isinyithi

Iidrill zestep step zentsimbi ezikhawulezayo zisetyenziselwa ukubhola iipleyiti zentsimbi ezibhityileyo ngaphakathi kwe-3mm. I-drill bit enye ingasetyenziswa endaweni yee-drill bits ezininzi. Imingxuma yeedayamitha ezahlukeneyo ingacutshungulwa njengoko kufuneka, kwaye imingxuma emikhulu ingacutshungulwa ngexesha elinye, ngaphandle kwesidingo sokutshintsha i-drill bit kunye ne-drill positioning holes. Okwangoku, i-integral step drill yenziwe nge-CBN all-grinding. Izixhobo ikakhulu zi-high-speed steel, i-cemented carbide, njl.njl., kwaye ukuchaneka kokucubungula kuphezulu. Ngokweemeko ezahlukeneyo zokucubungula, unyango lwe-surface coating lunokwenziwa ukwandisa ubomi benkonzo yesixhobo kunye nokuphucula ukuqina kwesixhobo.
