Insimbi engagqwali inezindawo eziningi ezenza ithandeke ezinhlotsheni zezinhlelo zokusebenza, kodwa lezi zakhiwo ezifanayo zingenza kube nzima ukusebenza nazo. Ngesikhathi sokusetshenziswa, kuklwejwa kalula futhi kungcoliswe, okwenza kube lula ukugqwala. Okokugcina, kubiza kakhulu kune-carbon steel, ngakho-ke indaba yezindleko zempahla iyanda lapho kukhiqizwa izingxenye zensimbi engagqwali.
Amakhasimende nawo alindele lukhulu ngekhwalithi yokuphothula, afune isiphetho esicishe sifane nesibuko sempahla ezokwethulwa njengomkhiqizo oqediwe ngokwemvelo yawo. Mancane kakhulu amathuba okufihla iphutha ngokugcotshwa noma ngopende.
Lapho usebenza ngamapayipi ensimbi engagqwali, lezi zinkinga zanda ngezinga elithile, njengoba ukukhethwa kwamathuluzi alungile futhi asebenzayo okucubungula izinto ezilula ekuqedeni kunqunyelwe.
Ngenxa yokumelana nokugqwala, insimbi engagqwali ilungele ukusetshenziswa okudinga ukukhanya kwemvelo kwensimbi, njengamasondo esiteringi nezindawo zokubeka izingalo. Lokhu kusho futhi ukuthi ububanzi bangaphandle beshubhu bungahluka ukusuka kuqhwa ukuya ekubukekeni okubushelelezi, okungenasici.
Lokhu kudinga ithuluzi elilungile elihlanganiswe ne-abrasive elungile. Ngokuvamile umbuzo wokuqala esiwubuza amakhasimende ethu ukuthi iyiphi i-investimenti azimisele ukuyenza ukuze aqinisekise ukuthi athola ipayipi elifunekayo liphela ngokushesha nangokungaguquguquki. Kulabo abafuna ukugcina ukugeleza okuqhubekayo kwama-oda wokuqeda amapayipi, ukwenza ngokuzenzakalela inqubo nge-grinder engenaziko, i-cylindrical grinder, noma olunye uhlobo lomshini webhande ngokuqinisekile kungenza kube lula ukuhlunga izingxenye ukuze kuzuzwe umphumela oyifunayo. Ukuzinza komkhiqizo oqediwe nakho kungafinyelelwa kusuka engxenyeni kuya engxenyeni.
Nokho, kukhona futhi izinketho zamathuluzi ezandla. Kuye ngobukhulu bepayipi, i-grinder yebhande ingaba yindlela ephumelelayo yokuqinisekisa ukuthi ingxenye yejometri ayishintshi ngesikhathi sokuqeda. Ukusetshenziswa kwe-belt slack kuvumela iphrofayili ye-tubular ukuthi isebenze ngaphandle kokuyicaba. Amanye amabhande anama-pulleys amathathu okuxhumana, okuvumela ukuguquguquka okwengeziwe eduze kweshubhu. Amabhande atholakala ngosayizi abahlukahlukene. Amabhendi wefayela asukela ku-18″ ukuya ku-24″, kuyilapho i-King-Boa idinga amabhendi angu-60″ ukuya kwangu-90″. Amabhande angenasikhungo nayisilinda angaba amayintshi angu-132 ubude noma ubude futhi afike kumayintshi angu-6 ububanzi.
Inkinga ngamathuluzi ezandla ukuthi ukuthola isiphetho esifanele ngokuphindaphindiwe kuwubuciko ngaphezu kwesayensi. Ama-opharetha anolwazi angafinyelela ukuqeda okuhle kakhulu ngale ndlela, kodwa kudinga ukuzijwayeza. Ngokuvamile, isivinini esiphezulu sibangela ukuklwebheka okuhle, kuyilapho isivinini esiphansi siholela ekuklwebeni okujulile. Ukuthola ibhalansi yomsebenzi othile kuncike ku-opharetha. Isivinini sokuqala se-tape esinconywayo sincike endaweni yokugcina oyifunayo.
