Kev txiav txim siab yog tias lub tshuab dabtsi yog khoov xav tau kev kho dua tshiab feem ntau yog nyob ntawm qhov kev ntsuam xyuas dav dav ntawm cov khoom xws li kev poob qis hauv cov cuab yeej siv, hnav cov kev txwv ntawm cov khoom tseem ceeb, thiab kev poob siab heev. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:
Core Judgement Indicators
Kev pheej hmoo siab dhau Machining Accuracy kam rau ua: Txawm tias tom qab ntsuas tus ntsuas grating thiab kho cov nyiaj deflection, qhov khoov lub kaum ntse ntse tseem tshaj ± 0.5 degree, ua rau cov khoom tsis zoo ntawm qhov sib xws. Qhov no qhia tau hais tias cov khoom siv siv tshuab (xws li slider thiab worktable) tau dhau los ua qhov tsis zoo los yog hnav.
Feem ntau Hydraulic System Failures:
Lub slider nthuav tawm cov zawv zawg tsis tu ncua (lub zog to), uas tsis tuaj yeem daws tau txawm tias tom qab hloov cov ntsaws ruaj ruaj;
The hydraulic oil temperature rises abnormally (>70 degree), thaum lub tshuab cua txias ua haujlwm ib txwm;
Rov ua kev puas tsuaj rau cov khoom tseem ceeb xws li lub pob nyem valve thiab proportional valve qhia tau hais tias sab hauv cov kab mob sib kis los yog cov qauv kev laus.
Hnyav Mechanical Structure Hnav
Obvious scratches, pitting, or decreased hardness appear on the guide rail surface; Ball screw preload cannot be adjusted, and backlash is excessive (>0.05mm); Parallelism sib txawv ntawm cov slider thiab lub rooj ua haujlwm tshaj 0.1mm thiab tsis tuaj yeem kho los ntawm servo them nyiaj.
Tsis ruaj tsis khov hluav taws xob tswj System
Feem ntau CNC system sib tsoo thiab lub tswb tshwm sim, thiab qhov txawv txav tshwm sim txawm tias tom qab kev pabcuam thaub qab; Servo motor encoder signals drift, thiab hloov roj teeb tsis zoo; Kev sib txuas lus cuam tshuam tshwm sim nrog ntau lub I / O modules, thiab kev laus txoj hlua yog qhov nyuaj rau kho.
