SEVENTEEN FACTORS AFFECTING GRINDING ACCURACY ntawm GRINDING Log

1.Wheel hardness: Lub hardness ntawm lub sib tsoo log cuam tshuam rau kev sib tsoo quab yuam thiab qhov chaw sib cuag ntawm lub log thiab lub workpiece. Lub log nyuaj tuaj yeem tswj nws cov duab zoo dua, thaum lub log softer tuaj yeem hnav sai dua, cuam tshuam rau kev sib tsoo qhov tseeb.

2.Wheel qib: Qib ntawm kev sib tsoo log txiav txim siab nws lub zog thiab muaj peev xwm tiv taus deformation thaum sib tsoo. Lub log qib siab dua muab kev ruaj ntseg zoo dua thiab raug.

3.Wheel qauv: Cov qauv ntawm kev sib tsoo log yog hais txog kev npaj ntawm cov nplej abrasive thiab cov khoom siv nyiaj. Lub denser qauv muab qhov tseeb zoo dua, thaum lub coarser qauv tso cai rau kev tshem tawm cov khoom sai.

4.Wheel grain loj: Qhov luaj li cas ntawm cov nplej abrasive ntawm lub log sib tsoo cuam tshuam rau qhov chaw tiav thiab kev sib tsoo raug. Cov nplej me me muab qhov ua tiav zoo dua thiab raug zoo dua.

5.Wheel daim ntawv cog lus: Cov khoom siv sib txuas ntawm cov nplej abrasive hauv kev sib tsoo lub log cuam tshuam lub log kev ua haujlwm. 6.Different daim ntawv cog lus muaj qhov sib txawv ntawm qhov muaj zog thiab hnav tsis kam, uas tuaj yeem cuam tshuam kev sib tsoo raug.

7.Wheel ceev: Kev sib hloov ceev ntawm kev sib tsoo lub log cuam tshuam rau kev txiav thiab qhov tseeb. Kev nrawm dua tuaj yeem ua rau muaj cua sov ntau ntxiv thiab txo qhov raug, thaum qis qis yuav ua rau cov khoom tshem tawm qeeb dua.

8.Workpiece ceev: Qhov ceev ntawm lub workpiece txav mus rau qhov sib tsoo log cuam tshuam rau kev sib tsoo quab yuam thiab raug. Kev xaiv kom zoo ntawm workpiece ceev kom tshem tawm cov khoom zoo yam tsis muaj kev cuam tshuam qhov tseeb.

9.Qhov tob ntawm kev txiav: Qhov tob ntawm kev txiav, los yog cov khoom siv tshem tawm ib qho dhau, cuam tshuam rau kev sib tsoo quab yuam thiab raug. Qhov tob tob ntawm kev txiav muab qhov tseeb zoo dua, thaum txiav tob dua tuaj yeem ua rau lub log deflection thiab txo qhov raug.

10.Coolant hom thiab ntws tus nqi: Kev siv cov coolant pab dissipate tshav kub generated thaum sib tsoo, txo thermal distortion thiab txhim kho raug. Xaiv cov hom coolant tsim nyog thiab tswj cov nqi txaus yog qhov tseem ceeb rau kev sib tsoo kom raug.

11.Machine rigidity: Lub rigidity ntawm lub tshuab sib tsoo cuam tshuam rau tag nrho kev ruaj ntseg thiab qhov tseeb ntawm cov txheej txheem sib tsoo. Lub tshuab nruj txo qis kev vibrations thiab deflections, kom ntseeg tau tias kev sib tsoo zoo ib yam.

12.Machine alignment: Kev sib raug zoo ntawm cov khoom sib tsoo tshuab, xws li cov spindle, rooj, thiab cov kev taw qhia, yog qhov tseem ceeb heev rau kev ua tiav kev sib tsoo siab. Misalignment tuaj yeem ua rau muaj kev sib tsoo tsis sib xws thiab txo qhov raug.

13.Kev hnav khaub ncaws thiab qhov tseeb: Kev hnav khaub ncaws tsis tu ncua thiab qhov tseeb ntawm kev sib tsoo lub log pab tswj nws cov geometry thiab sharpness, kom ntseeg tau tias kev sib tsoo qhov tseeb thoob plaws hauv cov txheej txheem.

14.Workpiece clamping: Kev clamping ntawm lub workpiece kom ruaj khov thiab txo qhov kev pheej hmoo ntawm kev txav mus los thaum sib tsoo, pab txhim kho qhov tseeb.

15.Grinding ib puag ncig: Environmental yam, xws li kub, av noo, thiab huab cua zoo, tuaj yeem cuam tshuam cov txheej txheem sib tsoo thiab raug. Kev tuav tswj ib puag ncig yuav pab txo cov teebmeem no.

16.Operator txuj ci: Cov kev txawj ntse thiab kev paub ntawm tus neeg teb xov tooj ua lub luag haujlwm tseem ceeb hauv kev ua tiav kev sib tsoo siab. Kev cob qhia kom raug thiab nkag siab txog cov txheej txheem sib tsoo yog qhov tseem ceeb rau kev pom zoo.

17.Material properties: Lub cev thiab tshuaj lom neeg ntawm cov khoom siv ua haujlwm cuam tshuam rau kev sib tsoo thiab raug. Nkag siab txog cov yam ntxwv ntawm cov khoom siv thiab xaiv cov kev sib tsoo uas tsim nyog yog qhov tseem ceeb rau kev sib tsoo kom raug.

Cov cuab yeej siv: Kev hnav ntawm lub log sib tsoo cuam tshuam rau nws qhov kev ua tau zoo thiab raug raws sijhawm. Kev soj ntsuam cov cuab yeej hnav thiab hloov cov log hnav sai sai pab tswj kev sib tsoo kom raug.

Txawm hais tias cov lus hais saum toj no tau hais txog cov ntsiab lus tseem ceeb uas cuam tshuam rau kev sib tsoo qhov tseeb ntawm lub log sib tsoo, qhov xwm txheej tiag tiag yuav txawv nyob ntawm cov txheej txheem tshwj xeeb thiab cov yam ntxwv ntawm cov khoom ua haujlwm. Yog li ntawd, hauv kev siv tswv yim, ntau yam yuav tsum tau ua kom tiav, thiab kho thiab kho kom zoo raws li qhov xwm txheej tshwj xeeb kom ntseeg tau tias qhov kev sib tsoo yuav tsum tau ua tiav.
