Khoom noj khoom haus machinery hniav yog tsuas yog siv nyob rau hauv cov zaub mov ua machinery, feem ntau yog siv los txiav nqaij cov khoom, xws li: khov nqaij cov khoom, nqaij nyug thiab mutton, nqaij npua, thiab lwm yam. Khoom noj khoom haus garnish tuam txhab uas muag thiab lwm yam zaub mov industries kuj xav tau cov khoom no; Qee lub sij hawm muaj cov kev xav tau tshwj xeeb hauv cov txheej txheem ntawm kev ua zaub mov, nws yog ib qho tsim nyog yuav tsum tau ua ib lub voj voog los yog cov hniav ntev rau hauv cov hniav hniav (cov hniav hniav) xws li: round-toothed blades, ntev-toothed hniav, semi-circular-toothed. cov hniav thiab lwm yam qauv, cov hniav no yuav tsum tau muab cov duab kos los yog cov qauv rau kev tsim khoom thiab kev tsim khoom. Cov hniav nyiaj hniav kub yuav tsum muaj cov yam ntxwv ntawm kev ua kom zoo, ntse hniav, tsis muaj burrs, hnav tsis kam, du incision, thiab lub neej ntev. Tsuas yog los ntawm kev siv cov hniav zoo li no tuaj yeem txhim kho kev ua haujlwm hauv cov txheej txheem ntau lawm. Cov khoom lag luam ua cov hniav peb tsim tau lav tias yog cov hlau ntshiab, tsis muaj xeb, ntse thiab ruaj khov. Nyob rau tib lub sijhawm, German precision sib tsoo tshuab yog siv, qhov tseeb yog tswj los ntawm lub khoos phis tawj hauv cov txheej txheem tsim khoom, thiab kev kho cua sov siab siab tau txais, nrog qhov nruab nrab hardness.
