A rail sib tsoo logyog ib qho cuab yeej tshwj xeeb uas tsim los rau kev sib tsoo thiab ua tiav ntawm cov ntsia hlau. Nws muaj cov abrasive, bonding agent, thiab matrix. Lub abrasive yog lub hauv paus tseem ceeb ntawm lub log sib tsoo thiab feem ntau yog ua los ntawm cov ntaub ntawv nyuaj heev xws li pob zeb diamond, cubic boron nitride (CBN), corundum, thiab silicon carbide. Cov ntaub ntawv no muab lub log sib tsoo nws lub peev xwm sib tsoo muaj zog. Tus neeg sawv cev sib txuas ruaj khov khi cov abrasive ua ke, tswj kev ruaj ntseg ntawm lub log lub qauv thaum lub sij hawm siab -kev sib hloov ceev thiab sib tsoo. Lub matrix muab kev txhawb nqa rau tag nrho lub log sib tsoo, kom ntseeg tau tias nws tuaj yeem tiv taus ntau lub zog thaum ua haujlwm.
Nws txoj haujlwm ua haujlwm yog raws li lub hauv paus ntsiab lus ntawm kev sib txhuam kev sib tsoo. Thaum cov cuab yeej sib tsoo tsav tsheb sib tsoo lub log kom tig ntawm kev kub ceev, lub abrasive ntawm lub log nto tuaj rau hauv kev sib cuag nrog cov tsheb ciav hlau. Vim lub siab -kev sib hloov ceev ntawm lub sib tsoo log, ib tug loj kev sib txhuam quab yuam yog generated ntawm lub abrasive thiab rail. Qhov kev sib txhuam quab yuam no tuaj yeem kov yeej lub zog sib txuas ntawm cov khoom siv hauv tsheb ciav hlau, maj mam sib tsoo cov me me protrusions, tsis xws luag, thiab hnav khaubncaws sab nraud povtseg ntawm txoj kev tsheb ciav hlau. Thaum lub sij hawm kev sib tsoo, lub log sib tsoo yuav raug txiav cov tsheb ciav hlau raws li kev ua ntej - teeb tsa, xws li kev sib tsoo lub kaum sab xis, siab, thiab ceev, txhawm rau tshem tawm qhov tsis xws luag thiab rov ua kom lub geometry thiab smoothness ntawm txoj kev tsheb ciav hlau.
Raws li kev sib tsoo, kev sib txuas tus neeg sawv cev, thiab cov qauv tsim, rail sib tsoo log tuaj yeem muab faib ua ntau hom. Raws li cov abrasive, muaj pob zeb diamond log, CBN log, corundum log, thiab silicon carbide log, raws li tau hais ua ntej. Pob zeb diamond log, nrog rau lawv cov hardness tsis tshua muaj siab thiab hnav tsis kam, ua tau zoo nyob rau hauv kev sib tsoo zoo ntawm siab - nrawm, hnyav- thauj cov tsheb ciav hlau, tshem tawm cov khaubncaws sab nraud povtseg thiab qhov tsis xws luag los ntawm qhov chaw tsheb ciav hlau nrog kev sib tsoo siab, ua kom muaj kev pabcuam lub neej ntawm cov ntsia hlau. CBN log, nrog ib tug hardness thib ob rau pob zeb diamond, muaj zoo thermal stability thiab tshuaj inertness, muab tshwj xeeb zoo thaum sib tsoo siab -hardness alloy rails, txo lub log hnav thiab txhim kho kev sib tsoo efficiency. Corundum log muaj qhov zoo ntawm kev sib tsoo thiab kev sib tsoo, haum rau kev sib tsoo cov tsheb ciav hlau dav dav, thiab pheej yig heev. Silicon carbide log muaj qhov nyuaj me ntsis thiab pheej yig, feem ntau yog siv rau kev sib tsoo zoo tib yam, ua tau raws li cov kev xav tau sib tsoo yooj yim.
Los ntawm qhov kev xav ntawm tus neeg sawv cev sib txuas, ntau hom muaj xws li cob-cov log sib tsoo, ceramic- sib tsoo log, thiab hlau- sib tsoo log. Resin-bonded sib tsoo log muaj lub zog siab thiab zoo elasticity, zoo buffering sib tsoo quab yuam thaum sib tsoo thiab txo kev puas tsuaj rau cov ntsia hlau. Lawv kuj muaj tus kheej zoo-ntxhiab cov khoom, tswj kev sib tsoo zoo, thiab siv dav. Ceramic-bonded sib tsoo log muaj cua sov zoo, tshuaj lom neeg ruaj khov, thiab hnav tsis kam, ua rau lawv haum rau siab -precision, siab- kev sib tsoo ua haujlwm zoo, tab sis lawv cov nqi kuj yog siab heev. Hlau- sib tsoo lub log muaj kev sib raug zoo siab thiab hnav tsis kam, thiab feem ntau yog siv los tsim cov pob zeb diamond thiab CBN sib tsoo log kom tau raws li kev sib tsoo raws li kev ua haujlwm tshwj xeeb.
Tsis tas li ntawd, raws li lawv cov qauv tsim, rail sib tsoo lub log tuaj yeem raug categorized rau hauv cov log sib tsoo zoo tib yam, perforated sib tsoo lub log, thiab cov log sib tsoo. Cov qauv sib txawv ntawm kev sib tsoo cov log tsheb muaj cov yam ntxwv tshwj xeeb ntawm kev sib tsoo kev ua haujlwm, cua sov dissipation, thiab nti tuav, yoog rau ntau yam kev sib tsoo thiab hom kev tsheb ciav hlau tsis xws luag.
