Ma Drill Bits a DIN333 HSSCO Center okhala ndi TIN Coating

Kuchita bwino kwambiri komanso mtengo wotsika;

Kuuma kwa cobalt bearing center drill ndi HRB: madigiri 66-68

Zingatsimikizire kuti pamwamba pake pali kulondola komanso kulondola kwa chogwirira ntchito chopangidwa ndi makina

Imatha kudula chitsulo chosapanga dzimbiri ndi chitsulo chosapanga dzimbiri chokhala ndi kuuma kwa kutentha kwa madigiri 40

Moyo wa ntchito ya center drill ndi wautali, zomwe zimapangitsa kuti ntchito igwire bwino ntchito komanso kuchepetsa ndalama zopangira.

Itha kugwiritsidwa ntchito kwambiri mu zida zosiyanasiyana zamakina odulira

Imatha kuboola mabowo opitilira 100 mu mbale yachitsulo yamasika yamagalimoto

Zipangizo za M35, zimatha kukonza chitsulo chosapanga dzimbiri, chitsulo chofewa ndi zina zovuta kukonza zitsulo. M35 ndi chitsulo chofewa cha 5% chokhala ndi cobalt chothamanga kwambiri. Poyerekeza ndi cobalt ya M35 yokhala ndi chitsulo chofewa kwambiri, ndi yotsika mtengo komanso yosavuta kukonza. Kudzera mu chithandizo choyenera cha kutentha, imatha kukhala yolimba kwambiri, yofiira kwambiri komanso yolimba kwambiri. Kulimba ndi mphamvu yopindika sizotsika kuposa chitsulo chofewa wamba chothamanga kwambiri, chomwe chingagonjetse kuwonongeka koyambirira monga kugwa kwa m'mphepete mwa mphika ndi ming'alu.
