Rau ntau tus neeg muas zaub uas muaj kev xav tau siab rau qhov tseeb ntawm hardness testers, calibration ntawm hardness testers tso qhov kev xav tau ntawm hardness blocks. Niaj hnub no, kuv zoo siab los qhia cov series ntawm Class A hardness blocks.—Rockwell hardness blocks, Vickers hardness blocks, Brinell Hardness blocks, HRA, HRB, HRC, HRE HRR, HV, HBW thiab lwm yam.
Class A hardness blocks yuav tsum tau nruj me ntsis raws li cov txheej txheem ua, kev kho saum npoo, thiab cov txheej txheem kho cua sov. Kev tsim cov txheej txheem ntawm cov hardness blocks muaj cov txheej txheem machining siab heev. Lub xeev-ntawm-the-art CNC machining chaw yog ua haujlwm los xyuas kom meej tias qhov ntev ntawm cov hardness blocks ua tau raws li cov qauv nruj heev. Txhua qhov kev txiav txiav tau ua tib zoo kho kom txo tau qhov ua yuam kev me me.
Nyob rau hauv nam ntawm kev kho deg, tshwj xeeb nto xov txheej txheem yog siv. Tshuaj polishing thiab precision lapping yog nqa tawm los tsim ib tug nto nrog ib tug tsis tshua muaj roughness. Qhov no tsis yog tsuas yog txo qhov cuam tshuam ntawm qhov tsis sib xws thaum lub sij hawm ntsuas qhov nyuaj tab sis kuj tseem txhim kho qhov adhesion ntawm qhov indenter ntawm hardness tester thiab qhov chaw ntawm lub hardness block, kom ntseeg tau tias qhov ntsuas tau zoo dua.
Cov txheej txheem kev kho cua sov ntawm Class A hardness blocks kuj tseem tswj tau zoo. Kev kho cua sov siab tshaj plaws nrog cov txheej txheem tswj qhov kub thiab txias yog siv. Thaum lub sij hawm kev kho cua sov, tus nqi cua sov, tuav lub sij hawm, thiab txias npaum li cas yog tag nrho nruj tswj raws li ib tug tshwj xeeb txheej txheem nkhaus. Qhov no ua kom ntseeg tau tias cov qauv sab hauv ntawm lub hardness thaiv yog sib xws thiab ruaj khov, txo cov kev ntxhov siab hauv cov khoom siv.
Ua tsaug rau cov txheej txheem nruj no, qhov ntsuas qhov tsis meej ntawm Class A hardness blocks yog txo qis, thiab lawv cov kev sib txig sib luag yog siab dua piv rau lwm hom hardness blocks. Lawv muab lub hauv paus txhim khu kev qha ntau dua rau kev ntsuas cov hardness testers, ua kom cov hardness testers ua tiav qhov tseeb dua thiab ruaj khov hauv lawv qhov ntsuas. Txawm hais tias nyob rau hauv kev tsim khoom, kev tswj kom zoo hauv chav kuaj, lossis kev tshawb fawb txog kev tshawb fawb, Class A hardness blocks ua lub luag haujlwm tseem ceeb thiab tseem ceeb, pab cov kws tshaj lij kom tau txais cov ntaub ntawv ntsuas hardness ntau dua thiab ntseeg tau.
Los ntawm kev xaiv Class A hardness blocks, cov neeg siv khoom tuaj yeem muaj kev ntseeg siab tag nrho hauv kev ntsuas ntawm lawv cov hardness testers, kom ntseeg tau tias lawv cov hardness testers yog qhov tseeb thiab zoo ib yam, thiab yog li muab kev txhawb zog rau kev tswj xyuas zoo thiab kev tsim khoom ntawm lawv cov khoom.
