Nyob rau hauv precision sib tsoo, lubvitrified daim ntawv cog lus sib tsoo logyog dav lees paub raws li tus qauv kev lag luam. Los ntawm bearing raceway sib tsoo thiab turbine hniav hauv paus machining mus rau hydraulic valve tiav thiab kev kho mob implant nto kho mob, nws yog siv nyob rau hauv txhua qhov chaw siab thiab zoo ib yam ntawm nto yuav tsum tau. Qhov laj thawj yog nyob rau hauv nws cov qauv kev sib txuas tshwj xeeb thiab kev ua haujlwm.
Qhov xwm ntawm Vitrified Bond: Ib khob-Phase Network Structure
Lub ntsiab tseem ceeb ntawm daim ntawv cog lus vitrified yog silicate iav. Thaum lub sij hawm siab - kub hnyiab, nws tsim ib lub iav txuas ntxiv -theem network ntawm cov nplej abrasive. Zoo ib yam li iav tsim, sib txawv oxides yaj thiab hnov mob los tsim kom muaj kev sib txuas txuas ntxiv. Tsis zoo li resin bonds, uas feem ntau yog nyob rau hauv lub cev adhesion, ib tug vitrified daim ntawv cog lus sib tsoo log kuj yuav tsim tshuaj bonds nrog tshwj xeeb kho abrasive nplej.
Cov qauv no muab kev sib raug zoo zog, zoo heev tshuaj lom neeg ruaj khov, thiab superior kub tsis kam. Lub vitrified daim ntawv cog lus sib tsoo log tseem ruaj khov siab dua 300 degree, thaum resin bonds feem ntau pib muag ntawm ib ncig ntawm 150 degree.
Tus kheej -Ntxhiab: Qhov Zoo Tshaj Plaws
Ib qho kev sib tw loj tshaj plaws hauv kev sib tsoo precision yog lub log dulling, uas ua rau muaj zog sib tsoo thiab tuaj yeem hlawv lub workpiece.
Lub vitrified daim ntawv cog lus sib tsoo lub log ib txwm daws qhov teeb meem no los ntawm tus kheej -sharpening. Raws li abrasive nplej ua npub, daim ntawv cog lus tawg thiab nthuav tawm cov ntse txiav tshiab. Piv nrog rau cov cob- cov log sib txuas, uas feem ntau xav tau kev hnav khaub ncaws tsis tu ncua, cov log vitrified muaj kev ruaj khov txiav kev ua tau zoo rau lub sij hawm ntev, xa cov kev sib tsoo ntau dua thiab zoo dua nto.
Tswj Porosity: Ntsuas Chip Clearance thiab Log Lub Neej
Lub vitrified daim ntawv cog lus sib tsoo lub log tuaj yeem tsim nrog kev tswj porosity. Cov pores no muab qhov chaw rau nti tshem tawm thaum uas tso cai rau cov cua txias thiab cua mus rau hauv qhov chaw sib tsoo, txhim kho cov cua sov.
Cov qib porosity sib txawv haum rau kev siv sib txawv. Tsawg porosity muab lub zog ntau dua rau hnyav- lub luag haujlwm sib tsoo, thaum porosity siab dua yog qhov zoo tagnrho rau kev sib tsoo ntawm nyias- phab ntsa lossis cua sov- qhov chaw nkag siab.
Rigid Bonding thiab Dimensional Stability
Lub siab rigidity ntawm vitrified daim ntawv cog lus txo qis elastic deformation thaum lub sij hawm sib tsoo, cia lub vitrified daim ntawv cog lus sib tsoo log kom muaj zoo profile raug. Qhov no ua rau nws tshwj xeeb tshaj yog haum rau daim ntawv thiab profile sib tsoo.
Nws lub siab hnav tsis kam thiab tsis tshua muaj thermal expansion kuj pab tswj qhov ntev ruaj khov thaum lub sijhawm ua haujlwm ntev, kom ntseeg tau qhov tseeb ntawm machining raug.
Lub vitrified daim ntawv cog lus sib tsoo log yog dav siv rau cov kabmob raceways, hydraulic Cheebtsam, iav hniav, txiav cov cuab yeej, thiab aerospace turbine hniav machining. Txawm li cas los xij, vim tias cov ntawv cog lus vitrified yog cov nkig, lawv tsis haum rau cov ntawv thov hnyav. Txoj kev hnav khaub ncaws kom zoo thiab xaiv cov coolant yuav tsum tau xav txog thaum siv.
Kev xaiv xaiv
Thaum xaiv lub vitrified daim ntawv cog lus sib tsoo lub log, tsom rau ntawm daim ntawv cog lus, porosity, abrasive type, thiab grit loj. Cov yam tseem ceeb no txiav txim siab hardness, tus kheej -sharpening peev xwm, nti clearance, sib tsoo efficiency, thiab nto tiav. Xaiv txoj kev sib xyaw ua ke rau daim ntawv thov yuav pab ua tiav cov txiaj ntsig zoo tshaj plaws.
