Tej yam khoom hardness najnpawb hlau
Nov 16, 2015
Cov xaiv los ntawm lub kaum sab xis ntawm lub cuab tam, koj ua tau ntau yam feem xyuam rau txoj, xws li cov khoom siv, tej khoom pab, cov ua khoom (roughing thiab xov), koj yuav tsum xaiv raws li qhov tsim nyog. Feem ntau uas ces kaum, lub kaum sab xis callout hais txog cov raug thiab yog ntsuas rau cov uas ua hauj lwm, vim tus plahaum qhov chaw txawv thiab qhov tej no lub cuab tam uas cob qhia hloov, lub kaum ntse ntse nyias thiab lub kaum sab xis ntawm lub callout tiag ua hauj lwm, tiam sis feem ntau tsawg.
Manufacturing tooling ntaub ntawv yuav tsum muaj siab kub hardness thiab hnav kuj, qhov tseem ceeb dabtsi yog khoov zog, toughness thiab tshuaj inertness, zoo technology (machining, forging, thiab kev kho cua sov), hab warp.
Feem ntau yog thaum cov ntaub hardness yog kub, coj kuj yog muaj flexural zog kub, toughness tej yam yog ntshav. Tab sis mus ntau dua cov hardness cov khoom, lub sab dabtsi yog khoov zog thiab feem toughness. High-speed tus hlau siab dabtsi yog khoov zog thiab toughness, thiab zoo machinability, Hyundai yog qhov tseem tseem lug siv pab khoom ntawd yuav nyuaj alloy.
Haum rau sau lo lus teb tej-hardness polycrystalline Boron Nitride tartar hlau thiab cam khwb cia hlau; pob zeb diamond polycrystalline rau machining ferrous tus hlau thiab alloys, uas thiab iav, cov tuam hlau thiab alloy tuam steel yog li tam sim no xwb xwb li ntaub ntawv, tuag thiab coj mus rhaub cov cuab yeej.
Carbide indexable cev ntas muaj tam sim no siv tshuaj vapor deposition txheej titanium carbide, Titanium Nitride, alumina txheej los ib txheej bacteria uas nyuaj. Yog tsis tsuas nrog rau txoj kev vapor lub cev deposition txujci rau cemented tuam carbide, kuj yuav siv tau rau kev kub ceev steel tej cuab yeej, khoom, hob, mills ub thiab kawg. Ua ib ntu los nyuaj coatings diffusion tshuaj thiab barrier tshav kub, ua tus coj cuab tam nyob rau cov tej slows coated hniav lub neej piv nrog cov txheej tsis yog li ntawm 1 txog 3 zaug dua los yog ntau tshaj.
