Lero ndikufuna ndikudziwitseni choyesa cholimba cha Rockwell chokhala ndi mphamvu yaying'ono yoyesera kuposa Rockwell hardness tester:

Superficial Rockwell hardness tester ndi mtundu wa Rockwell hardness tester.Imagwiritsa ntchito mphamvu yocheperako.Mukayesa zida zazing'ono komanso zoonda, kugwiritsa ntchito Rockwell hardness tester kumabweretsa miyeso yolakwika.Titha kugwiritsa ntchito Superficial Rockwell hardness tester.Hardness tester itha kugwiritsidwanso ntchito kuyeza zogwirira ntchito ndi zigawo Zapamwamba zolimba.
Mfundo yake yoyesera ndiyofanana ndendende ndi ya Rockwell hardness tester.Kusiyana kwake ndikuti kuyesa koyambirira ndi 3KG, pomwe kuyesa koyamba kwa Rockwell hardness tester ndi 10KG.

Superficial Rockwell hardness tester tester level: 15KG, 30KG, 45KG

Indenter yomwe imagwiritsidwa ntchito mu Superficial Rockwell hardness tester imagwirizana ndi Rockwell hardness tester.:

1.120degree diamondi cone indenter

2. 1.5875 zitsulo mpira indenter

Mwapamwamba RockwellMulingo wa hardness tester:

HR15N, HR30N, HR45N, HR15T, HR30T, HR45T

(Sikero ya N imayesedwa ndi indenter ya diamondi, ndipo sikelo ya T imayesedwa ndi indenter ya mpira wachitsulo)

Kuuma kumawonetsedwamonga: kuuma mtengo kuphatikiza sikelo ya Rockwell, mwachitsanzo: 70HR150T

15T imatanthawuza cholozera mpira wachitsulo chokhala ndi mphamvu yoyesera ya 147.1N (15 kgf) ndi indenter ya 1.5875

Kutengera pamwamba chaRacteristics, Superficial Rockwell ali ndi zotsatirazi:

1. Popeza ili ndi ziwirimitu yamphamvu, ndiyoyenera pazida zonse zofewa komanso zolimba zachitsulo.

2. Mphamvu yoyesera ndi smzonse kuposa za Rockwell kuuma tester, ndi Kuwonongeka Kwambiri kwa workpiece ndi kochepa kwambiri.

3. Mphamvu yaying'ono yoyeserae akhoza m'malo mwa Vickers hardness tester, yomwe ndi yotsika mtengo komanso yotsika mtengo.

4. Njira yoyesera ndi yofulumira ndipo workpiece yomalizidwa imatha kudziwika bwino.
