Kedu ihe njirimara nke ngwaọrụ ịkpụ carbide?
Ngwa ọrụ carbide, ọkachasị ngwa ọrụ carbide nwere ike ịkọwapụta, bụ ngwaahịa na-ebute ụzọ nke ngwaọrụ igwe CNC. Kemgbe 1980s, ụdị ngwaọrụ carbide siri ike na nke nwere ike ịkọwapụta, ma ọ bụ ntinye, agbasawanyela na mpaghara nhazi dị iche iche. Ngwa, jiri ngwaọrụ carbide nwere ike ịdebanye aha gbasaa site na ngwaọrụ dị mfe yana ndị na-eji igwe igwe ihu ruo na nkenke, mgbagwoju anya na ngwaọrụ akpụ. Yabụ, kedu ihe njirimara nke ngwaọrụ carbide?
1. Elu siri ike: Cemented carbide ịbe ihe bụ carbide nwere nnukwu ike ike na ebe mgbaze (nke a na-akpọ hard phase) na ihe nkedo metal (nke a na-akpọ bonding phase) site na usoro nchara ntụ ntụ, na ike ya bụ 89~93HRA, dị elu karịa nke nke ígwè dị elu, na 5400C, ike ahụ ka nwere ike iru 82-87HRA, nke bụ otu ihe ahụ dị elu na okpomọkụ nke ụlọ (83-86HRA). Isi ike nke carbide cimented dịgasị iche na ọdịdị, ọnụọgụgụ, nha ọka na ọdịnaya nke oge njide ígwè, na n'ozuzu na-ebelata site na mmụba nke ihe na-ejikọta ígwè. Site na otu ọdịnaya nke nrapado, ike nke YT alloy dị elu karịa nke YG alloy, ebe alloy nwere TaC (NbC) nwere ike siri ike na oke okpomọkụ.
2. Na-ehulata ike na ike: The ekwe ike nke nkịtị cemented carbide dị na nso nke 900-1500MPa. Ọdịnaya dị elu nke usoro njikọ ígwè, ka ike na-ehulata dị elu. Mgbe ọdịnaya njide bụ otu, YG(WC-Co). Ike nke alloy dị elu karịa nke alloy YT (WC-Tic-Co), ike na-ebelata site na mmụba nke ọdịnaya TiC. Carbide cimented bụ ihe na-emebi emebi, na mmetụta ike ya na ụlọ okpomọkụ bụ naanị 1/30 ruo 1/8 nke HSS.
3. Ezigbo mgbochi iyi. The ọnwụ ọnwụ nke cemented carbide ngwaọrụ bụ 4 ~ 7 ugboro elu karịa nke elu-ọsọ ígwè, na ngwá ọrụ ndụ bụ 5 ~ 80 ugboro elu. Maka imepụta ihe na-emepụta ihe na ihe atụ, ndụ ọrụ dị 20 ruo 150 ugboro karịa nke ígwè ígwè ígwè. Ọ nwere ike ibelata ihe siri ike nke ihe dịka 50HRC.
Ojiji nke carbide ngwaọrụ: carbide ngwá ọrụ na-ejikarị na CNC machining center, CNC ihe osise igwe. Enwere ike itinye ya n'igwe igwe igwe nkịtị iji hazie ụfọdụ ihe siri ike na-enweghị mgbagwoju anya na-ekpo ọkụ.
Ka ọ dị ugbu a, ngwá ọrụ nhazi nke ihe ndị mejupụtara, plastik ụlọ ọrụ mmepụta ihe, ihe plexiglass na ihe ndị na-emepụta ihe na-emepụta ihe na-emepụta ihe ndị dị na ahịa bụ ngwá ọrụ carbide niile, nke nwere njirimara nke ike siri ike, na-eyi nkwụsi ike, ịdị mma dị mma, nkwụsị ọkụ na nkwụsị nke corrosion. Ya na usoro nke magburu onwe ya, karịsịa ya elu ike ike na-eyi nguzogide, ọ bụrụgodị na ọ na-anọgide na-agbanwe agbanwe na okpomọkụ nke 500 Celsius C, ọ ka nwere nnukwu ike na 1000 Celsius.
