Lawv tau ua los ntawm DIN 1897 cov qauv kev lag luam (metric sizing), uas pab xyuas kom meej tias cov khoom siv tho thoob ntiaj teb, ua raws li cov lus qhia tib yam.
Lawv yog siv nyob rau hauv cov cav tov xws li handheld portable xyaum, xyaum presses, machining chaw, thiab lathes.Laum khoom tuaj nyob rau hauv ntau hom thiab ntev.
Ua raws li NAS 907 cov qauv, siv nyob rau hauv kev lag luam aerospace luv luv-ntev laum khoom, kom zoo dua rigidity thiab nce zog High-speed steel (HSS) uas muaj cobalt yog ib tug zoo ua ke ntawm toughness thiab hardness, siv rau drilling los ntawm cov khoom tawv kub oxide. , khaws cia txiav cov kua thiab tiv thaiv nti rau cov cuab yeej vuam 135-degree faib cov kaum sab xis, zoo rau cov khoom siv tawv, tawv
Nta
Qhov kev xyaum no muaj qhov tseeb hauv av profile, txoj cai txiav hom N thiab ib qho ntxiv luv luv cylindrical tsim.Nrog nws cov khoom siv HSS ua haujlwm siab thiab 135 ° tapered seem, cross-ground du nto tiav raws li DIN 1412 C (los ntawm 3.0 mm inch).
Daim ntawv thov
Rau nyias daim hlau, hlau thiab cam khwb cia hlau (alloyed thiab unalloyed, muaj zog mus txog 800 N / mm²), cam khwb cia hlau, malleable hlau, ductile hlau, luv-chip aluminium alloys, tooj liab, nyuaj tooj dag, tooj dag, tuag castings, thiab lwm yam.
Qhov zoo
Tshwj xeeb tshaj yog tsim rau tes tuav drilling rigs, ua tsaug rau tus kheej-centering laum tswv yim, uas ua kom meej meej coj drilling yam tsis tas siv lub hauv paus punch.
Peb tau tsom mus rau kev tshawb fawb, kev tsim kho, tsim khoom thiab muag ntawm HSS twist laum khoom.Peb muab ntau hom HSS twist xyaum cov khoom thiab cov kev qhia tshwj xeeb kom ua tau raws li cov qauv sib txawv, cov txheej txheem tshwj xeeb thiab cov kev xav tau ntawm tus kheej.Tshaj li 14 xyoo dhau los, peb tau txhim tsa lub koob npe zoo los ntawm peb cov kev siv zog tsis tu ncua.Peb cov khoom raug xa tawm mus rau Russia, Tebchaws Asmeskas, Lub Tebchaws Yelemees, Fabkis, Thaib, Nyab Laj, Brazil, Middle East thiab ntau lub tebchaws thiab cheeb tsam, thiab peb muab peb cov khoom rau cov khoom lag luam thoob plaws ntiaj teb.
