Lub tshuab txiav tuaj yeem muab faib ua tsib pawg raws li daim ntawv ntawm cov khoom ua haujlwm. Cov cuab yeej siv los txiav ntoo los ntawm ultrasonic slitter yog hu ua cov cuab yeej ua haujlwm ntoo. Cov ntaub ntawv tsis yog xim hlau puag ncig cov hniav no ua rau cov hniav slitter txiav ntawm qhov nrawm dua. Xyoo 1898, Taylor thiab Tebchaws Meskas. Dawb invented high speed steel. Cov ntaub ntawv tsim tawm ntawm kev xyaum twist tau sau tseg hauv xyoo 1822, tab sis nws tsis tau tsim los ua khoom muag kom txog rau thaum xyoo 1864. Raws li thaum ntxov 28th txog 20th centuries BC hauv Suav teb, cov laum thiab saws ntawm tooj liab cov cuab yeej xws li tooj dag tau tshwm sim thiab tooj liab cones, drills, thiab lwm yam. thiab saws.
Cov hniav ntawm lub slitter nyob rau lub sijhawm ntawd yog ua los ntawm cov cuab yeej carbon siab, thiab qhov tso cai txiav ceev yog li 5 meters / feeb. Xyoo 1923, Schleitel ntawm Lub Tebchaws Yelemees tau tsim cov cemented carbide. Vim hais tias cov slitter hniav siv hauv kev tsim khoom siv los txiav cov ntaub ntawv hlau, lo lus "riam" feem ntau nkag siab tias yog hlau txiav slitter hniav. Cov txheej txheem txheej txheej ua ke nrog lub zog siab thiab tawv ntawm cov khoom siv hauv paus nrog lub siab tawv thiab hnav tsis kam ntawm txheej txheej, kom cov khoom sib xyaw no muaj kev ua haujlwm zoo dua. Xyoo 1792, Mozley hauv tebchaws United Kingdom tsim cov kais dej thiab tuag.
Txawm li cas los xij, txoj kev loj hlob sai ntawm slitter hniav tuaj nyob rau hauv lub xyoo pua 18th nrog kev loj hlob ntawm cov cav tov thiab lwm cov cav tov.
Thaum siv cov cuab yeej hlau hlau, kev txiav ceev ntawm cov hniav slitter tau txhim kho txog li 8 meters ib feeb, thaum siv cov hlau ceev ceev, nws yog ntau dua ob npaug, thiab thaum siv cov hlau tawv tawv, nws yog ntau dua ob npaug ntawm kev siv cov hlau kub ceev. Qhov saum npoo zoo thiab qhov tseeb qhov tseeb ntawm cov khoom ua tiav los ntawm kev txiav kuj zoo heev.
Vim hais tias tus nqi ntawm high-speed steel thiab cemented carbide kuj kim heev, slitter hniav feem ntau welded thiab mechanically clamped. Xyoo 1972, General Electric tau tsim cov pob zeb diamond polycrystalline hluavtaws thiab polycrystalline cubic boron nitride hniav. Xyoo 1783, René hauv Fab Kis thawj zaug tsim lub tshuab txiav tshuab.
Slitting tshuab hniav yog cov cuab yeej siv rau kev txiav hauv kev tsim khoom, tseem hu ua txiav cov hniav. Txij xyoo 1949 txog xyoo 1950, Tebchaws Meskas tau pib siv cov khoom siv indexable ntawm cov cuab yeej tig, thiab tsis ntev los no siv rau milling cutters thiab lwm yam cuab yeej. Xyoo 1972, Bangsha thiab Laglan ntawm Tebchaws Meskas tau tsim ib txoj hauv kev rau lub cev vapor deposition txheej txheej txheej ntawm titanium carbide los yog titanium nitride rau saum npoo ntawm carbide los yog high-speed steel slitter hniav. Xyoo 1868, Mushete hauv tebchaws Askiv tau tsim cov cuab yeej hlau uas muaj tungsten. Cov cuab yeej siv rau kev ua ntau yam sab nraud, suav nrog cov cuab yeej tig, cov phiaj xwm, milling cutters, sab nrauv broaches thiab cov ntaub ntawv, thiab lwm yam .; cov cuab yeej ua lub qhov, suav nrog kev xyaum, reamers, tho txawv cov cuab yeej, reamers thiab sab hauv nto broaches, thiab lwm yam .; xov cov cuab yeej, suav nrog cov kais dej, tuag, tsis siv neeg qhib thiab kaw xov txiav taub hau, xov tig cov cuab yeej thiab xov milling cutters, thiab lwm yam.; iav ua cov cuab yeej, suav nrog hob, iav shaper, shaving cutter, bevel iav ua cov cuab yeej, thiab lwm yam .; thaiv cov cuab yeej, suav nrog cov ntawv ntxig Circular saw hniav, band saws, hneev saws, thaiv cov cuab yeej tig thiab pom cov hniav milling cutters, thiab lwm yam. Nyob rau hauv lub sijhawm tom qab ntawm Warring States Period (lub xyoo pua peb BC), vim yog cov tshuab carburizing, rab riam tooj liab tau tsim.
