Honing raj, raws li siab - cov raj muaj qhov tseeb, yog dav siv hauv hydraulics, pneumatics, thiab precision machinery. Qhov zoo ntawm lawv cov machining ncaj qha cuam tshuam qhov kev ua tau zoo thiab kev ua neej nyob ntawm cov cuab yeej siv, ua kom paub txog cov txheej txheem honing tseem ceeb heev.
1. Kev xaiv Abrasive thiab cov cuab yeej sib xws
Qhov tseeb ntawm lub raj honing yog nyob ntawm cov khoom ntawm abrasive. Rau qhov nyuaj honing theem, silicon carbide los yog corundum abrasives nrog ib tug grit ntau ntawm 80-120 mesh yog pom zoo kom tshem tawm cov Tshuag ceev. Rau qhov zoo honing theem, pob zeb diamond abrasives nrog grit ntau ntawm 180-320 mesh yog siv los xyuas kom meej qhov roughness ntawm Ra 0.4μm los yog tsawg dua. Lub honing lub taub hau qauv yuav tsum tau kho rau lub raj txoj kab uas hla. Ib tug floating tsim feem ntau yog siv los them rau coaxiality yuam kev. Lub siab yog tswj nyob rau hauv ib thaj tsam ntawm 0.5-2MPa kom tsis txhob overload thiab puas rau lub workpiece.
2. Kev tswj kom txias thiab lubrication
Cov kub kub tsim thaum lub sij hawm honing txheej txheem yuav yooj yim ua rau workpiece deformation los yog abrasive grain dulling. Nws raug nquahu kom siv cov dej- cov kua dej soluble (xws li emulsion) lossis cov roj tshwj xeeb honing ntawm tus nqi tsis tu ncua ntawm 15-30 L / min los xyuas kom meej txaus txias ntawm qhov chaw sib tsoo thiab yaug cov chips. Rau qhov nyuaj- rau-tshuab cov ntaub ntawv xws li stainless hlau, huab cua additives yuav muab ntxiv los txhim kho lubrication.
3. Txheej txheem Parameter Optimization
Qhov sib txuam ntawm spindle ceev thiab reciprocating ceev ncaj qha cuam tshuam qhov tsim ntawm crosshatch qauv. Feem ntau, spindle ceev ntawm 80-150 rpm thiab reciprocating ceev ntawm 15-25 m / min raug pom zoo, nrog rau qhov sib piv ntawm 1: 3 thiab 1: 6 kom ua tiav lub kaum sab xis ntawm 60℃-90 degree. Tus nqi pub yuav tsum tau maj mam txo, nrog rau qhov pib honing pub ntawm 0.05-0.1 hli thiab 50% txo rau txhua qhov txuas tom ntej, thaum kawg ua kom muaj qhov ntev ntev ntawm ± 0.01 hli.
4. Kev soj ntsuam zoo thiab ua tiav
Tom qab ua tiav, cov khoom yuav tsum tau ua tiav kev tshuaj xyuas siv lub micrometer sab hauv, tus ntsuas roughness, thiab ntsuas qhov ntsuas. Yog tias kuaj pom ripples lossis tapers, lub pob zeb honing yuav tsum tau txiav tam sim ntawd los yog lub tshuab qhia kev sib npaug. Hnav cov tes tsho thiab cov ntsaws ruaj ruaj yuav tsum tau hloov tsis tu ncua los tiv thaiv cov khoom tsis xws luag los ntawm cov khoom siv teeb meem.
Kev paub txog cov tswv yim no thiab sib txuas nrog cov txheej txheem txheej txheem tuaj yeem txhim kho qhov sib xws thiab ua haujlwm ntev ntawm cov raj honing, ua tau raws li qhov xav tau ntawm kev tsim khoom siab - kawg.
