1, kev yuav khoom ntawm CNC hniav cov tub lag luam tau ntxhov siab los ntawm kev hnav ntawm CNC hniav, abrasive hnav chips lossis qee cov ntsiab lus nyuaj me me rau ntawm qhov chaw ua haujlwm (xws li carbide, oxide, thiab lwm yam) thiab impurities (xws li xuab zeb, oxide. , thiab lwm yam), raws li zoo raws li qhov adhesion ntawm cov nti qog cov khib nyiab, thiab lwm yam, ib qho khoom siv coj los ntawm cov grooves carved rau saum npoo ntawm CNC hniav.Rau cov cuab yeej siv high-speed steel uas tsis tshua muaj kev cia siab thiab qis txiav kub (xws li broach, tuag, kais, thiab lwm yam), nws yog qhov tseem ceeb tshaj plaws ntawm kev hnav.
2. Adhesive hnav cov ntaub ntawv tshiab nto tiv tauj nyob rau hauv qhov zoo siab thiab txiav kub nruab nrab ntawm lub nraub qaum lub ntsej muag ntawm CNC hniav thiab lub workpiece nto thiab lub ntsej muag lub ntsej muag ntawm CNC hniav thiab cov chips.Thaum qhov chaw sib cuag mus txog qhov sib nrug deb, qhov adsorption bond tshwm sim tshwm sim.Cov taw tes sib koom ua ke maj mam txiav thiab rhais tawm los ntawm cov khoom ua haujlwm lossis cov chips, thiab qhov chaw ntawm CNC hniav yuav tsim cov nplaum hnav.Adhesive hnav yog ib qho laj thawj tseem ceeb rau kev hnav ntawm cemented carbide thaum txiav ntawm nruab nrab thiab qis txiav ceev.
3, diffusion hnav ntawm qhov kub thiab txias, siab siab, CNC hniav cov khoom thiab cov khoom siv ua haujlwm hauv cov khoom hauv lub xeev ntawm qee cov tshuaj lom neeg hauv kev sib tshuam me me, uas yog, tungsten carbide Ti, w, Co thiab lwm yam zoo li steel diffusion, thiab workpiece Fe, C thiab lwm yam rau CNC hniav diffusion, ua rau lub hardness ntawm lub cuab tam nto, muaj zog nyeem ntawv poob, brittleness nce, cuab yeej siv intensification.Qhov no yog hu ua diffusion hnav, thiab diffusion hnav yog ib qho laj thawj tseem ceeb rau kev hnav cov cemented carbide txiav cov cuab yeej thaum kub kub (800 "900 ° C).
4, feem ntau W, Co diffusion tus nqi nrawm dua Ti, Ta, yog li qhov kub kub txiav kev ua tau zoo ntawm YT chav kawm cemented carbide zoo dua YG chav kawm.Theem hloov hnav Thaum txiav nrog cov cuab yeej siv high-speed steel, thaum txiav kub siab tshaj qhov hloov pauv kub (550 "600 ° C), cov qauv metallographic ntawm CNC hniav yuav hloov, kom lub hardness yuav txo thiab hnav yuav nrawm. , yog li cov theem hloov hnav yog ib qho ntawm cov laj thawj tseem ceeb rau kev hnav ntawm high-speed steel CNC hniav.Kev siv tshuaj lom neeg ntawm qhov kub thiab txias, cov xov xwm nyob ib ncig ntawm thaj chaw txiav, xws li huab cua, txiav cov kua dej, thiab lwm yam, ua rau muaj tshuaj lom nrog cov cuab yeej siv los tsim qee cov khoom tawg thiab tawg.Cov tebchaw no yooj yim raug txiav thiab ua haujlwm ua haujlwm tawg, ua rau CNC hniav hnav.