Kodwa-ke, kubalulekile ukugwema ukusetshenziswa kwe-disc noma izigayi zezandla zanoma yiluphi uhlobo lokucubungula amapayipi. Kunzima ukuthola iphethini oyifunayo ngalawa mathuluzi, futhi uma uphusha ukudayela kanzima kakhulu, kungathinta ijometri futhi kudale indawo eyisicaba epayipini. Esandleni sokunene, uma inhloso kuwukupholisha indawo yesibuko esikhundleni sephethini yokuklwebheka, izinyathelo eziningi zokugcotshwa kwesihlabathi zizosetshenziswa futhi isinyathelo sokugcina kuzoba inhlanganisela yokupholisha noma induku yokupholisha.
Ukukhethwa kwe-abrasive kudinga ukuqonda okucacile kokuqeda kokugcina. Yiqiniso, lokhu kulula ukukusho kunokukwenza. Ukuhlola okubonakalayo kuvame ukusetshenziselwa ukufanisa izingxenye nemikhiqizo ekhona. Kodwa-ke, umhlinzeki wesitolo onama-abrasive angasiza ekunqumeni ukuthi kungcono kanjani ukunciphisa kancane kancane inani le-abrasive ukuze kuzuzwe umphumela oyifunayo.
Lapho ugaya insimbi engagqwali kuze kube sekugcineni, kubalulekile ukusebenzisa inqubo yokugwaza ethatha isinyathelo. Ekuqaleni, ufuna ukwenza isiqiniseko sokuthi wonke amabala namazinyo ayasuswa. Sifuna ukuqala ngomkhiqizo ongcono kakhulu ukubhekana nalokhu kushiyeka; lapho ukunwaya kujula, kudingeka umsebenzi owengeziwe wokukulungisa. Esinyathelweni ngasinye esilandelayo, ukunakekelwa kufanele kuthathwe ukuze kukhishwe imihuzuko ku-abrasive yangaphambilini. Ngakho-ke, iphethini yokuklwebha iyunifomu ifinyelelwa kumkhiqizo oqediwe.
Ngama-abrasive ajwayele ukunamathela, kungase kube nzima ukweqa amamaki abrasive ukuze uthole isiphetho esilungile se-matte kunsimbi engagqwali ngenxa yendlela ukuphuka kwe-abrasive. Kodwa-ke, obunye ubuchwepheshe bukuvumela ukuthi weqe izinyathelo, ezifana nama-abrasive e-3M's Trizact, agqoka ngendlela yokuthi i-abrasive "ivuselelwe" ngokusanhlamvu okusha obala njengoba kusetshenziswa. 3M
Yiqiniso, ukunquma izinga lobunzima be-abrasive kuncike ezintweni. Uma udinga ukususa iziphambeko ezifana nesikali, amadents noma imihuzuko ejulile, uzodinga ukusebenzisa i-abrasive emahhadla. Isibonelo, sivamise ukuqala ngebhande le-3M 984F noma le-947A. Lapho sesithuthele kumabhande angu-80 egrit, sashintshela kumabhande akhethekile.
Uma usebenzisa ama-abrasives amboziwe endabuko, qiniseka ukuthi unciphisa ukuhlukaniswa kwe-abrasive ngayinye ngaphandle kokuphuthelwa ngenxa yokuthi i-abrasive iphuka kanjani ukuze uthole ukuqedwa kwe-matte okulungile ensimbi engagqwali. Uma i-abrasive iphuka, ingcindezi eyengeziwe iyadingeka ukuze kuzuzwe umphumela ofanayo njengoba amaminerali eba mnyama noma ekhishwa ku-abrasive. Amaminerali ama-matte noma amandla aphezulu akhiqiza ukushisa. Ngenxa yokuthi ukushisa kuyinkinga uma uqeda insimbi engagqwali, kungathinta isiphetho kanye “nobuluhlaza okwesibhakabhaka” ebusweni.
