PAMUSORO PEZVIGADZIRWA
Madhiragi ePDC anoshandiswa pakuchera matsime emvura, kuchera geotechnical uye nharaunda, kutsvaga zvicherwa, matsime egethermal, kuchera geothermal, kuvaka uye mabasa ekushandisa.
Saizi Yakajairika: 56mm, 65mm, 75mm, 94mm, 113mm, 133mm, 153mm (2 inches kusvika 6 inches)
Bapiro/Chidimbu Huwandu: 3/4/5
Nyaya sezvakakumbirwa
Zvakanakira: Mucheka wePDC wemhando yepamusoro.
KUSHANDISA
Yakakodzera matombo akaomarara akapfava kusvika pakati nepakati (f=1-8), haawanikwe mumatombo akatyoka, akatyoka, uye akasimba.
Chinhu
Zvigayo zvemhando yepamusoro zvepolycrystalline diamond compact (PDC) semazino ekucheka, zvigayo zvine quanlity yakagadzikana, kushanda zvakanaka pakuboora, uye kushanda kwenguva refu. Unogona kusarudza mhando dzakasiyana dzezvigayo zvePDC zvichienderana nehunhu hwemaumbirwo azvo, uye kuderedza kushanda zvakanaka kwekuboora.
