Lub Universal hardness tester yog qhov tseeb cov cuab yeej ntsuas raws li ISO thiab ASTM cov qauv, tso cai rau cov neeg siv ua Rockwell, Vickers thiab Brinell hardness tests ntawm tib lub twj paj nruag.Lub universal hardness tester yog kuaj raws li Rockwell, Brinell, thiab Vickers cov hauv paus ntsiab lus es tsis yog siv cov kev sib raug zoo ntawm cov hardness system kom muab tau ntau yam hardness qhov tseem ceeb.
Peb hardness scales haum rau ntsuas workpieces
HB Brinell hardness scale yog haum rau ntsuas qhov hardness ntawm cam khwb cia hlau, non-ferrous alloys, thiab ntau yam annealed thiab tempered steels.Nws tsis tsim nyog rau kev ntsuas cov qauv lossis cov khoom ua haujlwm uas nyuaj dhau, me me dhau, nyias dhau, thiab tsis txhob tso cov indentations loj rau ntawm qhov chaw.
HR Rockwell hardness scale yog haum rau: hardness ntsuas ntawm kev kuaj pwm, quenching, quenching thiab tempering tshav kub-kho qhov chaw.
HV Vickers hardness scale yog tsim los ntsuas qhov hardness ntawm cov qauv thiab qhov chaw nrog rau qhov chaw me me thiab siab hardness qhov tseem ceeb, hardness ntawm infiltrated txheej los yog coatings tom qab ntau yam kev kho deg, thiab hardness ntawm nyias cov ntaub ntawv.
Tshiab ntau yam ntawm universal hardness testers
Sib txawv ntawm cov tsoos universal hardness tester: lub cim tshiab universal hardness tester siv quab yuam sensor technology thiab kaw-voj quab yuam tawm tswv yim system los hloov lub luj-loading tswj qauv, ua qhov kev ntsuas yooj yim thiab ntsuas tus nqi ruaj khov.
Optional degree ntawm automation: tshuab taub hau tsis siv neeg nqa hom, kov npo digital zaub hom, khoos phis tawj ntsuas hom
Xaiv qhov kev xeem quab yuam, hardness zaub hom thiab hardness daws teeb meem

Hardness tus nqi zaub hom: Kov npo zaub rau Rockwell, kov npo zaub / computer zaub rau Brinell thiab Vickers.
Hardness daws teeb meem: 0.1HR (Rockwell);0.1HB (Brinnell);0.1 HV (Vickers)
