Amakhiwe angenalutho - inkinga yangempela kuyo yonke inkosikazi kanye nesizathu esengeziwe sokuxabana nomyeni wakhe. Ukuze inqubo yokusika ukudla kuqhubeke kalula, futhi endlini ibe nomkhathi ohlelekile, itshe lokugaya kumele libe yindawo yokubophezela ekhishini.
Indlela yokukhetha i-grindstone?
Ngokunakekelwa kokuthengwa kwezinto ezidingekayo zokukhulisa imimese, ngokuqinisekile uzothola inkinga yokukhetha. Kungabonakala, yini engaba lula kunokuthola ibha nge-surface abrasive? Kodwa namuhla imakethe inikeza izinhlobo eziningi zayo, ngakho amehlo agijima, futhi izandla ziyahla. Uma ulahlekelwa, lokhu kubuyekezwa kuzokusiza ukunquma.
Izinhlobo zokugaya amatshe
1. I-grindstone yemvelo , eyenziwe ngesimo se-bar ye-emangqamu noma isimo se-oval. Ziyingxenye yento yemvelo, isibonelo, i-crystalline silica noma i-quartz. Ngokwehlobo lokusebenzisana ne-blade, itshe lokugaya lemvelo libhekisela emanzini - ngaphambi kokuqala inqubo yokugaya, kufanele ifakwe emanzini imizuzu engaba ngu-10. Ukuhlanganiswa kwabo okungenalutho kungukuthi umphumela utholakala ngokushesha futhi kalula ngangokunokwenzeka. Kodwa kukhona ukuphazamiseka. Ngakho-ke, ukuphila komsebenzi we-grindstone onjalo akuyisikhathi eside, ngoba ubuso obumnyama bukhishwa ngokushesha, futhi itshe ngokwayo lithola ukungalingani. Kodwa lokhu, akusiyona inkinga enkulu, ngoba uma ifunwa, itshe lingadalwa.
Indlela yokulinganisa i-grindstone?
- gubha itshe elimanzi phezu kwesitini se-silicate;
- Sebenzisa i-grindstone nge-granularity ekhudlwana, futhi ingancibilikiswa ngamanzi;
- kwi-slab ekhonktshi noma ekhoneni.
Eminye ubunzima ekusebenziseni ama-grindstones wamanzi, kubalulekile ukuwageza ngokuphelele kusuka kuyizinhlayiya zothuli oluthile ngemva kokusetshenziswa ngalunye.
2. Amatshe okugcizelela okufakelwayo - into ehlukumezayo ihlanganiswe nemigqa ekhethekile ye-viscosity, okuvela kuwo okudingeka ukuthi usebenzise amafutha uma ugaya. Kudingekile ukuqinisekisa ukuthi itshe le nqubo yokusebenza ayihlanganiswa ne-gloss yezinhlayiya zensimbi ngakho-ke, ayilahlekelwa yizindawo zayo. Kumele uqaphele ukuthi imifino evamile yemifino noma yemishini ayifanele lapha, udinga ukusebenzisa imithi ekhethekile edayiswa kwisethi enegayidi.
Imigoqo yokufakelwa yenziwa ngokuyinhloko kusuka kumabhola e-electrocorundum ne-glue, njenge-binder. I-degree ye-granularity incike kwikhwalithi yezinto ezikhona, kanye nekhwalithi ye-bar. Ngokuhlukile kuyadingeka ukuba unikeze ukugcizelela amatshe nge-diamond uthuli. Njengoba wazi, idayimane - indaba ehlala isikhathi eside kakhulu, ngakho-ke le bar izoba yindawo ehlala phambili kakhulu. Kufanelekile ukunaka ubukhulu be-diamond e-crumb - encane, ingcosana ummese okhanyelayo, ofezekile ngosizo letshe elinjalo.
3. I- grindstone yokugaya - isimanje kunazo zonke ezingenhla. Hlanganisa ikhwalithi yokucubungula amatshe enziwe ngamatshe futhi ukugqoka ukumelana ne-diamond bars. Ukuphazamiseka ukuthi inqubo yokukhalipha imivese ngosizo lwabo ithatha isikhathi eside.
Indlela yokulola ummese ngetshe lokugaya?
- Ukulungiselela ibha yokugaya - ukugcoba ngamafutha noma kumanzi ngamanzi kuye ngokuthi uhlobo.
- Hlola i-angle ye-blade ngenkathi uhlaziya. Iningi labachwepheshe bayavuma ukuthi kungu-20⁰.
- Yenza ngokujulile ukunyakaza okuhambayo ngokushelela okwehla kwekhasi eduze nensimbi yokugaya.
Izincomo ezengeziwe, uma zikhona, zivame ukuboniswa emiyalweni yemimese. Kodwa kunoma yikuphi, kufanele kukhunjulwe ukuthi ukufunda ukulungisa ithuluzi lekhishi kuyindaba yesikhathi nesipiliyoni.
