Usoro nrụpụta nke Tungsten Carbide Grinding Quills: Site na ntụ ntụ ruo ngwa ngwa.

Tungsten carbide egweri quills bụ ngwá ọrụ dị oke mkpa n'ọhịa nke ịdị elu dị elu, na arụmọrụ ha pụrụ iche sitere na usoro nrụpụta mara mma. Njem site na ntụ ntụ-larịị micron gaa na ngwá ọrụ ziri ezi gụnyere usoro nke usoro a na-achịkwa nke ọma.

Ngwakọta ihe eji eme ihe na ngwakọta

Nrụpụta na-amalite site na ahọpụtara nke ọma tungsten carbide ntụ ntụ na ntụ ntụ cobalt. Cobalt na-arụ ọrụ dị ka akụkụ nke njikọ, ọdịnaya ya na-emetụta isi ike na isi ike nke ngwaahịa ikpeazụ. Na-emekarị, ọdịnaya cobalt sitere na 6% ruo 12%, nke a haziri ahazi dịka ngwa chọrọ. A na-agwakọta ntụ ntụ dị larịị micron ndị a n'ime igwe igwe bọọlụ iji hụ na nkesa otu ọkwa molekul.

Usoro nhazi

A na-efesa slurry agwakọtara n'ime granules na-asọ asọ. Mgbe nke ahụ gasịrị, a na-eji teknụzụ oyi isostatic pressing nkenke na-arụ ọrụ iji kpoo ihe ahụ na nrụgide 200-300 MPa. N'oge a, a na-emepụta ọdịdị geometric bụ isi nke eriri carbide na-egweri, ma ike ka dị ala, na-achọ nhazi ọzọ.

Usoro mmechi

Sintering bụ isi usoro nke mmepụta ihe. N'ime ọkụ na-ekpo ọkụ na-ekpo ọkụ, a na-achịkwa okpomọkụ nke ọma n'elu ebe mgbaze nke cobalt (na-emekarị 1400-1500 ° C). N'ime oge a, akụkụ cobalt na-agbaze ma na-eme ka akụkụ nke tungsten carbide dị nro, na-eme njikọ siri ike nke metallurgical site na ntinye mmiri mmiri. Njikwa ziri ezi nke usoro ikpo ọkụ na ijide oge dị mkpa iji hụ na njupụta zuru oke na uto ọka na-achịkwa.

Nrụpụta nkenke

Ogwe ihe egweri carbide na-enweghị oghere na-abanye n'ọkwa nhazi nke ọma, nke dị oke mkpa maka ịhụ na ihe egweri ahụ na-emezu ihe achọrọ. A na-ebu ụzọ rụọ igwe benchmark site na iji igwe igwe cylindrical ultra-nkenke nwere wiil igwe na-egweri diamond iji guzobe axis ntụaka ziri ezi, yana nnabata akụkụ na-achịkwa n'ime ± 0.01 mm.

Usoro nhazi nkenke nkenke gụnyere:

1. Ngwá ọrụ shank nhazi: Iji elu nkenke grinders na diamond wheel, gụnyere ike ichikota, ọkara-emecha, na finishing. Iri ihe siri ike na-ewepụ ihe gabiga ókè, ọkara imecha na-enweta ihe achọrọ n'ụdị, yana imecha na-eme ka ọ dị oke ala Ra ≤ 0.2 μm. Nkwenye nkuku taper maka HSK, CAPTO, na ihu ndị ọzọ ga-abụrịrị n'ime ± 30".

2. Nhazi oghere dị jụụ: Iji akụrụngwa na-egwupụta oghere dị omimi na teknụzụ ịkụ egbe egbe. Iji hụ na ịdị mma nke mgbidi oghere, a ga-achịkwarịrị ngwa ngwa nri (nke bụ 50-100 mm / min) na nrụgide coolant (10-15 MPa). Izi ezi dayameta oghere ga-erurịrị ọkwa H7, yana njehie kwụ ọtọ agaghị agafe 0.02/100 mm.

3. Dynamic itule: Iji pụrụ iche itule igwe iji dozie uka nkesa site symmetrically wepụ ihe. Ihe ndị a chọrọ gụnyere ị nweta ọkwa nguzozi G2.5 yana enweghị nguzozi na-erughị 1 g·mm/kg na oke ọsọ ọrụ.

Nyocha ogo

Nyocha ikpeazụ gụnyere ịhazi igwe nlegharị anya maka akụkụ geometric, interferometer laser maka ụdị na nnabata ọnọdụ, igwe na-edozi maka nnwale nguzozi ike, yana microscopes metallurgical maka nyocha nhazi ihe. Naanị ngwaahịa gafere ule niile siri ike ka enwere ike ibunye.

Usoro nrụpụta dum na-ejikọta ọtụtụ teknụzụ gụnyere ntụ ntụ ntụ, nhazi nkenke, na ọgwụgwọ okpomọkụ. Njikwa ziri ezi na ọkwa ọ bụla na-enye aka n'otu n'otu na arụmọrụ pụrụ iche nke tungsten carbide egweri quills. Karịsịa n'ime usoro nhazi nkenke, ngwa zuru oke nke teknụzụ ngwa ngwa siri ike, teknụzụ nha nkenke, yana teknụzụ njikwa akpaaka na-eme ka n'ichepụta ọkwa micron.
