Hom Khoom Thiab Yam ntxwv Ntawm Hlau Drawing Tuag
Tso lus
Hlau kos tuag yog tsim los ntawm ntau yam khoom siv, feem ntau suav nrog pob zeb diamond, cemented carbide, polycrystalline pob zeb diamond (synthetic pob zeb diamond), CVD pob zeb diamond, ceramic, thiab hlau tuag.
Ntuj pob zeb diamond hlau daim duab tuag muaj siab hardness thiab zoo hnav tsis kam, tab sis yog nkig, tsis tshua muaj neeg ua haujlwm nyuaj, thiab kim tshaj plaws. Vim lawv cov anisotropy, lawv nquag hnav hnyav, thiab yog li ntawd feem ntau tsuas yog tsim nyog rau kev ua cov xov hlau nrog me me diameters.
Cemented carbide dies muaj qhov zoo xws li polishability zoo, tsis tshua muaj adhesion, tsis tshua muaj coefficient ntawm kev sib txhuam, thiab siab corrosion kuj, tab sis lawv hardness kuj tsawg, lawv hnav tsis zoo, thiab lawv lub neej luv luv. Lawv tuaj yeem siv los kos cov xov hlau ntawm ntau lub diameters.
Polycrystalline pob zeb diamond (synthetic pob zeb diamond) tuag muaj ib tug hardness thib ob rau tej pob zeb diamond thiab yog isotropic, tiv thaiv qhov tshwm sim ntawm ceev radial hnav. Txawm li cas los xij, lawv kim heev, nyuaj rau kev ua haujlwm, thiab muaj cov nqi tsim khoom siab.
CVD pob zeb diamond hlau daim duab tuag muaj qhov hnav zoo heev vim yog cov khoom ntawm pob zeb diamond, ua rau qis nto roughness, siab smoothness, thiab kub tsis kam nyob rau hauv cov xov hlau. Txawm li cas los xij, lawv cov txheej txheem tsim khoom yog complex, nyuaj rau txheej txheem, thiab kim.
Ceramic tuag muaj zog dua thiab hnav tsis kam tshaj li cemented carbide tuag thiab pheej yig los tsim, ua rau lawv cov khoom zoo heev ntawm pob zeb diamond thiab cemented carbide. Txawm li cas los xij, vim lawv tsis muaj zog, tsis zoo thermal poob siab, thiab kev ua haujlwm nyuaj, ceramics tsis tau ua tiav daim ntawv thov dav.
Steel tuag yog ib qho yooj yim los kho thiab pheej yig, tab sis lawv hardness thiab hnav tsis kam yog qhov tsis zoo, ua rau lub neej luv luv. Lawv feem ntau yog siv rau qis - ntim ntawm cov loj -section profiles.
Kev xaiv ntawm cov khoom siv hlau kos duab yuav tsum tau sib phim nrog cov yam ntxwv xws li hom kos hlau, kev ua haujlwm ntawm cov roj nplua nyeem, qhov tuag qhov aperture zoo, thiab cov cua txias kom ntev lub neej kev pab cuam.
