I-rockwell iqhina kunye neViskers Iindlela zokuvavanya ubunzima kwi-aluminium nitride i-ceramidi kunye neendlela zokuvavanya ukuqengqa kwentsimbi

I-1.Rockwell Knoop ye-Viskers Dights Recence Fed ye-Aluminium Nitride ceramics
Kuba izixhobo ze-ceramic zinesakhiwo esinzima, zinzima kwaye zibuhlungu zendalo, kwaye zinesiphene seplastiki yeendlela ezisetyenziswayo ziquka ii-vysseds, i-nop deced kunye nobunzima. Inkampani yeShanccai ineentlobo ezahlukeneyo zobunzima, kuvavanyo olwahlukileyo kunye neemvavanyo ezahlukeneyo ezinobunzima.
Le migangatho ilandelayo inokusetyenziswa njengesalathiso:
I-GB / T 230.2 Izixhobo zeMeticic Izixhobo zovavanyo lwe-robwell
Zininzi izikali ze-roubwell, kunye ne-ceramic isebenzisa i-HRA okanye i-HRC Scales.
I-GB / T 4340.1-19999 i-visters yensimbi yensimbi kunye ne-GB / T 18449.1001 yeenyikima zentsimbi.
I-Knoop kunye ne-Vic-Vic-Vic-Vistas
Kufanelekile ukuba uqaphele ukuba ngenxa yobume obukhethekileyo bemveliso, sinokususa i-indents engasebenziyo ngokwemeko ye-induction ngexesha lokulinganisa ukufumana idatha echanekileyo yokufumana idatha echanekileyo.
2.Ukunikezela ngeendlela zokuqengqeleka zensimbi
Ngokweendlela zokuvavanya ubunzima beendlela zensimbi kunye nezingafanelekanga zensimbi ezichazwe kwi-JB / T7361-2007, zininzi iindlela zovavanyo ngokwemigangatho ye-Shanacai:
I-1) Indlela yokuvavanya ubunzima
Ngokubanzi, iinxalenye ezikhuselweyo zivavanywa ngendlela yovavanyo lwe-Vivers. Ingqwalaselo kufuneka ihlawulwe kumphezulu wokugqiba komsebenzi kunye nokukhethwa kwamandla ovavanyo.
I-2) Indlela yovavanyo lwe-rockwell
Uninzi lweemvavanyo ezinzima ze-robwell ziqhutywa kusetyenziswa isilinganiselo se-HRC. I-Shanccai Rockwell Hester titer iqokelele iminyaka eli-15 yamava kwaye inokuhlangabezana nazo zonke iimfuno.
3) Indlela yovavanyo lwe-leeb
Uvavanyo lwe-leeb ubunzima bunokusetyenziselwa iibherangi ezifakwe okanye ezinzima ukuba zichitheki. Ukuchaneka kwayo kulungelelwaniso akulunganga njengaleyo ye-Bestatop Hester.
Lo mgangatho usetyenziswa kakhulu kuvavanyo lobunzima benxalenye yokuthwala intsimbi, iinxalenye ezinamathele kwaye zinomvuzo obandakanyekileyo kwaye zigqibelele iinxalenye ze-Bertines zentsimbi.
