1. Cov kev cai dav dav rau daim ntawv xeem yog qhov saum npoo ntawm daim ntawv xeem yuav tsum huv, tsis muaj plua plav, roj stains, thiab oxide daim tawv nqaij.
2. Qhov yuav tsum tau ua rau qhov ntsuas kub ntawm qhov ntsuas qhov ntsuas yog qhov kub ntawm qhov ntsuas qhov ntsuas yuav tsum tsis txhob overheat thiab yuav tsum tsawg dua 120 degree. Qhov ntsuas kub zoo rau kev ntsuas yog 4 degree -38 degree .
3. Cov kev cai ntawm Leeb hardness tester rau saum npoo roughness ntawm cov qauv kuaj yuav tsum ua tau raws li qhov yuav tsum tau ua hauv cov lus hauv qab no. Qhov saum npoo roughness ntawm cov qauv kuaj tsis tsuas yog cuam tshuam rau kev kuaj qhov tseeb, tab sis kuj cuam tshuam rau lub neej kev pab cuam ntawm cov pob taub hau.
Txoj kev ua haujlwm rau kev ntsuas nkhaus workpieces siv Leeb hardness tester
(1) Cov khoom kuaj yuav tsum muab tso rau hauv av, ua kom ruaj khov thiab tsis muaj kev co. Txoj haujlwm kuaj yuav tsum tsis txhob raug ncua, thiab kev txhawb nqa yuav tsum tau ntxiv yog tias tsim nyog;
(2) Qhib lub hardness tester → Cov khoom teeb tsa ntawm cov khoom → Hardness value setting (HRC HRB HB) → Hardness testing direction setting → Start hardness test;
(3) Nias lub cuab yeej cuam tshuam kom nruj rau saum npoo kom kuaj thiab nias nws ib zaug. Tom qab 1 vib nas this, nias lub me me lub tog raj kheej protruding los ntawm hardness tester, thiab hardness tus nqi yuav cia li tso saib. Thaum lub sij hawm tus txheej txheem no, tus neeg teb xov tooj yuav tsum stabilize qhov cuam tshuam ntaus ntawv thiab tuav ib tug perpendicular kev taw qhia rau saum npoo yuav tsum tau kuaj;
(4) Txhua qhov chaw sim yuav tsum tau sim tsawg kawg yog 3 lub ntsiab lus, thiab qhov kev ncua deb ntawm ob lub ntsiab lus ntsuas yuav tsum siab dua lossis sib npaug li 3 hli. Tom qab kev sim, qhov nruab nrab tus nqi yuav tsum tau muab coj los ua qhov hardness ntawm cheeb tsam, thiab kaw ua ntej mus rau qhov chaw sim tom ntej;
(5) Sib piv cov txiaj ntsig ntawm Leeb hardness tester nrog cov kev cai ntawm cov khoom, thiab yog tias lawv ua tau raws li qhov yuav tsum tau ua, lawv raug suav tias tsim nyog, thiab mus rau cov txheej txheem tom ntej; Yog tias tsis tsim nyog, hloov mus rau thaj chaw cais tawm thiab sau cov ntawv xeem
