Kev soj ntsuam ntawm cov yam ntxwv sib tsoo thiab cov txheej txheem tiav ntawm titanium rods
Ntawm cov kev siv dav ntawm titanium alloy cov ntaub ntawv, titanium rods yog qhov zoo tshaj plaws ntawm lawv, thiab lawv cov kev ua tau zoo yog ncaj qha ntsig txog kev ua tau zoo thiab cov tsos ntawm cov khoom kawg. Txhawm rau kom ua tiav qhov zoo nkauj ntawm titanium rods thiab cov qauv siab xws li H11, H9, H8, thiab H7, qhov tsis muaj qhov sib tsoo tau dhau los ua cov khoom siv tseem ceeb. Tsab ntawv xov xwm no yuav tshawb nrhiav qhov tob ntawm kev sib tsoo cov yam ntxwv ntawm titanium alloy rods ntawm qhov chaw tsis muaj kev sib tsoo, thiab yuav ua li cas kom ua tiav cov txheej txheem siab los ntawm kev ua kom zoo dua cov txheej txheem thiab cov khoom siv.
Qhov zoo ntawm centerless grinders
Lub tshuab tsis muaj zog tuaj yeem ua tiav kev sib tsoo zoo thiab raug nrog nws txoj kev ua haujlwm tshwj xeeb, uas yog, tsis tas yuav tsum muaj qhov chaw ua haujlwm axis. Cov cuab yeej muaj peb lub tshuab loj: sib tsoo lub log, hloov lub log, thiab kev txhawb nqa workpiece. Peb ua hauj lwm ua ke kom hloov tau yooj yim rau ntau yam kev xav tau. Tshwj xeeb tshaj yog rau cov ntaub ntawv muaj zog thiab siab hardness xws li titanium alloys, tsis muaj qhov sib tsoo tau pom muaj peev xwm ua tau zoo heev.
Tsib yam ntxwv ntawm titanium alloy sib tsoo
1. High hardness: Lub hardness ntawm titanium alloys feem ntau yog nyob nruab nrab ntawm HV350 thiab 400, uas ua rau muaj kev sib tw hnyav rau cov cuab yeej sib tsoo thiab ua rau cov cuab yeej poob thiab tawg.
2. Tsis tshua muaj thermal conductivity: Cov thermal conductivity tsawg ntawm titanium alloy ua rau cov cua sov sib sau sai heev thaum lub sij hawm sib tsoo, thiab nws nyuaj rau cov kua txiav tawm kom zoo, cuam tshuam rau qhov zoo ntawm lub tshuab ua haujlwm.
3. Ua rau oxidation: Nyob rau hauv qhov kub thiab txias ib puag ncig, titanium alloy yog yooj yim oxidized, cuam tshuam rau saum npoo zoo, thiab cov dej sib tsoo tsim nyog yuav tsum tau ua kom txias thiab lubrication.
4. Cov cuab yeej ua rau adhesion hnav: Kev sib txhuam ntawm lub log sib tsoo thiab cov titanium alloy generates kub, ua rau cov titanium alloy deform thiab ua raws li kev sib tsoo lub log, ua kom nrawm ntawm kev sib tsoo lub log.
5. Txias hardening tshwm sim: qhov kub siab generated los ntawm kev sib tsoo ua rau muaj tshuaj lom neeg cov tshuaj tiv thaiv nyob rau saum npoo ntawm titanium alloy, uas ua rau deg hardening thiab ua rau cov txheej txheem nyuaj.
Kev kos duab ntawm kev sib tsoo log xaiv
Raws li kev sib tsoo cov yam ntxwv ntawm titanium alloy, kev xaiv ntawm kev sib tsoo log yog qhov tseem ceeb. Silicon carbide sib tsoo lub log yog thawj qhov kev xaiv rau lawv cov hardness siab thiab hnav tsis zoo; thaum cubic boron nitride thiab polycrystalline pob zeb diamond yog dav siv nyob rau hauv high-end ua rau lawv kub tsis kam thiab siab stability. Kev xaiv ntawm cov khoom siv log sib tsoo no yog txhawm rau txo qhov sib tsoo kub thiab txhim kho kev sib tsoo zoo.
Qhov tseem ceeb ntawm coolant
Nyob rau hauv tus txheej txheem ntawm kev sib tsoo centerless, coolant tsis yog tsuas yog ib tug coolant, tab sis kuj yog ib tug tu tus neeg sawv cev. Nws yuav tsum muaj peev xwm tshem tawm cov cua sov sai sai thiab zoo ntxuav tawm cov xuab zeb zoo ntawm cov khoom thiab cov seem seem ntawm qhov sib tsoo lub log. Kev siv cov dej-soluble sib tsoo cov kua uas muaj ntau yam ntawm cov khoom siv siab heev tuaj yeem txhim kho kev ua haujlwm thiab txo qhov yuam kev.
Optimization ntawm kev sib tsoo tsis
Kev teeb tsa ntawm kev sib tsoo tsis muaj qhov cuam tshuam ncaj qha rau kev ua haujlwm zoo. Noj TC4φ10 titanium pas nrig ua piv txwv, los ntawm kev rov ua kev sim thiab kev ua tiav, peb tau txiav txim siab tias qhov kev sib tsoo zoo tshaj plaws yog 0.05 ~ 0.1mm thiab qhov pom kev sib tsoo log ceev yog 25m / s. Raws li qhov kev sib xyaw ua ke no, kev sib tsoo log adhesion yog qhov tsawg tshaj plaws thiab kev sib tsoo nto zoo tshaj plaws.
Nrog rau kev nthuav dav ntxiv ntawm daim ntawv thov kev lag luam ntawm titanium alloy cov ntaub ntawv, kev ua haujlwm raug thiab kev ua haujlwm ntawm titanium alloy tuav tau nce siab dua. Los ntawm kev ua kom zoo tsis tu ncua ntawm cov txheej txheem tsis tu ncua ntawm qhov tsis muaj qhov sib tsoo thiab xaiv cov kev sib tsoo uas tsim nyog thiab cov cua txias, peb tuaj yeem ua tiav kev ua haujlwm siab thiab ua haujlwm zoo ntawm titanium alloy tuav. Nyob rau hauv lub neej yav tom ntej, nrog rau kev nce qib ntawm cov cuab yeej technology thiab kev kho dua tshiab ntawm cov cuab yeej, peb muaj laj thawj ntseeg hais tias cov txheej txheem ntawm titanium alloy cov ntaub ntawv yuav ncav cuag ib theem tshiab.
