Qhov tseeb yog tias kev sib tsoo ntawm kev kub ceev nce qhov kub ntawm cov khoom hauv av, thiab qhov no yog fraught nrog uncontrollabable ntawm tus txheej txheem ntawm spontaneous tso tawm ntawm hardened hniav hniav. Qhov tshwm sim yog kwv yees. Cov riam tom qab ntawd yuav muab pov tseg.
Nws hloov tawm tias qhov ntsuas tau zoo ntawm cov cuab yeej siv tes ntse tuaj yeem dhau ntawm cov cuab yeej coj mus rau qib tsim nyog los ntawm lub Hoobkas automation.
Ib qho bar rau sharpening ib rab riam yuav tsum muaj ob feem:
- abrasive nplej ntawm cov khoom siv tawv dua li cov khoom siv los ua;
- matrix ntawm cov khoom yas uas muaj peev xwm tuav tau thawj lub hauv paus ntawm tib lub bar zoo li.
Feem ntau, qhov nyuaj ntawm cov qauv yog piv rau cov khoom siv hauv av,qee zaum tsawg.
Nws yog qhov tsim nyog los xaiv cov yam ntxwv ntawm matrix kom raug, qhov no yuav tso cai rau nws hnav thaum lub sijhawm ua haujlwm thiab nthuav tawm cov nplej tshiab. Cov laus, dulling, crumble. Cias muab, thaum cov khoom tiav yog erased, lub bar rau sharpening riam kuj erased. Nov yog nws txoj haujlwm ib txwm muaj. Yog hais tias lub template yog mos heev, lub bar yuav sharpen tsis zoo. Nyob rau hauv cov ntaub ntawv no, abrasive nplej yuav raug rub tawm ntawm lub mos matrix los ntawm cov txheej txheem txheej txheem. Self-absorbing, lub bar yuav sai sai poob qhov tsim nyog cov duab ntawm kev sib cuag nto nrog cov khoom ua tiav. Kev ua haujlwm yuav tsis raug.
Tus yam ntxwv tseem ceeb ntawm abrasive yog qhov sib xws ntawm nws qhov ntau thiab tsawg. Yog hais tias qhov ntev ntawm cov nplej sib txawv, ces lub sharpening yuav tsis yog heev, thiab cov tshwm sim yuav random. Tau kawg, rab riam ntse ntse yuav tsum yog cov khoom zoo, tab sis cia peb ua ib qho tam sim ntawd: kev ua haujlwm zoo ncaj qha nyob ntawm tus tswv kev txawj ntse, thiab tsuas yog tom qab ntawd ntawm qhov zoo ntawm cov khoom.
Tus huab tais ntawm cov ntaub ntawv abrasive yog pob zeb diamond. Nyob rau hauv nws siv lead ua lattice, cov nplej muaj ib tug ntse zoo. Lawv tsis hloov nws thaum lub sijhawm ua haujlwm. Hais kom yooj yim, txhob ruam.
Pob zeb diamond riam ntse yuav tsis poob nws cov duab tiaj tus. Cov txheej zoo li no muaj qhov tuab ntsuas hauv millimeters, yog li txhua tus tham txog kev txhim kho ntawm cov khoom siv no yog qhov tsis muaj tseeb. Ua ntej ua hauj lwm nrog xws li ib tug bar, nws yuav tsum tau moistened nrog dej, ces nws yuav abrade hlau nto.sai dua thiab kub tsawg.
Tab sis feem ntau "khiav" yog thiab tseem nyob hauv ceramic whetstones rau sharpening riam. Qhov txiaj ntsig tsis txaus ntseeg ntawm cov cuab yeej zoo li no yog lawv qhov hnav tsis kam thiab cov peev txheej loj. Lub matrix ntawm xws li tuav hnav tawm maj mam. Tab sis kuj muaj lwm sab ntawm lub npib. Thaum lub sijhawm ua haujlwm, cov khoom siv ceramic tau nrawm nrawm nrog cov khoom me me ntawm abraded steel, thiab qhov no ua rau poob ntawm cov khoom abrasive. Txhawm rau rov ua haujlwm ntawm cov cuab yeej zoo li no, cov tshuaj ntxuav tais diav hauv chav ua noj zoo tib yam yuav pab tau.
Thiab thaum kawg, cov lus qhia me ntsis rau cov pib tshiab. Koj tsis tas yuav khoom kim heev tam sim ntawd. Txawm tias qhov zoo tshaj plaws abrasive yuav yog ib qho bar yog tias koj tsis muaj kev txawj ua haujlwm nrog nws.
