Qhov kev xyaum ua nruab nrab yog qhov twg thiab lawv yog dab tsi?

Lub chaw nruab ntug muaj rau ntau hom kev cob qhia, txij li thaum lawv siv feem ntau hauv cheeb tsam industrial. Lub ntsiab qhov txawv ntawm cov ntaub ntawv ntaus thiab cov niaj zaus yog nyob rau hauv qhov tseeb ntawm lub qhov yog drilled. Yuav ua li cas qhov kev xyaum ua nruab nrab raug teem thiab qhov uas lawv tau thov, koj yuav pom txoj cai tam sim no.

Nta ntawm cov khoom

Externally, qhov cuab yeej no yog ib qho kev me me ntawm qhov ntev me ntsis nrog ib qhov chaw tuab heev. Nyob rau hauv rooj plaub no, nws kab yuav 2-3 zaus lub dav ntawm ua hauj lwm ntxeev ntawm lub mechanism. Vim qhov tsim, qhov nruab nrab xyaum (GOST qhov kev lees paub) muaj kev yeem siab heev, yog li thaum drilling ib qhov, nws yuav luag tsis khoov nws los yog ua kom deform nws.

Qhov cuab yeej no ua haujlwm li cas?

Ua ntej, ib tug me me xyaum drills ib qhov ntawm me me lub cheeb. Nws, raws li txoj cai, yog tsim tom qab ob peb lub rotations ntawm qhov ntsuas (tsis pub ntau tshaj 2-3 seconds). Tom qab ntawd, qhov tsawg tshaj plaws qhov yog widened los ntawm kev txiav ntug ntawm cov khoom siv khov tuab ntawm kev xyaum. Nws yuav tsum tau sau tseg tias thaum lub tshuab no ua hauj lwm, lub perpendicularity ntawm tus zawj feem ntau rau cov khoom uas tau ua tiav thiab nws cov nplaum yog guaranteed.

Daim ntawv thov

Kev siv qhov nruab nrab yog siv rau kev siv ntoo thiab ntoo. Txawm li cas los, "raws li daim passport", uas yog, rau nws lub hom phiaj uas tau npaj, qhov cuab yeej no tsuas yog siv rau kev ua cov khoom steel. Txawm li cas los xij, qhov no tsis tiv thaiv peb cov neeg tsim khoom los siv nws ua tus xa khoom saum ntoo, piv txwv li, thaum nws tsim nyog yuav tob zuj zus rau lub qhov kev sib tw ntawm tus qauv. Vim nws txoj kev tiv thaiv ua kom sov thiab ua kom muaj zog, lawv yeej tsis poob qab tom qab ua cov khoom sib xws thiab cov khoom siv.

Xws li lawv cov hom phiaj ncaj qha, cov cuab yeej no yog siv rau cov tshuab drilling, drilling thiab tshuab dhos tshuab. Tsis tas li ntawd, kev xyaum siv lub cev kuj tuaj yeem siv tau rau hauv tsev neeg. Tseem nyiam siv tej khoom siv thiab xov tooj cua amateurs. Tej yuav tau xyaum yuav tsum tau ntau dua puas tau rau cov khoom qhov nyob rau hauv luam Circuit Court laug cam. Thiab txij li cov khoom siv tau muaj kev nruj heev (qhov no yog txiav txim tsis yog los ntawm lawv cov lus, tab sis kuj yog qhov tshwj xeeb ntsuas, uas peb tau tham yav dhau los), nws yooj yim thiab yooj yim rau kev ua hauj lwm nrog lawv.

Khoom siv

Cov lus sau ntawm cov cuab yeej no feem ntau muaj cov cuab yeej hlau ntawm P6M5 series. Tsis tas li ntawd, kev xyaum ua nruab siab tuaj yeem ua los ntawm kev kub ceev HSS. Tab sis tshwj xeeb tshaj yog nyob rau hauv qhuav ntawm cov cuab yeej ua los ntawm steel series P9, uas muaj ib tug loj cov ntsiab lus ntawm tungsten. Vim qhov no, cov khoom yuav ua tau ntau dua thiab ruaj khov.

Tus nqi ntawm kev xyaum ua qhov ncaj qha yog nyob ntawm lawv qhov ntev. Yog li, piv txwv li, tus me tshaj 1-millimeter li ntawm 15 rubles rau ib chav tsev. Cov hnyav loj tshaj plaws uas muaj lub voj voog ntawm 6.3 millimeters muaj nqis txog pua pua nqi.