Olunye udaba olungavela ngama-abrasives ashibhile ukuhambisana kokuqedwa kwawo amaminerali. Kuzoba nzima ku-opharetha ongenalwazi ukuqinisekisa ukuthi i-abrasive ithola indawo efunekayo esinyathelweni ngasinye. Uma kukhona ukungqubuzana, imihuzuko yasendle ingase ibonakale ingase ingabonakali kuze kube yisigaba sokupholisha.
Nokho, ezinye izindlela zikuvumela ukuba weqe izinyathelo. Isibonelo, i-3M's Trizact Abrasive isebenzisa ingxube ye-resin kanye ne-abrasive ukudala isakhiwo se-pyramidal esivuselela indawo elimazayo ngezinhlayiya ezisanda kuvezwa njengoba i-abrasive igqoka. Lobu buchwepheshe buqinisekisa isiphetho esingaguquki kuyo yonke impilo yebhande. Ngenxa yokuthi ibanga ngalinye le-Trizact tape linikeza ukuphela okungabikezelwa, sikwazile ukweqa amamaki alimazayo ekugcineni. Lokhu konga isikhathi ngokunciphisa izinyathelo zokuthungatha isihlabathi kanye nokunciphisa ukusebenza kabusha ngenxa yenhlabathi engaphelele.
Ukhiye wokukhetha i-abrasive ukunquma ukuthi ungayithola kanjani isiphetho esifanele ngesikhathi esiningi nangendlela eyongayo.
Njengoba insimbi engagqwali iyinto enzima, ukukhethwa kwe-abrasive namaminerali kubaluleke kakhulu. Uma usebenzisa i-abrasive engalungile, uma izinto zicutshungulwa isikhathi eside, kukhiqizwa ukushisa okwengeziwe. Kubalulekile ukusebenzisa uhlobo olulungile lwe-mineral kanye nokusebenzisa i-abrasive ene-heat dissipative coating ukuze kukhishwe ukushisa endaweni yokuxhumana lapho kufakwa isihlabathi.
Uma usebenzisa umshini, ungasebenzisa nengxenye yokupholisa, esiza ukususa udoti, ukuqinisekisa ukuthi imihuzuko yemfucumfucu ayilimazi indawo engaphezulu. Qiniseka ukuthi usebenzisa isihlungi esifanele ukuze udoti ungaphindi ungene lapho okokupholisa kuzuliswa kabusha emshinini.
Abantu abaningi bacabanga ukuthi yonke insimbi engagqwali ibukeka ifana, kodwa uma kuziwa endaweni eqediwe yengxenye, izinhlobo ezimbili zamaminerali zingathinta ukubukeka kwaleyo ngxenye. Lokhu kubuka kuncike kumsebenzisi.
Isibonelo, i-silicon carbide yendabuko ijwayele ukushiya imihuzuko ejulile ebonisa ukukhanya ngokuhlukile futhi ikwenze kube luhlaza okwesibhakabhaka.
Ngesikhathi esifanayo, i-aluminium oxide yendabuko ishiya umumo oyindilinga kakhudlwana obonisa ukukhanya ngendlela ehlukile futhi enze into ibe phuzi.
Kuye ngobukhulu bepayipi, i-grinder yebhande ingaba yindlela ephumelelayo yokuqinisekisa ukuthi ingxenye yejometri ayishintshi ngesikhathi sokuqeda. Ukusetshenziswa kwe-belt slack kuvumela iphrofayili ye-tubular ukuthi isebenze ngaphandle kokuyicaba. 3M
Ukwazi ukuphela okudingekayo kwengxenye kubalulekile ngoba izinhlelo zokusebenza zivame ukudinga izingxenye ezintsha ukuze zifane nezikhona.
Insimbi engagqwali iyimpahla ebizayo, ngakho ukukhetha ngokucophelela amathuluzi okuqeda kubalulekile. Ukwesekwa okufanele okuvela kubahlinzeki-mpahla kungasiza izitolo zithole izindlela zokonga isikhathi nemali.
