Dị ka anyị niile maara, usoro ule siri ike nke ọ bụla, ma Brinell, Rockwell, Vickers ma ọ bụ ihe nleba anya Leeb hardness tester, nwere oke ya na ọ bụghị ihe niile. Maka nnukwu, dị arọ na nke na-adịghị arụ ọrụ geometric dị ka nke egosiri n'ihe atụ na-esonụ, ọtụtụ ụzọ nnwale ugbu a na-eji ihe nleba anya Leeb siri ike iji chịkwaa ike ha.
The ike nha usoro nke Leeb hardness tester nwere ọtụtụ ihe na-emetụta ike ya ziri ezi: dị ka: ihe na-agbanwe modulus, bọl isi oriri, workpiece elu roughness, curvature radius, elu obi tara mmiri oyi akwa omimi, wdg E jiri ya tụnyere static nha usoro nke Brinell, Rockwell na Vickers, njehie bụ dịtụ ukwuu ibu. Ọ bụrụ na isi ike chọrọ izi ezi ka elu, kedu ka anyị kwesịrị isi họrọ onye na-anwale ike?
Nke a na ụdị arọ workpiece na usoro nke nkịtị hardness tester ule, tupu ule loading na ebutu nke hardness tester, na ebutu nke ekweghị ekwe tester ga-eweta nnukwu ọrụ na-arụ ọrụ na usoro, otú ka anyị na-ahọrọ a hardness tester? Ndị na-esonụ na-atụ aro ka a na-eji ihe nleba anya siri ike nke nwere nhazi ebuli elu iji mezue usoro ule niile. Dị ka egosiri n'okpuru:
Nke a siri ike ule ngwọta nwere ike na-aghọta Rockwell hardness ule / Vickers na Brinell hardness ule dị ka ike ule ụkpụrụ (GB/T 231.1, GB/T 4340.1, ISO6507, ISO6508, ASTM E18, wdg), na izute elu-nkenke ule na oru oma mmepụta chọrọ nke arọ workpieces.
Ihe nleba anya na-ebuli ike nke isi na-akpaghị aka nwere oche arụrụ arụ ọrụ, nke na-ebelata mperi nke ịghasa na ibuli nke workbench na nha nha siri ike. The workbench bụ nnukwu n'ibu na ike nabata nnukwu workpieces na-atụ. Ntụle otu bọtịnụ na-ebelata nke ukwuu njehie ule na ọrụ nke onye nyocha, nke dị mma na ngwa ngwa.
