Hauv kev sib tsoo nto, kev xaiv kom zoo ntawm covnto sib tsoo logNws yog ib qho tseem ceeb kom ua tiav ob qho tib si machining efficiency thiab workpiece zoo. Thaum sib tsoo lub voj voog ntawm kev sib tsoo, feem ntau pom zoo kom siv qhov sib tsoo ntawm qhov sib tsoo. Cov nplej loj feem ntau yog nyob ntawm F36 txog F60, thiab qib hardness yog xaiv ntawm H thiab L kom ntseeg tau tias hnav tsis kam thiab tus kheej -ntxhiab muaj peev xwm.
Thaum sib tsoo nrog lub ntsej muag kawg ntawm lub ntsej muag sib tsoo, qhov chaw sib cuag ntawm lub log thiab cov khoom ua haujlwm yuav loj dua. Qhov no ua rau muaj teeb meem hauv kev khiav tawm ntawm cov nti thiab ua kom muaj cua sov ntau ntxiv. Yog li ntawd, nyob rau hauv xws li mob, cylindrical los yog ntxig nto sib tsoo log hom siv resin daim ntawv cog lus yog nyiam. Lawv cov nplej loj yog feem ntau coarser, xws li F20 txog F36, nrog rau qib hardness ntawm J thiab L, uas pab txhim kho cov cua sov dissipation thiab txo thermal puas rau lub workpiece.
Xaiv qhov sib tsoo
(1) Kev sib hloov ceev ntawm qhov sib tsoo lub log:
Lub peripheral ceev yuav tsum tau xaiv raws li cov khoom siv log, hom ntawv cog lus, thiab cov khoom siv ua haujlwm. Kev nrawm nrawm yog li ntawm 20 mus rau 35 m / s rau kev siv ntau dua, thaum siv ceev dua tuaj yeem siv nrog cov log tshwj xeeb.
(2) Longitudinal feed rate ntawm worktable:
Rau ib lub rooj ua haujlwm, qhov kev pub ntev ntev yog feem ntau teem ntawm 1 thiab 12 m / min. Cov khoom siv qis dua yog siv rau kev ua tiav lossis cov ntaub ntawv nyuaj, thaum cov khoom noj ntau dua yog tsim rau cov khoom sib tsoo lossis cov khoom softer.
(3) Vertical pub (qhov tob ntawm kev txiav) ntawm qhov sib tsoo lub log:
Qhov no parameter yog txiav txim raws li tus nqi ntawm tus ntoo khaub lig pub (lateral pub). Ib qho me me ntsug pub yog pom zoo thaum siv tus ntoo khaub lig pub ntau dua kom tsis txhob muaj kev sib tsoo ntau dhau thiab kev puas tsuaj thermal. Rau precision nto sib tsoo, ntsug pub feem ntau yog li ntawm 0.005 mus rau 0.05 hli ib zaug.
