Lawv tau ua raws li DIN 1897 cov qauv kev lag luam (metric sizing), uas pab ua kom ntseeg tau tias cov laum thoob ntiaj teb, ua raws li cov lus qhia tib yam.
Lawv siv rau hauv cov tshuab xws li cov tshuab xuas tes nqa tau, cov tshuab nias xuas, cov chaw ua haujlwm, thiab cov tshuab dhos. Cov ntsis xuas muaj ntau hom thiab qhov ntev.
Ua raws li NAS 907 tus qauv, siv rau hauv kev lag luam aerospace Cov ntsis laum luv luv, rau kev ruaj khov zoo dua thiab muaj zog dua Cov hlau ceev ceev (HSS) uas muaj cobalt yog kev sib xyaw zoo ntawm kev tawv thiab kev nyuaj, rau kev siv rau kev tho los ntawm cov khoom tawv Kub oxide, khaws cov kua txiav thiab tiv thaiv kev vuam chip rau cov cuab yeej 135-degree split point angles, zoo rau cov khoom tawv, tawv
Cov yam ntxwv
Lub tshuab laum no muaj qhov profile hauv av uas raug, txiav sab xis hom N thiab tsim lub cylindrical luv dua. Nrog nws cov khoom siv HSS ua tau zoo thiab 135° tapered section, qhov tiav du ntawm av hla raws li DIN 1412 C (txij li 3.0 hli txoj kab uas hla).
Cov ntawv thov
Rau cov phaj nyias, hlau thiab cov hlau cam khwb cia (alloyed thiab unalloyed, lub zog txog li 800 N/mm²), hlau cam khwb cia, hlau malleable, hlau ductile, luv-chip txhuas alloys, tooj liab, tooj dag tawv, tooj dag, tuag castings, thiab lwm yam.
Qhov zoo
Tshwj xeeb tshaj yog tsim rau cov tshuab drilling uas tuav tes, ua tsaug rau lub taub hau laum uas tig rau hauv nruab nrab, uas ua rau muaj kev laum qhia meej heev yam tsis tas siv lub tshuab ntaus nruab nrab.
Peb tau tsom mus rau kev tshawb fawb, kev txhim kho, kev tsim khoom thiab kev muag khoom ntawm HSS twist drill bits. Peb muab ntau yam khoom siv HSS twist drill thiab cov lus qhia kom ua tau raws li cov qauv sib txawv, cov txheej txheem tshwj xeeb thiab cov kev xav tau ntawm tus kheej. Tau 14 xyoo dhau los, peb tau tsim lub koob npe zoo los ntawm peb txoj kev siv zog tsis tu ncua. Peb cov khoom raug xa tawm mus rau Russia, Tebchaws Meskas, Lub Tebchaws Yelemees, Fabkis, Thaib, Nyab Laj, Brazil, Middle East thiab ntau lub tebchaws thiab thaj chaw, thiab peb muab peb cov khoom rau cov npe nrov thoob plaws ntiaj teb.
