DIN333 HSSCO Center Drill Bits nrog TIN Txheej
FEATRUE
Kev ua haujlwm siab thiab tus nqi qis;
Lub hardness ntawm cobalt bearing center xyaum yog HRB: 66-68 degrees
Nws tuaj yeem ua kom tiav qhov kawg thiab qhov tseeb ntawm lub tshuab ua haujlwm
Nws tuaj yeem txiav tuag steel thiab stainless hlau nrog kev kho cua sov hardness ntawm 40 degrees
Lub neej kev pab cuam ntawm qhov chaw xyaum yog ntev, uas zoo heev txhim kho kev ua hauj lwm efficiency thiab txo tus nqi ntau lawm.
Nws tuaj yeem siv dav hauv ntau yam cuab yeej siv tshuab txiav
Nws tuaj yeem ntaus ntau tshaj 100 qhov hauv tsheb caij nplooj ntoos hlav steel phaj
M35 khoom, tuaj yeem ua cov hlau tsis muaj steel, tuag steel thiab lwm yam nyuaj rau kev ua cov hlau.M35 yog 5% cobalt uas muaj cov hlau ceev ceev.Piv nrog rau M35 cobalt uas muaj cov hlau ceev ceev, nws yog pheej yig thiab yooj yim rau txheej txheem.Los ntawm kev kho cua sov kom tsim nyog, nws tuaj yeem tau txais cov tawv tawv siab, siab tawv tawv thiab siab hnav tsis kam.Lub toughness thiab dabtsi yog khoov lub zog tsis yog qis dua li qub high-speed steel, uas muaj peev xwm kov yeej kev puas tsuaj thaum ntxov xws li tuag ntug vau thiab tawg.
